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

Abstract

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 heat cooling 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 a cooling 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.

Description

Technical field [0001] The invention involves a real -time monitoring technology of the cold load and cold volume consumption of the central air -conditioning system. Specifically, it refers to the real -time monitoring and cold measurement method and system of the cold load of the end of the air conditioner. Background technique [0002] Today, the rapid development of society and economy. As a large energy consumption household, the central air -conditioning system is generally used in various buildings. While improving people's production and living conditions, it also consumes a lot of electricity.Simple and practical, low -cost central air -conditioning system's air -conditioning terminal equipment Cold load in real -time monitoring and cold measurement methods and devices can provide technical support for centralized supervision, energy consumption monitoring, and billing of central air -conditioning systems.The monitoring platform provides basic data. [0003] The cold mea...
