Abstract:
A novel storage type solar heat pump water heater integrated with buildings is presented against the fact that ordinary solar water heater cannot work normally during the nights and consecutive rainy days.Based on oscillating heat pipe as a heat transfer medium,it transfers instantaneous solar energy or the energy stored by PCM in the collectors to the evaporator of heat pump system.Moreover,the system uses heat pump to heat water and provide domestic hot water.Then a suitable PCM is chosen and PCM’s storage characteristics are analyzed.The energy efficiency calculation of the storage type solar heat pump water heater integrated with buildings is carried out.The results show that the type solar heat pump water heater integrated with buildings is superior to a variety of water heaters on the market in energy efficiency and reducing emissions of pollutants.The proposal of integration with buildings will save space,reduce energy consumption and pollutant emissions under the conditions of intensive buildings and low share of unit residential solar radiation.It has a very broad application prospect.
