Resultate zu Leistungsziffer einer Wärmepumpe

1. 1. 2.67 kW
   2. 34.2 W/K, 39 W/K, 4.8 W/K
   3. 1.36 kW
2. 1. [math]\epsilon_C = \frac {I_{W2} } {P_{rev}} = \frac {T_2 I_{S2}}{\Delta T I_{S2}} = \frac {T_2}{\Delta T} = \frac {T_2}{T_2 - T_1}[/math]
   2. ca. 273 K (0°C)
   3. [math]\eta = \frac {\epsilon}{\epsilon_C} = \frac {\frac {I_{W2}} {P_{el}}} {\frac {I_{W2}} {P_{rev}}} = \frac {P_{rev}}{P_{el}} = \frac {\Delta T I_{S2}}{P_{el}}[/math] [math] = \frac {\Delta T I_{W2} / T_2}{P_{el}} \eta = \frac {\Delta T} {T_2} \cdot \frac {I_{W2}}{P_{el}}[/math]
   4. 66% bei 26°C, 52% bei 57°C
