Friedrich’s ductless line of products will happily replace their gas or expensive electric heaters with extremely efficient heat pump operation all the way down to 0°F. While typical heat pumps only operate down to ~40°F before switching into “Emergency heat” electric heat mode, Friedrich heat pumps can continue to work for 40 more degrees, offering Heating Seasonal Performance (HSPF) ratings as high as 11.00. Heat pumps work by taking the heat energy from the outdoor and transferring it to the indoor space using refrigerant (R-410A). While it’s true that colder outdoor temperatures make it harder to find heat to remove, their Precision Inverter will find any heat available and transfers it into their customer's home. Friedrich Heat Pump According to recent studies by the Northeast Energy Efficiency Partnerships, “When entire units are replaced, the annual ASHPs savings are around 3,000kWh (or $459) as compared to electric resistant heaters and 6,200kWh (or $948) as compared to oil systems. When displacing oil (i.e. the oil system remains, but operates less frequently), the average annual savings is near 3,000 kWh (or about $300).” When one lives in an area that experiences snow and ice during the winters, it’s recommended that the outdoor unit be placed in an area either higher than one’s anticipated snow depth or placed in a structure that keeps it clear of snow, so the system will not get blocked by snow or ice. Don’t be fooled by harsh winter conditions, condensers can be installed indoors. Customers in the Northeast Region of the US have installed Friedrich’s condensers in their garage so they can enjoy the deep winter savings of a Friedrich Heat Pump air conditioner into the single-digit and negative temperatures.
Amid concerns about the increasing scope of the coronavirus (COVID 19), International Institute of Ammonia Refrigeration (IIAR) has announced the cancellation of its 2020 IIAR Natural Refrigeration Conference & Heavy Equipment Expo, a major industry event focused on natural refrigerants in the industrial and commercial sectors. IIAR Conference cancelled IIAR joins a growing list of HVAC&R organizations worldwide that have cancelled trade gatherings over the coronavirus. The IIAR Conference had been scheduled to take place March 15-18 at the Rosen Shingle Rosen Shingle Creek Hotel and Convention Center in Orlando, Florida (U.S.). Last year’s conference in Phoenix, Arizona (U.S.) had over 1,700 in attendance, according to the IIAR website. IIAR joins a growing list of HVAC&R firms worldwide that have cancelled trade events over the coronavirus IIAR had indicated its intention this week to proceed with the event, but changed course on March 11 after the World Health Organization (WHO) declared that the coronavirus was a worldwide pandemic. “Given this significant announcement from the World Health Organization, we have made the difficult decision to cancel the conference this year,” said Dave Rule, President, IIAR in a message emailed to registered conference attendees. “The health and safety of the conference attendees remains our primary concern.” Coronavirus pandemic threat “We trust that all of you will understand this decision and support your IIAR organization as the Executive Committee and Board of Directors begins to deal with this dramatic event,” he added. IIAR’s Executive Committee had begun developing plans “to address appropriate measures moving forward,” said Rule. “Further information concerning the cancellation of the IIAR Conference will be available over the course of the next few weeks”, Rule said, adding, “We request your patience and support as the IIAR Staff and management deal with these issues.” Global HVACR events cancelled Elsewhere in the world, two other HVAC&R industry trade shows scheduled in March were canceled, Mostra Convegno Expocomfort (rescheduled to September 8-11) in Italy and HVAC&R Japan. HVACR Live, scheduled to take place April 20-22 in London, was postponed till the spring of 2021. In addition, the ARBS (Air Conditioning, Refrigeration Building Services) 2020 exhibition in Melbourne, Australia, scheduled for May 19‐21, has been postponed.
Air conditioning professionals attending this year's AHR Expo had the opportunity to preview Danfoss' extensive portfolio of rooftop components that unite to help OEMs tackle seasonal efficiency and refrigerant changes—including innovations like the Interlaced Micro Channel Heat Exchanger (iMCHE). Designers of rooftop units are facing a pair of environmental challenges: the US Department of Energy's 2023 energy efficiency standards requirement of a 15% increase in integrated energy efficiency ratio (IEER), and the introduction of regulations by a growing number of states to replace HFC refrigerants like R-410A with lower-GWP alternatives. Part-Load Efficiency And Switch Refrigerants At AHR Expo 2020, Danfoss showcased a substantial portfolio of components that solve these challenges by helping manufacturers improve part-load efficiency and switch refrigerants, often with minimal redesign costs, and shared with visitors the system-level benefits revealed in laboratory tests. Danfoss iMCHE enables several circuits to share the heat transfer area in a single coil Several of the innovations and solutions combine to give OEMs an immediate boost in part-load efficiency. Some of the components can achieve savings of more than 15% on their own, helping OEMs meet the more stringent 2023 IEER regulations. Heat-Transfer Efficiency The Danfoss iMCHE enables several circuits to share the heat transfer area in a single coil, improving part-load efficiency by more than 20%, maximizing heat-transfer efficiency, and reducing refrigerant charge in a compact shape which minimizes weight. The third-generation VZH variable-speed inverter scroll has a higher part-load performance and wider operating map than ever before. The scrolls range from 4 to 26 TR, which can be further expanded to 52 TR in a hybrid tandem, and, like all Danfoss inverter scrolls, now include Intermediate Discharge Valve (IDV) technology for maximum part-load efficiency. Compressor Control Logic The powerful new MCX15B2 and MCX20B2 controllers are ideal for use in rooftop units. As enhanced versions of the popular MCX-B-series units, they offer best-in-class connectivity and safety, along with new compressor control logic for industry-leading Danfoss VZH inverter scrolls, enabling system designers to get the biggest possible benefit from variable-speed compression in any conditions. Danfoss manifolds are designed to minimize OEMs’ system losses, and are assembled in Danfoss facilities Pre-assembled tandem and trio manifolds enable OEMs to improve their system’s seasonal efficiency while reducing complexity in the supply chain and manufacturing processes. Danfoss manifolds are designed to minimize OEMs’ system losses, and are assembled in Danfoss facilities using the highest quality manufacturing techniques to ensure reliability. They include multiple combinations in even and uneven tandems and trios, and hybrid tandem configurations—and all feature patented Organ Pipe technology for optimized oil management under part-load conditions. Multi-Refrigerant DSH Scrolls With more than half the US population living in a state included in the United States Climate Alliance, many manufacturers are working on two or more rooftop configurations in parallel—one using R-410A, and one using refrigerants with a GWP rating of 750 or less, such as R-452B, R-454B, or R-32. As there is no single, clear R-410A replacement, visitors to AHR Expo 2020 were able to discuss with Danfoss experts the ways to maximize refrigerant flexibility. Multi-refrigerant DSH scrolls are qualified for use with refrigerants R-454B, R-452B, R-410A, enabling multi-refrigerant drop-in support while minimizing inventory and redesign requirements. Like Danfoss VZH scrolls, they include IDV technology to improve IEER. Danfoss Colibri® Electric Expansion Valves DSH scrolls are just one part of Danfoss' extensive range of multi-refrigerant components qualified for use with low-GWP A2L refrigerants. For example, Danfoss Colibri® electric expansion valves are qualified for use with more than 30 refrigerants—including R-410A, R-32, R-452B, R-454B, and R-1234yf. This flexibility enables manufacturers to benefit from precise liquid injection in a light, easy-to-install format, without a need to redesign their system for each refrigerant. ETS Colibri will also benefit from its own power back module, the EKE2U, to be released later in 2020, to enhance system reliability in case of unplanned system shutdowns. Victor Marinich, Global Marketing Director—Air Conditioning at Danfoss, said: "The need to protect our environment means rooftop manufacturers are responding to a fast-moving regulatory landscape.The best part is, these components all work together perfectly. That means you can use them to create a big, cumulative impact on part-load efficiency, while also maximizing reliability."
In response to a global shift away from R410A and R22, Danfoss has added a complete portfolio of components to help OEMs develop air conditioning systems with R32. With its relatively low global warming potential (GWP) at GWP-675, high volumetric capacity and efficiency, lower purchase price and system charge, R32 has become one of the most popular alternatives—along with R452B and R454B—to R410A for commercial air conditioning systems and heat pumps. In response to high demand—and following the release of the multi-refrigerant portfolio for R410A/R452B/R454B earlier this year—Danfoss has announced a full range of components that enable OEMs to design R32 systems up to 700kW/260TR. The portfolio includes: DSF fixed-speed scroll compressors with IDVs, optimized for R32 – full range available by the end of 2020 Micro plate heat exchangers (MPHE-Z design), optimized for R32 – full range available by the end of 2020 Micro channel heat exchangers (MCHE) adapted for R32 The Colibri Electronic expansion valve (ETS C), TGE and TR6 expansion valves for the US residential units System protectors and line components such as NRV check valves, GBC ball valves, STF 4 way valves, EVR v2 solenoid valves, ACB switches and DST P110 sensors, DML and DCL for residential and DCRE filter driers for larger air conditioning units, SG sight glasses, all qualified for R32. Compatibility has been checked with every raw material and connections over 25mm are all validated according to PED category II except for the EVR v2 and with US approval. seasonal efficiency requirements Importantly, Danfoss’s scroll design enables OEMs to take full advantage of R32’s thermodynamic properties, with +10% volumetric capacity for a same compressor size. This optimized design improves the $/TR-€/kW ratio. It also mitigates the impact of high discharge gas temperature, without the need for costly liquid or vapor injection—a significant applied cost benefit – and enables a wide operating map, suitable for use in reversible systems. And like Danfoss’s DSH multi-refrigerant range, the DSF range is equipped with intermediate discharge valve (IDV) technology to meet the latest seasonal efficiency requirements. Matthieu Stoll, Danfoss Cooling, AC Segment Marketing Director said: "Around the world, air conditioning OEMs are switching away from R410A. By adding a new R32 range of products on top of our existing multi-refrigerant R410A/R452B/R454B portfolio, we’re committed to providing the broadest range of options to our customers.”


Editor's Note
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.
