摘要
为了提高空调性能,两器中胀管的选材大多为铜,随着空调器的快速发展和国际铜价的持续升高,制冷空调行业采用的换热器逐渐向着高能效、小体积、低成本的方向发展.使用更小管径的铜管或者直接减少铜管数量可以满足以上需求.以2 P天花机为研究对象,其蒸发器使用D5铜管,控制迎风换热面积、铜管数量不变,通过对蒸发器分流毛细管进行调整、以及调整分路两种方式,将各分路出口温度温差控制在3℃以内,调整前APF为3.37.通过两种方式调整后,APF分别为3.57、3.6,分别提升5.9％、6.8％,通过最终结果比较得出结论,流路均匀对空调系统整体性能及能效有很大的影响.
Abstract
In order to improve the performance of air conditioning,the material selection of the expansion tube in the two units is mostly copper,with the rapid development of air conditioners and the continuous rise of international copper prices,the heat exchangers used in the refrigeration and air conditioning industry are gradually developing in the direction of high energy efficiency,small volume and low cost.The use of smaller pipe diameter copper pipe or directly reduce the number of copper pipe can meet the above needs.Taking the 2 P ceiling machine as the research object,the evaporator uses D5 copper tube,and the upwind heat exchange area and the constant number of copper tubes are controlled to be unchanged.The temperature difference at the outlet of each branch is controlled within 3℃ by adjusting the evaporator shunt capillary tube and adjusting the shunt,and the APF before adjustment is 3.37.After adjustment by two ways,the APF is 3.57 and 3.6,respectively,with an increase of 5.9％and 6.8％,through the final result comparison,it can be concluded that the flow path uniformity has a great impact on the overall performance and energy efficiency of the ceiling machine.
