The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
Refer to Fig. 1, a kind of solar airconditioning of its explanation one embodiment of the invention, comprises off-premises station and indoor set, and off-premises station and indoor set are integral types, and its outside is provided with casing; Adopt the structure air-conditioning volume of integral type little, convenient carrying and transfer, be applicable to the special occasions as machine room; The junction of off-premises station and indoor set is provided with a dividing plate, and dividing plate is divided into inner chamber and exocoel by casing.
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 9 from top to bottom.
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 efficiency of cold accumulating pond.Dividing plate is preferably aluminum material, and dividing plate is provided with several for arranging the eyelet of pipeline; Eyelet in the shape of a spiral and its aperture by centre, to both sides, increased gradually, 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 condenser heat radiation.
Cold accumulating pond 7 is rectangle housing, and its side near dividing plate is coated with adiabatic membrane, or preferably cold accumulating pond surrounding is all coated with adiabatic membrane, with prevent cold accumulating pond and next-door neighbour condenser or with external environment condition generation heat exchange, reduce the loss of refrigeration capacity of cold accumulating pond.Cold accumulating pond inside is provided with the cavity that holds refrigeration working medium; In cold accumulating pond 7, be full of the first refrigeration working medium, the first refrigeration working medium is mixture of ice and water or containing the mixture of ice and water of 0.1wt%～0.5wt% lithium chloride preferably.Cold accumulating pond 7 inside are vertically provided with several heat exchanger tubes 8, are preferably 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, and 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 HFC-134a preferably.In cold accumulating pond 7, be provided with and coil in heat exchanger tube 8 and at the copper pipe of the S-type structure of vertical direction; Copper pipe one end connects direct current compressor 3, and the other end connects expansion valve 9; Adopting S type structure is contact area and the time of contact that increases the first refrigeration working medium in the interior cold-producing medium circulating of copper pipe and cold accumulating pond.
Solar airconditioning also comprises solar thermal collector and transducer, and their effect is that luminous energy is finally converted into electric energy.Solar thermal collector connects transducer, and transducer connects respectively energy storage pond 4 and electric cabinet 6; Electric cabinet 6 is for controlling the circuit operation of complete machine, and it is connected with the second blower fan 5 with energy storage pond 4, direct current compressor 3, the first blower fan 2 respectively.Solar airconditioning is also provided with driven compressor module; By driver module, can make the electric energy that is converted drive blower fan and compressor, therefore in fact driven compressor module can be controlled direct current compressor and 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 in condenser 1 outside, be provided with a dirt filtrating screen.Dirt filtrating screen is aluminum, rapid heat dissipation, and thermal resistance is little, can not affect the heat exchange property of condenser.In order to increase the heat dispersion of condenser, preferably on the fin of condenser, be provided with several micropores, in the shape of a spiral, its pore size is preferably 0.5mm～2mm to micropore, and this design is to improve its heat exchange property by increasing the specific area of fin.
The operation principle of solar airconditioning is: the electric energy obtaining through device of solar generating drives direct current compressor and blower fan, and a part of electric energy can be collected in energy storage pond simultaneously, for unglazed according to time air-conditioning normal operation.
Outdoor circulation: cold-producing medium compresses from direct current compressor 3 gas that becomes HTHP, through copper pipe, flow into condenser 1, by the first blower fan 2 and outdoor air, carry out exchange heat, cold-producing medium becomes the liquid of HTHP, by copper pipe, pass through expansion valve 9 and carry out throttling, become the liquid of low-temp low-pressure, the first refrigeration working medium generation heat exchange in cold accumulating pond 7 interior S type copper pipe and pond, the first refrigeration working medium is collected cold and is carried out cold-storage, and the gas that cold-producing medium becomes low-temp low-pressure enters direct current compressor 3 compression cycle again.
Indoor circulation: heat exchange is occurred to for Indoor Thermal air and heat exchanger tube 8 by the second blower fan 5, the second refrigeration working medium that heat exchanger tube is 8 li becomes gas and rises to heat exchanger tube 8 tops, it carries out exchange heat with cold accumulating pond 7 again, the second refrigeration working medium is cooled to the liquid return that falls and carries out heat exchange again in heat exchanger tube 8 bottoms of cold accumulating pond 7 outsides, with this, circulates Indoor Thermal air is lowered the temperature.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in description and embodiment, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend of describing.
