When designing a process where gas Chillers/Coolers are used, and when calculating the energy consumption, people have the tendency to use the Chiller duty (say 1MW) as an energy consumption.

However:

- if the chiller is a propane refrigeration unit, the duty to be considered is the energy absorbed by the Propane compressor's driver + lube oil pumps (if electrical) + condenser fans.
Why would we consider the summation of all these duties and not the duty exerted inside the chiller itself(i.e, energy absorbed by propane from HC or the fluid flowing on the other side of the exchanger?

- if the chiller is just an Air Cooler, the duty to be considered is only the energy absorbed by fans.

- if the chiller is just a sea-water/gas heat exhanger, the duty to be considered is only the energy absorbed by the sea-water pump.


Guys, we need your experience... come on![/QUOTE]
