Underground engineering dehumidification, Shanghai Zhongyou with fist products debut 2020 China Heat Pump Exhibition

Underground engineering compared with surface engineering, a very prominent problem is humidity。In summer，The difference in specific enthalpy of air inside and outside underground works is very large，The ordinary dehumidifier does not have enough cooling capacity to control the dew point temperature of the fresh air low enough，It is difficult to ensure that there is no condensation after fresh air enters the underground works，It brings many problems to the design and operation of ventilation dehumidification system.At the same time, the suitable air after indoor treatment is directly discharged to the outdoor will also cause energy waste。

Based on this，Shanghai Zhongyou Industrial Co., LTD，Set more than 40 years of air conditioning dehumidification equipment professional design and manufacturing experience，Through a large number of data collection and analysis，For underground engineering or similar underground engineering use environment，Serial development of underground engineering constant temperature dehumidifier，Applicable to *, civil air defense projects, subway stations, space bases, underground shopping malls, underground entertainment centers and other places that have both general air conditioning and dehumidification requirements。

From July 30 to August 1, 2020, Zhongyou Industrial will bring underground engineering constant temperature dehumidifier (Model: CK9-DX) and other products to participate in the 10th China Heat Pump Exhibition held in Shanghai, booth No. B342。

The unit product number 9090592, the use of a new design concept, customized for the thermal and wet load characteristics of underground engineering, and the use of a large number of new materials, new technologies and new processes, the unit has a central air conditioner and dehumidifier two functions, truly achieve a multi-purpose machine。It has the following characteristics:

1. Energy saving operation - heat recovery: The use of condensing heat as the secondary heating source of the air conditioner reduces the operation cost of the unit, saves the operation energy consumption, and comprehensively improves the energy saving index of the unit。The unit is a multi-functional combined dehumidification air conditioning equipment with its own cold source (direct evaporation type)，Set refrigeration system, ventilation system and control system in one，Compared with units using chilled water as secondary refrigerant，Simple and efficient，Increase efficiency by more than 10%;Evaporator layout design，Make full use of the evaporator area，At 50% load，Evaporator efficiency increased by more than 30%，High refrigeration efficiency。The unit is easy to install, and can be run only by wiring and taking over on site。

• Environmental protection working medium, "green" concept: The unit uses R22 refrigerant that meets the requirements of the national program to eliminate CFC working medium, which is advantageous于Earth environment。The company can also customize the dehumidifier with HFC working medium such as R407C and R134a according to user requirements。

Shanghai Zhongyou Industrial Co., Ltd. is a professional manufacturer of air technology treatment products such as dehumidification, humidification and refrigeration equipment, integrating design and development, product production, marketing and technical service。In 2010, the company actively participated in the construction of Shanghai World Expo with great success, in which high-quality industrial dehumidifier was applied to the World Expo pavilion。The product series developed by the company are: dehumidifier, humidifier, dehumidifier, dehumidifier, rotary dehumidifier, temperature control dehumidifier, pipeline dehumidifier, explosion-proof air conditioner, explosion-proof dehumidifier, constant temperature and humidity machine, unit air conditioner, direct expansion air treatment unit, combined air conditioner unit, air (water) cold water unit, etc，Mainly used in places with high ambient air humidity requirements，Can significantly improve the environmental humidity and purify the air。

China Heat Pump Exhibition has been successfully held for 9 sessions, is the current domestic air source heat pump industry specifications较High professional exhibition。Its exhibitors to air source heat pump hot water, heating, special applications of the upstream and downstream industry chain, taking into account other types of clean energy heating, ventilation, water related industry chain and so on more than 350。The exhibition area is nearly 5.50,000 square meters, it is expected that the professional audience will be more than 55,000 people/time, is the air source heat pump and even clean heating industry较大、较Professional annual event。It integrates various forms of activities such as exhibition, summit forum, new product release, procurement conference, thousand people heat pump open class, and is actually a cutting-edge platform for the heat pump industry to display and publicize to the whole country and even the world。
