The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As shown in Figure 1, a kind of solar water supply, heating and air exchange system comprise the heat collector 1, domestic water water tank 11, gas fired-boiler 13, accumulation of energy water tank 5 and the solar chimney 2 that connect by pipeline mutually.Domestic water water tank inside is provided with coil pipe 17, lower coil pipe 16 and heater 15.Be provided with heat exchange coil 14 in the solar chimney 2.The upper end of last coil pipe 17 connects accumulation of energy water tank 5, and lower end second medium pump 6 of last coil pipe 17 connects accumulation of energy water tank 5.The upper end of lower coil pipe 16 connects accumulation of energy water tank 5 through plate type heat exchanger 8, and the lower end of lower coil pipe 16 connects accumulation of energy water tank 5 through the 3rd electric control valve 10, second electric control valve 9, plate type heat exchanger 8 and the 3rd medium pump 7.Heat collector 1 left end is connected in parallel between the 3rd electric control valve 10 that links to each other with the lower end and the plate type heat exchanger 8 of lower coil pipe 16, second electric control valve 9 through first medium pump 3.Upper end first electric control valve 4 of heat exchange coil 14 is in parallel with the upper end and the plate type heat exchanger 8 of the right-hand member of heat collector 1, lower coil pipe 16.The lower end of heat exchange coil 14 is connected in parallel between the 3rd electric control valve 10 and second electric control valve 9 that links to each other with the lower end and the plate type heat exchanger 8 of lower coil pipe 16.Accumulation of energy water tank 5 connects gas fired-boiler 13 by the 4th medium pump 12.Accumulation of energy water tank 5 also links to each other with heating system.

Solar chimney 2 is mainly formed flue by fiberglass, utilizes flange to connect between each joint.Medium in heat heating solar chimney 2 inner coil pipes that heat collector 1 produces has further improved the temperature of coil pipe ambient gas, forms convection current between the air, thereby air is flowed.
Three aspects that the acting body of solar chimney 2 is following now:
1. can change to by convection current the muddy air of indoor storage in evening with outdoor new wind indoorly in the morning, carry out the indoor wind that renews;
2. in summer, can utilize the wind that pulls out of solar chimney, make air form convection current, take away the heat in room, reduce temperature in the room;
3. in spring, autumn, the Sun Day irradiation is bigger, produces the heat height, needs to reduce temperature in the coil pipe by solar chimney 2, and then has also reduced the water temperature of water tank, thereby can prevent water in the water tank because of the overheated damage that causes equipment.
The course of work of the present utility model is: heat collector 1 begins to absorb solar heat, and when satisfied first medium pump, 3 entry conditions, the 3rd electric control valve 10 is opened, and first and second electric control valve 4,9 closures give the domestic water water tank 11 heating.Wherein, when solar energy is not enough, start heater 15 heating.When temperature in the domestic water water tank 11 reaches when setting value, the first, the 3rd electric control valve 4,10 closures, second electric control valve 9 is opened, simultaneously the 3rd medium pump 7, when first medium pump 3 reaches entry condition, give the accumulation of energy water tank 5 heating.Wherein, during summer, when water tank 5 temperature reach when setting value, second, third electric control valve 9,10 closures, first electric control valve 4 is opened, and heat is given to the built-in heat exchange coil 14 of solar chimney 2.During winter, accumulation of energy water tank 5 directly is connected (not shown) with heating system, keeps indoor uniform temperature, and solar energy is not enough to start gas fired-boiler 13, when reaching the 4th medium pump 12 entry conditions, and directly heat supply in accumulation of energy water tank 5.
During special circumstances, do not have at night under the sun situation,, preferentially use accumulation of energy water tank 5 heats when domestic water water tank 11 temperature are lower than setting value.And second medium pump 6 reaches entry condition, in the accumulation of energy water tank 5 hot water directly with domestic water water tank 11 on put coil pipe 17 generation heat exchanges.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
