Abstract

The invention relates to an energy storage and release test system and method for a non-ideal solid-liquid phase change material. The system includes: an energy storage device, a non-ideal solid-liquid phase change material, a fixed clamp, an inlet hose, an outlet hose, a first hose clamp, a second hose clamp, a third hose clamp, a fourth hose clamp, an inlet three-way ball valve and an outlet three-way ball valve. Through cooperative use of the rotatable fixed clamp, the inlet hose and the outlet hose, comparison test of the non-ideal solid-liquid phase change material's energy storage and release characteristics under vertical and horizontal conditions can be realized very conveniently. By arranging temperature thermocouples on a plane at a 1/2 height of an energy storage pipe and one radial section, the number of temperature thermocouples is greatly reduced under the circumstance of ensuring a reliable measurement result. Therefore, the invention provides a comprehensive energy storage and release test system and method for a non-ideal solid-liquid phase change materials.

Description

technical field [0001] The invention relates to a storage and discharge energy testing system and method of a non-ideal solid-liquid phase change material, belonging to the technical field of phase change thermal performance testing. Background technique [0002] Phase change energy storage technology is an important means to solve the uneven distribution of energy in time and space and the mismatch between supply and demand. It is widely used in the fields of solar energy utilization, wind energy utilization, industrial waste heat recovery, and power peak regulation. It is currently a hot topic in the field of energy storage technology. research direction. [0003] Phase change materials are the core part of phase change energy storage. According to the form of phase change, they can be divided into four forms: solid-gas, liquid-gas, solid-solid and solid-liquid. Among them, solid-liquid phase change materials are currently the most widely used of a class. Phase change ma...
