CO2跨临界循环中非绝热毛细管传热性能的试验研究
Experimental Study on Heat Transfer Performance of Non -adiabatic Capillary Tubes in CO2 Cross Critical Cycle
摘要
Abstract
In order to test under the same conditions,CO2 trans critical cycle non-adiabatic capillary tubes of various sections of the heat transfer ability.And test the capillary inlet pressure 10MPa,inlet temperature is 39℃,evaporation temperature of 7℃, 1kW refrigerating capacity,length of 5 kinds of inner diameter of capillary and capillary for calorimetric changes with the capillary diameter,set up a CO2 trans critical cycle experiment station,has been tested.The test results show that:non-adiabatic capillary tube in the supercritical region for heat capacity of the strongest,the subcritical two-phase region heat capacity of the weakest ex-change and heat transfer in capillary with the capillary diameter increase and increase.关键词
