《多联机中央空调分户计量(实时分摊)系统分户计量偏差测试方法》标准解读

Interpretation of Test method for apportionment deviation of household metering system for cold and hot consumption of multi-unit central air-condition

多联机中央空调准确公平的分户计量是降低大型建筑能耗的有力保障。现阶段行业内存在多种电量实时分摊算法,但没有统一科学的测试方法对分摊结果的偏差进行评估,无法衡量系统分摊的准确性、公平性。《多联机中央空调分户计量(实时分摊)系统分户计量偏差测试方法》提出了合理可行的三种测试场景,对冷热量分摊偏差给出了明确的计算方法,为衡量系统的分摊准确性提供依据,促进行业技术发展。

The accurate and fair household metering function of multi-unit central air-condition is a powerful guarantee for reducing energy consumption of large buildings.At present,there are many kinds of real-time power allocation algorithms in the industry,but there is no unified scientific test method to evaluate the deviation of the allocation results,and it is impossible to measure the accuracy and fairness of the system allocation.T/CAS 702-2023,Test method for apportionment deviation of household metering system for cold and hot consumption of multiunit central air-condition,puts forward three reasonable and feasible test scenarios,gives a clear calculation method for the allocation deviation of heating and cooling capacity,and provides a basis for measuring the system’s allocation accuracy to promote the technological development of the industry.
