Commercial & Industrial HVAC Systems

Advantage:

1.Applied to dry areas;

2.Compact structure, installed on the roof, convenient for installation, do not take up too much space ;

3.Sufficient external static pressure, suitable for connecting air duct system, reduce indoor noise greatly;

4.Cooling capacity:meet different requirements;

5.The framework of units is anti-cold bridge aluminum alloy, which eliminates cooling leakage and condensate water due to large temperature difference between inside and outside.

6.The main parts are imported quality products, with excellent performance;

7.The evaporator and condenser adopt the technology of enhancing heat transfer, which makes the exchanger of high efficiency and save energy.

Features

1. Operating temperature range:-40~45°C.

2. G4 filters to provide engine room with clean air, clogged filtration cotton can automatically detect and automatically replace, which reduces labor costs and traffic costs.

3. Integration of indoor and outdoor unit designed to meet unmanned engine room equipment burglar requirements, no brass indoor and outdoor unit is connected, reducing the risks of refrigerant leakage.

4. When the outside temperature reaches fresh air ventilation working condition, compression refrigeration system is shut down, the introduction of natural cold air outside cool room environment. In fresh air mode, energy efficiency ratio can reach 18 to achieve the unit's energy-saving operation.

5. Large area of heat exchanger design, the choice of large airflow blower, so that air circulation inside the room can be one hour of dozens of times, then the room temperature is balanced to prevent local overheating, to achieve room environment precise control of temperature and humidity.

6. Design of high sensible heat ratio (sensible heat ratio of more than 90%), compare with ordinary air condition to save 20-30 % of energy consumption in the refrigeration mode, and thus avoid excessive dehumidification and supplying air with fog.

7. Sleep mode is designed to run: when the room temperature and humidity reaches the set value, not only to stop the operation of the compressor, but also the fan.
