It is mainly from the refrigerator, cooling water system, chilled water system, fan coil system and the composition of the cooling tower. The role of the various parts and how it works: refrigerator refrigerant through the compressor will be compressed into liquid evacuation evaporator heat exchange with chilled water, chilled water, refrigeration, freezing pump chilled water to the outlet of the cooling coil fan tube, cooled by a fan blowing to achieve the purpose. After evaporation of the refrigerant in the condenser after the release of the heat into the gas, cooling pump cooling water to cooling tower fan from the water tower to spray their cooling and heat exchange between the atmosphere, the heat emitted to the atmosphere go.
First. Central air conditioning system:
The central air conditioning system consists of the following components.
1. Chiller. This is the central air-conditioned “cooling source,” “Heart Tibet”, leading to various rooms for circulating water from the chiller “internal exchange”, cool as a “cooling water.”
2. Cooling towers. Used to provide cooling water for the chiller.
3. External heat exchange system. By two circulating water system components.
(1) chilled water circulation system. By the pump and chilled water pipes frozen form. Outflow from the chiller chilled water chilled by the chilled coolant pump pressure into the pipeline, in a heat exchange within the room, take away the heat the room is the room temperature drop.
(2) cooling systems. By the coolant pump and cooling water piping and cooling tower component. Chiller for heat exchange, is the cooling water temperature at the same time, will release a lot of heat. The heat absorbed by cooling water is cooling water temperature. coolant pump will be promoted to the temperature cooling water into the cooling tower, so that the cooling tower heat exchange with the atmosphere, and then lower and lower the temperature of cooling water, get back to chiller. This constant cycle of heat released chiller away.
4. Cooling fan. There are two situations: indoor fan installed on the need to cool down the room, will be chilled water for cooling the air blown into the room, to accelerate heat exchange within the room. Cooling tower fan, used to reduce cooling tower water temperature, speed up the “backwater” back to the heat emitted to the atmosphere.
Second, central air conditioning in the drive system:
1. Drag chiller system.
2. Coolant pump drive system. Composed by a number of pumps.
3. Coolant pump drive system. Composed by a number of pumps.
4. Fans (including the indoor fan and cooling tower fan) drive system.
