The specific embodiment
In order to demonstrate fully the synthesis energy saving operational effect of native system, below we can in conjunction with after accompanying drawing analyze the operation embodiment of native system in actual application.
Patent of the present invention designs substantially: the whole system device is made up of four parts, mainly comprises solar heat-collection and heat-accumulation circulation assembly, heating heat exchange circulation assembly, two-way branch heat pump cycle assembly and ground source heat exchange circulation assembly.
Solar heat-collection and heat-accumulation circulation assembly mainly comprises auxiliary valve members such as solar thermal collector assembly, solar energy heating circulating pump, hot water storage tank and automatic exhaust steam valve, and the heating agent transfer pipeline is configured in (as Fig. 1) between heat collector and the hot water storage tank.Because native system mainly is applicable to the heating area of weather cold, so the solar thermal collector in the system should be selected the not vacuum tube collector and the heat pipe vacuum tube collector of easy freezing for use.Also to assemble necessary overflow passage, discharge pipe line and system water supplement pipeline on the hot water storage tank, also will be furnished with necessary valve member on it.
Heating heat exchange circulation comprises magnetic valve, heating circulating pump, terminal heating equipment and other the auxiliary valve member on coil exchanger, direct heat transfer and the indirect heat exchange pipeline that is positioned at water tank inside.Circulation line is configured between each parts.Because the heat energy grade of solar energy and soil source is not high, so need coupling floor heating coil pipe or the so terminal heating equipment of fan coil.The heating agent operating temperature that they require is about in the of 50 ℃.In order to strengthen the heat exchange between direct heat transfer coil pipe and the accumulation of heat heating agent, heat exchange coil is assembled in the centre position of hot water storage tank, and coil pipe is laterally placed and be relative with the return pipe outlet of solar energy heating circulation and plate type heat exchanger I water side heat exchange circulation.Any one all can strengthen the pipe outside heat exchange of coil heat exchanger above-mentioned like this two loop starts.
Two-way branch heat pump cycle assembly comprises compressor, four-way change-over valve, two-way expansion valve, plate type heat exchanger I, plate type heat exchanger II, plate type heat exchanger III circulate in addition check valve I and circulation check valve II.Circulating condensing pipeline section and evaporation pipeline section connect into a total system with each parts.Wherein three plate type heat exchangers are the circular array connection.Plate type heat exchanger I is inner in circulation all the time, and plate type heat exchanger II and plate type heat exchanger III constitute the reverse parallel connection relation by the opposite circulation check valve of direction.Though promptly two heat exchangers are in parallel, when moving in system, wherein have only all the time one with circulation UNICOM.When the four-way change-over valve forward connected, plate type heat exchanger I became the condenser of vapor-compression refrigerant cycle, and heat release in heat accumulation hot water; To opening, plate type heat exchanger II inserts the evaporimeter that the circulatory system becomes vapor-compression refrigerant cycle to circulation check valve I along circular flow, and from source, ground heat exchange circulation heat absorption.Forward and the circular flow of check valve II circulate simultaneously to opposite, cause plate type heat exchanger III and not conducting of cooling cycle system.After the four-way change-over valve commutation, plate type heat exchanger I becomes the evaporimeter of vapor-compression refrigerant cycle, and absorbs heat from heat accumulation hot water; Circulation check valve I and circular flow cause plate type heat exchanger II and circulate not conducting to opposite; The suitable circular flow of the check valve II that circulates simultaneously is to opening, and making plate type heat exchanger III insert vapor-compression refrigerant cycle becomes condenser, and to indirect heating heat exchange circulation heat release.
Ground source heat exchange circulation assembly comprise source, ground circulating pump, the source heat exchange coil and with the plate type heat exchanger II of two-way branch heat pump cycle indirect heat exchange, circulation line that is attached thereto in addition and the relevant valve member of assisting.The source heat exchange continuous operation meeting that circulates in ground is transported to the heat energy in the soil source in the heat pump cycle and further passes to thus heat storage medium in the hot water storage tank endlessly.The closed operation in source, ground heat exchange circulation line of heat-carrying medium can not pollute the soil below the face of land.Prevent that simultaneously underground water from entering circulation line and damaging heat exchanger.
Heat pump cycle is to circulate by the plate type heat exchanger I water side that a heat exchange circulating pump and relevant valve member are formed to realize with heat exchange between the hot water storage tank in addition.
This system mainly is the building and heating heat supply that is applied to winter.The solar energy abundance time, the solar energy heating circulation can begin temperature difference recurrent state automatically by day.The start and stop that are the solar energy circulating pump are controlled by the outlet heat medium temperature of solar thermal collector and the temperature difference of the hot water temperature in the water tank.When the temperature difference sets value greater than one, the solar energy circulating pump starts, the hot water that has fully absorbed solar energy is pushed into water tank from heat collector, when in case the temperature difference falls back to a lower setting value again, the solar energy circulating pump just stops, and is transported to the heat-accumulating process that low-temperature water heating in the solar thermal collector begins a new round.Go round and begin again, solar thermal collector can be constantly with delivery in hot water storage tank.Because the indoor heating thermic load on daytime is smaller, and according to design, for the heat that guarantees the heat collector in the effective period at sunshine on daytime can satisfy the building and heating demand of longer time, the collector power of heat collector is wanted obviously greater than the building instantaneous heating thermic load on daytime.So by day, in system's heating, heat energy still has surplus in the hot water storage tank, so water temperature can constantly rise.When heat accumulating water temperature rose to certain temperature, heating heat exchange circulation switched to the direct heat transfer recurrent state, and heating hot water is transported in the interior direct heat transfer coil pipe of hot water storage tank, by tube wall and heat accumulation hot water heat exchange.
When running into overcast and rainy or the dusk time-division, when illumination is not enough, when if the heat of the solar energy that stores in the hot water storage tank still can not satisfy the heating demand at night on the same day, earth source heat pump accumulation of heat pattern starts, two-way branch heat pump cycle switches to earth source heat pump recurrent state (seeing accompanying drawing 1), side by side source circulating pump and plate type heat exchanger I water side circulating pump start, and soil source heat energy can be transported in the heat accumulation hot water to replenish the thermic load of deficiency on the same day endlessly by heat pump cycle like this.After heat energy replenished and puts in place, heat pump cycle stopped.
There are not solar energy or soil heat source to replenish under the not enough situation at night, constantly carry in the process of heat energy in heating heat exchange circulation to indoor heating end-equipment, heat accumulating water temperature constantly descends, in case when dropping to it and can not guarantee the work the accepted water temperature of heating end-equipment, the heating heat-exchange circulation just switches to the indirect heat exchange pattern, two-way branch heat pump cycle switches to heat supply heat pump cycle pattern (seeing accompanying drawing 2) simultaneously, the heat supply heat pump cycle continues heat absorption and the condenser by this circulation from the lower heat accumulation hot water of temperature like this, be plate type heat exchanger III, thereby discharge the job requirement that high temperature heat continues to satisfy the heating end-equipment to indirect heating heat exchange circulation.
After recovering sunshine in second day, system begins to experience a new heating operation cycle again.
Along with the thermic load of the variation building and heating of external environment is also changing.In the transition season, the heating thermic load is far smaller than the solar energy odd-numbered day heat-collecting capacity of system's design, all can have the heat energy surplus every day in the hot water storage tank like this, can guarantee that the circulation of whole day heating heat-exchange all is operated in direct heating heat exchange pattern, simultaneously in case run into the heat energy of short-term and replenish when not enough, the heat energy of surplus can prolong the heating heat exchange and circulate in direct heating heat exchange mode of operation under the high heat accumulating water temperature condition.
