Solar heat cabinet

Abstract

The invention relates to a solar heat cabinet which is characterized in that an inner shell of a heat collection, heat exchange and heat storage device of the heat cabinet is located in the center of an outer shell, a medium-low temperature phase change heat storage material is filled between the outer shell and the inner shell, a coil heat exchanger is arranged in the medium-low temperature phase change heat storage material, and a high-temperature heat medium is filled in the inner shell. And the electric heater is arranged in the high-temperature heat medium. A pipeline of the coil heat exchanger is communicated with a pipeline of the heat dissipation circulating device, and the pipeline of the heat dissipation circulating device and a pipeline of the heating device achieve heat exchange in the plate heat exchanger. And the electric heater is electrically connected with the inverter at the electric energy output end of the photovoltaic module through the grid-connected controller, and is also electrically connected with a mains supply power grid. Electric energy of the photovoltaic module and heat energy of the solar heat collector are efficiently collected and stored together, the structure is compact, and the size is small. The double-temperature heat storage scheme gives full play to the advantage of large heat capacity of the high-temperature heat medium, and effectively solves the problem that the output heat energy of the solar heat collector is low in winter, night and cloudy days.

Description

technical field [0001] The invention relates to a heating device that effectively utilizes solar energy, in particular to a solar thermal cabinet that can collect, store and utilize the electrical energy of photovoltaic modules and the thermal energy of solar collectors together. Background technique [0002] Making full use of solar energy to solve winter heating and long-term hot water supply in northern my country is a topic that has been continuously explored for a long time. [0003] Photovoltaic modules can convert solar energy into electrical energy, but the electrical energy generated by photovoltaic modules alone is not enough to ensure indoor heating in low temperature seasons, and the temperature of hot water generated by solar collectors absorbing sunlight energy will fluctuate with sunshine conditions, and it cannot be used. Guaranteed indoor heating demand in low temperature seasons. If the photovoltaic module electrical energy and the solar collector thermal ...
