[摘要]本文將復疊式制冷系統(tǒng)中制冷劑R22換成環(huán)保工質R410a,并且應用Ansys仿真模擬自動復疊制冷系統(tǒng)的蒸發(fā)溫度為-110℃時非共沸混合工質R410a/R23/R14的換熱情況,篩選出最大分離率對應的工質對及其配比,驗證R410a代替R22的可行性。

Abstract:In this paper,the cascade refrigeration system,refrigerant R22 will be replaceed with environmental working medium R410a.The heat transfer of the R410a/R23/R14 in the evaporation temperature of -110 ℃ is simulated by Ansys simulation,the working pairs according to the maximum separation rate are selected.Finnally calculate the feasibility of using simulation R410a instead of R22.
