Although the heat losses of the outdoor piping are minimised by thermal insulation, the distribution of heat from the heating plant to individual consumers of the technological heating media is always accompanied by losses. In the case of large transported volumes of the flowing media, the loss values are negligible. The mathematical and physical analysis of the heat loss of the outdoor heat distribution systems, insulated and non-insulated, has been carried out while using the parameters measured on the real piping system.

Heat Transmission

Considering that food always be spoiled in an oven, an analysis of the heat distribution of an object (pan) in a thermal insulation space has been done. The analysis based on the characteristics of heat transmission in an oven. A mathematical model is designed to illustrate the heating process. Specifically, in order to monitor the temperature of the object, pdetool in MATLAB is used to solve the heat transfer equation. Then to evaluate how an object performs in the oven, a method of standard deviation has been introduced. For the efficiency, valid heating area should also be considered. Thus an evaluation is made to choose a most preferring pan, which is balanced between heat distribution and valid heating area (number of pans). The experiment shows that shapes would devote much in performance. It is also demonstrated that there is a certain shape that can be most suitable to be a pan.
