Hi guys,. I have a location under the stairs that is very small, it's accessible through a large 250 square ft bedroom in the basement I use as a gym. I can build a design to hold around 500 bottles or more, however it would be nice to have it cooled. At any rate I can't vent anything to the outside so if I installed a portable Air conditioner it would vent to the bedroom...essentially a large fridge. I suspect that it would hardly run since the area is 68deg in the summer. Is it safe to vent in the bedroom? And also would I notice the temperature get warmer in the bedroom?
