Electronic expansion valve is a kind of intelligent control product. Compared with the simple mechanical thermal expansion valve, it has obvious advantages. In the future, the products of refrigeration and air conditioning industry will become more and more intelligent, humanized and efficient. With the rapid development of Internet of things, remote control, precise sensing and other new things, this is the inevitable trend of people's lifestyle changes.
However, in the refrigeration market, the requirement of energy efficiency is not so urgent. At present, most of them are thermal expansion valves. However, electronic expansion valves have been widely used in large-scale machines. The first reason is the problem of product selection. Many customers may not match their design conditions and applications in the process of selection, which may cause unnecessary confusion and even application problems. The second is the control logic of electronic expansion valve, which is a headache for small and medium-sized enterprises with weak technical force.
