That's SS for one nice guy from this forum - Pepinorang ...first He had planned to buy Mach2/Vapo LS, later plan to order 1/3 HP SS from one builder in France and ...finally 3/4 HP (9000 BTU) SS with CPEV from me .
That's first time I've mounted CPEV near evaporator (CPEV outlet is connected by 10 cm, 5 mm OD pipe with evap). In that way CPEV works much better, reaction for tunning is much faster and pulldown time too .
No case, only metal baseplate, my customer said that He'll make case from plexi by himself
Freezepack controller (by GSMaster) and suction pressure gauge, are extras which customer really wanted .
Unit beat mine "old" record with single (-88.1*C) - it has made -93.1*C
Compressor: Sanyo C-1RV137H11AA
evap: steeper by piotres
XV: CPEV Fach "PZ" mounted near evaporator head
condenser: 2 row, alu-cu, cooled by 4*120 mm NBM 12V fans
Refrigerant : R507/R410a blend
Baseplate : 49 x 35 cm zincked plate baseplate
others: REFCO low side gauge, FreezePack controller (by GSMaster)
Suction line together with polish CPEV .
When freezeControler arrived .
First run ...and fighting for the COLDEST temperatures on evap (completelly closed CPEV) . RESULT : -93.1*C
(that's now not WR
, becasue Symphy has beat me with -94.4*C but with single-stage 2.5 HP build by me
On 223W dummyload.
On 202W dummyload.
On 115W dummyload. As you can see -54*C in freezer's limit
. Eg. real -54 = -54 on LCD, but eg. -60 real = still -54 on LCD, -65 real = -54 LCD etc.
Some tests on Conroe E6700es ..4+ Ghz/1.6V = lower that -60*C on evap in full stress
and finally well packed
Happy benching Pepinorang
