A THERMODYNAMIC MODEL OF A SOLAR-ASSISTED HEAT-PUMP SYSTEM WITH ENERGY-STORAGE

In this study, a thermodynamic model of a solar assisted heat pump sys tem with energy storage was developed. The model consists of thermodyn amic correlations concerning the fundamental equipment in the system s uch as solar collector, energy storage tank, compressor, condenser and evaporator. Some model parameters of the system were calculated by us ing experimental results obtained from a pilot plant. Simulation studi es were performed to assess the importance of some design factors on t he system performance and economy. Copyright (C) 1996 Elsevier Science Ltd.
