Control Systems: an Important Part in the HVAC Process
Control Systems: an Important Part in the HVAC Process

Control Systems have always played an important part in the function of HVAC systems and for many years were centered around the safe and optimum performance of the hardware deployed. Every HVAC system is a closed-loop process, with inputs fed into control logic that determines the best course of action to achieve the desired output. Energy management and integration into Building Information Management saw the advent of energy-saving techniques like free cooling and night-time purge reduce mechanical cooling loads, whilst occupation data allowed greater holistic management of systems. These are well-recognized practices that are being refined using predictive weather data, additional focus on heat recovery and more environmentally energy sources. Control Systems have always played an important part in the function of HVAC systemsThe scope of the typical systems loosely described above are around the management of systems on one site and their operation and maintenance tends to be centered around that particular location. Multi-site Development & Management The UK temperature-controlled warehousing market tends to develop on a project-by-project basis that fosters the site-by-site focus of ongoing management and maintenance. For multi-site logistics operators and manufacturers and distributors with a multi-site portfolio. this approach has the following disadvantages: Disparate system KPI data collection and reporting Setpoint adjustment left to untrained operators who apply their individual assessment of compliance risk and often don’t consider the financial and operational implications of fine-tuning (or meddling) Enterprise-wide energy management is difficult to control Duplication of staff tasked with reporting and maintenance Inconsistency of measurement and interpretation Slow response to system failures Poor interpretation of operational processes that impact system efficiency Portfolio Management The distinction here is that a portfolio of temperature-controlled sites is managed centrally instead of independently. The enabler to the solution is the rapid Energy management and integration into Building Information Management saw the advent of energy-saving techniquesdevelopment of access control systems and data communication. The next step is vital in the customer engagement process; what do they want to see? What’s important and what is not? How often do they want to see it and in what format? From experience of going through this process this is a voyage of discovery for the warehouse operator in understanding the stakeholders in their business. Quality and compliance managers are the obvious starting point, facilities managers, finance managers who are tasked with reducing energy costs, customer service and the end customer. Alongside the KPI monitoring, Jet Environmentals created a hierarchy of alarms management that alerts the right people with system information, that triggers a sequence of actions driven by the data. Trends are monitored to predict where there might be a problem on the horizon so action can be taken before there is an issue. Faults and failures are alerted instantly and corrective action alerts sent to the right people.  Conclusion The continuous development of HVAC controls and reliability of secure data connections has provided a means of improving performance, lowering cost and building trust in provider/user relationships. To be successful, the roll-out of such a project requires the willingness and collaboration of all parties and the groundwork defining stakeholder requirements is vital in defining a scope that meets expectations.

Smart Technology Brings Zone Comfort To Today’s Connected Homes
Smart Technology Brings Zone Comfort To Today’s Connected Homes

Many of us are spending more time at home. Given that work and home lives are becoming more intertwined, it makes sense to create a “comfort zone” in the place where people spend the most time. I am speaking about the benefits of zoned HVAC comfort control through duct-free split systems.  Imagine offering your customers the ability to cool their bedroom at night without having to cool the whole house. Maybe they want to cool their home gym to 68 degrees while leaving the playroom at 76 degrees. Duct-free systems offer the ability to individually set preferred comfort settings for each individual zone or room in the home. Control the temperature, humidity and even the volume and direction of airflow, all according to personal preference.  Imagine offering your customers the ability to cool their bedroom at night without having to cool the whole house Pandemic trends During the pandemic, one trend we are seeing is more consumers adding duct-free systems to spare rooms to function as a home office or the conversion of a garage for a home theater or as a social-distanced gathering place for family and friends. There are many options today to meet all of these needs and more. LG offers a variety of stylish, duct-free indoor units ranging from a smoked glass mirror finish to traditional white. You can offer your customers the ability to customize their space with the Art Cool Gallery, a unit that looks like a picture hanging on the wall, allowing them to add their own artwork or photographs. With so many options, there is no reason not to have the comfort you deserve. Each unit is powered by an energy efficient inverter with heat pump technology – some offering up to 28 SEER. The SEER calculates air conditioning and heat pump cooling efficiency. The higher the number, the less you will spend on energy costs. These systems – many of which are ENERGY STAR® certified – are built with cost-savings in mind, so whether it is low installation costs or reduced lifetime costs, your customers will be surprised to see the money they will save with duct-free HVAC technology. app technology  “Smart” indoor units from LG come equipped with Wi-Fi capabilities and on some other models, this function can easily be added using a separate module. This allows control via the included wireless controller or from a smartphone. The free app for both iOS and Android is called LG ThinQ®. This is where we have a unique advantage over the competition. The app is the same communication platform used with LG home appliances and TVs. When a homeowner presses the “away mode” it will set all of the indoor HVAC units to their predetermined temperature, and at the same time other smart appliances in the home - refrigerator, dishwasher, washer and dryer - will be set to a low energy consumption mode. Imagine the savings! The app also allows the control of HVAC modes (Heating, Cooling, Dehumidification, Auto Changeover, or Fan Only), temperature, airflow direction/vane movement (up, down, side to side), fan speed and of course power (on/off).  Users can control one or several units and each can be set up for group control. For instance, a parent might want to control all of the zones in the house, but only give children control of their room. Duct-free units give everyone their own personal level of comfort. There is also the option of installing these units in rooms that are typically warmer in the summer months or difficult to keep cool as temperatures rise. A connected home LG units can also be voice-controlled when paired with Amazon Alexa or Google Home For a more connected home, any of the LG units can also be voice-controlled when paired with Amazon Alexa or Google Home. This offers the convenience and freedom to use simple commands to set a desired temperature in various areas, such as: “Alexa, set the master bedroom to 70 degrees,” or “Alexa, set the office to heating.” So how does it work? The inverter compressor can adjust the speed of the compressor in 1 hertz level increments to match the load. This allows the outdoor condenser to operate at the minimum-required hertz level to meet the load and achieves a desirable energy efficiency at lower sound levels. The indoor unit also maintains greater cooling and wicks the moisture from the air to provide lower humidity levels. The reward is monthly energy savings on utility bills. These duct-free systems allow homeowners to efficiently make the most of all available spaces.

Trane Helps Schools To Evaluate And Implement Indoor Air Quality Improvements In Their Buildings

As the school year progresses in various formats, Trane® – by Trane Technologies, a global climate innovator – introduces expanded services to help schools evaluate, implement and fund indoor air quality improvements in their buildings. Heating, ventilation and air conditioning systems (HVAC) play a critical role in creating proper indoor air quality. ASHRAE® guidelines to address COVID-19 in the reopening of schools indicate that making changes to the operation of HVAC systems can mitigate exposure to airborne contaminants. Healthy indoor air quality “As schools bring back students for part-time or full-time in-person learning, healthy indoor air quality is a chief concern alongside other safety practices including wearing masks and social distancing,” said Donny Simmons, president, Commercial HVAC Americas at Trane Technologies. “HVAC systems, properly applied, are an important aspect of addressing environmental concerns within a school.” A thorough assessment is a helpful starting point for schools to understand their indoor air quality needs A thorough assessment is a helpful starting point for schools to understand their indoor air quality needs. The Trane® Indoor Air Quality (IAQ) assessment focuses on four critical pillars of indoor air quality – dilute, exhaust, contain and clean. The fact-based assessment equips school building managers with a clear and cost-effective roadmap for improvements that will bring facilities into alignment with CDC and industry recommendations. Isolation space evaluation The Trane IAQ Assessment now includes a supplemental isolation space evaluation to help schools better prepare for scenarios where students or staff experience symptoms while on campus. The evaluation can help schools create an isolation space in line with industry recommendations, including stringent guidelines for air exchanges, negative pressurization and other criteria. Trane’s comprehensive suite of solutions address conditions and recommendations across all four critical pillars of indoor air quality, including cleaning the environment to actively reduce the number of microbiologicals that may be in the air or on surfaces. Air cleaning technologies range from high-rated MERV or HEPA filters, to Ultraviolet Germicidal Irradiation (UVGI) and photocatalytic oxidation. Air cleaning solutions Trane now offers Synexis®-made Dry Hydrogen Peroxide (DHPTM) solutions to K-12 schools in the U.S To meet the evolving needs of schools and increased demand for air cleaning solutions, Trane now offers Synexis®-made Dry Hydrogen Peroxide (DHPTM) solutions to K-12 schools in the U.S. to help reduce the presence of viruses, bacteria, and mold in the air and on surfaces. Synexis® is the sole developer of the process by which naturally occurring humidity and oxygen are taken from the air to create DHPTM, which reduces the presence of unwanted microbes that may be present in the air and on surfaces, continuously improving indoor air quality and surface cleanliness. Synexis® solutions can be integrated into a school’s existing HVAC system or used as a portable, standalone unit in any room to treat the air and any surface the air touches, making it an ideal application for school isolation spaces, classrooms and high traffic areas like cafeterias and hallways. Best air quality solutions “Our customers count on Trane to bring them the best air quality solutions and strategies available, and we’re pleased to expand our portfolio with Synexis® solutions for schools,” said Simmons. “Implementing HVAC best practices and innovative air cleaning technologies, such as Synexis®, are ways schools can go on the offensive to help improve indoor air quality and create more peace of mind for students, faculty, administrators and parents.” “For many schools, the central issue is not whether they need indoor air quality improvements, but how they will they fund them – especially in a year marked by many other unplanned expenses,” said Simmons. “Trane’s expanded and flexible financing options help school districts move forward with the indoor air quality improvements they need now.” Delivering fast implementation Trane K-12 experts help schools evaluate the most affordable ways to pay for IAQ upgrades Trane Integrated Funding Solutions (IFS) includes Leasing and Managed Services Agreement options with deferred payment plans and extended terms for qualifying school districts. Additionally, Trane K-12 experts help schools evaluate the most affordable ways to pay for IAQ upgrades, including leveraging CARES Act funding, grants, utility rebates, and other available resources. The program is designed to help address schools’ financial constraints by eliminating immediate out-of-pocket expenses, preserving working capital and other forms of credit and delivering fast implementation of needed improvements. With flexible funding support, school districts can make needed upgrades to maintain proper indoor air quality now and help minimize impacts on operating budgets. “It’s a complex time for schools, and there is no single solution for all environments,” said Simmons. “Every school may have different needs – and variables – when it comes to indoor air quality. The bottom line is schools should work with a trusted partner and take a strategic, fact-based approach to make the best use of their budget and investments.”

Thermo King By Trane Technologies Launches Cold Storage Solutions To Support COVID-19 Vaccine Distribution

Thermo King, by Trane Technologies, a global climate innovator, has expanded its portfolio of temporary storage solutions that can meet the unique requirements of global pharmaceutical companies developing COVID-19 vaccines. Thermo King is the global provider of intelligent end-to-end temperature-controlled cold chain solutions. Pharmaceutical companies in final-stage clinical trials anticipate they will require strict temperature controls to safeguard their products - down to temperatures as low as -70 degrees Celsius. Thermo King’s solutions can enable these companies and their distributors to ensure the efficacy of their products through the entire cold chain - from air transport to marine, rail, trailer, last-mile delivery and at storage points along the way. Cold Storage Solutions According to the World Health Organization, nearly 20 percent of temperature-sensitive health care products are damaged during transport, and 25 percent of vaccines reach their destination in a degraded state due to breaks in the cold chain. “Considering the urgent, global need for a COVID-19 vaccine, the world can’t afford breaks in the cold chain.” said Dave Regnery, President and Chief Operating Officer of Trane Technologies. “Our new Cold Storage Solutions can maintain temperatures of -70 degrees Celsius for an extended period of time, can be leveraged to help reduce degradation of a vaccination, and most importantly, could prevent vaccine ‘deserts’ or lack of accessibility.” temporary storage solutions Thermo King offers storage solutions that can substantially extend the life of dry ice, or eliminate the need altogether Thermo King and its worldwide partners can offer temporary storage solutions that maintain a set point down to -70 degrees Celsius, and can ensure end-to-end temperature control, security and traceability through state-of-the-art telematics. Additional storage solutions include refrigerated trailers, containers and portable cubes that can easily be scaled and repositioned to other locations as demand changes. In addition to launching Cold Storage Solutions, Thermo King has helped customers identify ways to maximize the range of dry ice, which is often used in vaccine transport and storage but has certain limitations. A container using dry ice to keep a product frozen may require re-icing if it sits for an extended length of time or is exposed to extreme ambient weather. Thermo King offers storage solutions that can substantially extend the life of dry ice, or eliminate the need altogether. temperature-Sensitive vaccine “We have been engaging pharmaceutical and transport companies, policymakers, regulators and other industry partners to discuss ways to strengthen the cold chain,” said Regnery. “We know that we can help mitigate risk - we have a long history in cold chain expertise, and are actively working to innovate and address the complexities and potential challenges of the mass distribution of a temperature-sensitive vaccine.”
