Explosion-proof combined air-conditioning unit is the key equipment for handling air in the air-conditioning system. The unit is mainly applicable to explosive hazardous places where there are or may be IIA, IIB, IIC, T1~T4 groups of combustible gases, vapours and air mixed. 　　

The unit adopts the combination form of single or multiple functional sections. It is equipped with fresh and return air mixing section, middle and lower efficiency filtration section, fresh exhaust air section, intermediate section (maintenance section), secondary return air section, surface cooling section, heating section, water drenching section, anechoic section, humidification section, even flow section, supplying (return) fan section, and air outlet section, etc. The user can choose the combination according to the need. Users can choose the combination according to their needs. Unit combination is flexible, easy to disassemble, widely used in various industries, while according to user needs for non-standard unit design and manufacturing.
Features

1. less investment, high efficiency. Installation of evaporative air conditioners in the same area saves about 60% of equipment investment by installing central air conditioners.

2. less power consumption, low operating costs, only 1 degree per hour electricity. In the same area to install evaporative energy-saving air-conditioning, the power consumption is about 1/8 of central air conditioning.

3. air supply far, large air volume. Air flow per hour up to 18000m above.

4. clean air of good quality: ventilation, ventilation, purification, smell can be indoor with odor, dust and turbid hot air excreted outdoors, while the outdoor fresh air into the clean room, the air filter is good, right Dust filtration efficiency of more than 1μm in diameter is more than 80%.

5. the cooling effect is obvious: the general cooling unit can reach 4 ℃ -10 ℃, and rapid cooling.

Function introduction:

Initial effect section: 

Adopting non-woven plate type primary effect filter to preliminarily filter the large particle dust in the fresh air to meet the internal hygiene requirements of the unit and reduce the burden on the medium-efficiency filter section;

Medium efficiency filter section: 

the use of non-woven bag filter, filter air through the pipeline and the production of secondary dust, to reduce the burden of high efficiency filter or high efficiency filter;

Fan section:

 the use of low noise centrifugal fan, low noise, wind pressure; according to customer requirements, the choice of variable frequency control;

Surface cooling section: 

Table cold coil surface velocity ≤ 2.5m / s, and the use of hydrophilic membrane flat fin production, heat transfer effect is good and difficult to dust and bacteria, will not produce water phenomenon;

Heating section: 

hot water heating, steam heating, electric heating, etc .; electric heating using stainless steel light pipe, smooth surface without fin, corrosion resistance, easy to fouling, easy to clean;

Humidification section: 

Dry steam humidification or electrode humidification can be used to ensure that there is no accumulated water in the humidifier after the shutdown, so as to eliminate the possibility of bacteria growth in the humidifier.

Sterility: 

UV or ozone generator can be used for sterilization, completely destroy the bacteria living environment
