RESEARCH ON IMPROVING THE ENERGY INDEPENDENCE RATE OF HOMES EQUIPPED WITH PVT AND HEAT PUMP HEATING / COOLING / VENTILATION / WATER HEATING SYSTEMS

In recent years, there has been a demand for energy conservation in housing. The authors study PVT/heat pump heating/cooling/ventilation/water heating system to improve the energy independence rate in winter. They conducted case studies to verify the results of the analysis, which suggested that the energy independence rate can be improved by raising the temperature setting during the daytime and using PV power generation to store heat under the floor. The analysis results showed that appropriate heat pump heating operation and under-floor heat storage design tended to improve the energy independence rate and realize a comfortable thermal environment.
