JW Building wall insulation performance testing equipment

The thermal insulation testing device for building walls is suitable for testing the thermal insulation properties of various materials such as walls, insulating glass and laminated glass. The equipment can realize the method of protective heat box and calibration heat box through different configurations. Accordingly, can according to specific condition, adjust measures to local conditions ground is used, give full play to its advantage.The box body of the equipment is made of \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"wood frame sandwich filled with polyurethane foam". The box body has good insulation and sealing performance, which makes the temperature control and experimental repeatability more stable. It is the first one in China.

3、Temperature control system

Due to large scope of knowing the conditions in the chamber test system (- 10 ℃, 20 ℃), so in the production of refrigeration system can only in accordance with the lowest temperature test requirements, at the same time consider to determine the cooling efficiency, cooling speed and temperature control accuracy requirement is very high, if the constant heating power, it is difficult to guarantee the stability of temperature, our company adopts computer PID control method, the metering box, shielding box and the temperature control of cold box is quite stable.
