Problems solved by technology

[0003] For the air conditioner, in the heating mode, it is often necessary to defrost, but it is often impossible to heat normally during defrosting. If the speed of frosting can be effectively reduced, the continuous heating time of the air conditioner can be effectively improved. , improve people's comfort
[0004] For how to effectively reduce the speed of frost formation, no effective solution has been proposed so far

Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0047] Considering that for air conditioners, when heating in an unsteady state, there will be capacity attenuation. When the heating capacity attenuates to a certain extent, in order to ensure the heating capacity, it is often necessary to defrost, and defrosting will not be able to perform heating. If the heating capacity decays too fast, or the defrosting frequency is too high, it will affect the user experience.

[0048] Based on this, a frosting control method is provided in this example, such as figure 1 As shown, the following steps may be included:

[0049] Step 101: Obtain the ambien...

Abstract

The invention provides a frosting control method and device. The method includes the steps that the outdoor unit environment temperature of an air conditioner and the defrosting temperature of the air conditioner are obtained; and the opening degree of an electronic expansion valve is helped to be controlled according to the difference value between the outdoor unit environment temperature and the defrosting temperature. By means of the above manner, the problem that the evaporation temperature and the pressure are too low during heating of an existing air conditioner system, and consequently the surface of an outdoor unit heat exchanger is frosted is solved; and the technical effects that the heating capability keeps not attenuated or little attenuated for a long time, the defrosting times are reduced, and the heating time is prolonged are achieved.

Description

technical field [0001] The present invention relates to the technical field of equipment control, in particular to a frosting control method and device. Background technique [0002] With the development of technology and the improvement of people's living standards, the use of air conditioners is becoming more and more widespread, whether in offices or at home, air conditioners are very common. [0003] For the air conditioner, in the heating mode, it is often necessary to defrost, but it is often impossible to heat normally during defrosting. If the speed of frosting can be effectively reduced, the continuous heating time of the air conditioner can be effectively improved. , improve people's comfort. [0004] For how to effectively reduce the speed of frost formation, no effective solution has been proposed yet. Contents of the invention [0005] An embodiment of the present invention provides a frosting control method to achieve the purpose of maintaining the heating ...
