t800's small, cased, daily cascade ;-) | WORKLOG

[piotres]

Hi

Some mounths ago t800 ask me about unit to use it daily. First we had thought about single-stage, we fast we have decided that performance won't be as good as t800 want and with big rotary compressor it'll be bit noisy ...so we decided to built small cascade, in metal case, using 2* 1/2 HP compressors . Goal is -60-70*C@200W .

Specs :

compressors: ASPERA NE2134GK 12ccm 1/2HP x2
evap: steeper evap 40 mm tall
XV: captube 0.8 mm/ captube 0.8 mm
HX: plate HX , 12 plates
condenser: 1.9kW + 230mm fan + 5W motor
refrigerants : R507/R23
oilseparator : HENRY S-5181
safety : RANCO cut-off with manual reset
case : metal case, 55 x 37 x 36 cm, silver paint
others: SLHX on 1st stage, small LCD HX's out temperature display, bitums sound insulation inside case, two 120 mm fans on the back of case + sunbeam CCFL red grills on them











On that photos case in only with layer of premier, no that's not silver finish .

Later I've changed pipes configuration a bit, finally oilsep is before desuperheater .








I plan to make electric wirings during some next days (maybe even today ?) .

I'm waiting for evap too .

Best Regards
Peter
