Comparison Study of Energy Ratio of ORC Compound With Vapor Compression Heat Pump System Using Different Working Fluid

The working characteristic of organic Rankin cycle(ORC) compound with vapor compression heat pump system was described in this paper,and the calculation method was established.The working performance under both cooling and heating condition was researched using different working fluid,and the suitable working fluid was obtained.This work can offer the theoretical direction for designing the ORC compound with vapor compression heat pump system.
