Building wall phase-change heat insulation effect testing system and using method thereof

Abstract

A building wall phase-change heat insulation effect testing system is characterized by comprising a water chiller unit (1), a computer desk (2), a control cabinet (3), a fan coiler (4), an electric heater (5), a test box (6), a protection box (7) and a test wall (8). The building wall phase-change heat insulation effect testing system is used for testing heat insulation effect of the building wall phase-change heat insulation system relative to a conventional building wall heat insulation system and provides reliable data guarantee for phase change material selecting of construction engineering.

Description

technical field [0001] The invention belongs to the field of building science and technology, and specifically relates to a building wall phase change thermal insulation effect testing system and a method of use thereof, which are used to test the thermal insulation performance of the building wall phase change thermal insulation system compared with conventional building wall thermal insulation systems. Insulation effect. Background technique [0002] Before the implementation of building energy-saving standards, the design and construction of buildings did not pay attention to the thermal insulation of the outer envelope structure, resulting in poor indoor thermal environment. With the improvement of people's living standards, higher and higher requirements are put forward for the comfort of indoor thermal environment. With the popularization of air-conditioning, the indoor thermal environment has been improved, but at the same time it has brought about a sharp increase i...

Problems solved by technology

[0005] At present, in engineering applications, phase change materials have not been widely used in building exterior walls. The important reason is that the test method for the energy-saving effect of phase change walls fluctuates too much, and it is impossible to accurately test the thermal insulation effect of phase change thermal insulation systems for building walls. , because phase change materials cannot be put into use in construction projects according to actual needs. The purpose of the present invention is to address the technical defect of inaccurate test accuracy existing in the existing phase change building material testing technology, and to provide a building wall phase change thermal insulation The effect test method and its special test system are used to test the thermal insulation effect of the building wall phase change thermal insulation system compared with the conventional building wall thermal insulation system, and provide reliable data guarantee for the selection of phase change materials for construction projects
