针对传统折流板管壳干式蒸发器存在换热性能不佳和阻力大的问题,基于非对称空间传热理念,提出一种新型顺紊流自支撑型干式蒸发器,并将其装配在风冷热泵上进行实验测试研究。测试结果表明:风冷热泵的制冷量为52.33 kW,制冷性能系数为2.47,制热量为63.32 kW,制热性能系数为3.0。实验对比配置传统折流板管壳干式蒸发器的同型号风冷热泵,其干式蒸发器的换热面积减少33.3%,制冷性能系数提高6.0%,制热性能系数提高15.8%,制冷剂充注量减少7.1%。 |

A novel turbulent flow self-supported dry-expansion evaporator based on unsymmetrical space heat transfer concept was presented in order to overcome poor heat transfer performance and high resistance problems of conventional baffle shell-and-tube dry-expansion evaporators. The new evaporator was installed and evaluated on an air-cooled heat pump. The results show that the cooling capacity of the air-cooled heat pump is 52.33 kW, and the cooling coefficient of performance (COP) is 2.47. Moreover, the heating capacity is 63.32 kW and heating COP is 3.0. Comparative experiments with the same type of air-cooled heat pump were tested using a conventional baffle shell-and-tube dry-expansion evaporator. The heat transfer area of the novel evaporator is reduced by 33.3%, and the cooling COP is increased by 6.0%. Moreover, the heating COP is increased by 15.8% and the amount of refrigerant charge is reduced by 7.1%. |
