Detailed introduction

品牌ZHONGYOU/ Zhongyou

Air-cooled constant temperature and humidity machineProduct features:

    The main parts of this product, such as refrigeration compressors, filters, etc., are made of * products。The unit has a variety of automatic protectionCompared with other similar products, it has the characteristics of high efficiency, compact structure, smooth operation, easy operation, beautiful appearance, long service life and so on。

1) Shape structure

The unit uses high-strength steel as the frame, novel appearance, simple and reasonable mechanism, easy installation, internal use of anti-corrosion materials, effectively increase the service life of the product。

2)功    能

     本机It has three functions of regulating temperature and dehumidification, heating and dehumidification, and ventilationWhen the humidity is relatively large, the dehumidification function is used, and the ventilation function is used when the humidity is small。This can not only meet the requirements of humidity, but also achieve the effect of energy saving

3)配    件

     The compressor and main accessories are used in the product, through the scientific and reasonable optimization design of the refrigeration system, to ensure the normal operation in different environments。It has overcome the shortcomings of insufficient dehumidification of domestic models and high failure rate of units with frequent start-up。At the same time, it also improves the service life of the product。

 4)控    制

   The unit adopts microcomputer control, which can automatically start and stop according to the relative humidity set by the user, with high precision, good reliability, beautiful appearance and easy operation。

5)保    护

     The unit has temperature and humidity display, fault display and other functions。Equipped with overload, short circuit, lack of phase, overheating, high pressure, low pressure and other protection, and fan, fire valve chain protection。

Working principle and flow chart

1, the machine has temperature control dehumidification, humidificationRising and cooling dehumidification and humidification通风、加热Three functions, the user can choose any function according to the need。

2, indoor wet air through the surface of the evaporator, because the evaporator temperature is lower than the dew point temperature of the wet air, the water vapor in the air will condense out, accumulate in the water tray, discharged by the water pipe, the moisture content of the air decreases。After dehumidification, the wet air is heated up through the air-cooled condenser, and its relative humidity decreases, so as to achieve the purpose of drying the ambient air。
