Problems solved by technology

[0003] However, before defrosting is required, it is often the period when the frost layer deteriorates and the capacity decays seriously. During this period, increasing the heating capacity will not only make the frost layer worse, but also increase the time of subsequent defrosting and increase the indoor temperature drop before and after defrosting. , will also cause a waste of energy, and at the same time fail to meet the needs of comfort
[0004] For the above problems, no effective solution has been proposed

Abstract

The invention discloses a defrosting control method and device, a storage medium and a processor. Wherein, the method includes: obtaining the indoor ambient temperature, the indoor set temperature, the intermediate temperature of the outdoor heat exchanger, and the running time of the target device; calculating the first difference between the indoor set temperature and the indoor ambient temperature; The first difference is compared with the first preset temperature to obtain a first comparison result, the intermediate temperature of the outdoor heat exchanger is compared with the second preset temperature to obtain a second comparison result, and the operating time Comparing with the first time threshold to obtain a third comparison result; according to the first comparison result, the second comparison result and the third comparison result, control the target device to defrost or stop at a temperature point. The invention solves the technical problem of increasing the subsequent defrosting time caused by increasing the heating capacity of the air conditioner before defrosting is required in the related art.

Description

technical field [0001] The present invention relates to the field of defrosting control, in particular to a defrosting control method and device, a storage medium, and a processor. Background technique [0002] The defrosting control method of the existing air conditioner is to increase the heating capacity of the air conditioner before defrosting is required to increase the indoor temperature, so as to achieve the purpose of making the indoor temperature and the set temperature reach the preset temperature during defrosting. [0003] However, before defrosting is required, it is often the period when the frost layer deteriorates and the capacity decays seriously. During this period, increasing the heating capacity will not only make the frost layer worse, but also increase the time of subsequent defrosting and increase the indoor temperature drop before and after defrosting. , also can cause the waste of energy, also can't meet the demand of comfort simultaneously. [0004...
