Measurement analysis on operation effect and energy saving of adjustable water jet pumps for heating

The adjustable water jet pump for heating can effectively solve the problem of thermal imbalance of end users caused by hydraulic maladjustment of the centralized heating pipe network. In this paper, the basic structure and operation principle of the water jet pump are presented, and the operation effect and energy saving of three residential areas in Tongzhou District of Beijing are measured during the heating season of 2018. According to the measured results, the application of the adjustable water jet pump heating system shows the operation state of “large temperature difference and small flow”, which has a better energy saving effect.
