Yes, the building for the moment is completely empty (absolutely nothing inside - highly conceptual at this stage). However, the next step probably will be assessing the energy required with trays of compost and other furniture inside.
How would this effect the energy consumption and how can I...
Hi everyone,
I have a question about energy required to heat an insulated building (completely empty) using two 50 HP diesel boilers.
The building is a mushroom farm with no internal loads, and insulation on walls and roof. Steam is directly introduced into the space with temperature of...
I too agree with the statements made by JMW, they are certainly true for "today". But "today" is not going to last forever, the design process will have to change.
I don't think many engineers are following through with their designs. By this I mean that we engineers stop the design process...
jmw,
In today's market what you say may be correct. But that does not mean that engineering in the past has been like that or in the future will be like that.
I can't imagine the Wright brothers applying a market based design to their aircraft. Nor can I imagine the first manufacturers of...
What is an Enjuneir(sic)?
A person who can see the future and navigate the most efficient route to get there because he has at his disposal a tool called mathematics which he can be applied to anything and everything in the universe.
In a world where only pretend engineers are available...
Hi again all,
I came out of a meeting with one of the biggest developers in Australia (Multiplex Constructions) yesterday where we presented the developer with a brand new idea which was originally researched and developed by NASA to remove Volatile Organic Compounds (VOC's) from air.

ChasBean1,
I think we have indeed come across the same info in ASHRAE but mine is in SI units...bout time you guys upgraded to SI as well...:)
Anthonyd,
Yes I think it may be an engineered solution suitable for our project only. The alternative was to use smoke curtains in front of elevator...
TomFitz,
Look up my post in Multile Cooling Towers/Chillers thread. I think this may apply to you.
Some Trane chillers do not have oil pumps and are driven by a pressure difference between the evap and cond of 280Pa. Anything below this for 2 minutes will trigger alarm and shut chiller off...
Although I am an engineer, I cant get myself to agree with what most of you are saying about tradespeople earning more money and driving SUV's. Lets face it, how many of you would like to look at your future and feel comfertable with how it looks knowing that you will be laying bricks for the...
Lift shaft pressurisation was one of the cheaper options presented by the fire engineer. He referenced Table E2.2a of the BCA and of course AS1668.1.
The other alternative is to install a smoke curtain on the elevator door on just one of the levels. Sounds easy until you try to contact...
Hi everyone,
Just a quick question on lift shaft pressurisation during fire mode.
We need to pressurise a lift shaft to between 20 - 50Pa only when there is a fire (as per Australian Standard 1668). However, I need to know the quantity of air that is required. How much air do I pump into the...
Hi again everyone,
Firstly, my apologies for my late reply and being such a bad host!
Secoundly, our unofficial company moto is:
"Would you rather have X amount of dollars hanging on the wall or in your pocket?"
This is how we approach our design, BARE MINIMUM, and I work for one of the...
Thank you Mark62...I did a little more searching on the net and finally found the site I was looking for:

It was posted on one of the other threads...I checked out your site as well...very helpful...much appreciated.
Thanks,

Hi all,
I have been working in the HVAC design industry for the last 3 years only. Before that I was woking in an industrial environment which is totaly different to what I do now.
Over the 3 years I have come to the conclusion that the HVAC industry is extremely primitive in dealing with...
iken,
Don't quote me on this just yet but it sounds like you may have differential pressure between evap. and cond. sides of the chillers.
Some chillers do not have an oil pump and therefore rely on a pressure differential between the chiller evap. and chiller cond.
Usually, a 280 kPa...
Hi everyone,
My apologies to everyone in this thread for the question I am about to ask.
A short while ago I came across an internet site through (from memory) eng-tips, which gave a list of job opportunities in the oil & gas industry. The site was not a headhunter or recruitment company site...
Hi all,
Some pretty good enjuneirs around these days...
I started my career in one of the biggest family owned companies in the world. I trained as a project engineer and was sent to turkey to supervise the construction of our new $US90 million processing plant.
Best experience ever, can't...
