Abstract

An analysis of the known methodology for determining heat losses by the maximum linear density of a heat flux during movement of a high-temperature heat agent in a pipeline has been carried out. Based on heat transfer equations, the refinement dependence for calculating heat losses in a heat pipe has been obtained and the criterion whose value determines the degree of reliability of the method for calculating heat losses from the maximum linear heat flux density was introduced. The calculation of heat losses during hot water flow in an insulated and non-insulated pipeline of the heat supply system according to the dependences discussed above has been made, the results obtained have been analysed.
