Abstract

PURPOSE: To provide a defrosting controller capable of ensuring the operation thereof by a method wherein defrosting operation is controlled by a set temperature memorizing means, which stores a set temperature switched in accordance with the frequency of an electric source, and the difference of temperatures detected by two sets of temperature detecting means.
CONSTITUTION: The capacity of a compressor 1 is different with frequency of an electric source 50Hz or 60Hz while the pressure and the delivery temperature of an outdoor heat exchanger 5 upon frosting are different in case the frequency of the electric source is different. The inlet pipeline temperature (t) of an indoor heat exchanger 3 is also different generally under 50Hz or 60Hz, therefore, the judgement of defrosting is effected by switching the set pipeline temperature (t1) under 50Hz or 60Hz. The inlet pipeline temperature (t1) of the indoor heat exchanger 3 is the temperature of refrigerant gas in an overheating area, therefore, it is hardly affected by the flow amount of a fan 7 while the central part pipeline temperature (t2) of the heat exchanger 3 detects a condensing temperature, therefore, it is stable accordingly, the judgement of defrosting operation may be effected properly under 50Hz or 60Hz by measuring a temperature difference (t1-t2).
