Overview
On the basis of integrating direct evaporative cooling technology and external cooling indirect evaporative cooling technology, this product can add other functions such as medium and high efficiency filtration, mechanical refrigeration section, surface cooling section, heating section, muffler section and humidification section according to actual engineering needs. It adopts modular design and has the characteristics of high efficiency and energy saving, stable operation, anti-freezing and low noise. It can be used for fresh air cooling in public construction projects and industrial workshops in dry areas, and can replace mechanical refrigeration. The energy saving effect is very obvious. It is also suitable for energy-saving cooling in various data centers, computer rooms and power distribution rooms.
Working Principle
Features
1. The direct evaporative cooling technology is adopted, and the outdoor dry air can be fully utilized to reduce the energy consumption of the fresh fan operation, and the energy saving effect is outstanding.
2. The unit adopts anti-cold bridge aluminum alloy frame, seamless socket splicing panel, high-pressure polyurethane insulation board, which has good thermal insulation performance and sealing performance.
3. The filler made of plant long fiber material or polymer material has a flame retardant grade of B1, a water absorption efficiency of up to 250%, an evaporation efficiency of up to 95%, long life, no peculiar smell, and no harmful substances such as phenol. Comply with environmental ROHS and REACH certification requirements.
4. The unit has a built-in water tank, which can be recycled. It adopts advanced water distribution design, low wind speed on the windward side, no floating water, long water exchange cycle, and reduces water consumption and pump energy consumption.
5. The unit can be equipped with primary, medium and high-efficiency filter screens, and the filter grades are optional. The function section is set reasonably, and the heating section, mechanical refrigeration section, etc. can be selected according to the actual use requirements.
6. The ratio of mechanical refrigeration system can be adjusted according to actual requirements, and the energy efficiency ratio is higher.
7. Intelligent control, using a central controller, can realize automatic adjustment of air volume, temperature and humidity control, fault alarm, and group control of multiple units.
Application
Data centers, hospitals, schools, airports, high-speed rail, shopping malls, libraries, gymnasiums, exhibition halls, etc.
Optional Function (Non-Standard)
