Cool your kitchen with Free AC provided by your freezer. The cooling you get saves you money on your electric bill

About this project

I want to share my problem with a solution. I have no windows in my kitchen and  cooking at my stove is hot and uncomfortable.

Free AC
Free AC

We designed and  built an air conditioner that draws it's cooling from your freezer.

                       Free AC Prototype

Free AC Plate Exchanger
Free AC Plate Exchanger

 It draws about the same electricity as a box fan. It utilizes a plate exchanger that transfers the cold, utilizing a food grade liquid, to a coil in the fan coil. 

Our prototype consists of two components: 

  • 1) A plate exchanger placed in your freezer 
  • 2) A fan coil that blows air over a coil which is cooled by  fluid     circulating through the plate exchanger.

If you want to offset the heat from your oven and stove, and help keep your kitchen cooler, our Free AC will do it. If you have traditional AC, the cooling you get from our Free AC will save you money on your electric bill.

Risks and challenges

We want to be able to manufacture this product as a do it yourself kit that will retail for under $100. We need to set up manufacturing that will allow us to offer a variety of sizes of plate exchangers and sleek, small but efficient fan coils.

Air conditioning equipment is a product of big companies with lots of resources and history, despite this, we hope to create our market by thinking outside the box.

FAQ

  • The plate, with the liquid lines embedded, does not change tempurature enough to make the compressor work harder. This prototype fan coil provides "free" cooling for 30 mins and needs 30 mins to recool, while having the same volulme of liquid inside and outside the freezer. This liquid ratio can, and will, be adjusted (more inside) to produce maximum cooling time for our retail units. Thanks for your input.
