沉浸竖板式浴室热泵换热器的研究

Study on the Immersed Vertical Plate Type Heat Exchanger for Bathroom Heat Pump

针对普通的浴室热泵换热器存在易堵塞、维护复杂等问题,开发了一种沉浸竖板式换热器,介绍了其结构、工作原理和特性参数方程,并针对关键要素对传热量和压降的影响规律进行计算分析,对换热器的传热系数、换热器操作参数和热泵性能指标的变化规律进行了试验研究,理论分析和试验结果对该浴室热泵换热器的设计和调控均具有较好的参考价值。

The immersed vertical plate type heat exchanger was developed based on the common bathroom heat pump heat exchanger which was easily- blocked and difficult to be regenerated. Structure, operating principle and characteristic parameter equations of the immersed vertical plate type heat exchanger were also introduced. The key factors influeneed on the heating load and the pressure drop were calculated and analyzed. The experiment research of the heat transfer coefficient, the operating parameters and the heat pump coefficient of performance were also conducted. The theoretical analysis and the experiment result had a good reference value in designing and controlling of the heat exchanger.
