The CO2 by Wedholms system employs the CO2 byproduct from industrial processes.
Energy Recovery’s pressure-exchanger system can boost the COP of a transcritical CO2 system by an estimated 40-60% at an ambient temperature of 90°F (32°C), the company says.
The California company’s pressure-exchanger device is designed to significantly improve the efficiency of transcritical CO2 refrigeration systems in high-ambient-temperature locations.
Energy Recovery, Inc., a San Leandro, California (U.S.)-based manufacturer of pressure-exchanger devices, is “very close” to marketing a pressure exchanger designed to significantly improve the efficiency of transcritical CO2 (R744) refrigeration systems in high-ambient-temperature locations. The transcritical CO2 pressure exchanger device, model PX G1300, uses high-pressure gas from the gas cooler to boost the pressure…
