Application of VRV Air-Conditioning System Heat Recovery Series in Construction Inner Zone and Analysis of Its Energy-saving

In order to reduce energy consumption of air-conditioning system,under the condition of supplying cold load in winter for the rooms in building's inner zone,VRV air-conditioning system heat recovery series of variable frequency technology was used to realize the heat and cold energy's best balance in buildings and achieve the effect of energy-saving by taking full advantage of the indoor heat and cold energy.Through analyzing the structures and running principles of this VRV air-conditioning system and the specific projects,its application in building's inner zone and energy-saving characteristic were discussed.
