3、 Three major systems:

1. Refrigerant circulation system:

The liquid refrigerant in the evaporator absorbs heat from the air (the air is cooled and dehumidified) and begins to evaporate. A certain temperature difference is formed between the refrigerant and the air, and the liquid refrigerant also evaporates into a gaseous state, which is then sucked in and compressed by the compressor (pressure and temperature increase). The gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled) and condenses into a liquid. After being throttled by an expansion valve (or capillary tube), it becomes a low-temperature and low-pressure refrigerant that enters the evaporator, completing the refrigerant circulation process.

2. Air environment system:

The fan is responsible for inhaling air from the return air outlet. The air passes through the evaporator (for cooling and dehumidification), humidifier, and electric heater (for heating) before being sent to the user's desired space through the air supply outlet. The air sent out mixes with the air in the space and returns to the return air outlet.

3. Electrical self-control system:

Including power supply and automatic control parts.

The power supply is automatically controlled by contactors to supply power to compressors, fans, electric heaters, humidifiers, etc. It is further divided into temperature and humidity control and fault protection parts: temperature and humidity control is achieved by comparing the temperature and humidity of the return air with the user set temperature and humidity through a temperature and humidity controller, automatically running the compressor (cooling, dehumidification), humidifier, electric heating (heating) and other components to achieve automatic control of constant temperature and humidity.
