Embodiment Construction

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

[0035] figure 1 It is a structural schematic diagram of the air conditioner defrosting control device according to the present invention. Such as figure 1 As shown, the present invention provides an air conditioner defrost control device 10, the air conditioner includes an outdoor fan 220, wherein the air conditioner defrost control device 10 includes: a controller 11, used to perform the following steps: determine the air conditioner Whether the air conditioner enters the defrosting stage; and if the air conditioner enters the defrosting stage, control the reverse rotation of the outdoor fan 220 to perform convective heat exchange. In order to improve the he...

Abstract

The invention relates to the field of air conditioners, and discloses an air conditioner defrosting control device and a method. The air conditioner comprises an outdoor draft fan. The air conditioner defrosting control device comprises a controller for implementing the following steps: judging whether the air conditioner is in a defrosting phase; and controlling the outdoor draft fan to rotate reversely for exchanging the heat through convection if the air conditioner is in the defrosting phase. By the technical scheme, the defrosting speed of the outdoor heat exchanger is accelerated, accordingly increasing the using efficiency of the air conditioner, avoiding the uncomfortable feeling in the customer use, and increasing the defrosting degree, increasing the low temperature heating capacity, and thereby increasing the seasonal energy efficiency.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner defrosting control device and method. Background technique [0002] When the temperature is low, the user usually sets the air conditioner for heating to increase the indoor temperature, but as the air conditioner runs longer for heating, the condenser (outdoor heat exchanger) will be frosted , the longer the time, the thicker the frost will be. If defrost control is not adopted, it will seriously affect the heating effect of the air conditioner, thereby greatly reducing the heating capacity. The damage of the air conditioner brings economic loss to the user. [0003] The defrosting control of the air conditioner in the prior art requires a long defrosting time for the air conditioner with serious frosting, and the defrosting time exceeding 10 minutes will greatly reduce the use efficiency of the air conditioner and bring inconvenience to the user; The defros...
