Trigeneration/CCHP

[Terry Metcalfe]

I am trying to do some fact finding on this type of eco-friendly system in
terms of noise sources. My understanding is that the system comprises:

either a gas or diesel engine driven generator inside an acoustic enclosure

dry air cooler

either absorption or adsorption chiller (not sure whether in noise terms
these are significantly different)

adiabatic cooler

The noisiest item appears to be the adiabatic cooler.

Anyone had any experience of these and could offer some details in terms of
noise

Thanks

In almost every case, the designer is at the mercy of the major
component manufacturers for sound power emission data. Generally,
exposed rotating fans, chiller pumps and internal combustion engine
exhaustss including those of boilers are the major noise sources. But
you have to squeeze the data from the manufacrurer often thorough naive
representatives. Good luck and good hunting.
