Consider a facility with a staff of 20 people that require cold drinking water each day. Each person consumes 0.4 liters of water each hour. A refrigeration system is used to cool the water, and is placed in a location in which the surrounding air is 25 °C. Furthermore, because the room is warmer than the water, heat enters the system at a rate of 45 W. If the coefficient of performance is approximated as 2.9, what is the rate of work required by the compressor to meet these requirements? TH2 = 20 °C COPref = 2.9 %3D TH20 = 8 °C liters V = 0.4 hour Troom = 25 °C Qroom = 45J/s
