The operation and control strategy in which heat pumps run in full capacity with the shortest runtime principally during the night proved correct even when compared with high performance heat pumps with variable frequency drive are used, with or without thermal storage. Simulation results, where precise equipment characteristic and yearly heating and cooling load are properly calculated using the Micro-HASP/TES for Windows and TES ECO, which were developed by HPTCJ, have shown that drastic reduction of energy consumption will result in by using VFD heat pumps and VWV pump systems for non-thermal storage systems but it is hardly less than those for thermal storage systems. In addition, in case for the thermal orage systems, VFD heat pump applications could rarely prove less energy compared to high performance constant speed eat pump applications.
