Problems solved by technology
[0005] In order to solve the above-mentioned problem in the prior art, that is, the existing air conditioner cannot accurately judge the timing of executing the defrosting mode, which results in false defrosting, the present invention provides a defrosting control method for the air conditioner. The air conditioner includes an indoor unit and an outdoor unit, the outdoor unit includes an outdoor unit coil, and the method includes: when the air conditioner is in a heating condition, acquiring the ambient temperature at the location of the outdoor unit; acquiring the outdoor temperature The temperature of the machine coil and the air outlet temperature of the indoor unit; according to the ambient temperature, the coil temperature of the external unit and the air outlet temperature of the indoor unit, the air conditioner is selectively entered into the defrosting mode

The invention relates to the technical field of air conditioners, in particular to an air conditioner and a defrosting control method thereof. According to the air conditioner and the defrosting control method thereof, the air conditioner comprises an outdoor unit and an indoor unit. The outdoor unit comprises an outdoor unit coil pipe. The method includes the steps that under the condition that the air conditioner is in a heating working condition, the environment temperature of the position where the outdoor unit of the air conditioner is located is acquired; the temperature of the outdoor unit coil pipe and the outlet air temperature of the indoor unit are acquired; and the air conditioner selectively gets into a defrosting mode according to the environment temperature, the temperatureof the outdoor unit coil pipe and the outlet air temperature of the indoor unit. By means of the defrosting control method, the environment temperature, the temperature of the outdoor unit coil pipe and the outlet air temperature of the indoor unit are comprehensively judged, and therefore the time when the air conditioner gets into the defrosting mode can be accurately judged.
Description
Technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a defrosting control method thereof. Background technique [0002] Air conditioning systems have been widely used in large buildings, such as hospitals, large shopping malls, office buildings, and hotels. When the air conditioner is in heating mode, the surface temperature of the outer coil of the air conditioner is lower than the ambient temperature, and frost will appear on the surface of the outer coil when it is below zero. The frosting of the external coil will cause the overall performance of the air conditioner to decrease, thereby affecting the heating effect of the air conditioner, reducing the comfort of the indoor environment, and then affecting the user experience. Therefore, when the air conditioner is in heating mode, it is necessary to perform timely and effective defrosting operation on the external coil of the air conditioner. [0003] ...
