TEMPERATURE CONTROLLER OF COLD STORAGE BOX

摘要

PURPOSE:To provide a cold storage box temperature controller that detects an increase of an indoor load to a refrigerating chamber and correcting the temperature of control for the refrigerating chamber based on the value of the increase and the ambient temperature and, at the same time, controlling the actions of a blower and compressor by the corrected temperature of control. CONSTITUTION:The objective temperature controller is provided with a temperature determination section 58 that corrects a set temperature of the refrigerating chamber based on auxiliary temperature TS that is detected by an auxiliary temperature sensor 52 and outdoor temperature TB detected by an outdoor temperature sensor 56 and determines control temperature TK and a control signal output section 59 that outputs control signal to control the actions of the compressor motor 61 and blower motor 62 based on the control temperature TK and the main temperature TM of the refrigerating chamber that is detected by a main temperature sensor 51.
