摘要/Abstract

摘要： 由于多联机系统多末端的特征,对其各末端实现冷热量的分户计量技术对建筑能源管理、公平计费等方面有重要意义。然而,目前难以通过内置传感器实现低成本、高精度的性能计量。针对现有分户计量研究现状,提出了三种实现多联机分户计量的途径,并以制冷工况为例,通过水冷多联机实验台的实验分析,探讨所提方法的精度和适用性。

Abstract: Due to the multi-terminal characteristics of the VRF system, the individual performance metering technology for each terminal is of great significance for building energy management and fair billing, etc. However, it is currently difficult to achieve a low-cost, high-precision performance measurement method with built-in sensors. This paper investigates related existing research, and proposed three methods to realize individual performance metering. In cooling conditions, the measurement method is validated and discussed on the water-cooled VRF test bench. In this way, the accuracy and applicability of the proposed methods are analyzed.
