REFRIGERATOR AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To achieve satisfactory balance between required amount and amount of supply of refrigerant in an evaporation means of refrigerating cycle to prevent cooling efficiency from becoming worse due to occurrence of temporary shortage in refrigerant supply to an evaporator. SOLUTION: Operation and stop of a compressor 1 constituting refrigerating cycle Z1 are controlled based on the result of detection in a refrigerating chamber by a control part 20. Control for switching a cooling fan 6 for feeding air which is heat-exchanged with the evaporator 5 of refrigerant into the refrigerating chamber into a steady operation condition and an air blowing stop condition or an intermediate operation condition in which air capacity is smaller than that in the steady operation condition is performed when the compressor 1 is in an operation condition to suppress heat exchange with air in the evaporator 5 temporarily under the situation in which refrigerant supply to the evaporator 5 tends to be temporarily insufficient such as operation start time of the evaporator 5 and excessive load time in the refrigerating chamber.
