Abstract

The invention belongs to the technical field of building energy storage and conservation, and particularly relates to a phase-change heat storage testing device which comprises a heat exchange aluminum pipe, heat exchange aluminum pieces, an iron heat storer, an organic glass plate, a polyphenyl plate heat insulating layer and a temperature measuring thermocouple. The heat exchange aluminum pieces are uniformly fixed around the periphery of the heat exchange aluminum pipe to form a whole and arranged in the iron heat storer, the temperature measuring thermocouple is arranged on the iron heat storer, the polyphenyl plate heat insulating layer is fixed outside the iron heat storer, and the temperature measuring thermocouple is connected with a temperature data logger and computer equipment and measures and records temperature change inside a phase-change heat storage material. Heat storage and heat release of the phase-change heat storage material and temperature change in the heat storer can be tested clearly, testing principle is clear, and testing result is visual and accurate; the problem that a shell of the iron heat storer and the temperature measuring thermocouple for testing cannot be used repeatedly is solved, and only low-cost components like the organic glass plate need to be replaced in testing engineering, so that testing cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of building energy storage and energy saving, and in particular relates to a phase change heat storage test device and a phase change heat storage test method. Background technique [0002] With the improvement of people's living standards and the acceleration of urbanization, building energy consumption has accounted for 27% of the total energy consumption of the whole society. According to the experience of developed countries, building energy consumption will reach more than 30% of the total energy consumption of the whole society. Such a large building energy consumption has undoubtedly caused a huge burden on the whole society, and it is urgent to adopt new technologies for building energy conservation. In buildings, energy demand and supply have a strong dependence on time. In order to solve the contradiction between energy demand and supply imbalance in buildings, improve energy utilization efficiency...
