Cleaning method and device for evaporator of cooling-only air conditioner

Abstract

The invention discloses a cleaning method for an evaporator of a cooling-only air conditioner. The cleaning method includes the steps that the cooling-only air conditioner enters the evaporator self-cleaning mode, and a compressor and an outdoor draught fan are started for refrigeration; if the surface temperature t of an indoor heat exchanger is lower than the preset temperature t1, the surface of the evaporator frosts; in the frosting process, when the surface temperature t of the indoor heat exchanger is lower than the preset temperature t2, the compressor and the outdoor draught fan are stopped, an indoor draught fan is started for defrosting, the evaporator is cleaned through water generated after defrosting, and the preset temperature t2 is lower than the preset temperature t1. The invention further discloses a cleaning device for the evaporator of the cooling-only air conditioner. By means of the cleaning method and the cleaning device, automatic cleaning of the evaporator of the cooling-only air conditioner is achieved, it is avoided that because too much matter such as dust is accumulated in the evaporator, health of users is influenced, the accessory loss of the cooling-only air conditioner during operation is also reduced, and the energy consumption is lowered.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cleaning method and device for an evaporator of a single cooler. Background technique [0002] During the operation of the single-cooler, due to the gaps and spaces such as the heat dissipation holes of the single-cooler itself, the evaporator is easy to accumulate dust and other dirt. If there is too much dust and other substances accumulated on the evaporator and related accessories, it will affect The operating efficiency of related accessories, furthermore, during long-term low-efficiency operation, it is easy to cause loss to related accessories and consume a lot of energy; [0003] In the current operating mode of the single-cooler, there is no relevant technical solution for cleaning the evaporator. If the evaporator is to be cleaned, professional cleaning personnel must disassemble the single-cooler and manually clean the evaporator and related accessories, whi...

Problems solved by technology

[0002] During the operation of the single-cooler, due to the gaps and spaces such as the heat dissipation holes of the single-cooler itself, the evaporator is easy to accumulate dust and other dirt. If there is too much dust and other substances accumulated on the evaporator and related accessories, it will affect The operating efficiency of related accessories, furthermore, during long-term low-efficiency operation, it is easy to cause loss to related accessories and consume a lot of energy;

[0003] In the current operating mode of the single-cooler, there is no relevant technical solution for cleaning the evaporator. If the evaporator is to be cleaned, professional cleaning personnel must disassemble the single-cooler and manually clean the evaporator and related accessories, which is labor-intensive and expensive.
