DAIKIN,Osaka,Japan) Abstract It is one of the most important concerns for the researcher in the building energy saving fi eld in what kind of air conditioning should be used to save energy. Due to the high effi ciency of variable refrigerant fl ow (VRF) systems, the power simulation program of VRF systems is increasingly developing. In this paper, the power simulation program of a VRF system is developed with the evaporation temperature control module built in EnergyPlus based on BESP. The power consumption of a VRF system in actual offi ce rooms in common summer days is calculated, which is compared with the experimental results. The comparison result is fi nally used for the analysis and modifi cation of the module. Keywords Pyrology; VRF system; EnergyPlus;
