Re: A/C Systems
 

THis is still wrongfully worded :

'In an expansion valve air conditioning system, refrigerant flow to the
evaporator varies according to the pressure in the suction line
(evaporator outlet). This is detected by a sensing bulb mounted on the
line, and relayed to the expansion valve via a capillary tube
'
