【摘要】：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52.33k W,制冷性能系数为2.47,制热量为63.32 k W,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%。
[Abstract]:In order to solve the problems of poor heat transfer performance and large resistance in the traditional baffle tube shell dry evaporator, a new type of turbulent self supporting dry evaporator is proposed based on the idea of asymmetric space heat transfer. And it was assembled on the air-cooled heat pump for experimental test. The results show that the cooling capacity of air-cooled heat pump is 52.33 kW, the refrigeration performance coefficient is 2.47, the heating capacity is 63.32 kW, and the heating performance coefficient is 3.0. Compared with the same type of air-cooled heat pump with the traditional baffle tube shell dry evaporator, the heat transfer area of the dry evaporator is reduced by 33.3, the refrigeration performance coefficient is increased by 6.0 and the heating performance coefficient is increased by 15.8. the refrigerant charge is reduced by 7.1 percent.
