The identification model of the heat outlet temperature is applied in internal model control which achieves the better control effect and supplies a feasible solution for the industrial application.

For instance, we squander about 30 percent of the energy in our homes. What's surprising is the amount of heat we lose through the area behind electrical outlet junction boxes.

At a given air inlet condition and airflow rate, meanwhile, dryness of air outlet was required, proper heat-transfer area and matching refrigeration system are obtained through calculating.
