How It Works

Pressure exchangers recycle pressure energy from high-pressure CO2 to low-pressure CO2. Similar to a heat exchanger, which exchanges heat between two fluid streams, the pressure exchanger transfers pressure energy. Pressure exchangers can function as a compressor and high-pressure valve within a CO2 system to reduce compressor workload which increases cooling capacity, system stability, and energy efficiency.
