DIY Refrigerator/Water Chiller Introduction - YouTube
I will not only introduce you to the chiller/DIY water cooler but also briefly explain how it works. Just to clarify: When I said that there is no other way to refrigerate, I meant that moving heat is the only way to refrigerate, however, vapour compression cooling is not the only option. ...
