The cycle test device comprises a control device, a cold water electric two-way valve, a cold waterreservoir, a cold water generator, a cold water pump, a hot water electric two-way valve, a hot water reservoir, a hot water generator, a hot water pump, a sample test box, a sample storage box and atemperature controller probe, wherein the hot water generator is connected with the hot water pump through a pipeline, the hot water pump is connected with the hot water reservoir through a pipeline,one side of the hot water reservoir is connected with the hot water electric two-way valve through a pipeline, the hot water electric two-way valve is connected with the sample test box through a pipeline; the other side of the hot water reservoir is connected with the sample test box through the hot water electric two-way valve; and the cold water generator is connected with the cold water pump through a pipeline.

Description

technical field [0001] The invention belongs to the technical field of durability cycle testing of phase change materials, and in particular relates to a durability cycle testing device and a testing method of phase change materials. Background technique [0002] With the increasingly prominent energy and environmental problems, phase change energy storage technology, which can solve the contradiction between energy mismatch in time and space, has attracted wide attention from various industries. As an energy carrier, phase change materials have high heat storage density, heat storage The heat release is approximately constant temperature, and the process is simple and easy to control. There are four main methods for the application of phase change materials in construction: direct addition method, infiltration method, microencapsulation method and stereotyped phase change materials. The direct addition method refers to the direct mixing of phase change materials with tradi...
