Topic tags/keywords: peltier cooling thermoelectrics kitchen remodel question

Hello All,

I have a technical question about a refrigerator I would like to build for my kitchen remodel that I am beginning the planning process for. I have a small kitchen and was thinking of building a fridge into the cabinetry instead of purchasing a stand alone unit. Many years ago the fellow that got me started working in mechanics build a cold room for his house which his wife absolutely loved. He used the traditional Freon compressor heat exchanger units but I would like to try a Peltier thermoelectric unit. The first, of probably many, is how do I size one to be suitable for a given space? They appear to be rated in watts of cooling, a voltage and an amperage, how do I compare watts of cooling to BTUs or even better how do I understand what 800 watts of cooling would do to a bar fridge type space? I have just heard about these devices and know very little about them and was puzzling about this on the drive home tonight so I will probably have a lot more to figure out once I start learning about these devices. Any insight, help or direction to resources would sure be appreciated. I am of course scouring Google to learn what I can but sometimes it is nice to hear from a real person who actually understands these things!

Thanks,

Mark

I would contact a local refrigeration contractor/installer/commercial repair to get that type of info.

So based on this article, seems like Peltier coolers aren’t going to work for your freezer portion. What are you trying to accomplish by going Peltier? As someone who’s got any number of home-scrounged systems which require way more strange maintenance than they should, there’s a lot to be said for off-the solutions…

Thanks nightguy, I don’t think I am ready to pony up any cash for this idea yet so I’ll save talking to the pros a little farther down the road.

Dan I have this idea that I could make a bar fridge size fridge to hold about a weeks worth of cold things. I live 5 minutes from a grocery store so I don’t need to hoard food and the fridge I currently has is stupidly huge and takes up a disproportionate amount of my kitchen. I had initially thought I may go the traditional compressor route (and still may) but I ran across these thermoelectric devices and the design challenge appeals to me. Frow what I have been reading since my initial post I don’t think its an affordable solution but I will keep looking. Thank you for the link.

Do you not have the room for a small portable refrigerator like the type found in school dormitories?
