Open air ice rink for Saudi Arabia
(OP)
We are doing a feasibility study for a sizeable open air (without overhead cover) ice rink wher the local ambient temp is up to 35 / 40 degrees. We believe ice has good reflective properties to overcome the intense sunlight and ice has good thermal insulation so that the sunlight will not quickly melt the ice layer. We realize that anything is feasible but at a cost and would greatly appreciate all comments, no matter how critical, and please has anyone any rough ideas on the power requirements per squ mtr for such a scheme We realise the rink need a high surrounding wall to enclose the cold air. Thanks in anticipation C M

Assuming a maximum of 1100 W/m^2 solar load and assuming 10 W/m^2 convective transfer with a -5ºC surface temp and 40ºC air temp, the total load would be about 1550 W/m^2. If the ice is 2-inches thick, the chiller would need to be at -45ºC, which is pretty darn cold.
To make this happen would require enough energy to power around 3000 homes.

You are right with the wall..You can try a wall, say 100ft tall and that will keep the sun out for most of the day....By the way, you are building in Dubai, aren't you?

As I pointed out in my other post, you'd need enough energy to power a small city to make it work.
Working on "impossible" problems got us to the moon (assuming you believe THAT hoax) and potentially can inspire someone to come up with a much more elegant solution than the brute force and ignorance approach.

At the moment we are still not sure if the concept is feasible from Thermal considerations - - maybe radiated heat at 40 degrees will input heat quicker than conduction through ice can take it away - - - we plan to build a one square meter test rig and simulate sunshine with radiant heaters. I will report our findings
Many many thanks. CM
