Find the maximum possible coefficient of performance for a heat pump used to heat a house in a northerly climate in winter. The inside is kept at 20°C while the outside is -20°C.
A heat pump has a coefficient of performance 3.0. How much heat is exhausted to the hot reservoir when 300 kJ of heat are removed from the cold reservoir?
what is the maximum possible coefficient of performance of a heat pump that brings energy from outdoors at 3.00°C into a 22.0°C house? (Hint: The heatpump does work W, which is also available to warm upthe house.)
