Composite energy storage device and energy storage method thereof

Abstract

The invention discloses a composite energy storage device. The composite energy storage device comprises an energy storage water tank. The energy storage water tank is connected with a solar device, an air source heat pump and a terminal. The energy storage water tank is internally provided with a thermocouple which is connected with an electric heating controller. The invention further disclosesan energy storage method of the composite energy storage device. Three energy manners of the solar energy, the air energy and the thermocouple are used for heating an energy storage medium, the resources are integrated more scientifically and reasonably, and the using cost is greatly reduced. Moreover, the tree heating technologies and equipment are relatively mature, simple and reliable, technical integration is relatively easy, the cost is low, application and popularization are easy, and the energy saving effect is good. Water serves as the energy storage medium, water is attractive in quality and price, no pollution is caused in the energy storage and energy releasing process, and the process is relatively environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of energy conservation and environmental protection, in particular to an energy storage device and an energy storage method thereof. Background technique [0002] At present, there are some deficiencies in the use of existing energy storage technologies, which are mainly reflected in the following aspects: 1. Phase change materials are expensive, and there are not many types of phase change materials; High; 3. The technical difficulty of releasing energy to the terminal is difficult, difficult to control, and the required supporting equipment and facilities are complex and costly. Therefore, designing an energy-saving and environment-friendly energy storage device with simple energy storage structure, low manufacturing cost, high energy storage efficiency and obvious energy-saving effect has become an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to...
