At the beginning of the hockey season, the arena uses an advanced refrigeration system that pumps freezing “brinewater” (salt water) through a system of pipes that run through a large piece of concrete known as the “ice slab.” When the “ice slab” gets cold enough, layers of water are applied to it.

How do hockey rinks stay frozen?
How does an ice rink stay frozen? The most common method of refrigeration used in keeping an ice rink frozen is an indirect refrigeration system. This is where a liquid refrigerant (often ammonia) absorbs heat from a secondary liquid (often brine) which has absorbed heat from the source.
How do they put ice down for hockey games?
Layering Ice The first layer is sprayed directly onto the concrete floor, measuring about 1/32 of an inch thick. It freezes almost immediately when it hits the cold floor. Then, more super-thin layers are applied. They are painted white to contrast with the black puck, and lines and logos are also painted on.
How long does it take for a hockey rink to freeze?
MAKING RINK ICE Salt water freezes at a lower temperature than fresh water. This lowers the slab’s temperature to 16° Fahrenheit, cold enough to flash freeze the thin layer of fresh water. (minus _____ ° C) Making the ice for an official NHL hockey rink takes science and about four days.
How does ice rink refrigeration work?
In ice rinks, the refrigerant cools brine water, an anti-freezing agent, which goes through pipes underneath the ice. These steel pipes are typically embedded into a concrete slab and kept at 32 F / 0 C, so that any water placed on top of the slab freezes and becomes the skating surface that we see.
How deep is the ice on a hockey rink?
Ice is approximately 3/4″ of an inch thick and is usually chilled at 16 degrees fahrenheit. The thicker the ice, the softer and slower it becomes.
What does a Zamboni cost?
As the sizes and options of the Zamboni machines vary greatly according to each ice arena’s individual needs, so does the price. The Model 100 (a small tractor pulled unit) may be in the neighborhood of $10,000.00 or more and the full-sized machines can be up to or in the low six figures.
How do they put logos on ice rinks?
One person holds the center of the circle in place while another travels in a circle around them painting the circle. Hash marks and encroachment lines are all measured and painted in place along with the creases and referee’s circle. Logos are stenciled in place and then hand painted.
How do you drain an ice rink?
If your rink is at the lowest point in your yard, you’ll need a pump. To start the siphon, place the hose (garden hoses are easier to use than large diameter hoses) into the rink, then place the other end where you want the water to go. You’ll need to start the siphon by drawing the water out of the rink.
How do zambonis not slide?
The tires have studs to keep the Zamboni from sliding helplessly around the ice. Until the early 1960s, Ahearn said, the machines had sand-coated tires to give them traction. Doing tricks with the machine these days isn’t easy. “Zamboni came out with a new tire,” Ahearn said.
How long does it take for 8 inches of water to freeze?
It takes a minimum of 72 hours at -10 C for 8 inches of water to completely freeze.
What temperature does it have to be to flood a rink?
The ideal temperature to flood your ice is between -7 and -20 degrees Celsius. If you try to flood your rink when it’s below -20 degrees, the ice will be brittle and freeze before it has a chance to level out. Before you flood, be sure to clear off any debris such as leaves or sticks to avoid creating bumps.
How much water does it take to flood a rink?
Your ice base is the most important part of making ice. I find 3 to 4 consecutive nights where the temperature is ideal (this is where weather.com forecasting helps!) and I flood my rink with almost 1/2 to 1 inch of water every night for 3 consecutive nights.
What refrigerant is used in ice rinks?
In ice arenas the ammonia refrigerant is in a closed loop which essentially means it is contained within the system. In most typical refrigeration systems the cold ammonia is circulated or flooded around a series of tubes which contains a brine solution (calcium chloride and water).
How much does it cost to keep an ice rink frozen?
Quite allot, nearly 40000 dollars a month to keep the local one going. They have several dehumidifiers, plus about 70 pipes under the ice, all of which is refrigerating.
How is an ice rink built?
Indoor skating rinks almost always use cold concrete to make the ice. When the rink is built, miles of metal pipes are laid inside a concrete slab. The entire slab of concrete that makes up the arena floor drops below freezing. Then, thin layers of water are poured on the concrete and allowed to freeze.
