Product Introduction
Shanghai Jingge Instrument Equipment Co., Ltd. has developed a constant temperature method floor thermal conductivity analyzer based on the environment and conditions required to simulate the process of floor thermal conductivity. The system is divided into three parts: overall structure, electrical and control system. The overall structure is the main hardware equipment of the system, mainly composed of two compartments, and the space between the upper and lower compartments, as well as between the upper and lower compartments and the external environment, is sealed. The lower compartment has heating and cooling pipelines; The electrical part is the functional equipment of the system, including solid-state relays, compressors, and other electrical components; The control system includes LCD touch screen display, sensors, etc. It is the core of the floor thermal conductivity analyzer and also the part for collecting and storing experimental data.
Reference standards
LY/T 1700-2018 Wooden flooring for underfloor heating
GB/T 41547-2022 Wooden flooring for underfloor heating
Application area
The floor thermal conductivity analyzer is mainly used to measure the thermal conductivity of wooden flooring for underfloor heating, in order to investigate its thermal conductivity when applied to underfloor heating, and provide important quantitative references for measuring the quality and application of flooring.
Product Overview
The floor thermal conductivity analyzer is divided into two compartments, namely the upper compartment and the lower compartment. The heating and cooling are controlled by PID calculation to adjust the temperature change of the lower compartment and meet the experimental requirements.
By using a refrigeration compressor and heating device, heat is increased or decreased, and the temperature inside the cabin is adjusted through an evaporator to stabilize the temperature of the lower cabin of the working cabin at 70 ℃, with an accuracy controlled within ± 0.05 ℃.
In the upper cabin, according to standard requirements, two temperature sensors are placed on the test piece to measure changes in the surface temperature of the floor; After receiving the temperature response and meeting the requirements of the experimental temperature, the controller can calculate the rate of temperature change, which is the floor efficiency.
The ambient temperature requirement for use is less than 35 ℃ (customers can also specify a temperature such as 20 ℃ and maintain the equipment at that temperature for a long time). The results and conditions of the test may be affected by the ambient temperature.
