My christmas snow, with new evap hose.

[froudeg]

Made my own snow for christmas ,

Testing new evap hose on knocked up single stage (this with 120 watt resistive heat load)



~50 watt (uninsulated) load:



Damn good hoses these, from bes ltd: http://www.bes.ltd.uk/nav_graf/frames_cat.htm

Product 14878 1/2" x 1/2" TM x 600 mm fan coil assembly (this is the 450mm one)

Only £5 postage (or free if ya spend over ~£40)

Just cut off the BSP connectors, fit in 3/8" copper couplings into the remaining holes (near perfect fit) and silver braze with some flux..done this with mapp torch, easy enuf with 40% silver rods..they're proper corrugated stainless steel hoses, with stainless steel outer brade. 1/2" diameter is smallest they do, but thats great for good suction line vac pressure, its improved temps by over 10c under load with my ol NL11F prommy comp setup.

Ideal for ppl in the UK, as they know its hard to get hold of stainless steel hoses here.

[berkut]

impressive results. Thats with a NL11 i see, R507 ? What evaportor are you using?

[froudeg]

Stock prommy mach 1 evap, new cap tube hole drilled and repositioned.
NL11F compressor, R404A
Cap line 0.026", 6 foot
Stock condensor (more powerful 120mm fan tho)
Temp probe - Fluke thermocouple, placed on edge of evap, near the surface.
Load - 100 watt, 1 ohm wirewound clad resistor, running at ~120 watts.

The evap hose makes a lot of difference, its running in a vacuum even under heavy load.

from where are u?
wich country?
what condensor do you mean ( u say stock) stock of what?

[Jack]

He toke a prommie apart, judging for the parts used.
so the stock condensor, is the condensor that comes with the prommie

Hmmm I looked at that stuff but wasn't sure if it was corregated steel inner edited cos i saw the one you used 70 bar sweet will give it a go i think how long did it take to deliver??

Yep, its a nventiv prometeia mach 1 - so its the small condenser that comes with that.

I'm from the UK

yes the 1/2" suction lines work very well and the 3/8" copper pipe sliding in snug to brase is a bonus.
i like your heat load.
are you using r404a for refrigerant, how come you used 0.026" for capillary line?
your oc in you sign what cooling system was that with.
you should see some nice results with the new cooler.
