Water chiller central air conditioning system

Astronet Company Limited specializes in design consulting, construction and installation of central air conditioning systems

The central air conditioning system includes the following main parts:


1. Central air conditioner (CHILLER): A device that produces cold water through a pipeline system to supply heat exchangers installed in air-conditioned spaces to cool the air.

2. Heat exchangers (FAN COIL UNITs – FCUs): These are devices located in areas requiring air conditioning (the capacity of heat exchangers is selected based on the required cooling capacity of the room in which the types are installed. different), here cold water from the air conditioner passes through the condenser to exchange heat with the air in the room and perform the cooling function.

3. Cooling tower and water pump: perform the function of releasing heat energy from the condenser (air conditioner) after the air conditioner cools the water in the evaporator.

4. Cold water pump and pipeline system: Is the cold water distribution system from central air conditioning to FCU heat exchangers.

5. Cold air distribution pipeline system: Is the system that distributes cold air from FCUs through blowers to areas requiring air conditioning.

6. Electrical control system: Is a control system to interlock devices in the system (Air conditioner, FCU, Water pump and cooling tower).

System characteristics

- Central air conditioners can be placed on the roof or in the basement technical room, heat exchangers are placed in air-conditioned rooms (usually types of units installed in false ceilings and distributed cold air through through air ducts and blower doors placed in the ceiling), the cold water piping system distributed to the heat exchangers is placed in a technical box and on a false ceiling so the installation of the system does not affect the performance. architectural structure of the project.

- The cooling system is provided through a system of ducts and blowers from the ceiling to areas of the air-conditioned room, so the arrangement of the blowers to ensure the ability to evenly diffuse cold air in the room is absolutely necessary. can be done.

- For the central system, providing additional fresh air is very simple by installing AHU air mixing devices through the duct system to supply fresh air and mix it with the return air of each FCU. AHU. (this for local machines is difficult to do).

- Due to the water cooling system, the air conditioner runs stably during operation, less affected by outside temperature.

- The power consumption coefficient is lower and the ability to adjust the system's capacity is good, so during operation the air conditioner will automatically adjust the compressor capacity to ensure minimal reduction of power costs during operation. system operator. This significantly reduces operating costs for the entire system.

- High durability and longevity (over 15 years)

- There is a wide capacity range to choose from, you can choose a machine with a capacity suitable for different types of design projects and easily invest in expanding the system.
