Problems solved by technology

Because the heat exchangers at both ends of the current electrochemical compression device change from extremely hot to extremely cold, or from extremely cold to extremely hot during the periodic cooling and heating switching process, which will reduce the service life of the electrochemical compressor. And to a certain extent, periodic refrigeration or heating instability occurs, which reduces the comfort and stability of the air conditioning system

Abstract

The invention discloses an electrochemical air conditioning system and a control method, and belongs to the field of air conditioners. According to the electrochemical air conditioning system, a firstintercepting pipeline is connected between an outflow pipeline and a backflow pipeline of a first hydrogenated metal heat exchanger, a second intercepting pipeline is connected between an outflow pipeline and a backflow pipeline of a second hydrogenated metal heat exchanger, and a cold and hot neutralization pipeline set is connected between the first hydrogenated metal heat exchanger and the second hydrogenated metal heat exchanger. According to the system, a switching signal is added between two continuous hydrogen reversing switching signals to carry out a heat neutralization mode, the first hydrogenated metal heat exchanger and the second hydrogenated metal heat exchanger are subjected to heat neutralization before cold and hot alternation so as to be prevented from changing from extreme hot into extreme cold, or from the extreme cold into the extreme hot, and the service life of a electrochemical compression refrigerating device is prolonged; in addition, the refrigeration mode or the heating mode can be kept after an electrochemical device stops running, comfortable cold air or hot air is blown out, the comfort and the stability are improved, and useless work is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an electrochemical air conditioning system and a control method. Background technique [0002] The electrochemical compressor is hydrogen (H 2 ) is supplied to the hydrogen compressor at the anode, and the compressed hydrogen is collected at the cathode at a pressure of up to 10,000 psig at 70% to 80% efficiency. Electrochemical compressors are noiseless, scalable, and easy to modularize. At present, they have been tried to be applied to new refrigeration systems. It is foreseeable that research on electrochemical refrigeration systems will receive increasing attention. [0003] As a refrigeration system application process, the electrochemical compression device generally includes an electrochemical compressor (ie, an electrochemical compressor pump), a first metal hydride reactor and a second metal hydride reactor communicated with both ends of the electrochemical com...
