Embodiment 1

[0081] Weigh 100g of glycerin as the reference substance and 100g of barium hydroxide octahydrate, distribute them into two flasks;

[0082] Extend the two temperature measuring K-type thermocouples of the data acquisition system into the glycerin and barium hydroxide octahydrate to measure the internal temperature of the glycerin and barium hydroxide octahydrate, and fix the two thermocouples with a rubber stopper. The two flasks are sealed, and then the two flasks are placed in an oil bath filled with silicone oil, and the two flasks are heated through the oil bath, and heated to 100°C, at a constant temperature;

[0083] When the oil bath starts to heat up, the automatic temperature data acquisition system is started. The two temperature measuring thermocouples respectively test the real-time temperature of the glycerin and barium hydroxide octahydrate in the heating process, and transmit the measured data to the automatic temperature data acquisition system;

Abstract

The invention discloses a temperature testing device and a temperature testing method of a phase-change energy storage material. The temperature testing device comprises temperature control equipment(1), a temperature data acquisition system (2), a container I (3) used for containing a reference substance and a container II (4) used for containing a phase change energy storage material to be measured. In the invention, the reference substance and the to-be-measured phase change energy storage material are heated and cooled through the temperature control equipment; and the temperature data acquisition system is used for measuring and acquiring the temperature of the reference substance and the to-be-measured phase change energy storage material in real time so as to acquire heating and cooling curves so that the phase change temperature and a supercooling degree interval of the to-be-measured phase change energy storage material is obtained. The temperature testing device disclosed bythe invention is simple in structure, reasonable in design and low in cost, and the testing method is simple and convenient to operate, accurate in measurement, high in efficiency and suitable for popularization and implementation.

Description

Technical field [0001] The invention belongs to the technical field of phase change energy storage materials, and specifically relates to a temperature test device and a test method for phase change energy storage materials. Background technique [0002] In recent years, phase change energy storage technology has received more and more attention and development in the fields of renewable energy utilization, energy saving and consumption reduction, and its applications in HVAC systems have also increased. Develop phase-change energy storage materials used in the field of air-conditioning, which can convert cheap electric energy from low electricity consumption into heat energy and store it in the phase-change material. This part of the heat is released during the peak of electricity consumption, reducing the electricity consumption during the peak period. The role of peak clipping and valley filling. Among the currently known energy storage methods, the solid-liquid phase change ...
