Low cost, blue chiller (rotary compressor)

Hello

That's very simple and cheap chiller. Based on 6800BTU rotary compressor (quite silent as for rotary) . Owner want to make cost as low as possible so I even don't insulate that unit fully and don't mount pump and reservoir. Owner made that by himself :) .

Plate HX and TXV give quite nice performance. I must add "warm" gases like 134a or 600a to rise temperature :ROTF: - owner want min 0*C in load or warmer.

With pure R507 it can do around -15C @500W tea heater put in 2l of liquid and small pump.

It's rebuilded from chiller which I've made 4 years ago, which stand at shelf in mine workshop since that time (has bad pipe-in-pipe HX which I've scrap). Condensor isn't looking great, because it's from old shop fridge cooling unit :ROTF:.

Specs :

compressor: Rotary Sanyo (remarked) 6826 BTU
heat exchanger: plate HX 20 plates
XV: ALCO TI-HW
condensor: used, with 230V fan , around 1.5kW
refrigerant : R507+R134a+R600a
case: blue wooden baseplate
others: electronic controller ELIWELL EWPC961, REFCO low pressure gauge.

Only around 350W power consumption, when chiller is loaded :up:.

Final charge, 507+134a+600a = around 0*C in 2l of liquid loaded with 500W tea heater .

I can't check how cold it can go without load because liquid freeze in pipes when is pass -25C ...one time I've even seen -32C but that still hasn't the coldest it can go. Crap car radiator fluid even with alcohol mix = freeze after long time of work in -25C.


Thanks
With Kindest Regards

Very nice chiller. Too bad you didn't integrate the pump in the whole assembly as I did. I think it is much more practical! :D

Sweet brazing job, once again! :up:

I can, but owner of that unit want to cut cost as low as possible so he said he'll do it by himself ;). Same about insulation.

good and nice job

Very nice job. If you don't mind could you send me a PM with about how much one of these would cost?

That's 230V^^.

/edit. @Peter

Top notch, as always. :up:

Oh, i was asking about the components used,as i've been thinking about trying my hand at building a chiller.
