Control the pressure switch of the cold and dry machine fan is measured what pressure
Condensing pressure, to a certain pressure will jump, down to a certain pressure will jump
Under such a principle, when the temperature rises, the system needs to cool down, in the form of pressure to the pressure switch command cooling fan start, cooling the condenser cooling, reduce the condensation temperature.
In the cold and dry refrigeration system, the temperature and pressure are one by one, when the temperature is high when the pressure is also large.
