When summer weather is hotter, heater 602 is out of work, and the refrigerator work is sent cold water into surface cooler 601, and cold water in the surface cooler 601 can absorb the heat that holds the intracavity air for air temperature reduces, and the air after the temperature reduction finally can get into workshop 1000 in, cools down workshop 1000. Other working principles are the same as the heating condition, and are not described in detail.

In spring or autumn, only air needs to be supplied to the workshop 1000, and heating or refrigeration is not needed, so that the surface air cooler 601 and the heater 602 do not work, and at the moment, water in the water tank 300 enters the surface air cooler 601 without refrigeration, so that the air entering the workshop 1000 can be in a natural temperature state.
