Therefore the air-conditioning market is facing the development of solving the challenges of new refrigerants and inverter driven strategy. Variable Refrigerant Volume (VRV) driver air-conditioning systems are widely accepted but still Suffers for the influence from piping length, ambient temperature and loading conditioning. In this study, the VRV air-conditioning system for an office building was investigated under different target evaporation temperature (TES) under cooling load condition. The target condensing temperature setting (TCS) has been studied under heating load condition as well. Field measurement has been conducted to survey the energy consumption of VRV system under different ambient condition. The results reveal that increase the TES under cooling mode and reduce the TCS under heating mode can reduce the energy consumption and enhance the stability of the VRV system. The piping length of refrigerant and the ambient temperature condition also play a very important role for energy consumption for VRV systems.
