Embodiment Construction

[0076] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other implementations obtained by those of ordinary skill in the art without creative work are within the scope of protection of this application.

[0077] In the related art, when the defrosting control is performed by setting the defrosting timing time, there are the following problems-for example, frequent defrosting is still carried out under the condition of no frost or slight frosting, which causes unnecessary defrosting actions. On the one hand, it causes energy waste, on the other hand, it reduces the heating effect of the air source heat pump system, which also reduces the comfort of the user experien...

Abstract

The invention relates to a defrosting control method and device and heating equipment and belongs to the technical field of defrosting control. The defrosting control method includes: acquiring outdoor fan currents during the heating operation of the heating equipment; determining whether to perform defrosting control on the heating equipment or not according to the outdoor fan currents; if so, performing defrosting control on the heating equipment. By the defrosting control method, unnecessary defrosting action can be reduced favorably, the problem that unnecessary energy waste and heating effect lowering caused by frequent defrosting when frost does not exists or slight frosting occurs is solved, heating effect increasing can be achieved, and user experience and comfortableness are improved.

Description

Technical field [0001] This application belongs to the technical field of defrosting control, and specifically relates to a defrosting control method, device and heating equipment. Background technique [0002] When the fin surface temperature of the outdoor fin heat exchanger of the air source heat pump is lower than the air dew point temperature and less than 0℃, the surface of the fin heat exchanger will be frosted, which increases the heat between the air and the fin heat exchanger At the same time, the frost layer increases the air flow resistance and reduces the air flow, thereby reducing the heat exchange of the fin heat exchanger. [0003] The frosting of air source heat pumps under low temperature and high humidity conditions is more serious, and timely defrosting is needed to improve the heating effect of the unit. At present, the most common defrosting control method is the time-temperature defrosting method, which works well under low temperature and high humidity. Ho...
