ATMO Europe – Pressure Exchanger Found to Boost COP of CO2 Refrigeration by 25% at High Ambient Temperatures

ATMO Europe 2022 - Joseph Marchetti - Energy Recovery

Energy Recovery, a California-based manufacturer of pressure exchangers, has found that its PX G1300 device can increase the energy efficiency of CO2 (R744)-based commercial refrigeration systems by up to 25% at an ambient temperature of around 37°C (98.6°F), compared to a standard CO2 booster system.

In so doing, the pressure exchanger can also help lower capital expenditure and operational costs by reducing the load on a system’s compressor, according to Joseph Marchetti, Energy Recovery’s Product Manager for CO2 Refrigeration.

Data was gathered from an installation at a European supermarket, and the results were presented by Marchetti during a refrigeration session at the ATMOsphere (ATMO) Europe Summit on natural refrigerants. The conference took place November 15–16 in Brussels and was organized by ATMOsphere, publisher of
