查询词典 centrifugal

States the characteristics of the condensing-temperature control in variable condenser water flow of central air-conditioning systems. Analyses the effects of variable condenser water flow on COP of centrifugal chillers. Indicates that although the negative effect is not negligibleit is less than the positive effect on pump's energy-saving and the condensing-temperature control is helpful to the resulting energy-saving for air-conditioning systems by combining with an example.

摘 要 论述了在集中空调冷却水变流量系统中冷凝温度控制法的特点；分析了冷却水变流量对离心式制冷机性能系数的影响；结合实例说明虽然冷却水变流量对于冷水机组制冷性能的负面影响不可忽略，但这一负面影响较对于水泵节能的正面影响要小，采用冷凝温度控制法对于空调系统综合节能是有益的。

According to the special requirements for centrifugal pump PIV measurement, a PIV testing platform was established to measure the instantaneous velocity in the double-channel pump with different impeller design, i.e., the double-channel impeller and the two-blade impeller, under different working conditions. The measured absolute velocity fields were transfered to relative velocity fields by specially developed code.
