Air source heat pump energy storage heating system for smart building

For energy storage heating in the smart building, this paper puts forward a new kind of smart building energy storage system. Air heat pump energy storage heating system consists of energy storage heating platform and the control strategy of energy storage heating. First of all, this paper build energy storage heating platform. The system uses air source heat pump as an energy conversion device converting the energy power to heat energy in the smart building; Using energy storage tank as energy storage container, this paper store the thermal energy in the storage containers; The system uses a fan as energy release device. Secondly, energy storage heating control strategy is derived. According to the law of conservation of energy, air source heat pump heating temperature function is established, the function constitutes energy storage method in the daytime; This paper establish the relationship between the outdoor temperature and the energy storage temperature and propose the energy storage method in the night. Finally, from two aspects of conversion efficiency and energy consumption, this paper compares air source heat pump energy storage heating system with the battery energy storage system. The results illustrate that it is less than 1.27% of battery energy storage system in terms of the energy conversion efficiency, but reduces by 58.44% in the aspect of energy consumption.
