中文摘要 |
本文以量測冷媒側壓力、溫度及參考壓縮機規格性能表來內插計算冷媒質量流率,並透過呼叫NIST REFPROP函式庫來計算一對多空調室外機冷媒出口及入口側之冷媒焓值,藉此來計算多聯空調機冷氣能力。並且在標準認證實驗室以空氣焓差法來測試多聯空調機氣測冷氣能力並進行兩方法量測誤差分析比較。測試結果顯示以空氣焓差法量測之冷氣能力為12.61kW,COP2.77,以冷媒焓差法量測計算之冷氣能力為14.60kW,COP3.21,兩方法量測誤差為15.78%。參考測試結果,未來可採用冷媒質量計來量測冷媒質量流率,達成進一步降低系統量測誤差。 |
英文摘要 |
In this study, refrigerant side pressures, temperatures, mass flow rate that calculated by compressor datasheet for variable refrigerant flow (VRF) system performance testing was tested and calculated by refrigerant enthalpy test method. And VRF system air side performance was tested with TAF certified laboratory by air enthalpy test method. VRF system cooling capacity is 12.61kW, COP 2.77 testing by air enthalpy test method testing, and cooling capacity is 14.60, COP 3.21 testing by refrigerant enthalpy test method testing. Comparison of two method testing results, the error is 15.78%. Finally, using refrigerant mass flowmeter to measure refrigerant mass flow and reduce more measurement error was recommended. |
