Like you said, "mechanical engineering" is pretty broad. The only thing I am familiar with is "mechanical engineering" as in HVAC. It has a lot of concepts that you would need to master, but pretty much anything you would be doing has been done a million times and there are rules of thumb and...
There are probably tons of engineers in here who have gone the hard road on this one who can tell you what that is like.
Here is my story. I just got out of the US Marine Corps and met my wife, we got married and all of a sudden I had two kids. I had no college degree, but I needed to get...
Here is the company's link. Hybrid meaning air-cooled / water-cooled unit.

The units are about the size of a McDonnald trash can, have the air intake on the bottom above a water resevoir. The air comes in and moves through a mesh then passes around the coil. The...
Really, a simultanious heating and cooling chiller... I'm going to have to learn about that.
By the way, when you are doing labs do you get into fume hoods? I used to rep Phoenix Controls up in Boston, and half the engineers I knew didn't like how the fast acting valves actually don't...
I just found a manufacturer that makes a hybrid condensing unit that is roughly the same size as a 5-ton air-cooled one for residential and small building purposes, but it claims to be able to facilitate a 30-ton system.
The manufacturer says that it really beats the efficiency of an...
Funny thing. There is a project going on down here in San Antonio called Texas BioMed Phase V. They have a 160 ton VRF system laid out, while at the same time they are very concerned with energy efficiency. It's a big life sciences building.
Thanks for the info, Russ. I really appreciate...
Russ, do you know of any sites that have an energy consumption comparison between Chilled Water systems and DX systems?
I'm sure I could do a study of my own, but maybe you know of a good one that has already been done?
Thanks,

Yuri, I wonder what the numbers are on that. This is my understanding of the basic energy principles for the chilled beams. With a VAV box system you might have a 20,000 cfm unit on the roof that provides a minimum of 2,000 cfm of Outside air. The Chilled beam system would require a 2,000 cfm...
Thanks Russ. So if the building is large, consistently occupied, with reasonably controlled humidity then chilled beams would work well?
If the building is small and has continuously changing occupancy and demands, then out of comfort the VRF system would be the way to go? But you end up...
Are you really trying to figure why you should mist the air, or if you should? Hot and dry climates are practically asking for Water Cooled Towers or at least Hybrid Dry Coolers. But if you have to stay dry, most dry condensing units will meet their rated capacities with 115 degree ambient...
Can somebody give me a scenario when chilled beams would be the preferred method of conditioning and ventilation as opposed to the variable refrigerant flow systems?
I have heard a lot about chilled beams, but I'm not sure they are ever going to really get popular in the US, because I don't...
-Should I become an engineer?
-What engineering discipline should I study?
-Is engineering difficult?
I am not an engineer, but I have been in the HVAC field for 7 years as a system designer, on the dark side as a sales engineer, and now I am putting together a company that is geared for...
Also, practically speaking... the amount of air that you are going to be exhausting with all that stuff is going to really challenge your ability to fine tune the temperature of the space. A shop like that is bound to have huge bay doors that will be opening and closing through the day as...
