Hi folks,
I've got a small modular larder with a simple monobloc chiller. The larder is only about 100cm x 120cm x 200cm - not the best picture attached but you get the idea. It's chilling fine and holds temperature well but the humidity is way too high. With the door open and turned off, ambient humidity could be around 50%. I'll close the door and turn it on (nothing inside) and humidity will initially drop during the first cooling cycle then jump to nearly 100% over a short time and never come down - results are consistent across 2 temp / humidity loggers:
I've had 4 different engineers out, probably half of which I had no faith in but the last chap is well recommended and does a few deer larders and the like around here and he's stumped. He's checked everything is running as it should, coil temp is right, no air gaps etc and spent a good bit of time talking to other engineers he knows to come up with an answer.
I'm not looking for suggestions as to what is wrong, but more a favour if anyone has a similar set up (ideally something of similar, dinky size!) with a monobloc and can check humidity in their larder for me. I can post you a temp / humidity monitor to use if you don't mind installing the app on your phone. One of the issues I've got is that lots of folk agree this isn't correct, but no one knows why and no one really records humidity in chiller rooms (it's all about temperature) so there's no real data out there to work with. One option would be to replace the monobloc but no one can provide me with any assurance that another unit wouldn't do exactly the same (other than gut feel that it shouldn't) and I'm not willing to fork out £1500 to find the same problem!
