I've never seen a gravity coil in a wine cellar, there was a company that used to offer them for wine cellars but discontinued it. You need a lot of coil for the space.
you have the unit ducted...

ASSuming 4600 BTU is correct for the cabinet the unit proposed is still large, it is clear your contractor does not understand and I suggest you find a more qualified contractor.

While some manufacturers do use a CPR this is a misapplication, an EPR is the proper choice. However with a properly matched system neither should be required.

agreed. look at a wine guardian D025. Are you sure it maintained temp previously?

Pretty cool. Anybody have one of these? Thoughts?

No EPR and the TXV are OEM and non adjustable.
That seems like an awful lot of filter but since you had it removed that isn't the issue. I have a pair of these that run at 16 PSI, but some fool installed those with about 50' of supply flex :gah:
In my experience those units tend to run very low suction. You possibly have too much ductwork or restriction, very common. Make sure that drain line is not double trapped, not related but I see it...
any pics? what make and model do you have?
Not sure if this is code compliant or not but I've seen installers drill into the floor and drain into the gravel under the slab...be careful of a high water table.
That brings memories of this to mind.

I've seen TXV systems function fine without a receiver but you do need a high torque start compressor is my understanding. I ASSume this works because the condenser coil is large enough, ymmv.
For condensate discharge we use 3/8 pex. Kink free.
I'm a fan of the Bosch core bits like this https://www.amazon.com/Bosch-HC8515-17-Inch-22-Inch-1-Piece/dp/B0000TZYFM/ref=sr_1_2?ie=UTF8&qid=1471276149&sr=8-2&keywords=bosch+2%22+core

Wouldn't an AEV serve the same function? However you must have enough moisture in the air to maintain that 55% which would be unlikely in winter months.
I've seen many compressors killed with the...
That's our typical MO or a ducted system. However a minisplit evap is still the quietest evaporator available.
They still are remanufacturing mini splits for wine cellar applications. Refrigerant is R-22 or one of the replacements.
Outdoor condensing units (MT/HT refrigeration not minisplit) have head...
Have you seen a gravity coil function in a wine cellar? I would think it would have to be huge.
If you need defrost your SST is way low. I believe most all compressors in these units are inverter and need a control board to run.
It would be more expensive, the advantage would be cosmetic and noise level.
There are a few wine cellar manufacturers that use the head units from a minisplit, they however match them to MT/HT condensing units.
The controls are always stripped out and a TXV is added. Most...
How about an ICM head pressure control to modulate fan speed?
A few quick random thoughts.
Is there insulation and vapor barrier in the floor and ceiling?
That's a large room with virtually no thermal mass, 400 bottles? are you sure that seems extremely...
TXV is the same, superheat will need to be adjusted of course.
There is a machine used after surgery referred to as an ice machine. It's a mini comp/pump combo that circulates water thru hoses to a jacket/cuff/etc.

Outside is always best. With that AXV I would add an accumulator to protect against floodback. Did you add a CCH and head pressure controls?
As noted CFM are not designed to move air thru a plenum. Why not just do an outdoor CU?

I think that should be a pretty close match, YMMV.
As noted above WCI is a manufacturer of this type of unit.
I have yet to understand the thinking in using a CPR rather than an EPR.
You are lucky that that head unit is leak free, by far the...
Despite your 21° SH, the frost would lead me to believe it is flooding back.
I'd suggest adding a wifi thermostat so the client will know when the loss of charge is at a critical level and cooling...
Very often those 240VAC head units are connected to 120VAC condensing units, in that setup they are powered off of the 240VAC lead from a MT transformer that is taped at 120VAC. Unlike a conventional...
It may just be overcharged as noted. How long are the linesets? Any vertical lift? While I can't do the math to figure the velocity in the suction line with it being so oversized I wouldn't expect...

In series (maybe the original valve was stuck open?)
Definitely not a DSH.
Liquid line was connected to TXV, outlet of TXV was connected to Evap inlet with a TXV inside.
6000 BTU evap, medium temp, matched remote CU, otherwise a normal system. I'm sure the installer had no idea what they were doing. I'm just curious if it could have possibly worked.
Today I removed a non functioning system, dead comp, no refrigerant, leak lock everywhere and the evaporator had two TXVs inline, one inside the evaporator and one outside.
Could this have worked?
Pump it up with Nitro and check for leaks where the liquid, suction and process tubing is brazed to the compressor.
A few questions.
1. what is the length of the relay cable
2. what is the recommended replacement interval
3. Is this the same as the AG3000 with a relay?
Nice work. Please post pics of those mushrooms.
Why is that? I always carry swiwel T's for this purpose and haven't had any issues.
I have the Bosch sds max which I've been really happy with though I typically don't go past 2.5" for line sets. For larger holes you may be better off with a coring setup. What bits have you been...
I have one, it's relegated to my glove compartment in my car. The way I see it is that it is never the right tool and is conductive.
Welcome to my world :grin2:
We often will add a fan speed controller.
When we need a really quiet system we use an air handler.

I like them on the grill. A quick dip in soy adds flavor and color that cannot be achieved in the quick cooking required.
I called and spoke with them.
