    Abstract: 本研究利用R410A冷媒所對應的莫利爾曲線,求得壓縮機在不同工作參數下,所對應理論吸入、吐出之溫度與壓力,再由冷媒的熱力性質,求得腔室內每曲軸角度對應不同的體積下,造成腔室內的壓力變化。


    (Energy Efficiency Ratio)1.8%;本研究藉由模擬可合理的解釋實驗結果。
    ;Mollier chart of R410A refrigerant is used to obtain the corresponding theoretical suction temperatures, discharge temperatures, densities and pressures at different working
    conditions. Then the corresponding volumes and pressures at different crank angles are calculated based on its thermodynamic properties.

    ANSYS is used to simulate the valve displacement of the rotary compressor under different operation processes. Under the fix of valve material mechanical properties (density, Young′s modulus and Poisson′s ratio) and top flange parts, by changing the valve thickness only, the instantaneous valve displacement and the compressor performance caused by the difference between internal and external pressures of the compressor chamber.

    Simulation shows that the displacement of 0.305mm valve is lower by 4.1% compared with that of 0.25mm valve under the same pressure loading. The experimental test verifies that 0.305mm valve increases the energy efficiency ratio EER (Energy Efficiency Ratio) by 1.8%. The simulated and experimental results are consistent each other.
