ATS Japan is taking advantage by providing the semiconductor industry with the first chillers that use CO2 (R744) as a refrigerant. The GX Series high performance green chillers use CO2 and work within a broad operating range (-20C to +70C). ATS manufactures standard and custom engineered products to provide customers with the right solution.
The SNAP proposal lists HFO-1234yf, HFC-32 and HFO blends as acceptable for new chiller equipment.
Dorin has carried out a comparison of process-cooling chillers with a number of refrigerants, concluding that new technologies make CO2 efficient even in warm U.S. climates.
The EESC Committee is also in favor of setting a 150 GWP cap across all technologies and promoting incentives schemes and public procurement for f-gas-free alternatives.
VanderGiessen will discuss Pro Refrigeration’s experience manufacturing CO2 chillers for industrial applications on July 21 at 5pm CEST (11am EDT).
Customized system uses R290-chilled glycol to keep the CO2 in subcritical mode.
ATS Japan is enjoying growing sales of its CO2 units, with production soon of two new models.
For every chiller application, there is a natural refrigerant solution available, says Teko Managing Director, Andreas Meier.
New Grundfos units use temperature sensors to regulate water flow.
The U.S. Environmental Protection Agency has published in the Federal Register a notice finding carbon dioxide acceptable as a refrigerant in new equipment for ice skating rinks, centrifugal chillers, positive displacement chillers and industrial process air conditioning.
