摘要:

基于制冷机房系统评价分级需求,提出了系统冷负荷为1 583 kW(450 rt)和7 034 kW(2 000 rt)的大小2个系统模型。明确了模型中冷源系统形式,以及冷水机组、水泵、冷却塔各设备参数中影响系统能效的参数选型原则,包括冷水机组的COP、水阻力、水温、机型,水泵的扬程、效率,冷却塔的能效、变频、冷幅、变流量等的要求,确保了模型的合理建立。

Abstract:

Based on the energy efficiency grading assessment requirements of the chiller plant system, puts forward two system models with cooling load of 1 583 kW (450 rt) and 7 034 kW (2 000 rt). Defines the form of cold source system in the model and the selection principle of parameters affecting system energy efficiency in various equipment parameters of chillers, water pumps and cooling towers, which includes the requirements of the COP, water resistance, water temperature and type of chillers, the head and efficiency of water pumps, the energy efficiency, frequency conversion, cooling approach, variable flow rate of cooling towers, and so on, ensuring the reasonable establishment of the model.
