    Default Help needed with homebuilt glycol beer cooler, capilary size and length

    Model Number: 0000
    Brand: other
    Age: Less than 1 year

    Hello everyone

    I am hoping someone smarter than me can help me out.
    I have built a home made glycol cooler much like this one. https://www.acbeverage.com/catalog/p...e-13-hp-air-75

    it is using a dan foss compressor 1/3hp using 134a
    it has a 1/2hp condenser with a variable speed fan.
    it is using about 90 feet of 3/8 copper tube in a coil as the evaporator.
    it has a tub of 50/50 glycol water that holds 3 gallons, the entire system holds about 4 gallons of 50/50

    I need to get the glycol down to about -20f to send it to my ice beer tower.

    I need to know what size and what length capillary tube is needed
    and also how much refridgerant should I use.

    if there is anyone out there that can help me out please let me know

    Thank you.

    P.s. I know that in the web page it says .054, @ 112" but this is with a matching condenser. ie. 1/3hp compressor to 1/3 condenser

    BUT my unit is 1/3 compressor to 1/2hp condenser. and I am un sure of the final bath temp in the one in the web page, this is why I need help.

    That would be more of a commercial application. We help people with their domestic refrigeration problems like refrigerators, freezers, AC units etc; etc. Even though the principal is the same it's a different animal. If you can find the guys that do commercial refrigeration like walk in freezers, chillers, display cases, they might be able to help you. Sorry we couldn't be more help my friend.
