Embodiment Construction

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The main core idea of ​​the present invention is to control the heat exchange area of ​​the heat exchanger according to the change of the cooling (heat) amount during the operation of the air conditioner, so that the heat exchange area of ​​the heat exchanger matches the cooling (heat) amount of the air conditioner, thereby Improve the efficiency of the heat exchanger.

[0036] Such as figure 1 As shown, the air conditioner based on the present invention may include a compressor 10, a four-way valve 20, an indoor heat exchanger 30 and an outdoor heat exchanger 40, and the compressor 10, the four-way valve 20, the indoor heat exchanger 30 and the The outdoor h...

Abstract

The invention discloses an air conditioner control method. The air conditioner control method comprises the following steps: flow of a refrigerant about to enter an indoor heat exchanger and / or an outdoor heat exchanger during operation of an air conditioner is acquired; the acquired flow of the refrigerant is compared with a preset flow level, and the flow level corresponding to the acquired flow of the refrigerant is acquired; the heat exchange area of the indoor heat exchanger and / or the outdoor heat exchanger is adjusted according to the flow level corresponding to the acquired flow of the refrigerant, so that the heat exchange area of the indoor heat exchanger and / or the outdoor heat exchanger is matched with the flow of the refrigerant. The invention further provides an air conditioner control device. With adoption of the air conditioner control method and device, not only are the requirements of the indoor heat exchanger for heat exchange met, but also sufficient use of the indoor heat exchanger is guaranteed, the heat exchange efficiency of the indoor heat exchanger is improved, and energy saving performance of the air conditioner is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner control method and device. Background technique [0002] Inverter air conditioners change the power supply frequency of the compressor, adjust the compressor speed, and then adjust the cooling (heat) capacity of the air conditioner to achieve the purpose of controlling the room temperature. When the power supply frequency is high, the cooling (heat) capacity of the air conditioner is large; when the power supply frequency is low, the cooling (heat) capacity of the air conditioner is small. The size change of the above-mentioned refrigeration (heat) amount must be adjusted by the electronic expansion valve in the air conditioner. However, during the adjustment process, the heat exchanger cannot automatically adjust the heat exchange area. When the air conditioner is running at low frequency, the heat exchange area of ​​the heat exchanger is too large, which will...
