摘　　要： 针对风机盘管集中空调系统,从风机盘管换热平衡的角度,提出采用风侧焓差法对风机盘管冷/热量进行计量的设想,同时对该方法进行了实验研究和误差分析,并且介绍了焓差法冷量计量装置的特点,得出的结论是采用风侧焓差法计量可以使计量误差降低到20％以下,从而满足工程中对冷量计量的需要。风侧焓差法冷量计量方法的出现有助于促进国内冷量计量收费工作的推广开展。 For fan-coil central air conditioning systems, the assumption of using air-side enthalpy difference method to meter the cooling/heating capacity of fan coil from the aspect of the unit's heat balance was put forward in this paper, at the same time, the experimental research and error analysis for the method were given, and the features of cooling metering device based on the enthalpy difference method was presented also, it was concluded that this metering method can reduce metering error to less than 20% and meet the requirement of engineering. The appearance of the air-side enthalpy difference metering method helps to boost the progress of the cooling metering and charging work in our country.
