Problems solved by technology

[0003] At present, the defrosting frequency of automatic defrosting of conventional inverter air conditioners is based on the set frequency value, and defrosting is carried out at a relatively fixed rate of increase (usually 1Hz / s). The problem with this defrosting method is that defrosting The time is relatively long, and in some areas that require high comfort, the longer the defrosting time, the greater the impact on the indoor heating effect

Embodiment Construction

[0017] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings. The purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solutions of the present invention. and contribute to its implementation.

[0018] In order to solve the problems existing in the prior art and overcome its defects, and shorten the defrosting time of the air conditioner, the technical scheme adopted by the present invention is:

[0019] The defrosting control method of the air conditioner of the present invention includes controlling the defrosting frequency of the compressor to rise at different rates according to different outdoor temperatures T4. Compared with the compressor defrosting frequency rising at a fixed rate when the air conditioner is defrosting, the compressor defrosting frequency can be selected...

Abstract

The invention discloses a defrosting control method of an air conditioner. The method includes the step of controlling defrosting frequency of a compressor according to different outdoor temperatures T4 to ascend according to different rates. The defrosting control method has the advantages that the different defrosting frequency ascending rates are selected according to the different outdoor temperatures, the final defrosting time is shorter than the defrosting time of the fixed rate, the defrosting time is shortened, and consequently the indoor comfort is improved.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to a method for controlling defrosting of an air conditioner. Background technique [0002] During the heating cycle of the air conditioner, the refrigerant in the indoor heat exchanger is in a state of high temperature and high pressure, and the refrigerant in the outdoor heat exchanger is in a state of low temperature and low pressure, which needs to absorb external heat to complete evaporation. When the outdoor temperature is low, the temperature of the outdoor heat exchanger is usually low. After a period of operation, the outdoor heat exchanger will frost, and the temperature of the outdoor heat exchanger will become lower and lower after frosting, which seriously affects the indoor environment Heating effect. Therefore, it is necessary to defrost the outdoor heat exchanger every once in a while. [0003] At present, the defrosting frequency of automatic defrosting...
