Model of heat losses from underground heat distribution system

Abstract

The effect of saturated steam vapor temperature on heat consumption in the process of color modification of acacia wood AIP Conference Proceedings 1889, 020006 (2017) Abstract. The paper describes the linear density of the heat flow using dimensional analysis in the case of underground, pre-insulated piping. The methodology makes it possible to determine the heat loss based on a simple criterial relationship. Heat losses in the piping system were also calculated using numerical simulation. The difference between the experimentally detected losses and the values obtained from the model is -3.6% to 6.4%. The results of the numerical simulation at an ambient temperature of 25°C differ from the experiment by -1.7%. At an ambient temperature of -10°C the difference is -4.0%.
