I know little about refrigeration but I have an ambitious concept, I would like to work ice (artistic work) in the outdoors, but the environment is quite warm, as in 20 degrees C. I am wondering if it is technically feasible to try build an outdoor chiller using a normal monoblock freezer unit. This would obviously be very inefficient but I would like to firstly work ice outside and preserve it for a while.

I have thought this could be done by creating a blanket of cold air above the work area.

I would like to know if any person has thoughts on the practicality of this?

thanks
