Embodiment Construction
[0034] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the technical solution of the present disclosure will be clearly and completely described below in conjunction with specific embodiments of the present disclosure and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present disclosure, but not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.
[0035] to combine Figure 1 to Figure 2 As shown, this embodiment provides a self-cleaning control method for the self-cleaning of the indoor heat exchanger 2 of the cooling-only air conditioner. The cooling-only air conditioner includes a compressor 1, an indoor heat exchanger 2, and an outdoor heat exchanger 3. A first electronic expansion valve 4 is prov...

The invention provides a self-cleaning control method and a single-cooling type air conditioner. In a condensation stage, a compressor operates to enable a surface temperature of an indoor heat exchanger to be lower than an air dew point temperature; in a frosting stage, the compressor operates to enable the surface temperature of the indoor heat exchanger to be lower than 0 DEG C; and in a defrosting and drying stage, a second electronic expansion valve is controlled to be in an all-open state, and a first electronic expansion valve is controlled to be in a throttling working state; and self-cleaning is completed. According to the self-cleaning control method, in the self-cleaning defrosting stage, the opening degrees of the electronic expansion valves are maximum, a high-temperature refrigerant discharged by the compressor is cooled in an outdoor heat exchanger and then flows to the indoor heat exchanger at a high temperature, frost on the indoor heat exchanger is heated and melted, and the indoor heat exchanger is dried after defrosting is completed, so that sterilization and dust removal effects are achieved.
Description
technical field [0001] The disclosure belongs to the technical field of air conditioning, and in particular relates to a self-cleaning control method for a cooling-only air conditioner and a cooling-only air conditioner. Background technique [0002] Cold-only air conditioners refer to air conditioners that only have a cooling function, and are generally used in summer. Corresponding to it is the heating and cooling air conditioner. The cooling-only air conditioners do not have the self-cleaning function of the evaporator, so it is difficult to meet the growing health needs of users. Contents of the invention [0003] Therefore, the technical problem to be solved in the present disclosure is that no cooling-only air conditioner has a self-cleaning function, so as to provide a self-cleaning control method and a cooling-only air conditioner. [0004] In order to solve the above problems, the present disclosure provides a self-cleaning control method for self-cleaning of th...
