【摘要】：本文以R410A家用分体式空调机为原型,以新型的双排分液冷凝器,构建分液冷凝空调系统,并研究其系统匹配及综合性能。采用理论优化管程布置的双排分液冷凝器,实验研究了在毛细管长度为300 mm~800 mm和制冷剂充注量为950 g~1350 g条件下,分液冷凝空调系统性能的变化规律,并与原型系统作对比。研究表明,在制冷名义工况下,较原型系统,最优分液冷凝系统的能效比(energy efficiency ratio,EER)和制冷量高5.1%和4.2%,所需的毛细管长度少16.7%,而制冷剂充注量高8.6%。
[Abstract]:In this paper, R410A domestic air conditioner is used as the prototype, a new type of double separate condenser is used to construct the separate liquid condensing air conditioning system, and its system matching and comprehensive performance are studied. Under the conditions of capillary length of 300 mm~800 mm and refrigerant charge of 950g / 1 350 g, the performance of liquid-separated condensing air conditioning system is studied and compared with that of the prototype system. The results show that the performance of the system is better than that of the prototype system under the nominal condition of refrigeration. The energy efficiency and refrigerating capacity of the optimal condensing system are 5.1% and 4.2, respectively. The length of capillary tube is 16.7 less, and the charge of refrigerant is 8.6%.
