TEST DEVICE OF HEAT EXCHANGE FOR REFRIGERATOR

摘要

PURPOSE: A test device is to test the performance of a heat exchange using condensation of the coolant and the latent heat from vaporization in addition to the current heat exchange due to a temperature difference. CONSTITUTION: A test device a wind driving section provided with a simulating heat exchange for the performance test and insulated; a coolant controller for regulating the temperature and pressure of the coolant in order to meet the conditions at the inlet and outlet of the heat exchange; and coolant inlet and outlet allowing the coolant in and out between the coolant controller and the heat exchange. The coolant controller comprises a compression chamber alternately using at least two coolants to regulate the environmental temperature of the compressor; a condensation chamber for regulating the temperature and pressure for condensation; an overcooler for controller the overcooling; a preheater for supplying a heat of the inlet to the coolant in advance; a residual heater for supplying a heat of the outlet to the coolant in advance; and an absorber for controlling overheat.
