Abstract

The invention provides a solar phase change heat storage heating device and a heating method thereof. The heating device comprises a shell, wherein the interior of the shell is divided into an energy storage heat exchange area and a control area which are independent of each other through a partition plate, at least one phase change heat storage piece is arranged in the energy storage heat exchange area, and the shell where the energy storage heat exchange area is located is externally connected with a solar heat collector; an electric heater is arranged on the side, located in the energy storage heat exchange area, of the partition plate and comprises a box body filled with a heat exchange medium, and a heating assembly is arranged in the box body; and a control assembly and a cooler are arranged in the control area, the cooler is used for cooling the control assembly, and the control assembly is electrically connected with the electric heater. The electric heater is controlled through the control assembly, off-peak electricity and solar energy are fully utilized, heat is stored and utilized through the phase change heat storage pieces, and the energy storage device has the advantages of being compact and simple in structure, good in energy storage effect, convenient to operate, low in cost and the like.

Description

technical field [0001] The invention belongs to the technical field of heating, and in particular relates to a solar phase change heat storage heating device and a heating method thereof. Background technique [0002] Clean heating refers to a heating method that uses clean energy such as solar energy, industrial waste heat, and grid electricity to achieve low emissions and low energy consumption through efficient energy use. [0003] Among them, solar energy is the most common and the most common green renewable energy, which can be directly developed and utilized without mining and transportation. However, solar energy also has limitations. It is greatly affected by the weather, and it cannot be used in rainy weather or at night. Using solar energy combined with off-peak electricity for heating and reducing peak electricity demand can effectively relieve the pressure on the power grid. [0004] CN209084898U discloses a phase-change energy storage type solar fresh air hea...
