Before the speech:
Hangzhou big yuan artificial environment equipment co., LTD., research and development of a kind of can use solar energy and gas energy integration of heating hot water units, through exploration, research and development and perfect, in 2010 by the state intellectual property office granted the patent for utility model, the patent number for ZL201020255756.8.The patent technology, marked the artificial environment equipment co., LTD. Hangzhou big yuan in the field of energy conservation and emissions reduction leading hvac forefront once again.
Is:
Solar energy is along with the global energy crisis and environmental problems and energy more and more be taken seriously, clean environmental protection, the use of it.Has abundant solar energy resources in China, the annual average sunshine time of more than 2000 hours, this is the basis of the development and utilization of solar energy provides a good condition.Gas energy with the implementation of west-east gas and Marine development and is widely used all over the country.The energy use has been alone in their respective fields, but will be limited to the geographical conditions, climate conditions, difficult to maximum advantage of energy use.Can use solar energy and gas heating hot water units with energy, by setting the matching connection gas burner, solar heating device and other related parts, can be directly use solar energy for heating or hot water or gas use, energy saving, environmental protection, economic and convenient to use.
Can use solar energy and gas heating hot water units of energy includes solar heating device, temperature sensors, plate heat exchanger, radiator, combustion system and control system, structure diagram,
g device;2 - temperature sensor;3 - pump 1;4 - a hot water device;5 - mix water valve;

16 of the combustion chamber is mainly composed of
1601 - ignition needle, insulating panel 1602 - burner, 1603 -, 1605 -, 1604 - combustion heat exchanger air pressure switch, 1606 - fan, etc
A, heating operation principle:
2 can sense the temperature sensor in the solar water temperature within the 1 t;
When t 60 ℃ or higher: 1 (3) start the pump, the water of the solar collector 1, according to G - J - I - E - F - G direction circulating;2 (11) starting pump, gas proportional valve closed, 13 of the water in the radiator 14 press R - S - K - L - M - N - O - P - U - V - R direction circulating;Two circulating water heat transfer in plate heat exchanger in 9, 14 gradually heats up the water in the radiator, heat within 14 to send to the room through the radiator, the purpose of heating.The solar heating effect into full play.
When t < 60 ℃ : 2 (11) starting pump, gas proportional valve open, ignition, ignition needle 1601 gas from gas interface 15 are lit, the flame heating through the combustion heat exchanger of the water in the 1604, the water of the cooling device 14, according to R - S - K - L - M - N - Q - V - t - R direction circulating;14 gradually heats up the water in the radiator, heat within 14 to send to the room through the radiator, purpose of heating.Play a role of heating gas energy at this time.
A, hot water works:
2 can sense the temperature sensor in the solar water temperature within the 1 t;
When t 50 ℃ or higher: 1 (3) start the water pump, solar collector in the storage of water flow in the direction shown by the F - G - H, 4 out of hot water is hot water device.The solar heating effect into full play.
When t < 2 (11) starting at 50 ℃, water pump, gas proportional valve open, ignition, ignition needle 1601 gas from gas interface 15 are lit, the flame heating through the combustion heat exchanger of the water in the 1604, the water of the combustion heat exchanger in 1604, according to K - L - M - N - O - K - P - U - W direction circulating;Water from the tap water interface 6 A - B - C - D - I - J - G - H direction, two way flow heat transfer in plate heat exchanger in 9, water is heated from tap water interface 6, 4 out of hot water is hot water device.Play a role of heating gas energy at this time.
During heating, because the solar energy is far less than the speed of gas heating hot water boiler heat absorption, so may appear in this the phenomenon of the utilization of solar energy in the system is too low, it can consider increasing the collector to solve.
