Background technique

With the improvement of requirements for energy saving and emission reduction and the emergence of a large number of high-rise buildings and intelligent buildings, the application of central air-conditioning systems in buildings has developed rapidly. Similar to general air conditioning, the central air conditioning system is mainly composed of refrigeration units, cooling water circulation system, chilled water circulation system, fan coil system and cooling tower. The refrigerator compresses the gaseous refrigerant through the compressor, and the high-pressure gaseous refrigerant enters the condenser to exchange heat with the cooling circulating water. The cooling water pump sends the cooling water with heat to the cooling tower and is sprayed by the water tower fan. Cooling, heat exchange with the atmosphere, and dissipate the heat to the atmosphere; the liquid refrigerant formed by condensation enters the evaporator, exchanges heat with the chilled water, reduces the temperature of the chilled water, and the chilled water pump sends the low-temperature chilled water to In the cooling coil of each fan outlet, the fan blows cold air to achieve the purpose of cooling.
