Central heating method and system using solar energy and heat pump to replace part of traditional heat source

The technical scheme of the invention uses solar energy and heat pump to replace the implementation system of central heating of part of traditional heat source, including: Solar Collector, energy storage circulating water system, low-temperature water storage pool, low-temperature water supply system of water storage pool, energy transmission circulating water network, heat pump heating system, secondary circulating water network, Primary Circulating Water Network, heat exchanger; the design method can make small-scale solar collectors collect more solar energy, the heat is stored in the low-temperature storage pool, the heat in the pool is heated by the heat pump, and the water in the pool is reheated by the solar energy during the day All heat exchange stations are equipped with solar-heat pump, the system can get a lot of heat, and a large number of replacement of raw coal, raw coal replacement volume of about 30%-50% or more. It not only saves a lot of fuel, but also greatly reduces the emission of carbon dioxide and other flue gas and ash emissions, both environmental protection and energy saving.
