中文摘要 | 依據照力學第二定律,可利用工作流體對之物流,在相對於操作溫度,壓力下之熱焓值、熵值,以及物流量所推演之方程式,計算出加熱用吸收熱泵之(COP)[8fa7]及其上限效率η□和下限效率η[8ecf]。其中熵值可以部分分子熵之方式算出。本文利用H₂O/LiBr及H₂O/H₂SO₄兩工作流體為例,計算在特定條件下之(COP)[8fa7]值,η□及η[8ecf]值。吸收熱泵以T-S圖形式繪出,可為詮釋吸收熱泵特性及物流流向之工具。 |
英文摘要 | Thermodynamic efficiencies of absorption heat pumps for heating, including upper limit η□ and lower limit η□ and (COP)[8fa7] values, were derived based on the second law analysis. The derived efficiencies were expressed as equations of enthalpy, entropy, temperature and flow rates which could reflect the operating conditions and thermodynamic properties for different working fluid-absorbent pairs. To calculate these values, the solution entropy and partial entropy of working fluid in the solution, using H₂O/H₂SO₄ and H₂O/LiBr as examples, were also estimated. The related Moiller T-S diagram of AHP cycle, using H₂O/H₂SO₄ as an example was constructed as a tool to interprete the system characteristics. |
