According to the method, the solar energy is used for supplying the hot water, or the evaporation temperature of the heat pump system is improved by utilizing the solar energy to supply the hot water, and therefore the heating efficiency of the heat pump system is improved, and the overall performance of the energy storage type solar heat pump heat water system is optimized.
Description
Technical field
The present invention relates to a kind of supplying hot water method, is a kind of by solar energy heat collection pipe thermal-arrest specifically, energy-accumulation material phase-change thermal storage, and 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 social development, it is more and more higher that people promote the requirement of quality of the life, and heating and life are more and more stronger to the demand of hot water supply, and the proportion that the energy resource consumption of this respect accounts for building total energy consumption is increasing year by year.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 the universal dynamics of solar water heater, encourage central solar heating water, solar heating ".State Council has printed and distributed the notice of energy development " 12 " planning, also points out " accelerate development construction integration solar application, encourage solar heating ".Solar energy is renewable and clean energy resource, and China's solar energy resources aboundresources has 2/3 regional annual radiant all quality to be greater than 5020MJ/m2, year sunshine hour more than 2200h.At present, solar water heater is rapidly developed, but because of unstability and the intermittence of solar energy itself, makes its main thermal source that should not serve as hot-water supply system, need to use together with auxiliary heating equipment.Therefore, developing round-the-clock accumulating type solar heat pump has important practical significance to energy-saving and cost-reducing.
Solar energy is renewable and clean energy resource, and conventional low-temperature solar energy heat collector heat-collecting temperature, at 55-75 DEG C, has very high collecting efficiency, and cost is also relatively cheap, and low level solar thermal collector also helps with architecture-integral and is combined.Heat pump energy-conserving is with the obvious advantage, thereby when solar energy and heat pump united operation, 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 be subject to various complicated meteorology factors affect intensity time change, there is unstability and intermittence, thereby cause solar energy heat pump system performance inconsistency large, in overcast and rainy and sunshine-duration in 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 moved.Phase-changing energy-storing technology can solve solar energy supply and demand and on time and space, not mate contradiction, namely can accumulation of energy in the time that energy is many, and discharge when needed, thereby improve energy utilization rate.And utilize latent heat accumulator, energy storage density is large, variations in temperature is little.It is arranged apart that current accumulating type solar heat pump mostly is heat collector, storage heater, evaporimeter, 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.
