For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of solar energy-gas hot-water heating system; Comprise apparatus for heating water by solar energy; Wherein: this hot-water heating system also comprises gas-fired water heater, selector valve and attemperating unit, and first, second, third valve port of this selector valve is connected with the outlet pipe of cold water pipe, hot-water line and the said apparatus for heating water by solar energy of this gas-fired water heater respectively; This attemperating unit is used for controlling according to the hot water temperature of the outlet pipe of said apparatus for heating water by solar energy the connection direction of this selector valve.This selector valve has only 3 to connect direction; And the connection direction in the utility model obviously is meant outlet pipe and the cold water pipe of gas heater or the connection of hot-water line of apparatus for heating water by solar energy; Promptly can only be that the 3rd and first valve port is connected, or the 3rd and second valve port be connected.
One of improve: said attemperating unit comprises temperature-detecting device and control device; This control device is connected with said selector valve; This temperature-detecting device is used for directly or indirectly detecting the fluid temperature of the outlet pipe of said apparatus for heating water by solar energy, is preset with first temperature and second temperature in this control device, and this first temperature is more than or equal to this second temperature; When this fluid temperature during greater than this first temperature, this control device will be controlled this selector valve and connect its second and the 3rd valve port; When this fluid temperature during greater than this first temperature and less than this second temperature, this control device is kept original valve port, and to connect direction constant; When this fluid temperature during less than this second temperature, this control device will be controlled this selector valve and connect its first and the 3rd valve port.
Two of improvement: said attemperating unit comprises temperature-detecting device and control device; This control device is connected with said selector valve; This temperature-detecting device is used for directly or indirectly detecting the fluid temperature of the outlet pipe of said apparatus for heating water by solar energy; Be preset with the control temperature in this control device; When this fluid temperature is controlled temperature greater than this, this control device will be controlled this selector valve and connect its second and the 3rd valve port; When this fluid temperature is controlled temperature less than this, this control device will be controlled this selector valve and connect its first and the 3rd valve port.
Compared with prior art; Beneficial effect is: the utility model is provided with a selector valve between the cold water pipe of the outlet pipe of apparatus for heating water by solar energy and gas-fired water heater, hot-water line, and selects directly hot water (the 3rd and second valve port of selector valve is connected) to be provided or further to the user hot water (the 3rd and first valve port connection of selector valve) to be provided again after the heating through the gas heater heating earlier to the user through attemperating unit.If the leaving water temperature of solar water heater is higher, then select first kind of mode directly to supply water to the user; If the leaving water temperature of solar water heater is lower, then select the second way to supply water to the user indirectly accordingly.Therefore the utility model makes the user can make full use of original user gas heater equipment, selects not have the solar water heater of additional or reserve heater, reaches the optimum balance of economic benefit and energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the principle schematic of embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the solar energy-gas hot-water heating system of present embodiment comprises apparatus for heating water by solar energy 10 gas-fired water heaters 20, selector valve and attemperating unit 40.First valve port 31, second valve port 32 and the 3rd valve port 33 of this selector valve is connected with the outlet pipe 11 of cold water pipe 21, hot-water line 22 and the apparatus for heating water by solar energy 10 of this gas-fired water heater 20 respectively.This outlet pipe 11 also is connected with the main body of apparatus for heating water by solar energy through return pipe 12.
This selector valve has only 3 to connect direction; And the connection direction in the utility model obviously is meant the outlet pipe 11 and the cold water pipe 21 of gas heater or the connection of hot-water line 22 of apparatus for heating water by solar energy 10; Promptly can only be that the 3rd and first valve port 31 is connected, or the 3rd and second valve port 32 be connected.
This attemperating unit 40 is used for controlling according to the hot water temperature of the outlet pipe 11 of apparatus for heating water by solar energy 10 the connection direction of this selector valve.In the present embodiment, this attemperating unit 40 comprises temperature-detecting device 41 and control device 42.This temperature-detecting device 41 is used for directly or indirectly detecting the fluid temperature of the outlet pipe 11 of apparatus for heating water by solar energy 10.This control device 42 is connected with selector valve, and it both can preset one high and one low two temperature values, also can only preset temperature value.These temperature values can be to calculate automatically through factors such as weather, environment temperatures, also can be that the user's own input obtains.
With preset two temperature values is example, and first temperature is a high value, and second temperature value is than low value.This control device 42 decides the connection direction of selector valve according to the fluid temperature of the outlet pipe 11 of these temperature-detecting device 41 detected apparatus for heating water by solar energy 10.(1) when fluid temperature during greater than first temperature; This control device 42 will be controlled selector valve and connect its second valve port 32 and the 3rd valve port 33 (being that solar water heater directly provides hot water to subscriber equipment 50), and block between first valve port 31 and the 3rd valve port 33 this moment; (2) when this fluid temperature during greater than this first temperature and less than this second temperature, control device 42 both can have been kept original valve port, and to connect direction constant, also can select or the connection direction of default setting control selector valve according to the user; (3) when this fluid temperature during less than this second temperature, control device 42 will be controlled selector valve and connect its first valve port 31 and the 3rd valve port 33 (being offer subscriber equipment 50 again after water in the outlet pipe 11 of solar water heater need further heat through gas heater).
A control temperature also can only be set in the control device 42, and when this fluid temperature is controlled temperature greater than this, control device 42 will be controlled selector valve and connect its second valve port 32 and the 3rd valve port 33; When this fluid temperature is controlled temperature less than this, control device 42 will be controlled selector valve and connect its first valve port 31 and the 3rd valve port 33.
Therefore the hot-water heating system of present embodiment can automatically switch between apparatus for heating water by solar energy and gas-fired water heater, and whole process is all controlled the opening and closing of selector valve automatically by attemperating unit, need not user's manual operation, and is easy to use.
