Real-time monitoring and cooling capacity metering method and system for cooling loads of air conditioner end equipment

The invention provides a real-time monitoring and cooling capacity metering method and a system for cooling loads of air conditioner end equipment. The method comprises the steps: measuring the transient total cooling capacity of a single-function building cooling source or the transient total cooling capacity of different functional areas of comprehensive buildings and computing the sensible heatcooling loads of an air conditioner end for measuring and computing the total heat cooling loads of the air conditioner end. The system comprises a local data center, an end intelligent node device and a front-end intelligent node device, wherein a data converting module is arranged between the local data center and the front-end intelligent node device; the front-end intelligent node device is acooling source intelligent node device or a pipe network intelligent node device; the end intelligent node device is arranged on air conditioner end equipment in an air conditioner system; the cooling source intelligent node device is arranged on the single-function building cooling source and the pipe network intelligent node device is arranged on a freezing water pipe network of all the functional areas of the comprehensive buildings. The invention has the advantages of lower cost, convenient construction, simple measurement and the like, is suitable for real-time monitoring and cooling capacity metering of the cooling loads of all kinds of buildings of air conditioner end equipment and is also suitable for new buildings.
