Description

Water supply system for combined utilization of solar energy and fuel gas
Technical Field

At present, with the increasing shortage of earth resources and the high importance of the country on environmental protection and energy conservation, the green energy-saving technology is more and more widely applied to our lives. As is well known, solar energy is the cleanest, most readily available, high-efficiency, renewable, green energy source. With the continuous development of solar hot water technology, the solar hot water technology is more and more widely applied to the real life of people nowadays to provide hot water for the life of people. However, the amount of heat and temperature generated by the solar water heating system are controlled by the weather conditions, so that the solar water heating system cannot supply hot water at any time in all weather according to the requirements of people. However, the quality requirements of people for life are high, and in order to meet the requirement of people for supplying hot water all weather, a set of spare conventional heat source equipment is required to be additionally added as an auxiliary heat source to supply hot water according to the specification requirement. How to enable two sets of equipment to be smoothly and reasonably connected and matched for use and to make full use of solar energy to the maximum extent is worth carefully knocking.
The phenomenon that a residential building household solar water heating system and a household gas water heater coexist and share exists for many years, but how two systems are reasonably connected together does not have a good processing mode all the time.

The using process is unstable: when the hot water in the solar water tank is used up in the process of using the solar hot water (for example, in the process of showering), the control valve needs to be manually switched by using a kitchen, so that the original enjoyable bathing state is lost instantly. Energy waste: when the weather conditions are not good, the temperature of hot water in the solar water tank may not be very high, but when the temperature is certain, the temperature of the hot water is not enough when the solar water tank is used alone, but the hot water is completely abandoned, so that the waste is very high. Water waste: solar energy is normally installed outside a roof or a balcony, and a pipeline from a water outlet pipe of a solar water tank to the indoor is usually long and basically not circulated, so that water in the pipeline at the section is cold water in the initial use, cannot be used as hot water, and is wasted.
