根据ASHRAE 90.1-2010规定的离心式冷水机组在非AHRI标准工况下COP和NPLV的换算公式,推导了从国标工况下COP值换算到非国标工况下COP值的计算公式,不仅获得在常规设计工况下(32℃/37℃,7℃/12℃)达到节能产品要求的离心式冷水机组COP的限定值,而且提供一种在非国标工况下判定离心式冷水机组是节能产品的方法,即在工程中实测离心式冷水机组的COP,换算到国标工况下的COP值,与节能产品的COP限定值进行比较。
According to the conversion formula of COP and NPLV of centrifugal chillers under ASHRAE 90.1-2010 under non-AHRI standard conditions, the formula for calculating the COP from conversion of COP values under national standard conditions to non-GB conditions is deduced. Conventional design conditions (32 ℃ / 37 ℃, 7 ℃ / 12 ℃) to meet the requirements of energy-saving centrifugal chillers COP the limited value, but also to provide a non-GB conditions to determine the centrifugal chillers is energy-saving products Method, that is measured in the project Centrifugal Chiller COP, converted to the COP under the national conditions COP values, energy-saving products with the COP limit value for comparison.
