Abstract

An apparatus for controlling operation of an air conditioner having a compressor for compressing refrigerant and a heat exchanger for heat-exchanging refrigerant with ambient air, includes a temperature sensor installed on a passage through which refrigerant passes, for detecting a temperature of refrigerant; and a control unit connected to the temperature sensor, for controlling the operation of the compressor in response to the temperature detected by the temperature sensor. Accordingly, an overload of the compressor is determined on the basis of a temperature of refrigerant, which is detected by the temperature sensor, so that an effective compressor overload response can be made.

Description

technical field [0001] The present invention relates to an air conditioner, and more particularly to a device for controlling the operation of the air conditioner, which is capable of effectively responding to compressor overload. Background technique [0002] In general, an air conditioner is a device that maintains an appropriate indoor temperature by utilizing latent heat of evaporation of a refrigerant. The refrigerant circulates in the refrigeration cycle of the compressor, heat exchanger, expansion valve, and evaporator. [0003] The air conditioner performs the cooling operation on the room through a series of processes. The compressor compresses the refrigerant to the saturation pressure, and the compressed refrigerant is liquefied through the heat exchanger. Through the throttling of the expansion valve, the liquefied refrigerant is reduced. In an expanded state, it is introduced into the evaporator, and while evaporating in the evaporator, the introduced refrigera...
