Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The sensor for measuring the temperature of the phase change material can be selected from a thermocouple or a thermal resistance thermometer. In this embodiment, a platinum thermal resistance (Pt100) precision thermal resistance is used as the temperature sensor, and the signal conditioner 2 is an analog signal conditioning module; The two ends of the resistor PTD are introduced into ports 3, 4, and 5 of the analog signal conditioning module, and ports 1 and 2 of the conditioning module are connected to the adjustment resistor RG of the module's amplification range. Ports 7 and 8 of the conditioning module are analog power input, and ports 9 and 10 of the conditioning module are +5V power input and power common. The temperature change of the phase change material causes the change of the resistance value of the platinum thermal resistance, which...

Description

technical field [0001] The invention relates to the technical field of material testing, in particular to a testing and analysis system for phase-change energy storage materials. Background technique [0002] Using the phase change latent heat of phase change materials to realize energy storage and utilization is a very active research direction in the fields of energy science and material science in recent years. During the phase change process, the phase change energy storage material exchanges energy with the environment to achieve the effect of controlling the temperature of the environment. Compared with sensible heat energy storage, phase change energy storage has the advantages of high energy storage density (small size), constant temperature control, remarkable energy saving effect, wide selection range of phase change temperature (-20 ~ 1000 ℃) and easy operation. It has broad application prospects in many fields such as space power system energy storage, solar ene...
