The invention has the advantage of finding a matched intermediate heat storage facility for the combination of solar energy and a heat pump. The embodiment is given by combining with a figure in the specification.

Description

Solar heat pump heat and heat water supplying system well regenerative process and system
Technical field
The present invention relates to solar heat pump heat and heat water supplying system well regenerative process and system.
Background technology
Heat pump heating system utilizes solar collector to make the Energy Efficiency Ratio that low-temperature heat source can improve source pump.But heat load and sunlight intensity are often asynchronous.Daytime, solar irradiation was strong, but heat load is low, and solar thermal energy is rich but can not effectively store; The sleet sky and night the heat load height, can not utilize but at this moment there is enough solar energy.
Summary of the invention
The objective of the invention is to provide solar heat pump heat and heat water supplying system well regenerative process and system.
The present invention solves the method that its technical problem is taked: calculate needed solar energy heat collector area according to the heat and heat water supplying load, with the thermal energy storage of solar energy heat collector output in well shape artificial water, well shape artificial water comprise the circulation well of family expenses well, earth source heat pump and more than two mouthfuls on ground or the well shape thing of underground intercommunication, but do not comprise with rice be its degree of depth of measurement unit with the ratio of sectional area less than 3.1 water body and the water body that opens wide, well shape artificial water is called for short the accumulation of heat well.Source pump is that thermal source provides heat energy to the heat and heat water supplying facility with accumulation of heat well well water.
The present invention solves the technical scheme that its technical problem is taked according to said method: with solar energy heat collector, source pump and a well heat-storage solar-heat of accumulation of heat well construction pump heat and heat water supplying system.The accumulation of heat well well water that is connected with the evaporimeter or the condenser heat exchange of source pump is connected with the solar heat collector heat exchange.
Beneficial effect of the present invention comprises: combine the middle accumulation of heat facility that finds a coupling with heat pump for solar energy.Utilize all right and soil heat exchange of accumulation of heat well.
Description of drawings
Further specify below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of a well heat-storage solar-heat pump heat and heat water supplying system.
1. heat collectors among the figure; 2. source pump; 3. accumulation of heat well; 4. constant-temperature evaporation device; 5. cryogenic vaporizer; 6. low temperature chamber; 7. container freezes; 8. boiler.
The specific embodiment
Fig. 1 embodiment, form a well heat-storage solar-heat pump heat and heat water supplying system with solar energy heat collector 1, source pump 2 and accumulation of heat well 3, source pump 2 contains the constant-temperature evaporation device 4 and the cryogenic vaporizer 5 that can switch, and constant-temperature evaporation device 4 is connected with the 3 well water heat exchange of accumulation of heat well.Cryogenic vaporizer 5 is connected with low temperature chamber 6 heat exchange that are separated by heat-insulating material of setting in the accumulation of heat well 3.Low temperature chamber 6 fills refrigerant, and inside is provided with the container 7 that freezes.The load of source pump 2 also comprises the boiler 8 of a built-in heat exchange coil.Accumulation of heat well 3 well water that are connected with constant-temperature evaporation device 4 heat exchange of source pump 2 have the heat exchange interface with solar collector 1.
During source pump 2 operations, from accumulation of heat well 3 well water, obtain heat energy and the well water temperature is descended by constant-temperature evaporation device 4.Heat collector 1 often replenishes heat energy to accumulation of heat well 3.Do not have the solar time when several days, accumulation of heat well 3 still can be kept operation by replenishing heat energy with soil heat exchange.Replenish deficiency as soil heat exchange and then start phase transformation heat production mechanism: source pump 2 is switched with cryogenic vaporizer 5.It is subzero that cryogenic vaporizer 5 drops to the temperature in the low temperature chamber 6, the container 7 that freezes frozen emit heat of transformation supply heat pump.Opening well lid removes ice cube in the container 7 that freezes and pours into water again and can continue heat-obtaining again.
By the time weather is fine makes the well water temperature recovery with solar energy, and source pump 2 is switched back constant-temperature evaporation device 4 again.Also can be provided with in the low temperature chamber 6 and the extraneous heat exchange interface that comprises solar collector 1.
