Problems solved by technology
But in sunny summer and autumn seasons, the water in the water heater tank can reach a high temperature above 90°C in a short period of time, so that the heat-absorbing tube can no longer absorb and utilize solar energy.
Moreover, the temperature itself is high in summer and autumn, and people's utilization of hot water is not high. As a result, a large amount of hot water in the water heater is not used, and eventually it is lost to the environment, causing the collected heat to be wasted in vain.
Both of these aspects make the overall energy efficiency of solar water heaters not high

Embodiment Construction
[0025] The technical solutions of the present invention will be described in further detail below through specific implementation methods.
[0026] see figure 1 , The embodiment of the present invention provides a fully automatic solar water heater power generation device, which is mainly composed of a solar water heating system connected by pipes and valves, an organic Rankine cycle system and a cooling system.
[0027] The solar hot water system consists of a solar water heater 1, a high-level water tank 2, a dual-temperature dual-control thermostat 3, an evaporator 4, a heat source water pump 5, a heat source water pump temperature control valve 6, a water supply valve 7, a water supply pump 8 and a bathing valve 9 composition. Tap water flows into the high-level water tank 2 from the upper water pump 8 and the upper water valve 7, and flows out from the lower end of the high-level water tank 2 into the solar water heater 1 for heating to form hot water, which then passes ...

The invention provides a solar water heater power generation device, which includes a solar water heating system, an organic Rankine cycle system and a cooling system connected in sequence. The solar water heating system consists of a domestic hot water system and a power generation hot water system. It includes a dual-temperature dual-control thermostat installed in the water tank of the solar water heating system, and the dual-temperature dual-control thermostat controls the hot water system for power generation, the organic Rankine cycle system and the Switching on and off of the cooling system. The present invention also provides a method of using the above-mentioned device. The solar water heater can not only provide domestic hot water, but also provide hot water for power generation, thereby improving the utilization rate of the solar water heater, and avoiding the disadvantages of frequent start and stop of the system caused by single temperature control. The above-mentioned device adopts solar heating and power generation, can alleviate energy crisis and reduce environmental pollution, and has simple structure, safety and reliability, and is convenient to use, and is especially suitable for use in families and small units.
Description
technical field [0001] The invention relates to a device for comprehensive utilization of solar thermal energy and a method for using the same, in particular to a device for generating electricity for a solar water heater and a method for using the same. Background technique [0002] As we all know, solar energy is an inexhaustible clean energy. The use of solar energy can reduce the consumption of fossil fuels such as coal and oil, and is of great significance to reduce environmental pollution and ecological damage. Therefore, popularizing and promoting solar energy is one of the effective ways to save energy and protect the environment. [0003] Solar water heater is a kind of solar energy utilization. It can directly convert solar energy into water heat energy, which is convenient for people to wash and bathe, so it has been widely used. But in sunny summer and autumn, the water in the water heater tank can reach a high temperature of more than 90°C in a very short peri...
