Application Field, Structure and Principle of Temperature Regulating and Dehumidifying Machine

Temperature regulating dehumidifiers use evaporators to cool and dehumidify the air, and recover the condensation heat from the system to compensate for the heat lost during cooling and dehumidification. They are an energy-saving dehumidification method and have been widely used in national 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, grain Places with dehumidification requirements such as dehumidification and drying of wood and dehumidification and temperature control in high humidity spaces.
In China, there are various climate types, with a large temperature difference between winter and summer in most areas. The heat/cold/humidity load varies significantly over time, and traditional dehumidification and drying systems cannot meet practical needs well. Therefore, in many occasions, it is necessary to use a temperature regulating dehumidifier to control temperature and humidity in order to achieve good drying results. The major difference in functionality compared to other dehumidifiers is that it can adjust indoor humidity, such as heating or dehumidifying, while dehumidifying. Used in special working conditions where environmental temperature is relatively sensitive and dehumidification is also required, with a control range of 18 to 28 ℃ ambient temperature and 40 to 80% RH humidity.

The temperature regulation and dehumidification unit is divided into indoor and outdoor units, consisting of a compressor, a four-way valve, an outdoor heat exchanger, an indoor second heat exchanger, an indoor first heat exchanger, an expansion valve, and other refrigerant pipelines connected to form a refrigeration cycle. The outdoor heat exchanger and the indoor second heat exchanger are connected in parallel, and an electromagnetic valve is installed on the branch of the indoor second heat exchanger to control the opening and closing of the branch.
At the same time, professional ventilation duct design is used to achieve long-distance cooling transmission, thereby meeting the different air supply characteristics of various buildings; Recycling the condensation heat from the system to compensate for the heat lost in the air during cooling and dehumidification is an energy-saving dehumidification method.
Dongjing series air-cooled temperature regulating dehumidifiers are equipped with fully enclosed refrigeration compressors, expansion valves, solenoid valves and other parts, which are all imported products. The control switch adopts touch buttons. The operation panel has the function of working operation indication and fault display. The fan equipped with the unit is a high-performance, low-noise centrifugal fan; The unit with low noise, large air volume, and high static pressure can be controlled. Communication interfaces are configured according to user requirements to achieve remote computer centralized control and display. The unit operates smoothly, is easy to operate, has a beautiful appearance, and has a small maintenance workload.
