A kind of high efficiency energy storage type Solar Heat Pump Heating System method of round-the-clock running
Technical field
The present invention relates to a kind of supplying hot water method, be a kind of by solar energy heat collection pipe thermal-arrest specifically, energy-accumulation material phase-change thermal storage, the heat pump heat supply method that oscillating heat pipe efficient heat transfer combines, belongs to field of solar energy utilization.
Background technology
Along with the development of society, the requirement that people promote quality of the life is more and more higher, and to the demand of hot water supply more and more strongly, the energy resource consumption of this respect accounts for the proportion building total energy consumption to be increased year by year for heating and life.Utilize regenerative resource, walking sustainable development path is one of effective way reducing building energy consumption." energy policy (2012) of China " white paper proposes to greatly develop new forms of energy and regenerative resource, points out " strengthen solar water heater and popularize dynamics, encourage central solar heating water, solar heating ".State Council has printed and distributed the notice that energy development " 12 " is planned, also points out " accelerate development construction integration solar application, encourage solar heating ".Solar energy is renewable and clean energy resource, China's solar energy resources aboundresources, has the regional annual radiant all quality of 2/3 to be greater than 5020MJ/m2, sunshine hour in year at more than 2200h.At present, solar water heater is rapidly developed, but because of the unstability of solar energy itself and intermittence, makes it as the main heating source of hot-water supply system, need to use together with ancillary heating equipment.Therefore, develop round-the-clock accumulating type solar heat pump to have important practical significance to energy-saving and cost-reducing.
Solar energy is renewable and clean energy resource, and Conventional cryogenic solar thermal collector heat-collecting temperature is at 55-75 DEG C, and have very high collecting efficiency, cost is relative moderate also, and low level solar thermal collector also helps and is combined with architecture-integral.Heat pump energy-conserving is with the obvious advantage, thus solar energy and heat pump united when running, and solar energy can provide the thermal source higher than environment temperature, after heat pump vaporizer side thermal source, can improve solar energy heating efficiency and hot pump performance simultaneously.But solar radiation by various complicated meteorology factor affect intensity time change, there is unstability and intermittence, thus cause solar energy heat pump system performance inconsistency large, in overcast and rainy and that the sunshine-duration is short winter, be difficult to realize round-the-clock supplying hot water.Once intensity of solar radiation lower than 250W/m2, heat-collecting temperature is also lower than ambient temperature, and evaporator with heat pump side can not get enough heats, and system cannot be run.Phase-changing energy-storing technology can solve solar energy supply and demand and not mate contradiction over time and space, namely can accumulation of energy when energy is many, discharges when needed, thus improves energy utilization rate.And utilizing latent heat accumulator, energy storage density is large, variations in temperature is little.Current accumulating type solar heat pump mostly is heat collector, storage heater, evaporimeter are arranged apart, system relative complex, manufacturing cost increases, and heat removal is as low order heat source for heat pump from storage heater to utilize heat-carrying agent, and water system has the danger of pipeline bursting by freezing in the winter time night.
