Problems solved by technology

[0005] The existing defrosting method needs to switch the hydrogen desorption / absorption status of the outdoor unit heat exchanger and the indoor unit heat exchanger at the same time. During the switching process, the outdoor unit heat exchanger and the indoor unit heat exchanger need to be controlled synchronously, increasing power consumption of the air conditioner

Abstract

The invention relates to the technical field of air conditioners, and discloses a defrosting control method for an air conditioner. The air conditioner comprises an electrochemical compressor and a first heat exchanger which communicates with the electrochemical compressor through a hydrogen release channel and is installed in the outdoor environment. The method comprises the steps that the frosting state of the first heat exchanger is obtained; and if it is determined that the first heat exchanger is in the frosting state, the hydrogen flow of the hydrogen release channel communicating with the electrochemical compressor is reduced. By means of the method, the power consumption of the air conditioner can be reduced. The invention further discloses a defrosting control device for the air conditioner and the air conditioner.

Description

technical field [0001] The present application relates to the technical field of air conditioners, for example, to a defrosting control method and device for an air conditioner, and an air conditioner. Background technique [0002] At present, electrochemical compressor technology is gradually applied to the field of air conditioning. The working principle of the electrochemical compressor is to operate by pumping protons through the ion exchange membrane between two gas diffusion electrodes. These protons will drive the non-fluorine refrigerant through the ion exchange membrane; After one side, the high pressure will be released and enter the refrigeration cycle system. Most of the air conditioners using electrochemical compressors use hydrogen as the cooling medium, and fill metal hydrides into the heat exchanger. During the process of hydrogen or dehydrogenation, the temperature of the air passing through is raised or lowered to achieve heating or cooling. [0003] Whe...
