Taurus Building Materials Heat Transfer Testing System (Heat Flow Meter Method)

HotBox testing room with heat flux meter, used to measure the static heat transfer characteristics of brick masonry.

The testing room consists of two parts, cold and hot, as well as a testing framework located between the two parts. Both parts include heat exchangers for temperature control and baffles with radial fans to generate necessary convection.

The environmental conditions outside the building were simulated in a cold area (on the left side of the image). The conditions inside the building were simulated in a warm area (on the right side of the above picture). The temperature range and convection meet the standard requirements, but can be adjusted as needed for specific applications. The heat flow meter with a protected area is installed in a warm area on the surface of the brick test specimen to be tested, and completely covers the component to be tested. A large number of sensors on the guide plate, inside the cross-section, and on the brick samples are used to capture temperature, convection, and humidity data.

The test frame placed between the cold and hot zones can accommodate brick masonry samples and minimize lateral thermal effects as much as possible. During the testing period, both parts of the testing framework and the chamber were kept airtight locked.

According to DIN EN 1934, determine steady-state heat transfer performance using a heat flow test chamber

The compact testing room TDW 4040 is designed specifically for testing brick masonry (such as bricks, lime sand bricks, concrete, aerated concrete) and essentially simulates the temperature and natural convection inside and outside buildings. As an option, the humidity levels of the two parts of the chamber can be set as needed. The setting of all parameters, complete data recording, detailed analysis, and printing of test reports are performed through the HotBox 2016 software on the measurement and control unit. Provide other optional equipment, accessories, and materials to assist in sample preparation and pre-processing to optimize the testing process.
