Report Errors
The performance characteristics of coolant-source plate heat exchanger for heat pump system in electric vehicles was studied experimentally. In order to analyze plate heat exchanger with the coolant operating PE(Power Electronics) thermal management, coolant conditions was varied with respect to temperature, volume flow rate. Because the refrigerant in MAC(Mobile Air Conditioning) was about to be changed in our country, performance experiments were carried out for present(R-134a) and alternative(R-1234yf) refrigerants. With increasing coolant volume flow rate in plate heat exchanger, heat rejection rate increased due to refrigerant mass flow rate increment. While heating capacity of R-134a was increased by 78%, that of R-1234yf was increased by 67.5% due to lack of enthalpy difference in high pressure side. In case of coolant temperature, heating capacity with R-134a was decreased by 46.4% from 45℃to 53. 5℃. As a result, because changing refrigerant led to decrease performance, design modification is required to improve heat capacity. Modified plate heat exchanger as a condenser will be studied and plate heat exchanger as an evaporator will be executed experimentally under vehicle operating conditions.
