Analysis Device For Thermal Conductivity Of Floor

In recent years, as a kind of new technology, floor heating is becoming more and more popular. It has many advantages such as being of good performance on heating radiant, with more uniform surface temperature, beautiful and generous. Beijing government has taken floor heating as one of measures to eliminate city's pollution, while states strongly advocated the use of floor heting.According to the characteristic of the heating floor, this thesis have designed and developed the analysis device for thermal conductivity of floor through imitating the environment of floor heating. Its main research contents includes1. Temperature control based on integral separating PID control.2. Development of monitoring system for analysis device. The monitoring system was composed of temperature control sub-system, real-time monitoring sub-system, database sub-system, time-sharing collection sub-system, data modeling sub-system, historical data analysis sub-system, which was real-time monitored and under control by computer.3. Setting up the mathematics model of thermal conductivity of floor. According to the testing data got from experiment, the mathematics model of thermal conductivity of floor was set up and reached ideal approaching precision using curve fitting and GRNN (generalized regression neural network).According to practice use, it is well established for its fast speed of response, higher precision, wide range, and powerful capability of real-time and flexible operations. Its CAD system has a fine man-machine interface. The system can completely and variously simulate the testing process according to the testing data.There is no report about the testing device and analysis method for thermal conductivity of floor mentioned in this thesis. The device will provide effective scientific basis and research method for the measuring standard of thermal conductivity of heating floor.
