4.1] A multi-storied shopping mall has installed 5 x 110 TR reciprocating compressors of which four compressors are in use and fully loaded for 14 hours per day. The specific power consumption of reciprocating compressor is 0.8 kW/TR. Due to higher energy cost the shopping mall chief engineer has decided to replace reciprocating compressors with screw compressors having specific power consumption of 0.65 kW/TR. The chief engineer needs following input from energy consultant: • Annual energy bill savings (for 320 days operation). Present unit cost is $ 6.00 per kWh? (show all calculations)

Question
[4.1] A multi-storied shopping mall has installed 5 x 110 TR reciprocating compressors of which
four compressors are in use and fully loaded for 14 hours per day. The specific power
consumption of reciprocating compressor is 0.8 kW/TR. Due to higher energy cost the
shopping mall chief engineer has decided to replace reciprocating compressors with screw
compressors having specific power consumption of 0.65 kW/TR. The chief engineer needs
following input from energy consultant:
• Annual energy bill savings (for 320 days operation). Present unit cost is $ 6.00 per
kWh? (show all calculations)
