one long week end

[kayl]

about 14 degs C the condensor is cold, im using 120CM^3 fans AC X 2

[Gary Lloyd]

What is 14C, the air entering the condenser or the air leaving the condenser? What are both temps?

[kayl]

this is the final room temp, res temp,and pressure also, i cant measure the air temp entering and leaving my gauges arnt really set for that.
its been in the -19-23 degs C range now for a total of 5 hours now. i think if i was to put it on the computer the way it is i might gain a few degs.

also gary i could say that my condensor is at room temperature at full load, so the air going through it would be around room temoperure, the airconditioner cut down 3/8 condensor has a very large surface area

i think the pressure is about 8PSI LOW and 143PSI or so hig side.

[Gary Lloyd]

I've lost track. What compressor are you using now?

[kayl]

the chillier that had the 130w load and pump was using a compressor out of a 6,500BTU airconditioner, old R22 one

[kayl]

and this is another chillier i made today with a smaller res. not insulated that well yet, burnt it by accident with torch
the pressures are 5PSI LOW and 155PSI high.
its about a 1000-14000 BTU compressor out of a large fridge freezer and uses 384W

[kayl]

i think i know that my thermonitor is acurite because the bottle pre mix coolant that i used says good to -37C and when i put it in my first chillier i added a little straight mix to give -38.4C
so far in the last three systems this is the lowest temp i have been able to achive with no load.
i think i have finally found a source of copper in australia, its a place in melbourne i got a return email on prices
i think i might made a direct die using my small 3/8 copper condensor and my small 1400BTU nitrogen charged compressor
it only uses 355W and it can hit -38C on a chillier so i think it will be in the -30's under load

[kayl]

i got my lowest temp today, i was running the compressor with about a 3PSI vacuum. after 1.5 hours the almost the hole res has frozen over.

[oc_nightmare]

try to make a tap for the res and ull see better temps

[kayl]

thanx oc_nightmare.
i think im going to give up on the chilliers.
my pump is playing silly buggers, and finding one that will handle those large temps overtime with out cracking will be hard and costly.
and i still cant find denaturised alcohol in Australia, so the coolant doesn’t thicken up, and get hard to pump, and freeze on evap.

at the moment the pump has stopped pumping, so i pulled the res apart, pulled pump apart and put it back together, the it works. put it back in the res and its not working again. so i pulled it apart put it back together and checked that its still working then put it back in the res and it stops working again.

i can hear it pumping but no liquid comes out.

but the good thing is that i have placed an order for 8 pieces of 600g copper blocks, 50mmx50mmx25mm and i will be making a maze design copper block and trying my luck direct die.

[kayl]

something that normal ppl would find useful

all i need now is a stuby holder to fit over this

Sounds like you are trying to pump glycol based anti-freeze. It gets very thick at low temps and is near impossible to pump. You need an alcohol based anti-freeze, such as de-natured alcohol. It can usually be found in the paint department. Or you can use automotive gas line anti-freeze, which is methanol.

[kayl]

what about metholated spirits, or thinners.
thats the only thing i can find at the paint shop garry

[Gary Lloyd]

Read the labels. What does it contain?

yea, if u have enough tools and knowledge in the phase-change physis i think u really should give a try to get in a direct die system

good luck m8

[kayl]

sorry garry is doesnt says what it contains,
its just mineral turpentines.

i have been dying from day one to make a direct die just that i couldnt find copper blocks anywhere.
i am ordering the copper from the other side of australia, and its taken a few months of looking around to finnally get anywhere.

[kayl]

i just finished my latest batch of coopers beer and for my birthday my wife got me a set of scooner glasses

could u show a pic of how did u shoved a shradder into the gas hose? im going to do the same for my direct die but ive no idea how to do it

SORRY SO LATE
never actually got around to taking a pic for ya
here it is

[kayl]

i ran out of r290 today
so i grabbed the bottle of the barbeque
this is a 8.8kg bottle
just a few charges here
maybe a few hundred systems i could fill

its 96% ethanol is this ok for pump seals and things.
or do i need menonal

[Gary Lloyd]

Ethanol seems to work just fine.

[Tonic]

By the way, what's that 4% in kayl's alcohol? Water or some dirts?

[Epsilon]

some methanol probably + some water

[kayl]

not sure sorr, is ok on the orings in the water block
or is glyco better on the orings?
