Indoor air conditioning under various environmental conditions has multiple functions such as cooling, dehumidifying, heating, humidification, and ventilation. Temperature control range: When the temperature is set at 18~25 ℃, the control accuracy is ± 0.5~1 ℃, the relative humidity is set at 50~70%, and the control accuracy is ± 5~10%. The unit has a variety of models to choose from, and can be widely used in electronic factories, hospitals, pharmaceutical factories, printing plants, post and telecommunications, banks, computer rooms, power supply and distribution stations, communication stations, and other buildings for air conditioning needs. It has the characteristics of mature technology, compact structure, simple installation, stable and reliable performance, and fully meets the needs of precision machinery, optical instruments, electronic instruments, printing, medicine, food processing, and other workshops and measurement rooms Places where scientific research laboratories have high requirements for temperature and humidity.

Cooling principle: During the operation of the refrigeration system, the high-temperature and high-pressure R410 gas discharged by the compressor enters the condenser and is condensed into a medium temperature supercooled liquid. After being throttled and depressurized by the expansion valve, it becomes a mixture of low-temperature and low-pressure vapor and liquid, which enters the evaporator. The mixture evaporates inside and absorbs the heat of the air passing through the evaporator, cooling the air flowing through the evaporator. After vaporization, the steam is sucked in by the compressor, thus continuously circulating, So as to achieve the purpose of cooling.

Humidity reduction principle: Due to the fact that the surface temperature of the evaporator fins is lower than the dew point temperature of the air, when the air flows through the evaporator surface, there is water precipitation on the evaporator surface.

Heating up: Start the heater, and when the air flows through the heater, the air is heated and warmed up.

Humidification: Start the humidifier, and the water vapor generated by the humidifier is continuously sent into the room by the fan for humidification purposes.
