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, becau the room is warmer than the water, heat enters the system at a rate of 45 W. If the coefficie of performance is approximated as 2.9, what is the rate of work required by the compresso meet these requirements? T₁,2 = 20 °C T2,H20 = 8°C Troom = 25 °C COPref = 2.9 liters hour Qroom = 45J/S V = 0.4-

Transcribed Image Text: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?
