Problems solved by technology

[0002] In air-cooled equipment such as wine cabinets, for products with dual temperature zones, it is usually realized by using a single evaporator + double evaporator fans. When a room needs cooling, the compressor runs, and the corresponding evaporator fan runs. Corresponding to the cooling of the compartment; although this method is simple in structure, it is serious in mutual cooling, and cannot achieve constant temperature at low ambient temperature
[0003] Constant temperature control can ensure the storage and best taste of stored products such as wine. In order to achieve constant temperature control, the existing technology usually uses double evaporators + double evaporator fans + two heating wires + solenoid valves for control switching. When When the first room needs cooling, the solenoid valve switches the first room, the evaporator in the first room is cooled, and the evaporator fan in the first room runs; when the second room needs cooling, the solenoid valve switches the second room, the second room The evaporator in the two rooms is refrigerated, and the evaporating fan in the second room is running; the two rooms are switched back and forth, and when each room needs to be heated, the heating wire in the room is started, and the evaporating fan is running; although this method can achieve constant temperature control , but there are problems such as complex structural design and cumbersome production process

Abstract

The invention discloses a control method of air cooling equipment and the air cooling equipment. The air cooling equipment adopts a structural design of a single evaporator, a single evaporation fan, two air doors and three heating wires, and is combined with control over the operation relation of a compressor, the evaporation fan, the heating wires and the air doors; so that two chambers can operate through the compressor and the evaporation fan, and the first air door and the second air door are opened to achieve simultaneous refrigeration. Simultaneous heating can be realized by stopping the compressor, operating the evaporation fan, opening the first air door and the second air door, and starting the first heating wire, the second heating wire and a compensation heating wire. Through operation of the compressor and the evaporation fan, the first air door is opened, the second air door is closed, the second heating wire is started, and single-chamber refrigeration and single-chamber heating are achieved in combination with limitation of conditions such as refrigeration and heating requirements and defrosting temperature. By combining the control of the three modes, the constant-temperature control of the single-refrigerating-system double-temperature-zone air cooling equipment is realized through a simple structure and a simple process.
