1. WHAT IS CENTRAL AIRCRAFT SYSTEM?

With specific industries such as pharmaceutical technology, electronic technology, textile technology, etc., they always require a very hard working environment in terms of moisture conditions to ensure the best quality of products. .
The system guarantees the technical parameters of temperature, humidity, concentration of dust, bacteria, oxygen content, pressure and air velocity in a certain space according to the standards of Vietnam and the United States. . The current technology in the market is focused on two main technologies: Central air conditioning system and VRV air conditioning system.
If the inverter is used in the central air conditioning system is the optimal solution for the reasonable design, energy-saving operation. It also combines with the control system of the building to modernize and save maximum use of energy and ensure the security issues, fire prevention in the building.
The central air conditioning system is a new technology that has been developed very well by the wide application efficiency in the industry and civil. The key point here is that the compact system ensures the aesthetics and special requirements of this system are very good for high-rise buildings.
2. PRINCIPLES OF OPERATION OF CENTRAL AIR-CONDITIONING SYSTEM
The principle of operation of this system is as follows:

The system includes CHILLER chillers, FCU / AHU heat exchanger, Cooling Tower, chilled water pumps, air pipes and water pipes, control valves.

The water is circulated through the CHILLER and is cooled to 7 ° C and then flows through the FCU / AHU heat exchanger. Here the chilled water is exchanged with the circulating air in the room and the room temperature drops. Cold water is absorbed with hot air in the heating chamber up to about 120C, circulating pump back to CHILLER, where the water is kept cooled down to  7 ° C and the cycle continues. Thanks to the pump system, the system can be transported further and higher
