Calculation of the Maximum Length of the Directly Buried Cooling Pipes Applied in the District Cooling System (DCS)

Abstract:

Formula of the maximum length of direct burial cooling pipes used in the district cooling system (DCS) was derived, by means of establishing the mathematical relationship between the maximum temperature rise of the pipe, under which the energy efficiency of the refrigeration unit would not decrease, and the thermal equilibrium of the pipe. And an engineering application with DCS in Zhuzhou was analyzed. The results showed that the insulation measures should be applied to the directly buried cooling pipes in engineering applications, appropriately with a thermal insulation layer of 0.04m.
