Solar water heater system with thermoelectric power generation function and water feed methods based on same

Abstract

The invention relates to a solar water heater system with a thermoelectric power generation function and water feed methods based on the same. The solar water heater system with the thermoelectric power generation function comprises a water storage tank; a hot water cavity, a partition cavity and a cold water cavity are arranged from top to bottom in the water storage tank; a plurality of electrically connected thermoelectric power generation modules are arranged in the partition cavity at intervals, and an electric lead electrically connected with the thermoelectric power generation modules is led out from the partition cavity; the cold water cavity is connected with a water feed tube which is connected with a tap water system; a main water outlet tube is connected to the hot water cavity; and an intermediate tube is connected between the cold water cavity and the hot water cavity. Based on the solar water heater system, the two water feed methods are provided for further improving the power generation effect of the system through intermittent water feeding on the premise that the normal use of a water heater is not affected. The solar water heater system substantially increases the energy utilization rate and reduces heat energy waste, and the whole system is simple in structure, convenient to achieve, and stable and reliable in operation. The water feed methods further guarantee the power generation effect and utilize the energy more efficiently.

Description

technical field [0001] The invention relates to the field of solar energy applications, in particular to a solar water heater system with thermoelectric power generation function and a water filling method based on the system. Background technique [0002] Solar water heaters are currently the most widely used solar products. Solar water heaters generally include water storage tanks, solar collectors, water inlet pipes and outlet pipes. The water inlet pipes are connected to the tap water system. When hot water is needed, the hot water is led out through the water outlet pipe to provide domestic hot water. Some water heaters share one pipeline for water inlet and outlet, and the water inlet and outlet cannot be carried out at the same time. Other principles are the same as those for water heaters with two pipelines. [0003] Although solar water heaters have made outstanding contributions in the field of clean energy utilization, there are still deficiencies in their speci...

Problems solved by technology

[0003] Although solar water heaters have made outstanding contributions in the field of clean energy utilization, there are still deficiencies in their specific use; the time people really use hot water is very little in a day, and for most of the rest of the time, although people do not Hot water is used, but the water heater is always working. When the water temperature reaches boiling (or very high temperature), the solar heat collected by the solar collector is wasted; Fill the water tank with water, and then use the solar collector to heat the whole tank of water. When it reaches a certain temperature, due to the high temperature of the water, it is easy to convert the water into water vapor and discharge it from the top exhaust port or overflow port, resulting in water loss. waste

For the waste of water, it will lead to a reduction in the amount of hot water or the need to re-open the water supply valve for refilling. There is currently no solution to the waste of heat.
