[bldg-sim] kitchen exhaust heat recovery -- an aside

[Turner, Stephen]

Martin, Suneel & sim folk,
As an aside, another energy approach we used with success in Florida in
the early 90's in commercial kitchens is to reduce primary energy used
for domestic hot water, and use heat rejection from a cooling or
refrigeration load to preheat the cold water.
Regards,
Stephen

	If anyone has used the GFX heat exchangers, have they
experienced additional clogs in the drain? 
	 
	My concern would be is that if you remove too much heat from the
draining material, the grease component would tend to solidify and over
time could end up clogging the drain after where the heat exchanger
device is installed.  One of the benefits of draining hot water is that
it keeps the grease in a fluid state.
	 
	This could be an over reaction, but has made me reluctant to
offer this as an efficiency option in restaurants.
	 
	Greatly appreciate any thoughts on my response.

		Dear Experts of bldg-sim,
		 
		I am planning to use the GFX heat exchanger in one of my
project.  Does anyone can share experiences of using the device?
