APPARATUS EVALUATING EVAPORATOR PERFORMANCE FOR CO2 AIR CONDITIONER SYSTEM FOR VEHICLE

摘要

An apparatus of evaluating performance of an evaporator of a CO2 air conditioning system for a vehicle is provided to effectively evaluate cooling performance of the evaporator at a low flow rate of wind by bypassing a part of refrigerant introduced into a test evaporator through an auxiliary evaporator. An apparatus of evaluating performance of an evaporator of a CO2 air conditioning system for a vehicle comprises a chamber(110) having a wind tunnel(111) on which a test evaporator(112) is installed. A compressor(121), a first heater(122), a first intercooler(123) are formed at an outer side of the chamber. A second heater(113), an expansion valve(114) and a second intercooler(124) are formed in the chamber. Refrigerant discharged from the first heater exchanges heat with refrigerant introduced to the compressor by an inter heat exchanger(115). An accumulator(116) divides refrigerant introduced to the compressor into gaseous refrigerant and liquefied refrigerant.
