    Saturation temperature

    Iam a fooooooollllllll.....???
    What saturation temperature should i maintain on different types of systems ?
    In case of an air conditioner ,
    4.4C is the saturated suction temp.
    So we maintaining the suction pressure to get the proper saturation temp.
    ie R22 68.5 psig = 4.4C
    R134a 35 psig = 4.4
    R 410a 118 = 4.4

    What saturation temperature need for walk in freezer ? (-21C room temp)

    What saturation temperature need for walk in chiller ? (3C room temp )
    If you give the saturation temp. I can calculate suction pressure of different refrigerants .

    Do yourself a favor and post in *F it's what 90% of the users here use, most probably don't want to have to sit and covert it over to answer your question.

    I'm sure its not a joke.

    I can help you, just translate your *C readings into *F and I'll help you.

    In case of an air conditioner ,
    40F is the saturated suction temp.
    So we maintaining the suction pressure to get the proper saturation temp.
    ie R22 68.5 psig = 40F
    R134a 35 psig = 40F
    R 410a 118 = 40F

    What saturation temperature need for walk in freezer ? (-6F room temp needed)

    What saturation temperature need for walk in chiller ? (36F room temp needed)
    If you give the saturation temp. I can calculate suction pressure of different refrigerants .

    The metering device and air flow determine that!

    So on walk in units, you aim for about 10-15*F lower than the box temp.

    So if you want the room temp to be 36*F then look at your P/T chart and find what the refrigerant is 10-15*F below that.

    Freezers are about the same, maybe 20*F less than the box temp.

    Does that make sense or you need more info?
