WEST LAFAYETTE, IN — One area in which CO2 is getting an early wave of attention is mobile A/C and transport refrigeration. Researchers from the Thermodynamic Institute in Germany looked at compressors that might work in such applications.
They studied a pressure-controlled reciprocating compressor, a pressure-controlled swash-plate compressor, and a path-controlled swash-plate compressor. Prototype compressors “were tested on a test rig under conditions expected in air conditioning, refrigeration, and heat pump applications.”
