Analysis and application of siphon negative pressure water intake in sewage-source heat pump system

Presents the siphon negative pressure water intake technology for a sewage-source heat pump system, analyses the principle of siphon pot water intake, and provides the calculation methods of siphon pot volume and expansion ratio. Based on engineering practices, presents the design parameters of siphon negative pressure water intake emphatically. The study result shows that the volume of siphon pot can be determined by the volume of the empty tube and the expansion ratio, the expansion ratio is between 1.3 and 3.3, and siphon negative pressure water intake can be used as an effective way for sewage-source heat pump system.
