Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the air conditioner cannot effectively defrost due to the inaccurate judgment of the frosting thickness of the outdoor heat exchanger in the existing defrosting method, the present invention provides a The defrosting control method for an air conditioner includes an outdoor heat exchanger. The defrosting control method includes the following steps: when the air conditioner is running in a heating mode, obtain the surface temperature of the outdoor heat exchanger; obtain the temperature of the outdoor heat exchanger The moisture content of the incoming air and the moisture content of the outgoing air; determine the frosting thickness of the outdoor heat exchanger based on the moisture content of the incoming air and the outgoing air; judge whether to use the air conditioner according to the surface temperature and frosting thickness defrost mode

Abstract

The invention relates to the technical field of air conditioners, in particular to a defrosting control method for an air conditioner. The method aims to solve the problem that in an existing defrosting mode, the judgment of the frosting thickness of an outdoor heat exchanger is not accurate and accordingly an air conditioner cannot be effectively defrosted. Therefore, the air conditioner comprises an outdoor heat exchanger. The defrosting control method comprises the following steps that under the condition that the air conditioner runs in a heating mode, the surface temperature of the outdoor heat exchanger is obtained; the air inlet moisture content and the air outlet moisture content of the outdoor heat exchanger are obtained; the frosting thickness of the outdoor heat exchanger is determined on the basis of the air inlet moisture content and the air outlet moisture content; whether the air conditioner enters a defrosting mode or not is judged according to the surface temperature and the frosting thickness. The frosting thickness of the outdoor heat exchanger is determined on the basis of the air inlet moisture content and the air outlet moisture content, and whether the outdoor heat exchanger needs to be defrosted or not is judged according to the surface temperature of the outdoor heat exchanger so that whether the air conditioner enters the defrosting mode or not can bejudged accurately.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and specifically provides a defrosting control method for an air conditioner. Background technique [0002] As a device that can adjust the indoor ambient temperature, the air conditioner works on the principle that the indoor ambient temperature is reduced or increased by the refrigerant passing through the circulation pipeline through high-pressure / low-pressure / gas / liquid state transitions, that is, from From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. In the heating mode, the outer coil of the outdoor unit (evaporator) of the air conditioner is prone to frost, and the frost on the outer coil will cause the performance of the refrigeration system to decline, thereby affecting the heating effect of the air conditioner and reducing the indoor environment. comfort and affect user experience. Therefore, when the air conditioner is in a heating c...
