Method of controlling air-cooling device and air-cooling device

Abstract

The present invention discloses a method of controlling an air-cooling device and an air-cooling device. The air-cooling device enables two chambers to achieve simultaneous refrigeration, to achieve simultaneous heating, or to achieve refrigeration in one chamber and heating in the other chamber by employing a structural design with a single evaporator+a single evaporation blower+two dampers+three heating wires, in conjunction with the control of operational relationship of the compressor, the evaporation blower, the heating wires and the dampers; in conjunction with the control in the above three manners, the thermostatic control of the air-cooling device with a single refrigeration system and dual temperature zones is achieved with a simple structure and process.
