• 中文摘要： 多種工作流體分別在四種冷凍系統之典型操作條件下的熱物性能已評估而得。在冷凍循環模擬過程中所需之冷媒熱力性質由 Iwai-Margerum-Lu狀態方程式預測。本研究所探討之流體中,我們發現HFC-1243(三氟丙烯)及HFC-143a(1 ,1,1-三氟乙烷)的熱物性能可媲美於目前廣為使用但已遭管制之氟氯碳化物冷媒。然而,這些流體在實際應用前,尚需斟酌其燃燒性與不良之油溶性及潤滑性。
• 英文摘要： The thermophysical performances were evaluated for a diversity of working fluids operated at the typical conditions of four different types of refrigeration systems. The Iwai-Margerum-Lu equation of state was used to estimate the thermodynamic properties of the refrigerants in the refrigeration cycle simulations. Among the fluids studied in this work, we found that HFC-1243 (trifluoropropene) and HFC-143a (1,1,1-trifluoroethane) have comparable thermophysical capabilities to the currently used CFC-refrigerants. However, the flammability and the poor oil-solubility and lubricity for such fluids should be taken into consideration for further applications.
