Embodiment Construction

[0037] 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.

[0038] In this example, in order to improve the accuracy of detecting the frosting condition, especially in the case of low-temperature heating, the frosting condition can be detected more accurately, and the unit enters defrosting, so as to improve the performance of the unit and reduce power consumption, Improve user experience.

[0039] The inventor considers that when the ambient temperature is low, the defrosting temperature cannot accurately reflect the frosting condition of the unit. Therefore, a judgment condition can be added: the difference between the ambient temperature and the defr...

Abstract

The invention provides a defrosting control method and device. The method includes the steps that whether the environment temperature is lower than the preset temperature threshold value or not is confirmed, and if the environment temperature is lower than the preset temperature threshold value, the defrosting temperature of a unit is obtained; whether the difference value between the environment temperature and the defrosting temperature is larger than the preset defrosting temperature difference or not is judged; and if the difference value is larger than the preset defrosting temperature, the unit is controlled to enter in the defrosting operation. The defrosting control method solves the problem that at present, whether the defrosting operation is executed or not is judged simply according to the defrosting temperature, and consequently the defrosting executing time is not accurate, and the defrosting efficiency is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning control, in particular to a defrosting control method and device. Background technique [0002] At present, the defrosting of the unit is mainly based on the continuous heating operation time of the unit, the defrosting interval, the defrosting temperature and other conditions to periodically defrost the unit. Although this defrosting control method can also solve the problem of unit frosting, it is relatively Relatively simple machine. [0003] Especially when the ambient temperature is relatively low, the frosting condition of the unit cannot be accurately judged only based on the defrosting temperature, which may easily lead to the problem that the defrosting cannot be done in time or enter the defrosting in advance, which will cause waste of power consumption and affect the user experience. [0004] Aiming at the above problems, no effective solution has been proposed yet. ...
