The Air-Conditioning, Heating, and Refrigeration Technology Institute
will lead a research project to characterize the heat-transfer and pressure-drop performance of new low-GWP refrigerants.
Elastocaloric cooling technology developed by University of Maryland researchers is environmentally friendly and could represent the next generation of cooling equipment.
As the phasedown of HFCs continues, contractors must remain vigilant against illegal activity and take steps to ensure they are using legal refrigerants.
Manufacturers are offering low-GWP refrigerant alternatives, as EPA is proposing a 700 GWP limit for most new comfort cooling chillers starting in 2025.
The ESCO Group's National HVACR Education Conference featured an extensive number of educational sessions covering the hottest topics in the HVACR industry, such as mildly flammable (A2L) refrigerants.
EPA proposed a new rule as part of its efforts to phase down the use of high-GWP HFCs. HVAC manufacturers expressed concern about some of the provisions in the new rule, including training, GWP limits, compliance deadlines, and sell-through periods.
End users are looking for more from their systems than just reliable cooling; they also want sustainable equipment that features better energy efficiency and low-GWP solutions. Several compressor manufacturers have happily obliged.
