Research of heat–and–power engineering characteristic changes of freezing box evaporator under the work of household refrigerator DH–239

Abstract

By means of thermographic shooting experimental studies of distribution of temperature on a surface of the evaporator of the household DH–239 refrigerating appliance working at isobutane depending on a dose of filling of refrigerating system are carried out. The received results can be used for definition of the possible location of the sensor of the device signaling about emergency work of HHR.
