Control method for non-stop defrosting of air conditioner and air conditioner

Abstract

The present invention relates to the technical field of air conditioning, and discloses a control method for non-stop defrosting of an air conditioner and the air conditioner, including: step S1, respectively setting the first defrosting temperature reference value and the second defrosting temperature of the defrosting temperature sensor reference value and the third defrosting temperature reference value; step S2, respectively set the first time reference value, the second time reference value and the third time reference value of the continuous cumulative operation of the outdoor unit; step S3, confirm that the first time reference value to the second time reference value, set the preset temperature of the defrosting temperature sensor as the first defrosting temperature reference value; Step S4, confirm that it is within the range from the first time reference value to the second time reference value , the actual temperature of the defrosting temperature sensor is lower than the first defrosting temperature reference value, and the heating component is activated to heat and defrost the inner coil of the outdoor unit. The control method has the advantage of not needing to switch the operating mode of the air conditioner, and can also perform defrosting when the air conditioner is in the heating mode.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner non-stop defrosting control method and the air conditioner. Background technique [0002] At present, during the heating process of the air conditioner, the four-way valve is in an open state, the outdoor heat exchanger is an evaporator, and the indoor heat exchanger is a condenser. Due to the low temperature of the evaporator and the outdoor environment The temperature is below zero. Therefore, there will be frosting in the water vapor or liquid water around the outdoor heat exchanger. After frosting, if the frosting is serious and cannot be defrosted in time and effectively, it will seriously affect the outdoor environment. The heat exchange performance of the air conditioner, that is, the outdoor unit cannot exchange heat normally, which eventually leads to a decrease in the heating capacity of the indoor unit, thereby affecting the heating effect o...

Problems solved by technology

[0005] The object of the present invention is to provide a control method for non-stop defrosting of an air conditioner and the air conditioner, so as to solve the problem that the defrosting method of the air conditioner in the prior art often needs to switch the air conditioner from the current heating mode when defrosting Switch to the cooling mode to let the refrigerant flowing through the outdoor heat exchanger dissipate heat and defrost. At this time, the indoor unit cannot heat, which is equivalent to being in the shutdown mode, which will reduce the comfort and experience of the user indoors. technical problem
