Problems solved by technology

That is, when the air conditioner is in the overheating operation mode and the compressor, the outdoor unit fan, and the indoor unit fan are stopped, the actual indoor temperature (B) and the above-mentioned indoor temperature will be affected by the residual heat of the indoor heat exchanger. There is a large difference between the room temperature (A) detected by the sensor
Therefore, even if the above-mentioned actual indoor temperature (B) is lower than the desired indoor temperature, the air conditioner may remain in the overheating operation mode, which will reduce the efficiency of the air conditioner.

Abstract

A control method for heat pump type air conditioner includes such steps as defining the sum of desired indoor temp and predefined over-heating limit temp as the over-heating running temp, comparing it with indoor temp, judging if the air conditioner is running in over-heating mode, and driving the fan of indoor set if it is.

Description

technical field [0001] The invention relates to a control method of a heat pump air conditioner. More specifically, the present invention relates to: when the air conditioner is in the overheating operation mode, and the compressor is in the stopped state, in order to remove the residual heat of the indoor heat exchanger, the fan of the indoor unit is driven, so that the overheating can be shortened to the greatest extent. A method for controlling the heating operation time of a heat pump air conditioner. Background technique [0002] Figure 8 It is a graph showing the indoor temperature, indoor piping temperature, indoor unit fan, and expansion device status with respect to the heating operation time of the conventional heat pump air conditioner. [0003] Such as Figure 8 As shown, the method of controlling the overheating of the conventional heat pump air conditioner will be described as follows. [0004] When the air conditioner is operating in the heating operation m...
