Principle and Application of Thermostat Dehumidifier

The temperature-adjusting dehumidifier uses an evaporator to cool and dehumidify the air so as to recover the condensation heat of the system to make up for the heat lost in the air due to cooling and dehumidification. It is an efficient and energy-saving dehumidification method. It has been widely used in places where there is a requirement for dehumidification, such as defense engineering, civil air defense engineering, tobacco and petrochemical industries, subway stations, aerospace purification engineering, laboratories, telecommunications equipment rooms, archives, food rooms, pharmaceutical or film workshops, special glass manufacturing, food and wood storage, etc. China has a variety of climate types. The temperature difference between winter and summer is large in most areas, and the heat / cold / humidity load changes significantly with time. The traditional dehumidification and drying system cannot meet the actual needs well.

The intelligent dehumidifier is to provide a temperature-adjusting and humidity-adjusting method and equipment that can heat, cool and dehumidify the room under different indoor and outdoor temperatures to meet the requirements, and can improve the performance of the dehumidification and temperature-adjusting system, as well as expand the scope of application of the dehumidification and temperature control system.

Dehumidifier can be divided into commercial dehumidifier and industrial dehumidifier. Besides, you can choose different kind of dehumidifiers according to different occasions. If you want to breathe fresh air at office, there is industrial humidifier for office for you and if you work in the basement, there is industrial humidifier for basement for you. If you are in constant movement, you can choose a portable dehumidifier and better, a mini portable dehumidifier.

When the indoor temperature and humidity are relatively high, and the indoor cooling load is relatively large, the system operates in the cooling and dehumidifying mode. At this time, the four-way valve is not energized, the system operates in cooling mode, the indoor second heat exchanger branch is closed by the solenoid valve, the outdoor heat exchanger is the condenser, and the indoor first heat exchanger is the evaporator. The indoor air is only cooled and dehumidified by the first indoor heat exchanger, and the low-temperature and low-humidity air returns to the room. In this mode, you can also adjust the air volume or water volume of the outdoor heat exchanger to further adjust the cooling capacity and dehumidification capacity. Both the cooling capacity and the dehumidification capacity increase with expand of the air volume or water volume of the outdoor heat exchanger.

When the indoor humidity and humidity load are relatively high, and the indoor cooling load is relatively small, the system operates in the temperature adjustment and dehumidification mode. At this time, the four-way valve is not energized, and the system still operates in the cooling mode. The outdoor heat exchanger and the indoor second heat exchanger are two parallel condensers, the indoor first heat exchanger is an evaporator. After the indoor air is cooled and dehumidified by the first indoor heat exchanger, passing through the second indoor heat exchanger, it is reheated by partial condensation heat, and the air returns to the indoor. In this mode, the air volume and water volume of the outdoor heat exchanger can also be adjusted to further control the indoor reheat, thereby achieving the purpose of controlling the indoor air temperature.

When the indoor humidity and humidity load are relatively high, but the indoor temperature is low and the heat load is relatively small, the system operates in the heating and dehumidification mode. At this time, the four-way valve is not energized, the system operates in cooling mode, the outdoor heat exchanger branch is closed by the solenoid valve, the indoor second heat exchanger is a condenser, and the indoor first heat exchanger is an evaporator. Since the high-temperature refrigerant also flows through the indoor second heat exchanger 2, after the indoor air is cooled and dehumidified by the indoor first heat exchanger, all the heat of condensation passing through the indoor second heat exchanger is used to reheat the air. In this mode, since the refrigerant flow path of the outdoor heat exchanger is shut off, all the heat of condensation is borne by the second indoor heat exchanger. The heat of condensation in the system is greater than the heat of evaporation, so the humidity of the air drops and the temperature rises.
