Problems solved by technology
[0002] The compressor is the heart of the refrigeration system. It absorbs or releases heat through physical or chemical changes, thereby producing a cooling effect at the heat-absorbing end. With the development of science and technology, the disadvantages of traditional vapor compressors are becoming more and more prominent. Some efficiency Higher compressors, such as more efficient compressors such as electrochemical compressors, electromagnetic compressors, and stress compressors, are being used more and more, but electrochemical compressors, electromagnetic compressors, and stress compressors are often used It is more efficient, but the heat exchanger is always changing between cold and heat. In the actual application process, it cannot guarantee that one end is always refrigerated, so an auxiliary heat exchange device is needed to conduct the temperature.
[0003] In the technology currently used, pipelines and three-way valves are used to form a heat exchange system. Through the heat exchange system, one end is always cooled and the other end is always heated. However, in this scheme, four three-way valves are used to realize one-way disconnection. The function of two-way connection, and there are intersections in other pipe fittings, the layout of the entire line is difficult to realize, the efficiency of secondary heat exchange is low, and it is difficult to realize. At the same time, the market consumption of three-way valves is larger than that of four-way valves. Less, higher unit price, and less stable operation in the presence of critical intersections

Description
technical field [0001] The present invention relates to the technical field of air conditioning and refrigeration, in particular to a heat exchange device, an air conditioner and a method for controlling the air conditioner. Background technique [0002] The compressor is the heart of the refrigeration system. It absorbs or releases heat through physical or chemical changes, thereby producing a cooling effect at the end of the heat absorption. With the development of science and technology, the disadvantages of traditional steam compressors are becoming more and more prominent. Some efficiency Higher compressors, such as electrochemical compressors, electromagnetic compressors and stress compressors and other more efficient compressors are being used more and more, but electrochemical compressors, electromagnetic compressors and stress compressors are often It is more efficient, but the heat exchanger is always changing between cold and heat.
