Provided is a high-temperature phase-change energy storage device used for a greenhouse. The device comprises an internal circulating heat exchanger providing heat supply for a greenhouse, a regulating system, and a non-pressure integrated structure device used for energy storage. The internal circulating heat exchanger is provided with a water inlet and a water outlet of load circulating water. The housing of the non-pressure integrated structure device is provided with a thermal insulation layer. A plurality of groups of energy storage units are arranged in the non-pressure integrated structure device used for energy storage, and ventilating ducts are reserved. A phase-change material is packaged in the energy storage unit, and electrical heating components are arranged in the energy storage unit. The electrical heating components are resistance bars or resistance wires. The internal circulating heat exchanger is communicated with the ventilating ducts in the non-pressure integratedstructure device used for energy storage by an airflow pipe. The airflow pipe is internally provided with a group of circulating fans used to realize heat storage and release of the phase-change material in the energy storage unit device. The group of circulating fans at least include a fan arranged in front of an inlet of the non-pressure integrated structure device used for energy storage, and afan arranged on the rear of the non-pressure integrated structure device used for energy storage.
Description
technical field [0001] The invention relates to an energy-saving technology, in particular to a high-temperature phase-change energy storage device and a use method. Background technique [0002] Greenhouse is an indispensable facility in facility agricultural production, and its main purpose is to produce agricultural products in non-cultivation seasons. Since the lower temperature in winter will adversely affect the crops in the greenhouse, effective warming and heat preservation have become important technologies to ensure high-quality and efficient production in the greenhouse in winter. Phase change energy storage material is a new material developed in recent years, which uses certain substances to absorb or release energy through phase change at a specific temperature. According to the energy complementary recycling mechanism, the mixing ratio of the phase change heat storage material is reasonably proportioned, and the phase change material is heated by the electric...
