Description of drawings
Accompanying drawing 1 is a schematic diagram of the present invention.
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Referring to shown in Figure 1, a kind of solar energy system, mainly comprise solar thermal collector 1, the solar water container 6 that links to each other with solar thermal collector 1, lithium bromide cooling-water machine group 3, the operating water tank 7 that is used for cooling or heat supply, indoor fan coil system 4, indoor ground heating system 5, wind cooling cold and hot water unit 2, domestic water water tank 9, be used to be communicated with the intake line 11 and the output pipe 12 of solar water container 6 and operating water tank 7, stored the hot water of output from solar thermal collector 1 in the solar water container 6, consume after heat becomes cold water at hot water, cold water can re-enter in the solar thermal collector 1 and heat, solar thermal collector 1 can be converted into the radiant energy of the sun heat energy and add hot water, has then formed a closed circuit that utilizes solar energy that hot water is provided between solar water container 6 and the solar thermal collector 1; Lithium bromide cooling-water machine group 3 is connected between solar water container 6 and the operating water tank 7, lithium bromide cooling-water machine group 3 can absorb the heat of the water in the solar water container 6 so that the water in the operating water tank 7 is freezed, wind cooling cold and hot water unit 2 also can freeze to the water in the operating water tank 7, therefore select to adopt lithium bromide cooling-water machine group 3 or adopt wind cooling cold and hot water unit 2 to freeze by the water temperature in the solar water container 6, be connected with indoor fan coil system 4 on the operating water tank 7, can provide the cooling air to the room; Wind cooling cold and hot water unit 2 also can heat the water in the operating water tank 7, operating water tank 7 can provide hot-air to the room by indoor fan coil system 4 like this, also be connected with indoor ground heating system 5 on the operating water tank 7, to the indoor underground heat that supplies, can heat supply except wind cooling cold and hot water unit 2, water temperature in solar water container 6 is higher, when surpassing design temperature, water in the solar water container 6 can directly be transported in the operating water tank 7 by intake line 11, by operating water tank 7 to indoor fan coil system 4 or 5 heat supplies of indoor ground heating system, cold water in the operating water tank 7 is directly transported in the solar water container 6 by output pipe 12, reheats by solar thermal collector 1 then.Water in the solar water container 6 can provide heat by the water in 8 pairs of domestic water water tanks 9 of heat exchanger, moreover, wind cooling cold and hot water unit 2 also can be to the water heat supply in the domestic water water tank 9 by the heat exchanger 10 of self, domestic water water tank 9 can provide hot water output like this, domestic water water tank 9 also has the running water input port, for timely amount of makeup water in the domestic water water tank 9.
Be provided with the sensor that detects water temperature in solar water container 6, the operating water tank 7, guarantee at the weather of sun-drenched weather or sunlight deficiency or when overcast and rainy, this solar energy system all can stably freeze, heat, supply the domestic water of floor heating, supply heat, and make full use of solar energy, save non-renewable energy resources.
Specifically, at sun-drenched weather, if in summer, water temperature in the solar water container 6 surpasses 70 degree usually, the start-up temperature of setting lithium bromide cooling-water machine group 3 is 70 degree, then the water in the solar water container 6 provides enough heats to lithium bromide cooling-water machine group 3, water in 3 pairs of operating water tanks 7 of lithium bromide cooling-water machine group freezes, operating water tank 7 can provide cold air by indoor fan coil system 4 then, simultaneously, water in the solar water container 6 is by the water heat supply in 8 pairs of domestic water water tanks 9 of heat exchanger, and guaranteeing has hot water in the domestic water water tank 9; If in winter, when sunny, water temperature in the solar water container 6 is higher usually, (40 degree are design temperature when spending above 40, also can adopt other design temperature), water in the solar water container 6 can directly be transported in the operating water tank 7 by intake line 11, and to indoor fan coil system 4 or 5 heat supplies of indoor ground heating system, the water in the solar water container 6 also can be by the water heat supply in 8 pairs of domestic water water tanks 9 of heat exchanger by operating water tank 7.
In the weather of sunlight deficiency, if in summer, water temperature in the solar water container 6 can not reach 70 degree usually, if when having 60 to spend, then can't start lithium bromide cooling-water machine group refrigeration, need freeze this moment by the water in 2 pairs of operating water tanks 7 of wind cooling cold and hot water unit, thereby satisfy the refrigeration demand in room, water temperature in the domestic water water tank 9 is general to require to be higher than 40 degree, so the water in the solar water container 6 can be by the water heat supply in 8 pairs of domestic water water tanks 9 of heat exchanger; If in winter, when sunlight is not enough, when if the water temperature in the solar water container 6 can also be spent above design temperature 40, can be by being directly inputted in the operating water tank 7, satisfy heat demand,, start wind cooling cold and hot water unit 2 this moment if the water temperature in the solar water container 6 is lower than design temperature 40 when spending, water in the operating water tank 7 is heated, also need this moment wind cooling cold and hot water unit 2 by the water heat supply in the 10 pairs of domestic water water tanks 9 of heat exchanger of self.
In rainy weather, if in summer, water temperature in the solar water container 6 may be lower than the water temperature requirement in the domestic water water tank 9, for example 40 spend, then need to freeze by the water in 2 pairs of operating water tanks 7 of wind cooling cold and hot water unit, thereby satisfy the refrigeration demand in room, also need wind cooling cold and hot water unit 2 by the water heat supply in the 10 pairs of domestic water water tanks 9 of heat exchanger of self; If in winter, then to start wind cooling cold and hot water unit 2, the water in the operating water tank 7 is heated, satisfy the demand that heats, also need this moment wind cooling cold and hot water unit 2 by the water heat supply in the 10 pairs of domestic water water tanks 9 of heat exchanger of self.
In spring or autumn, may need to freeze or heat, sunny or sunlight is not enough or different weather situation such as overcast and rainy under, need be according to water temperature situation concrete in the solar water container 6, solar energy is passed through in selection, perhaps select by wind cooling cold and hot water unit 2, satisfy heating or freeze or supply floor heating or the hot domestic water demand of supply, how to select situation with top described summer or winter.
To sum up; this solar energy system; use solar thermal collector, wind cooling cold and hot water unit, lithium bromide cooling-water machine group etc.; under various weather or weather; all satisfy the refrigeration of indoor fan coil pipe or heat demand, and the function of finishing the domestic water of floor heating in the supply room, supply heat, this system makes full use of solar energy; to save electric energy, the protection environment.
