Ice rink humidity issues
I have a mini ice rink. The dessicant dehumidifier runs too much. I can’t get the RH very low.
Block walls on sides with regular paint both sides.
block wall and brick for front
back wall separates lobby from the rink with walm plywood, batt insulation and vapor barrier on warm side. (Seems to the the job as lobby could be 65 def when rink is 30deg) I have r13 twice and an air space in this 11 inch thick wall)
roof is a black rubber roof with foam board in it.
I just put a low-e radiant barrier foil ceiling the in the rink.
today it was 74F outside, 43F in my rink. Humidity was at 70percent. The dehumidifier won’t get below 55-60 even if I ran it all day.
advice I have been given….
1) get bigger dehumidifier
2) vapor barrier the block walls with liquid rubber coating over existing paint to seal the block. Moisture is coming in through the Porous block
3) spray foam the rinj
4) check for air leaks (I tried a homemade blower door I don’t know what I’m doing)
5) put foam board on the blocks walls and seal it up nice.
basically the ice has been good all fall,winter,spring in Pennsylvania climate. I want to run it in the summer. It’ll get into the 80s and even 90s and humid. I need to lower the humidity in general to 40percent all year round. I put the rink in this December 2019 and have never had it that low.
I’ve been told that the block is porous and the dehumidifier is overworking and it won’t settle down until I seal the building properly???
