Abstract: The work principle, primary units, installation requirement, technical advantage and application scope of the air source heating pump units system are presented. According to the geographical environment and climate characteristics of Jiangsu Oilfield, the advantages of air source heating pump technology in the field of energy-conserving in production are analyzed such as plenty of water, wide application scope, stable heating all day, security and environment protection, complete separation of water and electricity, intelligentized frost function, long life performance, and low maintenance cost. The feasibility of popularization and application of the technology that is used to alter the heating system in the Jiangsu Oilfield is demonstrated. Combined with the application of the air source heating pump technology, the problems existed are analyzed and the corresponding solutions are presented.
