Abstract

The invention provides an efficient solar energy radiation heating water tank with an electric auxiliary heating function. The efficient solar energy radiation heating water tank is applicable to a solar energy radiation heating system, and solves the problems that in an ordinary solar energy water tank, cold water and hot water are mixed, low heat storage and heat release efficiency is caused, the electric auxiliary heating time is too long, the energy consumption is high, and the like. The efficient solar energy radiation heating water tank at least comprises a heat storage pipeline, a heat release pipeline, auxiliary heating equipment, an automatic water supplementing device and a high-temperature water and low-temperature water mixing prevention device. The efficient solar energy radiation heating water tank is designed according to a water temperature layering theory and a thermodynamic entropy theory, and is characterized in that an outlet of a heat storage water return pipe is formed in the upper part of the water tank, the heat insulation treatment is carried out, and a heat storage water supply pipe is arranged at the bottom of the water tank; an inlet of a heat release water supply pipe is formed in the upper part of the water tank, the heat insulation treatment is carried out, and a heat release water return pipe is arranged at the bottom of the water tank, and extends to the horizontal direction to realize the water return; an electric auxiliary heating device is put on the upper part of the water tank, and is near the position of a heat release water supply pipe opening; a baffle plate is arranged above the heat release water return pipe, and the cold and hot water mixing is effectively avoided. The efficient solar energy radiation heating water tank has the advantages that the heat storage efficiency and the heat supply efficiency are obviously improved, the auxiliary heating power is reduced, and the auxiliary heating time is reduced.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and is a device for improving the heat storage and heat release efficiency and the electric auxiliary heating efficiency of a solar heating system. Background technique [0002] Solar heating is an important part of the utilization of renewable energy. Solar energy has the characteristics of low density, low grade and difficult to collect, and the water tank is an important equipment for system storage and release of heat. Therefore, a reasonable design of solar heating water tank is the most efficient use of solar energy. One of the key links. [0003] At present, the water tanks used in solar heating systems on the market all have bottom-mounted water storage and discharge water pipe connections. In the heat storage cycle, the high temperature return water is directly mixed with the low temperature supply water; in the exothermic cycle, the high temperature supply water is directly mixed...

AI Technical Summary

Problems solved by technology

According to the thermodynamic entropy theory, when high temperature water is mixed with low temperature water, the total energy remains unchanged, but the energy quality decreases and energy consumption increases

At the same time, the traditional method is to place a high-power electric auxiliary heater directly at the bottom of the water tank to heat the water in the entire water tank, which takes a long time, low efficiency, and high energy consumption.
