|
摘要
为探讨新型碳氢制冷剂在食品制冷系统应用的可行性,基于R600a制冷系统,设计一套制冷系统测试装置,主要由制冷系统、温度监测系统和压力检测器等组成;用环境友好型碳氢制冷剂HCR22替代制冷剂R600a,以制冷系数和制冷量为指标,对比了2种制冷剂的制冷效果。结果表明:HCR22用于R600a系统,相比R600a,充注量减少13.33%,制冷系数提高10.53%,系统节能3.16%;系统运行12h,HCR22和R600a的制冷量分别为7 306.64,6 796.68kJ。该研究结果为新型制冷剂HCR22替代R600a提供了依据和支持。
In order to explore the feasibility of the application of new fluorine free refrigerant in the existing refrigeration system,a traditional one based on R600 arefrigeration,a testing equipment of new refrigeration system was designed.This new testing equipment was dominated by a cooling equipment,temperature tester and pressure detector.In this study,the refrigerant R600 areplaced by a new type of fluorine free refrigerant HCR22, and the coefficient of performance and cold storage capacity were taken as indexes,and conducted an experiment for 12 h,the refrigerating capacity of two refrigerants in different quantity of charging ratio was studied.The results indicated that compared to R600 a,the best filling ratio of HCR22 was less 13.33%,but the refrigeration coefficient was higher10.53%,and the system energy was less 3.16%.When the refrigeration system was run for 12 h,the refrigeration ability of HCR22 was found better,and the cooling ability of HCR22 and R600a were7 306.64 kJ and 6 796.68 kJ,respectively.This study provided evidences and technical support for the new type refrigerant HCR22 replacing the R600 arefrigerant.
