Refrigerants used in cooling systems for homes and businesses are being replaced with alternatives that have less potential for global warming. But the transition comes at a risk: Some of the new refrigerants are flammable. Although less flammable than gases such as propane, for example, new refrigerants can still ignite and burn with a high intensity under ideal circumstances. The new materials have low-flame velocity and are less easily ignited; however, one byproduct of combustion is t...

Sensaphone® introduces a new combination temperature, humidity and CO2 sensor that measures and provides real-time values to any Sensaphone monitoring device that accepts a 4-20 mA or MODBUS signal. When the sensor registers that a monitored condition falls outside of the programmed range, the system sends an alert with the current value to the operator. This convenient new sensor utilizes a highly accurate and reliable dual-channel non-dispersive infrared (NDIR) sensor to monitor CO2, a precision thermistor to monitor temperature, and a thermoset polymer-based capacitance sensor to measure humidity levels. Running multiple combination sensors User-friendly features include an LCD display for configuring the sensor and viewing readings. Each combination sensor is encapsulated in a pod that users can easily replace in the field. It is protected from moisture by an IP65-rated enclosure that operators can either mount on a wall or suspend from the ceiling. Depending on the type of Sensaphone monitoring system, operators can choose either a 4-20 mA or MODBUS-compatible combination sensor and select to receive alerts via phone call, email or text message. For MODBUS systems, users can run multiple combination sensors in parallel.
RenewAire®, a manufacturer of HVAC and IAQ products, has added a dedicated outdoor air system (DOAS) with integrated refrigeration to its DN Series of outdoor air equipment. The DX-based DN Series DOAS with Integrated Refrigeration (IR) is a modular, flexible design that’s customizable with thousands of configurations available to design engineers. The DN Series DOAS with IR’s renowned static-plate enthalpy cores feature a near-zero exhaust air transfer ratio (EATR) at balanced airflow that’s an ideal outdoor air solution for healthcare, retail, office, education and most commercial building markets. Providing Minimum Cooling Operation The DN Series DOAS with IR is a compressorized outdoor unit that boasts an 8.0 ISMRE rating The design is especially beneficial for those applications using chilled beams, VRF/VRV, radiant panels and other technologies lacking adequate latent load management capabilities. The DN Series DOAS with IR is a compressorized outdoor unit that boasts an industry-pioneering 8.0 ISMRE rating. This efficiency is partly due to its brushless DC compressors, EC motors on both the supply and exhaust fans, and options for a draw-through or a plenum push-through airflow, the latter which provides a better cross-sectional air delivery and up to 95-percent coil coverage. The three-model series–D-2, D-3 and D-5–ranges from 375 to 5,000-CFM and two to 30-tons of refrigeration. Models with refrigeration capacities above 10-tons, offer the option of two compressors. In this configuration, the brushless DC variable speed compressor is the primary workhorse and efficiently provides minimum cooling operation parallel to partial load needs. Cross-Sectional Air Delivery On approaching 100-percent, the fixed speed compressor automatically activates and the variable speed compressor shifts to partial loads when additional outdoor air and recirculation conditioning is required. The compressors, as well as other components, are factory-piped and balanced using calculations based on the climatic outdoor air conditions of their application destination. The series offers the designer nearly any conceivable configuration to maximize air comfort The series offers the designer nearly any conceivable configuration to maximize air comfort as well as energy efficiency, such as recirculation and bypass dampers, night setback, economizers, a myriad of heating options and other configurability. Besides a traditional draw-through airflow configuration, engineers also have the option of a plenum fan blow-through that provides a better cross-sectional air delivery and up to 95-percent coil coverage. The DN Series DOAS with IR can operate as a stand-alone 100-percent outdoor air HVAC unit, or as a make-up air role in conjunction with an RTU for controlling sensible and latent load management. Imaginable Primary HVAC Application The DN-Series’ is certified under AHRI-1060 and fulfills requirements of ASHRAE Standard 90.1 and the International Energy Conservation Code (IECC). It can also add to a project’s LEED® credits as well as qualify for WELL Certified® and WELL Compliant® standards. The DN Series DOAS with IR’s other features are: Operates down to 49°F (9.4°C) supply air dew point conditions, which facilitates outdoor supply air management of the indoor humidity loads; Cabinets are available in one-inch-thick (25.4-mm) R-6, or two-inch-thick (50.8-mm) R-13 thermal-break foam-insulated double walls constructed of sturdy 20-ga. galvanized steel with optional paint-rated for 2,500-hour salt spray protection; Flexible, modular configurability offering mix-and-match combinations of a variety of cooling coil methods, heating sections and fan strategies; Compatibility with almost any imaginable primary HVAC application, such as direct expansion (DX), chilled water for the cooling coil. Heating section offers electric (SCR), indirect gas furnace (5:1, 10:1 modulation), hot water, steam, or a self-contained, DDC-controlled modulating hot gas reheat option; Negates the need for defrost cycling under normal operating conditions, however a defrost mode is available for extreme combinations of high indoor humidity and low outdoor ambient temperatures; Availability with a factory-supplied curb; AMCA Class 1 (low leakage) isolation dampers, internal enthalpy bypass damper and an optional unoccupied recirculation damper; Standard 2-inch (50.8-mm) MERV 8 filters, however MERV 13, MERV 14 and 4-inch (101.6-mm) filters are optional. Energy-Intensive Purge Cycles RenewAire’s proprietary static plate core is its competitive edge. It operates at a low EATR without requiring energy-intensive purge cycles. With no moving parts, the failsafe static plate dehumidifies more efficiently versus an enthalpy wheel, which requires parasitic power for motorized rotation. The DN Series also carries a performance warranty that guarantees the original operating specifications While wheel technology inherently suffers maintenance and reliability costs, RenewAire’s static plate boasts the HVAC industry’s best uptime performance that’s backed by a 10-year warranty. Additionally the DN Series also carries a performance warranty that guarantees the original operating specifications for 10 years without any degradation and a two-year warranty on the balance of the unit. Building Automation System The DN Series’ integrated, programmable controller is preset and programmed by factory engineers to the consulting engineer’s sequence of operation. The ‘plug-and-play’ unit requires only connection to facility power and the building automation system (BAS), which significantly reduces contractor installation time and eliminates jobsite programming errors. Its BACnet or Modbus platform allows great flexibility in controlling operational effectiveness and user activity indoors through any combination of RenewAire’s temperature, humidity, occupancy, static pressure, fire/safety, CO2 and IAQ sensor accessory options. The onboard controller also offers full programming and BAS override capabilities.

A key deadline for phasing out hydrochlorofluorocarbons (HCFCs) from residential air conditioning systems is less than a year away. Jan. 1, 2020, is the deadline after which there will be no U.S. production or import of HCFC-142b and HCFC-22 (also called R-22). The deadline is part of an incremental phazeout of HCFC consumption and production based on the U.S. commitment in the 1997 Montreal Protocol aimed at protecting stratospheric ozone. Section 605 of the Clean Air Act establishes phazeout targets for the chemicals. The phazeout will be complete in 2030, after which time there will be no production or import of any HCFCs. HCFC-142b retrofit refrigerant HCFC-142b is used in small quantities in refrigerant blends and as a retrofit refrigerant in motor vehicle ACs HCFC-142b is used in small quantities in refrigerant blends and as a retrofit refrigerant in motor vehicle air conditioners that previously used chloroflurococarbons (CFCs), which were eliminated in the mid-1990s for their potential to deplete the ozone layer. HCFC-22 is the most commonly used refrigerant in applications such as unitary air conditioners, cold storage, retail food refrigeration equipment, chillers and industrial process refrigeration. Any air conditioner or heat pump manufactured before 2010 likely uses HCFC-22 refrigerant. Hydrochlorofluorocarbons in air conditioning systems On Jan. 1, 2020, U.S. production or import of HCFC-22 and HCFC-142b will not be permitted in the United States. After this happens, only recycled/reclaimed or stockpiled quantities of HCFC-22 and HCFC-142b will be available for servicing existing equipment, and they will likely be more expensive. These substances have been in the process of being phazed out since 2015, when supplies were reduced by 90 percent. Since 2010, HCFC-22 and HCFC-142b have been available exclusively for use to service existing equipment. There are several non-ozone-depleting alternatives to HCFC-22. They include R-134a and R-410A, which can be used in a new installation; and R-407C and R-407A, which can be used in a new or a retrofit installation. The most common alternative is R-410A, which is manufactured and sold under various trade names such as GENTRON AZ-20, SUVA 410A, and PURON. Significant New Alternatives Policy SNAP (Significant New Alternatives Policy) was established by the U.S. Clean Air Act to identify and evaluate substitutes for ozone-depleting substances. The program looks at overall risks to human health and the environment of existing and new substitutes, publishes lists and promotes the use of acceptable substances, and provides the public with information. EPA reviews alternative refrigerants and maintains a list of acceptable substitutes for household and light commercial air conditioning. For the last 25 years, the air conditioning and refrigeration industry has been working to reduce its use of CFC refrigerants, which are no longer available on new equipment. The industry has used alternative refrigerants and achieved higher efficiency ratings to achieve the goals. CFC refrigerants Long life of AC equipment has extended the continuing use of CFC refrigerants by existing equipment However, the long useful life of air conditioning equipment has extended the continuing use of CFC refrigerants by existing equipment. Green building groups have supported legislative action to reduce federal depreciation schedules for this equipment, which would accelerate the replacement of older equipment and hasten the total elimination of CFC refrigerant use. The HEAT Act, which Congress passed in 2017 as part of the landmark Tax Cuts and Jobs Act, reduced commercial HVAC expensing from 39 years to immediate (zero years). Phazing out ozone-depleting refrigerants The European Union is also committed to protecting the ozone layer and has some of the strictest regulations in the world. Since 2010, there has been a ban on the use of “virgin” HCFCs to service and maintain refrigeration and air conditioning equipment; use of reclaimed or recycled HCFCs for service or maintenance has been banned since 2015.
When Pine Valley Ranch, a Spencerville, Ohio-based egg-breaking facility was looking for an energy efficient way to wash 600 cases of eggs an hour they turned to Consolidated Hunter, a local heating contractor, and Pickrel Brothers, a provider of industrial heating supplies to help present options. Their recommendation? Install six Weil-McLain SlimFit 750 commercial high-efficiency hot water boilers. “We’re an egg-breaking plant,” explains Evan Fleck, an owner of Pine Valley Ranch. “Our eggs come straight from the barn and are immediately washed. Then they are broken, separated and chilled. Once this is done, they are loaded into liquid tankers and shipped to be pasteurized. Every step of the process is important, especially the washing of the eggs. We need plenty of hot water for that, as well as for other daily operations.” Efficient production process The 4.5 million BTU/hour Pine Valley heating system supports seven individual heating zones The 4.5 million BTU/hour Pine Valley heating system supports seven individual heating zones. The first three zones are dedicated to the egg washing machines and supported with 750 BTU/hour boilers. The fourth and fifth zones support the clean-in-place equipment (990,000 BTU/hour heat exchangers) while the two remaining zones are for the indirect fired water heater and the on-site plant mixing station. “Every zone is critical to ensuring a high-quality, efficient production process,” says Fleck. “We have more than 900,000 chickens at this facility and they produce a lot of eggs. The Weil-McLain boiler systems provides a consistent source of hot water to accommodate this large number.” Wide range of commercial installations SlimFit boilers have been serving the heating industry since 2009 with rugged, cast horizontal heat exchanger sections that provide thermal efficiencies up to 95.8% (SlimFit 1000 & 1500 models). The boilers feature a low pressure drop design, with large water passageways to accommodate a wide range of commercial installations, including retrofit and replacement applications with older water systems. Other standard features include a composite condensate tray for heat exchanger longevity The larger SlimFit 1000-2000 models feature a narrow ‘door-fit’ profile and integrated roller casters for improved installation maneuverability in confined spaces and weight restricted areas, saving contractors time and money. Other standard features include a composite condensate tray for heat exchanger longevity, customizable control mounting location (front or side) and leveling legs, which mitigate the need for a concrete service pad. Typical heating operation conditions Control features include a setup wizard that guides the installer through the start-up process and 10 preset typical heating operation conditions. The SlimFit also features zone stacking up to 24 programmable zones without the need for additional external panels and 0-10 VDC analog output signal for easy integration with a lag boiler in a hybrid system. “We really appreciate how the Weil-McLain boiler-system enhances our operation,” says Fleck. “The equipment was installed when the facility was built so they’ve been part of our production process from the beginning. Running a plant of this size always presents challenges, but our hot water needs are not one of them.”
The University of Texas at Austin first opened its doors in 1883 with eight professors, 221 students and a goal of creating quality higher education in the state of Texas. Throughout the last 135 plus years, UT Austin has grown to over 3,000 professors, 51,000 students and has garnered an impressive global reputation. Regardless of growth, the university takes pride in its active attention to pursuing sustainable energy solutions. In the interest of reducing the impact the university has on the local grid and environment, the Carl J. Eckhardt Combined Heating and Power Complex was built to provide energy for the campus. Energy Production Efficiency The system uses the same amount of fuel today as in 1976 with double the amount of served space This power plant has achieved an efficiency of more than 85%, meaning very little energy is lost in the form of heat. This is more than twice the efficiency of a typical power plant. With all of the advancements in efficiency, the system uses the same amount of fuel today as in 1976 with double the amount of served space. Because the energy production efficiency is more than 85%, annual savings opportunities are now on the demand side. In 2010, the Energy Management & Optimization (EMO) team at University of Texas at Austin began a 20-year plan to reduce the average energy use intensity (EUI) on the main campus by 20%. The goal was met early in 2018, so a new goal was set for at least 2% annually. This reduction in energy consumption has been taking place even while the university continues to grow. Achieving Higher Levels Of Sustainability Through initiatives, such as replacing halogen lamps with LEDs in the Texas Memorial Museum and behavioral programs encouraging students to turn off lights, UT Austin has been consistently meeting their goal of optimizing energy consumption. This allows UT Austin to reduce operating costs and achieve higher levels of sustainability. With UT Austin’s continuous growth comes an ever-evolving need for facilities With UT Austin’s continuous growth comes an ever-evolving need for facilities. Recently, UT Austin converted an old technology incubator facility with dense equipment cooling loads, known as the West Pickle Research Center, into new office spaces for faculty. Because the offices do not require as much cooling as the lab, the two constant-speed, oil-lubricated, centrifugal chillers that had previously supported the building were no longer appropriate. There was a 650 ton (2,285 kW) chiller that provided too much cooling, and a 200 ton (703 kW) unit that did not provide enough. Highly Efficient And Optimized Solution The chillers were installed in 1983 and ran on R-11, an ozone depleting refrigerant that is now banned for use in new equipment via Montreal Protocol. The chillers were past due for an upgrade and operating them wasted a lot of energy. Johnson Controls offered a highly efficient and optimized solution with a 300 ton (1,055 kW) YORK® YZ Magnetic Bearing Centrifugal Chiller. Installed in 2018, the chiller provided a perfect middle ground between the two previous chillers and was fondly nicknamed the ‘Goldilocks Chiller’ because it was just the right size for the new building load. With the flexible control options that the variable speed drive offers to meet a shifting building load, unnecessary energy consumption was curbed. Additionally, the magnetic bearing technology in the YORK® YZ dramatically increases reliability, decreases downtime and decreases the need for maintenance. Low Tower Water Temperatures The high efficiency of the YZ makes an appreciable difference in energy costs The UT Austin EMO Team appreciates the independence of the YZ chiller, saying, “We never have to worry about changing filters or checking oil levels, which allows us to focus our energy on saving initiatives rather than the upkeep of equipment.” While operating the YZ Chiller, UT Austin realized an estimated 330,000 kWh or $23,000 annual savings. The high efficiency of the YZ makes an appreciable difference in energy costs over the year compared to the old chillers previously in the building. One of the reasons the YZ chiller can save energy throughout the year is its ability to run at exceptionally low tower water temperatures, thanks to its wide operating map. Reducing Energy Consumption “We used to have to hold the entering condenser water temperature at 65°F (18.3°C) to run our chillers during the winter months, but the YZ Chiller is able to take advantage of our entering condenser water temperatures down to 45°F (7.2°C), greatly reducing the energy consumption.” The YZ is designed for real-world efficiency and operates efficiently at off-design conditions Utilizing magnetic bearings eliminates minimum speeds and lubrication systems that previously limited chillers from operating at extra low lift conditions. The YZ is designed for real-world efficiency and operates efficiently at off-design conditions, which is where chillers operate 98% of the time. Even in a warmer climate like Austin, Texas, there are still plenty of hours where the temperature is cool enough to take advantage of lower entering condenser water temperature. Sophisticated Building Technology While the chiller has been operating, exceptional efficiencies as low as 0.15 kW/ton (23 COP) have been observed. An impressive feature of the YORK® YZ Chiller is its ability to easily integrate into any building setting and run efficiently. In this retrofit to an old lab facility, an immediate efficiency improvement of 15% over UT Austin’s other fully optimized plants was noted soon after starting up the YZ Chiller. Juan Ontiveros concludes, “It can support anyone in any system of any age. You don’t need the most sophisticated building technology to run the YZ and realize awesome efficiencies!”
Carmarthenshire-based food wholesaler Castell Howell has become one of Carrier Transicold’s first UK customers to take delivery of the Vector® HE 19 (High Efficiency), the company’s new flagship trailer refrigeration unit. The new arrival forms part of a larger order of Carrier Transicold systems all aimed at lowering the carbon footprint of the company’s commercial vehicle fleet: Carrier Transicold is a part of Carrier, a global provider of innovative HVAC, refrigeration, fire, security and building automation technologies. Engineless Refrigeration Solution The new Vector HE 19 MT (multi-temperature) is mounted to a 13.6-metre double deck trailer – the company’s third – which are all manufactured by Gray & Adams and cooled by Carrier Transicold. It’s always very exciting to be at the forefront of new technology in our industry" As part of Castell Howell’s continuing sustainability drive, six new 15-tonne DAF LF rigid trucks, fitted with Solomon bodies and Carrier Transicold ICELAND TWINCOOL refrigeration systems, will enter service later in the year. The new vehicles represent Castell Howell’s first use of Carrier Transicold’s engineless refrigeration solution. “It’s always very exciting to be at the forefront of new technology in our industry,” said Martin Jones, director of transport operations, Castell Howell. Next-Generation Vector Unit “So getting the opportunity to be one of the first companies to use the next-generation Vector unit was obviously something we jumped at. We’ve been specifying Carrier Transicold equipment for close to 30 years, so we had absolutely no doubt the new Vector would match up to the high standards we have come to expect. Alongside the engineless options for the new rigids, it really was the next logical step for the fleet.” The new Vector HE 19’s ultra-modern re-design includes significantly redeveloped internal architecture that cuts fuel consumption by up to 30 per cent, alongside a 10 per cent saving in weight and a noise reduction of 3 dB(A) – which to the human ear equates to a 50 per cent reduction in noise – as well as up to 15 per cent savings on maintenance costs. Lower Running Costs Castell Howell’s six new rigid trucks will also be joined by two new 7.2-tonne Iveco Daily light commercial vehicles “Our trailers operate on intense trunking routes all year round, so the ability to lower running costs across the total life of the unit was a huge draw for us. The reduction in fuel, weight and maintenance costs will all add up to significant savings over time. On top of that, it’s so quiet we have to keep checking it’s not actually on standby!” added Jones. Castell Howell’s six new rigid trucks will also be joined by two new 7.2-tonne Iveco Daily light commercial vehicles, each mounted with Carrier Transicold’s light-weight Pulsor® 600 MT. The new vehicles comprise a mix of additions and replacements to Castell Howell’s 150-strong commercial vehicle fleet.

Its fleet transports a range of ambient, chilled and frozen products across Wales and the south west of England.
Reynolds, one of the biggest fruit and vegetable suppliers in the UK, has taken delivery of two new specialist vehicles for operation inside London’s new Ultra-Low Emissions Zone (ULEZ). Both vehicles feature Carrier Transicold refrigeration technology and have been supplied by SHB Hire. Carrier Transicold is a part of Carrier, a globally renowned provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies. Engineless refrigeration system 95% of our fleet is Carrier-cooled, so when we set out to explore new ways of cutting our emissions" The new additions include a 26-tonne IVECO Stralis, with a body from Paneltex, mounted with a Carrier Transicold ICELAND 18 TWINCOOL refrigeration unit. A former demonstrator vehicle, it becomes the company’s first engineless refrigeration system in its truck fleet. It is joined by an all-electric Renault Kangoo van, fitted with Carrier Transicold’s ultra-slim NEOS 100, which also runs on electrical power, and converted by CoolKit. Together, the two systems directly support Reynolds’ plans to lower its commercial vehicle fleet emissions. “95% of our fleet is Carrier-cooled, so when we set out to explore new ways of cutting our emissions, we naturally put our faith in Carrier’s latest technologies,” said Steve White, head of fleet support, Reynolds. ICELAND TWINCOOL unit The undermount ICELAND TWINCOOL unit joins a truck and trailer fleet cooled by a range of existing Carrier Transicold products, including the proven Vector, Supra and Xarios ranges. It becomes the first system in the fleet to be driven by Carrier Transicold’s ECO-DRIVETM power module, which runs on hydro-electric power generated by the trucks’ ultra-clean Euro VI engine. Because it runs on the hydro-electric power generated by the engine, there is no need for a separate diesel engine, helping to cut emissions and improve fuel efficiency. The ICELAND stands out for its ability to supply 100% refrigeration capacity even at the truck engine’s idle speed, while keeping sound levels below 60 dB(A) for PIEK-compliance – a combination which makes it ideally suited to the intensive, multi-drop delivery routes Reynolds operates in London. NEOS 100 system The all-electric Kangoo van features Carrier Transicold’s roof-mounted, 12-volt NEOS 100 system The all-electric Kangoo van features Carrier Transicold’s roof-mounted, 12-volt NEOS 100 system designed to run entirely on electric power from the vehicle’s alternator. However, because an electric Kangoo does not use an alternator, an autonomous power source was supplied by conversion specialist, CoolKit. “To power the NEOS we fitted our own refrigeration power system, developed especially for these types of fridge van conversions,” said Cameron Javed, fleet sales specialist, CoolKit. “We specified this system because it does not draw power from the vehicle’s battery, meaning the range it can travel is not reduced and the unit can maintain power for longer.” NEOS’ monoblock construction The NEOS’ monoblock construction makes it simple to maintain, coming pre-charged from the factory with less than 1kg of refrigerant R134a. Its design avoids the need for assembly in the field or the use of open road compressors, which can both increase the risk of gas leakage in operation. Operating out of Reynolds’ depot in Waltham Cross, both vehicles will deliver fresh fruit and vegetables on multi-drop routes across central London, in operation up to 24 hours a day, seven days a week. Reynolds was established in 1945 and is a family-owned business with a 250-strong commercial vehicle fleet which it uses to supply the UK food service and catering industry. Carrier Transicold helps improve transport and shipping of temperature controlled cargoes with a complete line of equipment and services for refrigerated transport and cold chain visibility. CoolKit is a renowned manufacturer of refrigerated vehicles and utilizes innovative materials and advanced techniques to deliver temperature-controlled vehicle solutions.
