Hello There!
In an undustrial environment,when you have a lots of heat, which are the best and the more efficient ways/modes for getting out quite enormous quantities of heat ?

Hi Fellows!
I have a pharmacy lab, which I have to treat in terms of ventilation/hvac.
The substancies which are manipulated in process are
Glicerine´
eters
acetone
benzoico acid
boric acid
borat sodio
tartaric acid
sodio bicarbonat
eosine
etanol

Hello Fellows!
Suppose you have a not so big pharmacy laboratory of a middle technology level.
On account of a manipulation of several quimical substancies in close rooms, which must be ventilated at the regulamentaries air rates.
Do you know which usual norms/rules are applied? What are the...
Hi There!
When I was in the last university year, we use to change a lots of data and at that time I gave a very complete list (without keeping a copy for myself) of heat transfer coefficients in all kinds of heat-exchangers, mainly related to serpentines to heat industrial dying baths.
I...
Hi Fellows!
I have this real case:
Some years ago I draw and have supervised the refrigerating system installation in printing industry (serving as well as climatization system for the office-building) to serve a high rotating speed machine, which has an hot camera/room in its top to dry and...
Hi Fellows!
Suppose a retroffing operation where a common DX chiller is selected to serve in an existingg installation, giving its sensive power at 7 - 12 ºC in the afternoon and during the night (low electrical rates period), working to charge a ice-rink at -6ºC ~ -5ºC for coping the next...
Hi Fellows
Just looking for the best stainless steel choice for springs to perform medium and heavy duty. Please, any guidance will be very appreciated.
Does anybody knows any directory for the quimical and physical/mechanical stainless steels properties, any source, link, site?
Thanks a...
HI Folks!
Suppose an existing church, located at a 40º North Latitude site above, I mean, a building with high and strong thermal inertia/material, and an open space as well.
How do you make an energy efficient approach to choose the type and how to design an proper heating system ? Also, the...
A very classic question: I would like to know what the Forum has to say about the MFHP, (air cooling/heating + hot water production from the same unit/equipment) in special, those with the cooling effect power between 5 and 15 kW (or between 17,000 ~ 50,000 BTU/h). Any related comments, data...

Hi there!
I' doing a survey on air flotations systems in order to optimize ours, which has started-up three weeks ago, (dealing with mixed used-oils/water. It has been working at 92 % of stated project data. I intend to explore all the system possibilities, and the control procedure as well. Is...
