An air conditioning system is operating in an ambient of 45°C. The room temperature is maintained at 25°C. Determine the power consumption of the system per ton of refrigeration if it is, (a) air-cooled as in a window-type air conditioner; (b) water-cooled as in a central air conditioning plant. The cooling water from cooling tower is available at 30°C. Assume suitable operating temperatures. Actual COP of the system is only 50% of the COP of the reversible cycle.

2.5 An air conditioning system is operating in an ambient of 45°C. The room
temperature is maintained at 25°C. Determine the power consumption of the
system per ton of refrigeration if it is,
(a) air-cooled as in a window-type air conditioner;
(b) water-cooled as in a central air conditioning plant.
The cooling water from cooling tower is available at 30°C. Assume suitable
operating temperatures. Actual COP of the system is only 50% of the COP of
the reversible cycle.
