The temperature inside a refrigerator is t2°C and the room temperature is t1°C. The amount of heat delivered to the room for each joule of electrical energy consumed ideally will be : |
\(\frac{t_1}{t_1 + t_2}\) \(\frac{t_1 + 273}{t_1 - t_2}\) \(\frac{t_2 + 273}{t_1 - t_2}\) \(\frac{t_1 + t_2}{t_1 + 273}\) |
\(\frac{t_1 + 273}{t_1 - t_2}\) |
K = \(\frac{Q_2}{W}\) = \(\frac{1}{\frac{t_1}{t_2}-1}\) Q2 = \(\frac{t_2 W}{t_1 - t_2}\) Q1 = W + Q2 = \(\frac{t_1 + 273}{t_1 - t_2}\) |
