Back in November , I catch Brian from Studio 33 setting up the outside ice skating rinkin Folsom .
His bunch was painstakingly inspect a series of tubes moments before they began filling it up with liquid refrigerant . They are on their knees on the right hand side of this photograph .
Here comes the red propylene ethylene glycol .
I asked him some questions about the engineering involve . I did n’t realize that the skating rink was a rare contour , a circle . Typically skating rinks are long ovals , tolerate some dead blank space , center frosting , for experienced skater to hear their leaps and spin . The circle meant that he ’d had to re - configure the typical plumbing layout used on outdoor , artificial ice-skating rink rinks .
These white spacers kept the tubes asunder and kept them from resting on the airfoil plastic .
The methamphetamine was to be kept frozen with very cold liquid flow inside the tubes . There was 40,000 ft of tube in the skating rink , occupy with 1,620 gal of water mixed with propene dihydric alcohol to a 35 % solution . These were the numbers off of the top of his top dog , but 5 ounces per foot of tube sound about right to me .
The rink space had been ready with ducting which range under the ring of the rink .
One of these 8″ tubes was the route from the truck , one was the path back to the truck .
The icing skating rink is bear out by two large motor mounted on trucks . One is the pump , and one is the freezer . The pump push the coolant around the tube at about 70 gallons per minute . That means that the entire volume of coolant can be recirculated every 23 minute . The tank is ready to keep the fluid between 14 ° F and 22 ° fluorine .
One of the engine is a 275 amp , three phase motor . I think this figure was for the compressor for the Deepfreeze , but it might be the ticker .
Soon afterwards , the ice chest was lead , and the surface of the orange tubes started to pull in condensation and stop dead it . I snap these picture days afterwards , so I do n’t know how long it took for them to stop dead up .
The ice skating rink in operation , on a Monday afternoon .
Here is a side perspective from outside the skating rink . The ice await about five inches thick , but some of that is probably a layer of styrofoam insulation . The chalk has to be thick enough to support a small Zamboni , one of those ice-skating rink - smoothing tractor .
It was a fairly simple concept — just in a distinguished scale . It worked well !
