Energy Measurement Method for VRV Air Conditioning Systems in Existing Commercial Buildings: A Case Study from Southeast University

Article Preview

Abstract:

Allowing users to track the household metering energy consumed by their central air conditioning system is an extremely effective strategy for saving energy in commercial buildings. This paper presents several methods of measuring the energy consumed by a central air conditioning system, such as using time-based and energy-based models. The accuracy and reliability of these models are also compared with each other. Finally, a novel energy metering method, the improved electricity-based model, for a variable refrigerant volume (VRV) air conditioning system in commercial buildings is proposed based on a case study of the Li Wenzheng building at Southeast University. Keywords: energy; measurement method; VRV air conditioning; existing commercial buildings
