H/p L/P switch settings

[Gary]

Hi all,
Just a quick list of approxomate pressures in response to Bernards original post. Obviously these are approx & ambients could change.If i have worked these out wrong can someone let me know

Regards

Raymond

Gas Type, HP, LP@0coil, LP@-10 Coil, LP@-30 Coil.
R12, 118, 30, 17, 1" vac.
R134, 125, 28, 14 , 1" vac/
R22, 190, 58, 36, 9.,
R502, 215, 67, 36, 14.
FX10, 220, 68, 44 , 13,
FX56 125, 27, 15 , 1" vac,
R404 230 , 72 , 48, 14,
R407 220, 50, 32 , 13,
R410 320 , 100, 68, 24,
R507 240, 76 , 48 , 16,

Saturated temperature version of the same list:

Gas Type, HP, LP@32F/0C Coil, LP@14F/-10C Coil, LP@-22F/-30C Coil
R-whatever, 99F/38C, 32F/0C, 14F/-10C, -22F/-30C

1.you take the max avarage ambient for the region,say 35 deg.
2.take condensor td,say 15k.
3.add 5psi for safety
add 1,2 and 3 =35+15+5=55 degrees. this temp should match the pressure on hp gauge.
That applies to all gasses
