Abstract

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.

Key words: Variable refrigerant flow system, Individual measurement, Performance measurement
