Reply With QuoteThanks guys,so they look OK.
Yes, ball valves would be convenient, although I could put one between the 1/4 flare end and hose line if I wanted.
I always use one on the end of my HP line, but its worn out and needs replacing.

They didn't come out very well. I'll try to do better, in the daylight, tomorrow.
If you don't like trucks, stop buying stuff.

Amazing how as kids our parents would admonish us for nagging, sooking and pestering.
Only to continue such behaviours as grown adults.
Cynical Moi?
Normally Randy, it should be calculated into any system that incorporates FAM, (Fresh Air Makeup) in it's operation but not all do, to keep the price down. Silly buggers.

It takes all sorts Mike,& I don't mean the licorice confectionery. Well, maybe if one bribes them with those one could be on a winner.
But in reality some business do take the urine.

Paul performed his magic on my car this morning, regassing the air conditioning. How cool is that?
Thanks Paul, it's good to put another face to a name.
I meant to show you this and ask if it interested you.

I wonder if he looks anything like my version in Minds Eye?
6', Long Blonde hair, long legs, curvy waistline, for
workboots he'd have 5" stillettos.
Bugger, getting carried away again.

I think thats Ian you are talking about, not me.I wonder if he looks anything like my version in Minds Eye?

Yer good to put a face to a name.
Couldnt find any leaks so the guy who put in the parts did a great job.
Hopefully the AC job will be the last for the life of the car.
I was gonna ask Rick,if the dryer is about 2/3 the size of the original one, no sight glass, charge is 780GM,i put in 700,all seemed good.
My guess on the quantity will be OK?
Pressures seemed OK,although difficult as they go up and down with revs, return gas temps seemed good as well.
Those Stradbroke pics are good.
We used to call those old crane trucks Blitzes,when I was a kid, they were used on Fraser a lot as well.
As I said on another thread a while ago,i remember one pulling a well drowned Series 3 out of Elie Ck,with another Series vehicle hooked to the front of it to stop the front wheels being lifted off the ground.And then towed it down to Gorden Elmers barge.
A trip to Annand and Thompson(Brisbane LR dealers at the time),and it was all fixed, back on the road in about a week.
We renamed it the 'Yellow Submarine'.It was brand new at the time, still had the bit of cardboard taped to the back window, running in, please pass.
It was my fathers company vehicle,the last LR they ever bought,in came the Toyotas.
It was well modded, winches,bars,long range water and fuel tanks, racks,shovel and axe on the top of the front wings,etc.

The big issue with introducing more fresh air into large systems is the extra load on the AC.
If you used the %'s of fresh air health experts are advocating we'd have massive AC systems with huge electrical and therefore CO2 loads.
Current systems wouldn't cope, and I know building owners wouldn't stump up for the extra capital cost and power usage.
Most large systems, e.g. department stores and shopping malls and larger office buildings with large air handlers or central plant or even larger pac units have an economy cycle that kicks in If ambient conditions are conducive.
Various %'s of outside air are introduced up to 100%, but it's a pretty narrow range of outside air conditions that can be used.
Think of spring and autumn as being ideal for economy cycle conditions.
Back in the day the standard was 10% or I think it was 7l/person/minute? outside air introduced at all times in a commercial building but now we base it on an algorithm of outside air, inside air, outside and inside RH and inside CO2 levels measured in various parts of the building.
Generally 600-900ppm is the setpoint for CO2 before the dampers start to open and introduce fresh air. On ridiculously hot days I sometimes override that to 1000ppm to reduce the load on the chillers if they are old and struggling. IIRC 1500ppm is about the limit before people start to get affected and concentration can start to drop off.
RH levels used to be and are mostly still 55-60% as the optimum but this is starting to change to 10g/kg moisture content so that higher setpoints and wider deadbands can be used to reduce coolng costs, some sites are now using up to 26° with 10g/kg moisture content but staff and customers aren't happy.
Situations like hotels are pretty well sealed, so rooms have individual fan coils and only a fixed amount of outside air is introduced.
I was in a new 3 storey police statation yesterday with a setup like this.
Multiple VRV's with I think 70+ FCU's, a combination of cassettes and split ducted systems and just four fixed speed outside air fans pumping fresh air into the space.
The exhaust fan in the drug room failed and everyone on the first floor ended up with a cannabis induced headache.
Increasing fresh air in buildings isn't easy or straightforward, it's already very finely tuned to achieve optimum building efficiency from an energy usage POV.
