I have actually seen a situation when both parties paths cross in an airlock & while holding both doors open then proceed to have a very long chat.

Most older buildings were designed and built before all these sorts of issues were thought of.Many commercial buildings are insulated,in the ceilings, with the modern ones having to comply with latest regs.Quote:

Schools are a real issue, most were not designed for AC units,only the newer ones seem to have insulation in the ceilings.
This Qld Cool Schools program is just throwing thousands of AC units into schools that were never designed for AC units.Nor was the power supply.
Air locks do help, but in a high rise building,the amount of cooling not needed,or saved, due to an airlock is a drop in the ocean.
Resetting the zone set points 1 degree higher in summer, and a couple of degrees lower in winter is the way to save power.
Many buildings and shopping centres do this.
Economy cycles, as Rick has mentioned, also work very well if set up properly, and all the dampers,relief air fans, etc,work as they should.
This equipment needs constant maintenance,and repairs, which is neglected on many sites.
A couple of years ago, we picked up a site, and found over 50 fresh air, relief air, and smoke spill dampers that didn't work as they should.
Actuaters fitted by another company were incorrect, and many dampers were seized.
Mandatory fire tests were never done.
When the building owner wants to save money, repairs just dont get done.
A certificate will be coming through that I've met the NSW TAFE certification for the safe use of hydrocarbon and CO2 refrigerants.
I must like to live dangerously but I'm very eco friendly [emoji23]
The one course?
Here in Qld,its two different courses.
The boys have the hydrocarbon sorted, but not the CO2.
Although I asked them to see if they could get a capillary chart for the hydrocarbons, no such luck,didnt even have a PT chart[bigsad][biggrin]
We did eventually find a PT chart on google, but no capillary chart.
How have you managed up until now, pure arse? [bigrolf]Quote:

As the TAFE teacher said, govt hasn't caught up with the changes that the world at large are going through yet.Quote:

So far I've just refused to do things I wasn't comfortable with until I formally knew the ins and outs, and I haven't had to change components or add refrigerant to a CO2 rack yet, just fault find electrical and control problems and kick any component problems to techs that had some training.

Was having a chuckle with 'er indoors yesterday re your recent comment about "Up to the armpits in Alligators".
We did have a good laugh Rick because she could relate to that situation. Thanks.[bigrolf]
