Study On The Solar-Heat Pump System For Heating System Integration

This paper introduced a new heating way of using solar technology combined with the heat pump technology, considering abundant solar energy resources in China, in view of present global energy nervousness and the enormous energy consume of the northern city heating problems in winter.We find that using solar heating can basically satisfy the room needs hot through testing change of temperature and the solar radiation. But to coping the heating problems in extremely bad weather, because solar exist dispersion, randomness and intermittent problems, we coupling air source heat pump and the water source heat pump in solar energy heat pump heating system. and plus auxiliary heat source lows electricity in system. At the same time, we introduced in solar energy heat pump system with a patent type heat pump - the refrigeration cycle with ejector device, and put forward a novel solar auxiliary heat supply system with ejector with its version.In multi-heat-source solar energy heat pump heating system, The ambient temperature has very big effect on heating output of air source heat pump. Therefore, this paper using MATLAB software simulates how imported temperature influence the heating output of air source heat pump. Water Source Heat Pump(WSHP) use regenerator water as low-temperature heat source, so the temperature of regenerator water has big effect on heating output of WSHP, The paper also analyzed how the import water temperature influence WSHP. According to the calculation results we found that combine the solar technology and the heat pump technology can improve the utilization rate of solar energy heat pump system with the efficiency.Results show that solar energy heat pump system can solve the heating problems all-weather after optimized the integration and automatic control of system. Utilize solar energy resources are very favorable and necessary. Solar energy heat pump heating system is especially suitable for ordinary people and towns, villages users employ the non-concentration of heat-supply way. Not only effective utilization of energy, but also response the call of sustainable development has been advocated of our country.
