Abstract

The invention discloses an air conditioner and controlling method, which comprises the following steps: changing the opening value of electronic bulking valve before driving the second compressor according to rising condition of heating load; driving the second compressor under control order precisely. Therefore, the invention reduces the energy consumption due to fail driving of the second compressor, which improves the effect of convenience of the product.

Description

technical field [0001] The invention relates to an air conditioner and a control method thereof. In particular, when at least one compressor is used and the cooling and heating loads increase, the set opening value of the electronic expansion valve is changed, and the flow rate supplied to at least one compressor is adjusted, so that it can be stably driven and stopped. Air conditioner with at least one compressor and its control method {Air conditioner and the controlling method}. Background technique [0002] Fig. 1 is a schematic diagram showing a partial structure of a prior art air conditioner. [0003] As shown in Figure 1, based on cooling operation, the air conditioner in the prior art is composed of the following parts: a compressor 2 that compresses the refrigerant into a high-temperature and high-pressure gaseous refrigerant; condenses the refrigerant that passes through the compressor 2 into a medium-temperature and high-pressure The outdoor heat exchanger 4 of...
