Method for testing heat storage performance of building material and tester

Abstract

The invention discloses a method for testing heat storage performance of a building material and a tester. The tester mainly comprises a heat insulation barrel, an environment chamber, a D / C converter, an A / D converter, temperature sensors, an electric quantity sensor and a computer. The temperature sensors are arranged in the heat insulation barrel and the environment chamber respectively for measuring the temperatures of the material, the environment chamber and the inner and outer walls of the heat insulation barrel; the computer controls the heating power of a heating rod through the electric quantity sensor and the D / C converter; and temperature signals are monitored and recorded by the computer through the temperature sensors and the A / D converter. A computer program can calculate the heat storage performance of the material through a temperature curve of heating and heat release processes. Aiming at the condition that the conventional method for testing the heat storage performance of the material in the search of the building material, particularly a building phase change material, is insufficient, the method of the invention simply and quickly tests the heat storage performance of the material during change at a certain temperature interval, has the characteristics of high detection precision, strong reliability, low cost and the like, and can realize automation of the test process at the same time.

Description

technical field [0001] The invention relates to a building material heat storage performance tester, which relates to a heat storage performance test of a building material, that is, measuring the heat absorbed / dissipated by a material during a temperature change, and belongs to a measuring device. Background technique [0002] The research on the heat storage performance of building materials has a positive effect on reducing building energy consumption and improving building comfort. Especially in areas with large temperature differences between day and night, the application of phase change materials with large heat storage can greatly reduce energy consumption while ensuring building comfort. Adding phase change materials with large heat storage capacity to ordinary building materials can increase the heat capacity of building maintenance structures and increase the thermal inertia of buildings. During the day when the temperature is high, the phase change material diss...

Problems solved by technology

However, there is a lack of means to test the heat storage performance of building materials, especially the phase change heat of building phase change materials, so that there is no unified standard and specification in the industry, which limits the development of the entire building phase change material industry.
