Analysis Of Energy Use In Water Source VRF System And Evaluation For Its Use In China

Water source VRF heat pump air-conditioning system is a new energy saving system which comes into the market since 2005. It gathers the advantages of both the frequency conversion air-conditioning system and water source ( loop ) heat pump system and has its unique predominance than the conventional system. Presently,it has'nt been researched much or deeply. In order to know the energy saving sysem well further , we advance the dissertation to guide the use of the system in our country.According to , using EnergyPlus software , we simulated the dynamic energy consumption of office buildings in six cities in this dissertation, and analyzed and compared the difference between the WSVRF system and the conventional system. Calculate the SEER and HSPF values of WSVRF units in six cities and compare the results with those of the conventional air-conditioning units, by which we can afford the SEER index and HSPF index of WSVRF units in six cities; Additionally, the electricity consumption(EC) index A,primary energy consumption(PEC) index A ( W/m2 ) and EC index B and PEC index B(kW·h/m2) of WSVRF units are achieved, which can afford an index reference to evaluate the annual energy consumption of WSVRF units applying in energy saving office in different areas; Summarize two running principle and finally achieved its preliminary evaluation for use in China.
