Problems solved by technology

However, the existing testing equipment for testing the performance of enclosure materials only focuses on the influence of temperature changes on the performance of enclosure materials (that is, the detection of heat transfer coefficient), but does not pay attention to the comprehensive effects of temperature, humidity, and rain
The detection of heat transfer coefficient has a single performance index, which cannot truly show the energy-saving performance under complex environmental changes
Especially in the detection of the performance of the enclosure material in this field, the humidity conduction measurement has never been considered, and the performance of the enclosure material is affected by the change of the comprehensive conditions in the actual use process, so it is necessary to develop a device that can accurately test the durability of the enclosure material.

Abstract

The present invention provides envelope material durability testing equipment and a method. The equipment comprises an outdoor environmental box simulation system, an indoor environmental box simulation system, a test piece frame system, a moisture transfer weight acquisition system and an automatic control and data acquisition system. The outdoor environmental box simulation system is connected with one side of the test piece frame system, the other side of the test piece frame system is connected with the indoor environmental box simulation system, and the moisture transfer weight acquisition system is placed at the middle part of the outdoor environmental box simulation system. The test piece frame system comprises a mobile test piece vehicle. The moisture transfer weight acquisition system comprises a moisture content collecting box, a high precision electronic scale, a circulating fan and a temperature and humidity sensor, a moisture content absorption material and a data acquisition and recording system. The equipment can simulate the natural environment factually and perform the repeated aging test and the test piece moisture content variation measurement on the systems of the exterior surfaces of all buildings. The equipment has the advantages of wide application range, simple operation, stable performance and high utilization rate.

Description

technical field [0001] The invention relates to a comprehensive performance testing device for building enclosure materials and a method for detecting the moisture transfer capacity (or moisture transfer coefficient) of the enclosure materials, in particular to an equipment and method suitable for accurately detecting the durability of the enclosure materials. Background technique [0002] With the construction demand of new-type urbanization in our country, the requirements for land saving, energy saving, water saving, material saving and environmental protection in the construction field are constantly increasing, and the design standards for building energy saving are constantly improving. Affect the energy saving effect of the whole building. However, the existing detection equipment for testing the performance of enclosure materials only focuses on the influence of temperature changes on the performance of enclosure materials (that is, the detection of heat transfer coe...
