WebA Carnot engine has the maximum possible efficiency of converting heat into work between two reservoirs, but this does not necessarily mean it is 100% 100 % efficient. As the difference in temperatures of the hot and cold reservoir increases, the efficiency of a Carnot engine increases. Example A Carnot Heat Pump Webheat to the cold reservoir as it absorbed when absorbing heat from the hot reservoir. That is Q h T hw = Q c T cw (4) 1. CARNOT ENGINE - A REALISTIC VERSION 2 so Q c =Q h T cw T hw (5) Combining this with 3 gives 1 T h T hw = T cw T ... The ’ideal’ Carnot efficiency for these temperatures is e=1 T c T h =0:659 (22)

On a day when the outdoor air temperature drops to -10°C it is estimated that the house looses heat at the rate of 10 kW. Under these conditions the actual Coefficient of Performance (COP HP ) of the heat pump is 2.5. e letter words with i and e
