Embodiment 1

[0054] First add water in the inner heating barrel 3, when the water reaches the mark in the inner heating barrel, stop adding water; then cover the inner heating barrel cover 4, and then cover the outer heat preservation barrel cover 2. The water bath section is ready for controlled heating. Then turn on 13 computers, and supply power to the voltage stabilizer 9 and the data acquisition instrument 12 of the heating barrel 3, and complete the heating setting on the 13 computers simultaneously. This mainly includes setting the phase change temperature of the phase change material, setting the heating time of the heat leakage test and the heat capacity test, and setting the heat leakage power of the heat leakage test. After these three settings are completed, click the start button on the interface to start heating. The temperature detector 6 collects data every 5 seconds, and converts it into a temperature value, which is displayed on the interface of the computer 13, and simu...

Abstract

The present invention relates to a phase change thermal storage tester, and consists of a water bath, a voltage stabilizer, a solid state relay, a power converter, a temperature detector, a data acquisition instrument and a computer. The water bath consists of an internal heating barrel, an electric heating rod and an external insulating barrel. One end of the voltage stabilizer is connected with a power supply, and the other end is connected with the electric heating rod and used for providing electricity for the electric heating rod. The solid state relay, the data acquisition instrument and the computer together form the monitoring and controlling part of the whole testing process. The data collected by the data acquisition instrument is used for judging whether the heating needs stopping or starting. The computer transmits commands to connect or disconnect the solid state relay. Aiming at the defect in the existing experimental method of researching or testing phase change materials for construction, the device can heat the water bath with the phase change materials for construction, measure the temperature by the temperature sensor, map the real-time temperature curve, control the starting and stopping of the heating device, and calculate the stored heat of the phase change materials for construction according to the test data.

Description

(1) Technical field: [0001] The invention relates to a phase change heat storage tester, which relates to a heat storage performance test of a building phase change material, that is, testing the heat that the building phase change material can absorb during the phase change process, and belongs to a testing device. (2) Technical background: [0002] In recent years, with the rapid development of China's economy and the improvement of people's living standards, people's requirements for indoor environment comfort are getting higher and higher. Among the many factors that affect the comfort of the indoor environment, room temperature is a very critical factor, and maintaining the room temperature at 16.0°C to 28.0°C is the key to maintaining the comfort of the indoor environment. In order to meet this standard, people use air-conditioning and heating systems to adjust the temperature, but the corresponding problems will lead to a substantial increase in energy consumption, ex...
