Experimental Study of a Trans-Critical CO2 Mobile Air Conditioning System with an Ejector

A carbon dioxide(CO2) ejector expansion air conditioning system for vehicles is developed in a calorimeter laboratory. In experimental tests on a standard mobile air conditioning bench, the effects of different operating parameters on the performance of the CO2 refrigeration system for vehicles are...
