Akula69 Posted July 16, 2009 Posted July 16, 2009 Ok - I'm having a brain fart here...... the A/C lines from the compressor to the evaporator (and back) I know them as 'high pressure side' and 'low pressure side'. which one is the suction line (the high or low side)? Thanks
garmj Posted July 16, 2009 Posted July 16, 2009 Line from compressor to condenser and from condenser to expansion valve are HIGH pressure, the expansion valve converts high pressure to low pressure in the evaporator, making the evap cold then the line from the evap is a low pressure line.Hope this helps.
aemsee Posted July 16, 2009 Posted July 16, 2009 making the evap cold Close. The reduction in heat in the cabin doesn't come from making the evap cold, but from making the refridgerant change state in the evap (from a liquid to a gas) by boiling it. This takes heat energy, which comes from the air passing through the evap fins.

Yea if you buy into what they teach you in A/C school (I am ASE certified in A/C) Just grab a hold of an evaporator when the A/C is running, Its COLD. My explaination was aimed at the layman.Most people thing of boiling as in boiling water (hot) not boiling off to a gas as in Freon or R134a. :cheers:
