My wine room evaporator sprung a leak and the enclosure is rusting out due to the produced condensation - time for a new unit. The outdoor condenser unit spec sheet is below.
Wine room specs:
footprint of room = 15 sq ft
volume of room is 150 cu. ft.
walls 6” studs w/ r19
floor r11 under 6” concrete w/ cork floor @ ~ 1 /2” thk
ceiling = r19
glass in door = 11 sq ft double pane
door = 27” x 8’
Home temp = 75F
Wine room temp = 55F
250 bottles capacity (about 50 gallons, roughly 415lbs)
Cooling load needed based on two wine fridge calculators = 800 btu/hr
So roughly it looks like the wine in a full wine room will rise 2 degrees an hour.
With the thermostat set to 50F off, 60F on, I need to run every 5 hours to cool about 400lbs 10 degrees (4000btu's).
So, in theory, a 4000 btu/hr evaporator unit will run for an hour with a full wine room.
And if the wine room is half full, the system needs to kick on every 2.5 hours to take away 2000btu, so a 4000 btu/hr system will run for 1/2 hour every 2.5 hours.
Is this roughly reasonable?
Thanks a lot, Rob
