Embodiment Construction

[0012] The hot water recycling device of the present invention includes a solar water heater 1, an insulated water storage tank 2, an insulated tank 3, a thermoelectric power generation sheet 4, a voltage stabilizer 5, a storage battery 6, cooling fins 7 and 8, a micro water pump 9 and connecting water pipes. Such as figure 1 As shown, on the basis of the original solar pipeline, the route is modified, and the solar water heater, heat preservation water storage tank, heat preservation tank, radiator, and micro water pump are connected in sequence through the pipeline.

[0013] The entire hot water recycling device can be divided into three major functional modules - indoor heating, thermoelectric power generation, and small-space semiconductor refrigeration.

[0014] In the heating season, generally at night, the hot water in the solar energy is lowered into the heat preservation water storage tank 2 to keep warm, and the bathroom and the bedroom are heated at any time. When t...

Abstract

The invention relates to a solar energy water heater afterheat comprehensive using device which can maximize the using of the afterheat and realizes the indoor heating and temperature difference powergeneration function through a simple and direct circulating pipeline. In the heating season, the device firstly supplies heating to a bathroom and a bedroom; in other seasons, the afterheat is mainlyused for temperature difference power generation and hot water circulates and returns into the solar energy water heater to be heated again. The whole circulation system is controlled by an electronic self-control device and does not need to be operated manually. In addition, the system is simple and easy to be modified, has strong reliability, high energy utilization efficiency, lower cost and very strong practicability and excellent market development prospect.

Description

technical field [0001] The invention relates to heat and mass transfer, electronic self-control, and temperature difference power generation technology, and designs a set of solar water heater waste heat comprehensive utilization device to realize indoor heating, temperature difference power generation and small space cooling. Background technique [0002] In recent years, solar water heaters have developed rapidly. In 2007, the annual output of solar water heaters in my country has reached more than 20 million m 2 , Has become the world's largest producer and consumer market for solar water heaters. [0003] Solar water heaters can absorb a lot of energy every day, but their heat utilization rate is low at present. The large amount of hot water obtained by domestic solar water heaters is used for various needs of life, and there is still a large amount of surplus. Most of the energy is lost overnight, and the heat is not fully utilized. Due to the small heat capacity of s...
