Air-conditioning systems what is

The air conditioning system is a system of one or more air coordination center into an overall cold distribution system for the whole of the area in the building. The Central conditioners systems use water as cold through the plumbing system on the secondary heat exchanger to cool the air.

Central air conditioning systems include the main section:

Air conditioning Centre (CHILLER): is the device that produces cold water pipeline systems provide the seamless exchange of heat installation in the space conditioning to cold air.

The secondary heat exchanger (FAN COIL UNITs-FCUs): Is the equipment located in the area need to regulate (the capacity of the secondary heat exchanger is selected based on the requirements of the cold room capacity that fitting different types), where cold water from air conditioning to go through staging cold to heat exchange with the air in the room and make the cooling function.

Cooling tower and water pump: make the function frees the heat energy of the condenser (air conditioning) after the air conditioning made the cooling water in the average volatility.

Piping systems and pumping water level conditioning: Is the distribution system of cold water from air conditioning central heat exchanger conductor to the FCU.

Distribution pipeline system of cold air distribution system: the cold air from the mouth through the FCU blown to areas in need of conditioning.

Electric control system: the control system Is to control the dynamic contact system equipment (air conditioning, FCU, pump water and cooling tower)

Characteristics of air-conditioning system in this Center:

-Central air conditioning can put on the roof or in the engineering room of the basement, the secondary heat exchanger placed in rooms conditioned (usually is the most recent in the false ceiling and distribute cold air through the wind pipe and blow set in the ceiling), the cold water pipe system distribution for the seamless exchange of heat is going in the box techniques and on the false ceiling so the installation of the system do not affect the architectural structure of the work.

-The level of conditioning was via duct system and the mouth blowing from the ceiling down to the area of room conditioned so that the arrangement of mouth blown to ensure diffusion of air conditioning in both rooms is entirely possible.

-The central system for the grant of additional fresh air very simply by the mounting duct system via the device blended air supply fresh air AHU and blended with the air to each of the FCU , AHU. (this is for the local machine are difficult to accomplish).

-Water-cooled system should be in operation air conditioning running stable, unaffected by the outside temperature.

-Low power consumption coefficient more likely to adjust the capacity of good system so that in the course of operating the air conditioner automatically adjusts compressor capacity to ensure minimum electricity cost reduction during the operation of the system. This significantly reduces operating costs for the entire system.

-High service life and durability (over 15 years)

-Has the power to choose, can choose the type with capacity consistent with the design process and expand the system easily.

At present, in the field of the air conditioning system can pretty much be used for works have different uses and different architectural features. Can distinguish these systems through a number of characteristics. However can generalize into some basic system:

* Water cooling system:

-Water cooling system, cooling condenser with water.

-Cooling system with water cooling, cooler by wind.

In this system, including the main equipment such as:

air conditioning Center

the staging, heat exchangers, condenser cooling equipment, the water pump, …

Cold water produced in the central air conditioning to be granted to the secondary heat exchanger placed in the space conditioning. Here, water as a heat-exchange agent, made the process of getting heat from the environment, reduce (increase) the temperature, the humidity in the room. After this process is finished, the water back to the circulation of air conditioning Center and continue a new cycle.

This system fits the requirements for the conditioning of different space have temperature-humidity mode. (in each separate space we can choose a temperature-humidity as you like, depending on how to control in that space)

Installation space requirements for the system are not very high. The gap between the false ceiling and bottom beams range from 100-200 mm is possible.

* Cooling system by wind:

-Wind-cooled system, cooling condenser with water.

-Wind-cooled system, condenser cooling by wind

In this system, including the main equipment such as air conditioning, the center channel distribution of wind and wind chill, heat the condenser …

Different to the first, in this system, air conditioning central produce wind and cold to the space conditioning through the Channel Guide. Here, the wind is cold heat-exchange agent, made the process of getting heat from the environment, reduce (increase) the temperature, the humidity in the room. After this process is finished, the wind chill on air conditioning circulation back to the Center through a channel leading wind (or feedback directly on the cameras) and continue a new cycle.
