Abstract

The invention discloses a system and a method for measuring thermophysical properties of a phase change material. The system comprises a phase-change material container filled with the phase-change material to be measured, a water circulation system, a heating control system and a data acquisition control device, wherein the heating control system is used for heating or cooling the phase-change material container through using the water circulation system so as to change the state of the phase-change material, and the data acquisition control device is used for calculating the thermophysical properties of the phase-change material. The system and the method solve the problems that a system or a method capable of completely measuring the thermophysical properties does not exist in the priorart, accurate data cannot be provided for engineering application since the measurement result error is large due to the fact that phase-change materials are mixed unevenly and the measurement cost is high.

Description

technical field [0001] The invention relates to the technical field of phase change materials, in particular to a system and method for measuring thermal physical properties of phase change materials. Background technique [0002] The determination of heat of fusion and heat of solidification of phase change materials in the market generally takes a small number of samples for measurement, and a small number of samples cannot fully represent the thermal properties of the prepared phase change materials. In the sample preparation process, the preparation of a small amount of samples is prone to problems such as uneven mixing and large measurement errors, so higher requirements are put forward for the measurement accuracy. Some instruments can be specially used to measure the heat of fusion of phase change materials, but for crystalline hydrated salts, the heat of solidification of phase change materials cannot be measured, for example, the heat of fusion and solidification of...
