    If you look at the first picture you can lurk it out what components the second cascade uses. If you don't know what those parts are you obviously shouldn't be into cascades. (bad english)

    A subcooler is an HX used for lowering the temperature of the liquidline and raising the temperature of the suctionline in other words cooling the superheated gas/liquid in the liquid line..
    Used to make the system more effecient.


    I edited the posts for the desuperheater that is actually a device that is connect after the compressor to desuperheat the discharge gas from the compressor..

    What you are describing is a subcooler. A desuperheater lowers superheat, which this does not. This in fact adds superheat to the suction vapor. The vapor/liquid mixture in the liquid line is subcooled, not superheated.


    Thx Gary missed the error...

    He's from the city that never sleeps.

    I'm still trying to figure out what a CPEV is. As near as I can tell, it's an AEV.

    Ya the strangeness has something to do with all the flashing lights and noisy buzzers, I think. Either that or Fugger keeps him up all night wanting to see that Ultimate O/C.

    They say it's the heat ... working on rooftops for the last nine years in the summers and temps around 140 with the rubber of your sneakers melting away in two weeks or less...

    If only we could all be so lucky... I feel for you guys down there.

    140F... Do you guys get alot of blow offs from pressure reliefs or by passes opening up?
    I'd be afraid to even carry around refrigerant jugs. I've seen an old boss of mine do that.. /rolls eyes.

    I used to be very afraid. The iside of the van parked could reach 150F But never a one... Some guys who over charge the recovery tanks get a blow off or two. and you hear of someone not tying their tank down and it blew in the truck but not much...Mostly wear out shoes and drink way too much water ten 2 liter bottles a day plus what I drink at home.. At a minimum... We get a hugh number of burned out condenser fan motors with this heat they operate about 10 degrees above their maximum temperature. Even the new R410 systems dont have trouble.. The head is a little high at 550 psi discharge, but it appears to work ok.. So this is for all the worriers about cascades out there the cascade systems we build the head pressure seldom exceeds 300psi...

    Nice, so with this system you can run 24/7 at around -50 and them drop it to -100 for benchmarking?

    Not really if you build a chiler that is an option. with phase change a Temp range of -70 to -100 is possiable. Fractional HP compressors don't have unloaders..

    Ok, but is -70 ok to run 24/7 and safe
