Embodiment Construction

[0025] 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.

[0026] The invention provides a defrosting control method of an air conditioner, figure 1 It is a flow chart of the air conditioner defrosting control method according to the present invention, as figure 1 As shown, the method includes the following steps:

[0027] S1. The air conditioner runs in the heating mode and detects the tube temperature after the initial frost control time A0. A0 is preferably 40 minutes. If the tube temperature condition for defrosting is met, it will enter the first defrosting operation mode and record the actual value of this cycle. Defrost time T1; (T1 is the time when the actual air conditioner sends the signal to enter the defrost operation mode minus the time when the air conditioner sends the signal to ex...

Abstract

The invention provides a defrosting control method for an air conditioner. The defrosting control method for the air conditioner comprises the steps that after the air conditioner operates in a defrosting mode, the actual defrosting time of the air conditioner in the current cycle is acquired; a proportionality coefficient K is calculated according to the difference between the actual defrosting time and a standard defrosting time, and the defrosting control time of the air conditioner operating in the defrosting mode in the current cycle is acquired; and the defrosting control time of the airconditioner operating in the defrosting mode in the next cycle is calculated according to the proportionality coefficient and the defrosting control time of the current cycle. According to the defrosting method for the air conditioner, the proportionality coefficient is calculated according to the difference between the actual defrosting time in the current cycle and the standard defrosting time,and a proper time variable is obtained through the proportionality coefficient to correct the defrosting control time of the air conditioner operating in the next cycle, so that the operability of the method is high, the universality is good, the defrosting operation time is made reasonable finally, the actual defrosting time of each cycle is made to close to the standard defrosting time (namelythe frosting thickness is consistent), and the comfort of users is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling defrosting of an air conditioner. Background technique [0002] When the air conditioner is heating at low temperature, frost often occurs on the coil of the condenser, and the frost will affect the heating effect of the air conditioner. At this time, it is necessary to enter the defrosting mode to defrost. The defrosting control methods in the prior art basically judge whether defrosting needs to be performed by satisfying the operating time condition and the condenser coil temperature condition simultaneously, and the operating time condition is usually fixed. However, the defrosting control method in the prior art still has the following problems: under high-humidity conditions, the condenser coil frosts quickly, and it often happens that the tube temperature has already met the defrosting conditions, but the time has not reached the set time,...
