Richard, what you're saying is true, and i use that effect to in my chamber, but that is only true for "frost-free" fridges. These mini fridges use cooling coils, meaning the humidity that is in there, stays in tehre, and never gets pulled out.
Since one shouldn't be seeing a lot of *frost* as such at 15C, I think the requirement would be that one had a condensate drain, or other means of removing it (air change or even a sponge).
If only it were 'frost', that would lock up the excess moisture.
I can recognise that a humidity controlled, moderate temperature enclosure would be of great interest both to home charcuriers and home cheesemakers, but I'm not sure that even the combined market at the likely price, (I'm pessimistic), could justify the costs of productionising a special enclosure. The higher the price, the more an already small market is restricted and the higher still the price must be set to recover the development and fixed costs.
I do however wonder whether or not a 'control pack' might be a more viable product.
Such a pack could then be applied to whatever fridge was available.
By leaving out the enclosure, the whole compressor/evaporator mechanism, and having a smaller product to stock and ship, it should be much more affordable - and hence have a larger market.
I'd like to see
- everything inside the fridge being low voltage. Thats humidifier, fan and controls.
- a "mains power switching" box outside the fridge. (And do me a favour, allow it to work on 240v at 50 Hz, please!)
- And please can I have an LED panel on a ribbon cable to come past the door seal and magnetically stick to the outside of the door or chest freezer to show me cooling, humidifying, and fan activity? (And a flashing low water level warning for the humidifier.) A readout (with max and min stored) of temperature and humidity would be very good to have on that panel too.
Would it be a good idea to make the pack fit into the fridge door? That would minimise the useful space taken up, and might make for easy attachment to removable (potentially replaceable) plastic shelves.
Oh, and by allowing it to control a heater (rather than a fridge) it could possibly be sold to reptile keepers as well.
I've got a feeling that if the exterior temperature gets too low, (like in a garage), then the cooler isn't going to be called on, and hence the cooler isn't going to function as a dehumidifier.
And with the same actual moisture content in the air, allowing it to get "too cold" is going to also increase the relative humidity undesireably.
Probably the way round this involves a heater, perhaps a repurposing of the fridge's existing interior lamp - although the simpler, if counter-intuitive, answer would be to keep the curing fridge in a room that was always above 15C... ! (Though clearly this wouldn't be a problem in Tristar's location... :D )
