中央空调系统是现代大型建筑物不可缺少的配套设施之一,电能的消耗非常大,约占建筑物总电能消耗的50%。现主要介绍了采用楼宇自动化系统(BAS)实现对空调末端设备的节能自动控制。当空调负荷发生变化时,通过采集一组参数值,经模糊运算,改变冷水机组工作状态、冷冻(温)水和冷却水流量和冷却塔风机的风量,确保冷水机组始终工作在效率最佳状态,使主机始终处于高转换效率的最佳运行工况。
Central air-conditioning system is one of the indispensable supporting facilities of modern large-scale buildings. The energy consumption is very large, accounting for about 50% of the total energy consumption of buildings. Is mainly introduced the use of building automation system (BAS) to achieve the end of the air-conditioning energy-saving automatic control. When the air conditioning load changes, by collecting a set of parameter values, the fuzzy operation, changing the chiller working conditions, freezing (warm water) and cooling water flow and cooling tower fan air flow to ensure that the chiller always work in the best efficiency , So that the host is always in high conversion efficiency of the best operating conditions.
