Hi All

Student here just leaning his way i was reading in about T.D i understand it;s the diffidence between the coil & space temp & how it determinants humidity.

but looking a gauges say the A.C stat is set to 24c so room temp is 24C the pressure on the gauges would be 15 bar 217 psi to get 50% humidity 9-12c (17-22% f) T,D if i deducted 12c from 24c= 12c 10.6 bar (153 psi) but i have noticed a lot of r410a lowside are rated at 10 bar max.
and that the usual operating conditions are 110psi-125psi

Hope you guy get what i mean i would really appreciate if any one could point me in the right direction.
