Abstract The earth to fluid pipe (ETFP) system has been widely applied to various energy
engineering. The numerical model of the heat transfer process in the ETFP system with a
shallow-buried horizontal or a deep-buried vertical U-shape pipe adopted in practical
engineering was established and the model distinctions were pointed out. The comparison
of the thermal performance between the two types of ETFP system under various schemes
was conducted on the basis of numerical prediction. The results showed that the thermal
parameters of the ETFP system with a shallow-buried horizontal pipe were influenced
by the inlet velocity and ground temperature obviously.… More >
