    Dont waste your time chasing every last fps, it doesnt matter in the real world, it wont make a difference, all it will do is cause head aches and frustrations. And dont listen to silly old cunts

    Never heard of it but that's not to say it can't be done. @kiwijames is a fridgy so he will know if it could work. The only problem I can see in my limited knowledge might be that you need an evaporator sufficient enough not to dry out the meat.
    I can't store beer in cartons in my chiller for long because they get damp enough to fall apart.

    But meat is chilled perfectly.

    I wouldn't think it would have the cooling capacity, definitely not to get close to 4 degrees

    It would be a long shot. The AC pump would be a possible but condenser evaporator and all the other items needed would probably make it a no go.

    So the entire setup from a digger or whatever wouldn't be compatible?

    I have the whole system etc

    @Smiddy. You've got the AC pump. It will have a 12VDC clutch to engage so you need both a 230VAC motor and a DC supply = more cost
    What do you plan to use for the evaporator and condenser? The A/C ones are going to be fiddly with 12VDC fans and needing to be enclosed for correct airflow, plus they will be aluminium connections with hose connections so either a hose doctor (with AC connection fittings as they're not standard hydraulic) or some other connection arrangement.
    Actually, to narrow it down to an simple answer. You're pushing shit uphiil
    Message me what you have and I can give you an idea as to what a small fridge system will cost. I'm assuming you have a chiller box.

    I have the complete system from a digger, so compressor, condenser, receiver dryer, and the heater box with the evaporator in it aswell as the fan etc, I have all hoses for the system,
    The 24v supply needed to make these work is no issue.

    I just don't know if the system is capable of cooling a chiller box say 2mx2mx2m

    I have heard of people using a freezer on a timer by cutting a opening in one wall and setting freezer into it with door removed ( vertical one ) and sealing around it and the rest of the freezer in a small covered in area to protect it .then you just have to work out how long to set timer for on off to get desired temp without freezing everything and costing a fortune in power.

    As James said that's the wrong way to go around it.

    Depending on how much meat you want to chill and how often you fill the fridge you would be better off buying an old fridge off trademe. Put a bit of ply on the top shelf with some eye let's to hang the legs from.

    James can correct me if I'm wrong as I'm only an apprentice but I can't see an ordinary fridge not being able to chill a cut up deer fine.

    Just don't pay too much for an old fridge.

    looking for a cheaper way of getting a cooler setup myself ,was going to build one out of concrete block with some sort of cooling unit as wanting to hang a few sheep and cattle beasts as well as anything else I can shoot.fridges are not big enough and heard of a couple guys using freezers on a timer what would be wrong with that? any other cheap way of chilling a meat locker?
