In a remote place, the heat energy is supplied to an absorption refrigeration system from a solar pond at \(125^{\circ} \mathrm{C}\) at the rate of \(4.5 \times 10^{5} \mathrm{~kJ} / \mathrm{h}\). The environment is at \(28^{\circ} \mathrm{C}\) and the cold space is maintained at \(-5^{\circ} \mathrm{C}\). Determine the rate at which heat is rejected from the low-temperature space.
