Heat supply technology review and engineering measurement analysis of medium and deep buried pipes

Presents the principles and characteristics of the medium and deep buried pipe heating system, and analyses the research progress of the technology. Taking a medium and deep buried pipe heating project in Xi’an as an example, carries out the continuous test and monitoring in operation conditions, and analyses the key indexes such as heat extraction at the heat source side, the heat supply at the user side, heat pump unit efficiency and system efficiency, to provide reference for the application of medium and deep buried pipe heating technology.
