Power Consumption

It could be?

K JUST TELL ABOUT THE CHILLER ANG CONSUME THE CHILLER

How rude.

I believe you meant to ask "How to consume conserve power in an AHU (Air Handling Unit)?"

Do the usual things like changing the filters, lubricating the bearings, adjusting the dampers for balanced air-flow, etc. Now if your real question had to do with varying the speed using a VSD (Variable Speed Drive) you should start here and continue to Google for more info, especially since you did not provide us with any really important data such as your location, ambient conditions, size of the unit, why you're asking, existing consumption, size of the conditioned space, etc., all of which determine the right answer to your question.

(Written before I saw the previous post ↑.) But if you're interested in fooling with the chiller, that's another story. Again a lot depends upon your particular chiller and the conditions listed above that you still have failed to provide, but not all chillers can take advantage of the changes that can improve the energy consumption.

From this paper:

"...Not every chiller can take advantage of conditions when a high LCHWT is specified. Four design variables affect a centrifugal chiller's ability to handle low-lift conditions in process-cooling applications:

• The drive design
• The orifice design
• The oil-management system
• The compressor's aerodynamics..."

If you don't know what this all means, then call a competent refrigeration specialist, this job is beyond your skills.

Turn the thermostat up, or down, depending on the temperature.

Turn it on.

You put it on aeroplane and then you take it to AHU
