Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art's referenceDescription word can be implemented according to this.
Refer to Fig. 1, its explanation one embodiment of the invention a kind of solar airconditioning, comprise off-premises station andIndoor set, off-premises station and indoor set are integral types, its outside is provided with casing; Adopt the structure of integral typeAir-conditioning volume is little, and convenient carrying and transfer, be applicable to the special occasions as machine room; Off-premises station and indoorThe junction of machine is provided with a dividing plate, and casing is divided into inner chamber and exocoel by dividing plate.
Exocoel is respectively equipped with condenser 1, the first blower fan 2, direct current compressor 3 and energy storage pond 4 from top to bottom;Inner chamber is respectively equipped with the second blower fan 5, electric cabinet 6, cold accumulating pond 7, heat exchanger tube 8 and expansion valve from top to bottom9。
Dividing plate one side contacts condenser 1, opposite side and cold accumulating pond 7 are possessed at least air line distance of 2mm;This design is to prevent that condenser is by dividing plate and cold accumulating pond generation heat exchange, thereby affects the cold-storage of cold accumulating pondEfficiency. Dividing plate is preferably aluminum material, and dividing plate is provided with several for arranging the eyelet of pipeline; EyeletIn the shape of a spiral and its aperture increased gradually to both sides by centre, the pore size of eyelet is 5mm～20mm,This structural design has increased the specific area of the aluminum spacer plate contacting with condenser, thereby contributes to condenserHeat radiation.
Cold accumulating pond 7 is rectangle housing, and its side near dividing plate is coated with adiabatic membrane, or cold-storage preferablyPond surrounding is all coated with adiabatic membrane, to prevent cold accumulating pond and next-door neighbour's condenser or with external environment condition, heat to occurExchange, the loss of refrigeration capacity of minimizing cold accumulating pond. Cold accumulating pond inside is provided with the cavity that holds refrigeration working medium; Cold-storageIn pond 7, be full of the first refrigeration working medium, the first refrigeration working medium preferably mixture of ice and water or containing 0.1wt%～The mixture of ice and water of 0.5wt% lithium chloride. Cold accumulating pond 7 inside are vertically provided with several heat exchanger tubes 8, preferablyBe provided with 4～16 heat exchanger tubes. Heat exchanger tube 8 lower ends are stretched out cold accumulating pond 7 bottoms and are contacted with extraneous air,Heat exchanger tube 8 surroundings are airtight, inner hollow, and inside is provided with the second refrigeration working medium, and the second refrigeration working medium is excellentChoosing is HFC-134a. In cold accumulating pond 7, be provided with and coil in heat exchanger tube 8 and in the S-type structure of vertical directionCopper pipe; Copper pipe one end connects direct current compressor 3, and the other end connects expansion valve 9; Adopting S type structure is to increaseAdd contact area and the time of contact of the first refrigeration working medium in the interior cold-producing medium circulating of copper pipe and cold accumulating pond.
Condenser 1 one end connects direct current compressor 3, and the other end connects expansion valve 9; Condenser 1, expansionValve 9, cold accumulating pond 7 and direct current compressor 3 four form a closure for refrigerant circulation circulation and returnRoad.
Solar airconditioning also comprises solar thermal collector and transducer, and their effect is that luminous energy is finally turnedTurn to electric energy.

Solar airconditioning is also provided with driven compressor module; By driving mouldPiece can make the electric energy being converted drive blower fan and compressor, and therefore in fact driven compressor module can be controlledDirect current compressor processed is only having just startup work under illumination condition.
In order to prevent that the accumulation of a large amount of dusts from affecting the heat transfer effect of condenser 1, preferably outside condenser 1Portion is provided with a dirt filtrating screen. Dirt filtrating screen is aluminum, rapid heat dissipation, and thermal resistance is little, can not affect condenserHeat exchange property. In order to increase the heat dispersion of condenser, preferably on the fin of condenser, be provided with that several are micro-Hole, in the shape of a spiral, its pore size is preferably 0.5mm～2mm to micropore, and this design is by increasing finSpecific area improve its heat exchange property.
The operation principle of solar airconditioning is: the electric energy obtaining through device of solar generating drives direct current compressionMachine and blower fan, simultaneously a part of electric energy can be collected in energy storage pond, for unglazed according to time air-conditioning normal operation.
Outdoor circulation: cold-producing medium compresses from direct current compressor 3 gas that becomes HTHP, flows through copper pipeEnter condenser 1, carry out exchange heat by the first blower fan 2 and outdoor air, it is high that cold-producing medium becomes high temperatureThe liquid of pressing, passes through expansion valve 9 by copper pipe and carries out throttling, becomes the liquid of low-temp low-pressure, through cold-storageThe first refrigeration working medium generation heat exchange in pond 7 interior S type copper pipe and pond, the first refrigeration working medium is collected cold and is enteredRow cold-storage, the gas that cold-producing medium becomes low-temp low-pressure enters direct current compressor 3 compression cycle again.
Indoor circulation: Indoor Thermal air and heat exchanger tube 8 heat exchange are occurred to, heat exchange by the second blower fan 5Manage second refrigeration working medium of 8 li and become gas and rise to heat exchanger tube 8 tops, it carries out with cold accumulating pond 7 againExchange heat, the second refrigeration working medium is cooled to liquid and falls return in heat exchanger tube 8 bottoms of cold accumulating pond 7 outsidesCarry out heat exchange again, circulate Indoor Thermal air is lowered the temperature with this.
Although embodiment of the present invention are open as above, it is not restricted to description and enforcement sideListed utilization in formula, it can be applied to various applicable the field of the invention completely, for being familiar with abilityThe personnel in territory, can easily realize other amendment, therefore do not deviate from claim and etc. homotypeEnclose under limited universal, the present invention is not limited to specific details and illustrates here and the figure describingExample.
