Thermal transfer experimental analyzer for building components using the protective hot box method

DRX-I-BXThermal transfer experimental analyzer for building components using the protective hot box method

This device uses the hot box method to detect the heat transfer coefficient of building components. A hot box is used on the inside of the tested area to simulate the indoor conditions of the heating building and make the temperature inside the hot box consistent with the indoor air temperature, while the other side is the outdoor natural conditions. Maintain the temperature inside the hot box higher than the outdoor temperatureAbove 8K, the heat flow of the tested area always flows from indoors to outdoors. When the heat transfer reaches equilibrium, the heating amount of the hot box is the heat transfer amount of the measured part, which is recorded in real time，The calculation can obtain the heat transfer coefficient value of the tested component.comply with JGJT 357-2015 Technical specification for on-site detection of heat transfer coefficient of enclosure structure

The hot box material of this product is made of steel plate, which not only has a light overall structure, but also has good insulation effect. The bottom of the hot box adopts universal casters with brake mechanism, which is easy to move and has good self-locking performance. The two ends of the fixture are connected by universal joints, and the middle is equipped with a threaded locking mechanism, which is convenient, simple, reliable, and has good sealing performance for clamping. The system has a high degree of automation, good stability, and reliability. The entire process of the product is controlled automatically by a computer,PID adjustment, high accuracy, can directly perform data analysis and generate reports. Interface based connection, easy wiring, and intuitive display. The measurement and control system has high accuracy and is easy to maintain and use. All temperature measuring points are equipped with imported digital temperature sensors, which have high measurement accuracy, wide range, and stable performance.
