Title:
REFRIGERATION UNIT
Document Type and Number:
Japanese Patent JP2019086199
Kind Code:
A
Abstract:
To improve the refrigeration unit efficiency by making the heat exchange between the cold storage material and the air temperature possible even in the temperature range where the efficiency of heat exchange is bad by temperature slip, the coolant temperature is increased so that the temperature of the heat exchanger comes close to the air temperature.SOLUTION: A refrigeration unit comprising refrigeration cycle filled with refrigerant having temperature slip, comprises: a coolant passage layer in which coolant passes through between an evaporator 24 and a compressor 21; a cold storage part 30 having a cold storage layer with a cold storage material chamber that can be filled with a cold storage material, and an air passage layer through which outside air passes; a pressure detector for detecting the delivery pressure of the compressor 21; a temperature detector for detecting an air temperature; a filling amount control part for determining the filling amount of the cold storage material in the cold storage material chamber on the basis of the detected delivery pressure and the air temperature; and a filling mechanism 35 for adjusting the filling amount of the cold storage material in the cold storage material chamber into which the cold storage material is stored by a signal from the filling amount control part.SELECTED DRAWING: Figure 1
