Micro_Channel_coils and the proper TXV
Carrier and Trane have published that permanent bleed T.E.V.'s must be install when using their Condensor's with micro channel coils. Trane specs 30% bleed, Carrier specs 5% bleed.
I have a york YC090 split and cant find a spec that says to use a permanent bleed T.E.V.
I have not visited the jobsite yet but sure could use the installation manual and everyones thoughts on this subject.
Im up to speed on the logic behind the permanent bleed valves. Id love to hear how they( Carrier and Trane) came up with their percentages.
any hoo thanks for reading
