Description

Solar heating and hot water roof

The present invention relates to a kind of solar heating and hot water roof in the solar thermal utilization.

Existing a large amount of at present families uses the solar water heater as the hot feed source, but also there is not business-like solar energy roof, its main cause is, the solar vacuum tube roof involves great expense, its ratio of performance to price makes it can't commercial applications, and flat plat solar water heaters does not have frost resistance, can't use in winter, can not be used for heating.

Purpose of the present invention provides a kind of roof that both can be used as rainproof, snow defence, hail suppression and uses, and can collect a large amount of solar thermal energies again, is used to warm oneself and the solar heating and the hot water roof of hot feed.

For achieving the above object, the technical scheme that we take is: usefulness is compounded with ferrous metal paper tinsel face and the centre has the double-layer plastic plate of a plurality of junction plates to make the thermal-arrest core, and heat collector is made strip, and the rain-water drainage groove is installed between the heat collector; Water tank is installed in the highest point in house, and the secondary heat exchange device is installed in the water tank; Anti-icing fluid is housed in thermal-arrest/heat-exchange system.

Inner core plates

15 and 42 is connected together by the junction plate between them 57, be compounded with the metallic film of one deck black above the central layer 42, its manufacturing process be with plastic extruder with the plastic heat collection core is integrated extrude after the metal forming of compound immediately last layer black again, thermal-arrest core two ends is up and down formed header 40 and 48 by its termination sealing, and the two ends of header are shut; 43 is light-passing board, and it can use plastics, glass or tempered glass to make; Be filled with heat insulating material between warming plate 14 and the thermal-arrest core 15; 39 is the heat insulating material around the thermal-arrest core; Groove 12 and 38 is thermal-arrest core 15, warming plate 14, heat insulating material 39, the light-passing board 43 formation heat collector that is fixed together; The shape of lower accepting water groove 13 is as wavy watt,, it is installed in the bottom between adjacent two heat collectors, and link together with thermal-arrest tank 56,58, its function is: when upper accepting water groove 55 or thermal-arrest core 15 just in case when occurring leaking, the water that spills through its row to catch basin 37.18 is the back slope panel of building, and it and wall 17,29 connect together and constitute the back domatic of building; Heating heat-exchange device 27 and 28 is connected in parallel; Leader 31 is fixed on the front wall 30 of building; 21 is the floor of building; 36 for the pipe on the catch basin, it is discharged to the water in the catch basin in the water receiving bucket 35; Catch basin 37 connects together with wavy watt 13; Watertight shutter 49 upper ends are fixed on the tank shell, scribble marine glue between it and the shell, and its lower end and thermal-arrest tank 12 connect together, and its function is to prevent that rainwater from entering in the greenhouse; Running water pipe 51 is connected with automatic loading water self-closing valve 52, and connection cord 53 connects together valve body and float 54; Heat collector water inlet pipe 60 is connected with water inlet manifold 61.

Install heat collector of the present invention Chaoyang, when practical, toward the interior filling up water of water tank, fills it up with anti-icing fluid through expansion tank in heat exchanger and in the heat collector earlier.When illumination was arranged, sunlight saw through light-passing board, the ferrous metal paper tinsel extinction heat production on the thermal-arrest core, and the liquid in the thermal-arrest core is heated.When the water in native system is used for water tank heats, elder generation's shut off

valve

41,20,22,23, open valve 45 again, connect the pipeline pumping source, tubing pump work, the liquid in the thermal-arrest core manages 50 through in the Water collecting tube under pump function, and

pipe

11,10 enters the secondary heat exchange device, after by the secondary heat exchange device heat being passed to water in the water tank, again through manage 7, pipe 46, valve 45 enter tubing pump.Circulation so repeatedly, the water in the water tank promptly is heated.When native system is used for indoor heating, shut off valve 45, valve 20 and valve 22,

open valve

23,24,41, connect tubing pump 25 power supplys, liquid in the heating heat-exchange device 27 under pump pressure through manage 34,33, valve 41, after manage 50 in the Water collecting tube, pipe 11, pipe 10, valve 23, valve 24 enter tubing pump 25 by the thermal-arrest core, like this, the heat of the absorption of the liquid in the thermal-arrest core can reject heat to indoor by the heating heat-exchange device.If want with the hot water heating in the water tank 2, then shut off valve 45,41,23,

open valve

20,22,24, starting tubing pump 25, the water in the heating radiator 27 through manage 34,33,47, after valve 20, pipe 10 enter secondary heat exchange device 6 again through manage 7, valve 22, valve 24 enter pump 25.The heat energy of hot water can be discharged into indoor through the heating heat-exchange device in the water tank like this.By hot-water line 8, system can externally export hot water, when tap water cut-off, can open valve 19, and low water stage hot water is externally exported hot water by pipe 16, valve 19.

The metal forming of compound one deck black above the double-layer plastic thermal-arrest core of the present invention, can avoid ultraviolet direct irradiation central layer, thereby improve the ageing resistace of thermal-arrest core, prolong the application life of thermal-arrest core, the thermal-arrest core can improve the intensity and the heat insulating ability of thermal-arrest core towards the compound layer of metal paper tinsel of warming plate face.

The present invention adopts the secondary heat exchange system, and the energy transmission between the each several part is finished by anti-icing fluid fully, this just can the assurance system in the severe cold safe handling in winter, so because water and heating system in the hot water cylinder are isolated never fouling in the heating system fully.
