Application of soft sensor technology in HVAC system test

With the rapid development of modern society, measurement and control requirements key variables air conditioning test technology are also increasing. When parameters HVAC system measured controlled, there a large number sensors instruments used. sensor failure or error distortion occurs, cannot operate normally automatically. At same time, some in be directly collected by sensor. In order to solve these problems, researchers have focused on soft recent years, which provides good breakthrough for parameters. This paper expounds application system.
