And now for something a bit different.

[sacha35]

Well guys as you probably know I have not been about much with benching and stuff , as most of you know I have been working hard learning and building some phase units with 4Qman, well this is my latest project, it’s a lot bigger and much more different than the normal units we all see, My thinking behind it was to have two condensers with the fans blowing from either side to try and keep the compressor nice and cool as you will see I have made a nice small SLHX and hope to have the unit running a mixture of R402a and R410a which will make things run that bit hotter than normal.

The unit is not finished yet as I am still awaiting Chilly1’s new evap, once this has been fitted and pressure tested I will then do some more paintwork to the compressor and some pipe work.

Anyway that’s enough waffle hears some pics.

Thanks for your coments K404 and i do agree with you 100%,

This is why I have installed the wiring to 16th edition IEE regulations, thermal and overload circuit protection has been put in the wiring loop together with 4mm earth bonding, being an Ex electrical engineer with C&G 236 parts 1-2 and C level together with Electricity board 11K switching Cert, this is something I am very strict on as current is a killer, as for qualifications The unit will be filled by a qualified refrigeration engineer once it has passed his pressure testing.

wow dude you have just moved the bar higher

cant wait for the load tests

Thanks for your comments baz, without seeing your posts and encouragement I would have not even started the builds, as for the load tester I am building a nice big 500watt full adjustable unit that can be controlled to whatever amount of watts is required up to the limit of 500watts of course, this will come in very handy for when 4Qman and myself start the big boy cascade.

you might want to try cold ice for an evap they are the same as a chilly more or less and he can have it over in 4 days

Agreed Cold_Ice rules. So glad you recommended him to me Baz, i got my box of goodies in under a week from him. Time to plan and prepare for the build.

Sacha, again looks superb. Quality and attention to detail is best bar none.

Oh agreed also K404, my uncle and friend are both air-conditioning engineers so that side of things is as good as they come . With Sacha and his electrical background means that these builds are probably one of/if not the safest around.

Glad to see this on the net, thought it wouldnt ever be showen

Thanks 4Qman, i would not go as far as to say this is the best or safest unit around, I think Phill sell's great range of products with attention to detail second to none and with a full back up service if somthing were to go wrong, this is just somthing that i take a lot of pride in, coming from the background that i do everything has to be right or it could cost life's, i guess i just look at this with any work that i do, in that i mean it has to look right and perform right too.

Well guys as promised I have finally sorted out the S/S unit and have some temperature results for you all to see, as you can see I have used my load tester which is within +- 2 watts and the fluke is also within +- 1c, so after other commitments and a few problem of which are sorted now here are some pics for your viewing.

-68c, First run up know load, very small amount of flood back at compressor, 5 minute run

50 watt load applied, -54.5c, know flood back at all.10 minute run

151 watt applied -51.5c,1 hour run

254 watts applied -48.1c,1 hour run.

272 watts applied -38.4c,1 hour run.

282 watts applied -32.3c, 1 hour run, this was the limit of the unit as when i tried for 290 watts it started to drop below -20,

Then back to the start again with know load, notice that this is slitly higher then when i started as the unit is very hot now. -59.5c.

That's really impressive,280w on a single.Nice build too.

 

[sacha35]

Thanks Thickbrit, it is all down to using a SLHX , twin condensing units with fans and a blend of refrigerants that make this unit perform so good with low pressures on the high side.

 

[sacha35]

OK Guys as requested some more pics of the finished item, one question for you guys now, what do you think is more important to you, out right performance from a S/S or looks or both.

Thanks again for your coments.

I haven't seen one like this before, it's stunning - a very nice job

I think that looks, sound level and performance are all part of a balance with these things...
