The central air-conditioning system is mainly composed of a refrigerator, a cooling water circulation system, a chilled water circulation system, a fan coil system and a cooling water tower. The refrigerant is compressed into a liquid by a refrigerator through a compressor and the heat is exchanged with the frozen water in the evaporator after the refrigerant is compressed into a liquid. The chilled water is refrigerated, and the chilled water is sent by the chilled water pump to the cooling coil in the air of each fan, and the cold air is blown by the fan to achieve the purpose of cooling down. After evaporating, the refrigerant releases heat in the condenser and carries out heat exchange with the cooling circulating water. The cooling pump that brings heat is sent by the cooling pump to the cooling tower for spray cooling by the tower fan, and the heat is exchanged between the cooling water and the atmosphere. Radiating heat into the atmosphere. 

The central air-conditioning system is a huge equipment group. The central air-conditioning group control system designed and developed by our company can be used to monitor the operation status and faults of the chillers. Remotely setting the outlet temperature and full load current of the chilled water of the chiller, starting and stopping the chiller by remote control, monitoring the status of the chilled water pump and cooling tower, It can also adjust the pressure difference, monitor the temperature of total return water of cooling water, monitor the operation situation of frozen water in each branch, the electric butterfly valve of cooling water circuit and the fresh air conditioning unit, etc., and can also adjust the pressure difference, monitor the temperature of the total return water of cooling water, and monitor the operation situation of the electric butterfly valve of the cooling water circuit and the fresh air conditioning unit, etc. It can meet the requirements of centralized monitoring, remote monitoring and debugging, humanized alarm, alarm record query, database query, export and print, information logging and other functions.


中央空调系统主要由制冷机、冷却水循环系统、冷冻水循环系统风机盘管系统和散热水塔组成,制冷机通过压缩机将制冷剂压缩成液态后送蒸发器中与冷冻水进行热交换,将冷冻水制冷,冷冻水泵将冷冻水送到各风机风中的冷却盘管中,由风机吹送冷风达到降温的目的。经蒸发后制冷剂在冷凝器中释放出热量,与冷却循环水进行热交换,由冷却水泵将带来热量的冷却水泵到散热水塔上由水塔风扇对其进行喷淋冷却,与大气之间进行热交换,将热量散发到大气中去。


中央空调系统是一个庞大的设备群体,我司设计开发的中央空调群控系统可以集中监测冷水机组的运行状态和故障,远程设定冷水机的冷冻水的出水温度和满负荷电流、遥控冷水机的开停、监控冷冻水泵、冷却水泵、冷却塔的状态,故障和开停、监测冷源系统冷水供水回水温度、流量、压差,并可调整压差,监测冷却水总回水的温度,监控各分支冷冻水,冷却水路的电动蝶阀及新风空调机组等运行情况,可以很好的满足集中监控,远程监控和调试,人性化报警,报警记录查询,数据库查询,导出和打印,信息日志化等各类功能。
