Embodiment Construction

[0051] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] When the air conditioner is running for heating, the outdoor heat exchanger absorbs the heat from the outdoor environment and transfers it to the room to increase the indoor temperature. However, the outdoor heat exchanger acts as an evaporator at this time. When the temperature is lower than the air dew point, it will cause frost on the outdoor heat exchanger, which will affect the heating effect and bring inconvenience to the user.

[0053] In view of the phenomenon of frosting on the outdoor heat exchanger of the air conditioner, the existing technology takes the following steps to defrost: After receiving the external defrosting command, after waiting for a period of time, control the indoor fan to stop, and after waiting for a p...

Abstract

The invention provides an air conditioner defrosting control method and device, an air conditioner and a storage medium, and relates to the technical field of air conditioners. The air conditioner defrosting control method comprises the following steps of: obtaining the inner ring temperature of the air conditioner when receiving a defrosting instruction; judging whether preset special defrostingconditions are met or not according to the inner ring temperature; and controlling the air conditioner to perform a special defrosting operation if the preset special defrosting conditions are met, soas to shorten the time for defrosting by absorbing heat from the indoor side of the air conditioner. The invention aims to perform the special defrosting operation according to the temperature of theinner ring, so that the air conditioner absorbs heat from the indoor side during defrosting, and uses the heat absorbed from the indoor side to defrost, thereby achieving the effect of shortening thedefrosting time, improving the defrosting efficiency, and promoting the air conditioner to maintain effective heating operation, which is convenient for users to use.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method and device, an air conditioner and a storage medium. Background technique [0002] During heating operation in winter, the outdoor heat exchanger exchanges heat with the external environment, absorbs the heat from the outdoor environment and transfers it to the room, so as to increase the indoor temperature. However, when the surface temperature of the outdoor heat exchanger is lower than the air dew point temperature , It will cause frost on the outdoor heat exchanger, affect the heating effect, and bring inconvenience to the user. [0003] Aiming at the phenomenon of frosting on the outdoor heat exchanger of the air conditioner, the existing technology adopts the following method to defrost: when the defrosting conditions are met, wait for a period of time, control the indoor fan to stop, and then control the outdoor...
