Lower-GWP alternatives to refrigerant R410a for air-cooled chillers
Customers are increasingly moving towards air conditioning and refrigeration equipment running on lower-GWP alternatives than currently widely used refrigerant R410a.
The current restrictions, such as Europe’s F-Gas regulations, have started the phase-down of HFCs, including R410a, to slow global warming and reduce direct carbon emissions. With the start of HFCs phase-down, prices and availability of these refrigerants were significantly affected and led to a growing demand for lower-GWP alternatives.
Kaltra intends to adopt R515b for its water chillers
The development of environmentally friendly refrigerants for air conditioning and refrigeration equipment is imperative to the growth of HVAC technology. The low-GWP refrigerants like R1234ze are promising candidates for replacing HFC refrigerants. However, these refrigerants are flammable. To address the flammability issue, Honeywell developed Solstice® N15, a non-flammable HFO blend.

New chillers for Arla dairy processing plant
Processing of milk products requires the correctly designed process in order to attain end products of the highest quality. Processing of milk involves pasteurization, a technique that destroys pathogens in milk and makes it safe to drink. Pasteurization necessitates the use of chilled water to cool down the milk after the heating-up process to prevent the deterioration. During the cooling process, the pasteurized milk has to be cooled to 0°C. Thus, the production of chilled water for dairy processing operations is a vital part of producing safe and high-quality consumer products. Tight thermal control is also a crucial requirement for dairy processing facilities.
