Cooling buildings is the cooling system operates under two principles:

The cooling system and positive pressure cooling system, negative pressure

The cooling system is a positive pressure system blows cold air into the factory, are made up of a combination of the following devices:

1. System cooling machine factory capacity, heavy traffic
2. Pipeline cold wind at workshops
3. Door Systems Wind: cool air distribution in factories
4. System racks, machine bed
5. Pools circulatory system
6. Water Pump System: Providing water for cooling machines
7. The control panel: Controlling the switching devices in the system
8. Equipment and supplies electrical systems

Coolers Factory installed spread over the entire premises (cooling the whole), or can only be installed in the position to focus employees (local cooling). So with this system saves investment costs and power consumption while creating a cool environment to work.
When active cooling system partially evaporating water into the air to cool down, the rest is returned to continue a new cycle, and always have a supply of water is added to compensate the country has lost part due to evaporation. Just because water is recirculating system should be very thrifty and economical, the amount of water changing system makes operation more efficient, source of air blown into the plants will be cleaner and cooler.

Features of the cooling system factory positive pressure:

The investment costs and low operating: Investment costs by 30%, energy consumption by 10% compared with the air conditioning system tradition.

High efficiency: The air is filtered through the machine to clean, reducing the temperature, oxygen levels increased and compensated humidity, creating an ideal working environment to help increase productivity and ensure the health of workers.

The cooling system is negative pressure cooling system by: A gable factory installation of industrial vacuum fans with large air flow to suck all the hot air, industrial pollution and dust in waste workshop go out.

At the workshop gable facing industrial exhaust fans installed truss frame heat exchangers (heat exchanger skeletons is constituted by the cooling plate (plate heat exchanger), the cooling plate is pump regular supply of water by watering them on top of the sheet resistance distribution face then moisture permeability over the entire surface of the cooling plate. water cooling after the last plate of the gutter system and water withdrawal pipe back the tank to the new cycle. the air is hot and dry from the outside through the cooling plate, heat exchanger directly with water and become clean and cool air, creating appropriate moisture and temperature reduction not workshop air.

Reality has proven cooling system more efficient factories so than conventional air conditioning systems.
- Easy Installation construction, does not affect the operation of workshop
- Do not damage the ozone layer, protecting the environment
- Power Savings
- Investment costs only 1/3 compared to air conditioning and operating cost is only 1/10 with air conditioning
- This system reduces the temperature from 5-10oC, eg outdoor temperature is 35oC, when using this cooling system, the temperature in the factory only from 25-28oC.
