Problems solved by technology

However, when the outdoor temperature is extremely low, even if the compressor is not short-circuited, the control unit may mistakenly judge that the compressor is in a short-circuit state due to the low temperature of the refrigerant.

Abstract

This invention discloses a kind of air conditioner heating operation controlling method. It includes: indoor temperature detection step; outdoor temperature detection step; the first detection step for outdoor refrigerants pipe; compressor short time driving step; the second detection step for outdoor refrigerants pipe; when the temperature of outdoor refrigerants pipe is lower than the set temperature, heating operation of air conditioner is stopped. Error is displayed too. This invention can prevent air conditioner compressor from outputting error information and stopping operation under normal working state. Thus, it can increase trust degree the users towards air conditioner.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a method for controlling heating operation of the air conditioner. Background technique [0002] Generally, the split air conditioner consists of an indoor unit and an outdoor unit. The indoor unit is provided with an indoor fan and an indoor heat exchanger, while the outdoor unit is provided with a compressor, an outdoor heat exchanger, an expansion valve, a four-way valve and an outdoor fan, and the indoor unit and the outdoor unit are connected to each other through refrigerant pipes. Therefore, the air conditioner performs cooling operation or heating operation along the circulation direction of the refrigerant. In the case of heating operation, the refrigerant compressed by the compressor will flow through the four-way valve, indoor heat exchanger, expansion valve and condenser, and the refrigerant in the indoor heat exchanger will be condensed to dissipate heat to the room. Figure 4 ...
