Title:
METHOD AND DEVICE FOR SETTING TARGET TEMPERATURE DIFFERENCE AT INLET AND OUTLET OF EVAPORATOR IN REFRIGERATOR AND REFRIGERATOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2016169891
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for setting a target temperature difference at an inlet and an outlet of an evaporator in a refrigerator which enables a target value to be set within a short period of time.SOLUTION: This invention relates to a method for setting a target value of a temperature difference between an inlet temperature 32 and an outlet temperature 33 of an evaporator 31 to manage an overheat degree of refrigerant after an evaporating process, at a refrigerant circuit performing the evaporating process within a range from an over-cooling region to an overheat region through circulation of the refrigerant by a refrigerant pump 21, comprising the steps of: circulating the refrigerant to the refrigerant circuit while increasing a circulating amount thereof stepwise, measuring the inlet temperature and the outlet temperature of the evaporator at the circulating amount of each step, calculating the temperature difference between the inlet temperature and the outlet temperature, and setting the target value on the basis of the temperature difference when a varying amount of the temperature difference between the steps becomes less than a prescribed threshold.SELECTED DRAWING: Figure 1
