    Hmm True Glass Door Freezer and fridge with remote mounted compressor conversion.

    Hello everyone!

    I'm an equipment owner. I own Southbound RV Park & Cabins here in Victoria, Tx. We have a small store here with a True glass door freezer and a True glass door refrigerator.

    The guy I bought the fridge from had it setup in his store with the compressor setup outside the building. It seemed to work but I only saw it working for a moment. It's another thing to understand if it hold temp 24 hrs a day. Now I have it setup and it won't hold temp. (I've bought temp sensors that send the info to an app on my phone and chart it).

    Then I bought the TRUE glass door freezer that worked well. It made the small store / office very hot and loud so we moved it outside. It seemed to work well for a while in the fall but once the outside temp went up into the 80s or 90s it started to rise inside as well.

    Now that I research it after the fact I realize the units being designed for conditioned space probably wont' work outside without some modifications.

    SO. what needs to be done here? One guy said he would recommend installing a refrigerant reservoir and an adjustable expansion valve.

    Is this possible, have any of you had any experience with this?

    Thank you
    Chris

    It sounds like you already know what to do:

    1) run the units in a conditioned space, and

    2) call a refer tech in to do the work.

    Hmm Other Options?

    Hey Timebuilder, Thanks for the reply.

    Are you aware of other options to make this work?

    I know if I ran them in a conditioned space they would be fine but my lack of conditioned space is what drove them out there.

    I think my objective here would be to determine a way to get them working but outside in potentially 110 degree heat in the hottest part of the summer.

    I agree the finding a good tech is the answer too. I've called several now and can't seem to find one that understands the situation. Or maybe the setup just won't work and they won't just tell me?

    One said that a reservoir and an adjustable expansion valve would do it but now I can't get a hold of the guy.

    I've looked around online and can't seem to find anyone that has done this. Maybe I'm just not using the right keywords in my searches?

    I don't think modding the units is the answer. Restore them to the design and use them as intended. Or, replace them with working units.

    You can have someone experiment, but I work on these all the time, and I don't think an outside the box approach (pun is intentional) is really the way to go.

    Good luck to you.

    Thanks for your thoughts on that.

    What are all those units I see out side of small stores and gas stations etc? I thought this was more common.

    Without knowing the exact details it is hard to tell but I'll take a stab at it.

    The True units were designed as self contained with the minimum HP needed and a cap tube metering device. If you wanted outdoor equipment then new condensing units would have to be purchased with weather tight enclosures and low ambient controls along with fitting the equipment with x-valve metering device. Quite a lot of $'s but if done properly worth every penny.

    That would require individual analysis.

    That said, outdoor coke machines are designed to be outdoors. Coke also has cases...made by True...for use inside stores.

    PECMSG,

    Thanks for the reply. You seem to have a good understanding of what I need to do here. I expect this to be costly but it's a choice between that or a larger AC system for the office and the electricity to remove the excess heat generated for the life of the store.

    IF it helps. my true freezer is a GDM-49F and my cooler is a GDM - 72..

    Is there a company that sells something like that that I could have installed to fix the issue?

    Ask family, friends, others in buss you know and trust. Easy to do it right …………….easier to screw it up!

    PECMSG,

    Somehow I think you're under the impression I'm trying to rig something up or do something cheap. I reached out to this forum because I had hoped to come across some professional willing to offer some direction on this project. I thought the person that installed this for me had the knowledge to install this and could be assured of it's reliability but I see that there was an oversight. I see convenience stores all the time with small units outside presumably cooling units on the inside for various purposes. If anyone has knowledge as to how this should work please let me know.

    I fulled expect to spend some money getting this done but a reliable solution will keep me from having to oversize the AC in the store and will save me money on electricity for years to come. Whatever the cost now I'm sure I'll get it back in electricity savings at some point.

    I would have to be there, and since I am not, you would have to call in a company to give you options based on what they see, which includes condition, and how much of the unit design was changed by others.

    I wish I could give you more specific advice, but the units I work on are strictly OEM design condition and repair parts. Your outcome is going to depend more on what is there and what can be done with it.

    These units are designed to have their condensers inside.

    My customers are VERY cheap, and only a new store gets a different brand and outdoor condensing units, which are actually more expensive, but more durable.

    So, there are too may factors to make a judgement from here.

    I hope it all works out for you.

    If you don't want to do remote. Just get a low cost mini split and hang by the boxes and let it move the heat outdoors.
