Find out “How Does an Ice Hockey Rink Surface Stay Frozen?” Ice surfaces for hockey are produced and preserved for substantial periods of time without much thought; these two factors are crucial to ensuring good conditions for players during practices and games.
In ice rinks, the refrigerant cools brine water, an anti-freezing agent, which passes through pipes under the ice surface. The steel pipes are usually embedded in concrete slabs and kept at 32 degrees Fahrenheit/zero degrees Celsius. Many thin layers of water are placed on top of the slab to freeze, creating a skating surface.
It’s similar to how refrigerators work to keep ice rinks cold and frozen. To keep the ice at the right temperature, they use a refrigeration system under the floor of the rink, which consists of chillers, steel pipes, and brine water, an antifreeze agent.
Hockey was invented on outdoor ponds in Canada before surface maintenance was implemented, depending on whether the ice surface is exposed to outside conditions.
In Canada, ice maintenance was not a big issue, but in order for hockey to spread to the rest of the country and to the United States, methods of ice creation and preservation were required.
What Is a Rink System?
Rink systems have become increasingly popular in various recreational activities, offering versatile and adaptable spaces for skating, hockey, and other related sports. In this article, we will explore the concept of rink systems, discuss their components, and delve into their benefits and applications. We will also cover maintenance tips and provide insights into future developments within the industry.
Rink systems are specialized structures designed to provide suitable surfaces for a wide range of activities such as ice skating, roller skating, and hockey. These systems offer flexibility and convenience, allowing organizers to transform spaces into temporary or permanent rinks to accommodate different sports and events.
Understanding Rink Systems
The Concept of Rink Systems
A rink system comprises various elements that work together to create a functional and safe environment for participants. These systems consist of modular panels that can be easily assembled and disassembled, providing the necessary framework for the rink. The panels are typically made of durable materials, ensuring stability and longevity.
Components of a Rink System
The key components of a rink system include:
- Panels: Modular panels form the foundation of the rink system. They are designed to interlock securely, creating a seamless surface for skating or playing sports.
- Border Containment: Border containment units are installed around the perimeter of the rink to prevent skaters or equipment from leaving the designated area.
- Cooling and Heating System: Some rink systems incorporate cooling or heating mechanisms to regulate the temperature of the surface, depending on the desired activity.
- Drainage System: Rink systems equipped with a drainage system allow efficient removal of melted ice or water, ensuring a dry and safe surface.
- Lighting: Adequate lighting is essential for optimal visibility during skating or sporting activities, enhancing safety and visibility.
How Are Ice Hockey Surfaces Created?
At the start of the hockey season, an area uses an advanced refrigeration system that pumps freezing water through a system of pipes that run through a large piece of concentrate known as the ice slab. When the ice slab gets cold enough, layers of water are applied and preserved while the first few layers are painted with hockey markings and advertisements.
These layers of ice are then covered with eight to ten more thin layers of ice. When complete, the ice is only once inch thick and must be preserved from September to April or June depending on the length of a given team’s season.
At first, it was very inefficient to create an even-leveled and 200-foot large surface of ice that wasn’t already a body of water. To create the skating surface, the ice is built in layers to make sure it is strong and flat.
After much trial and error, the modern method for creating an ice-playing surface was created.
With two resurfacing machines, it takes three minutes to complete the floor, each making four full passes up the ice. With one, it takes between six and seven minutes with eight full passes up the length of the ice.
Once the ice is made, the ongoing task of preserving the quality of the ice is the maintenance crew.
The arising problem was now to find a more efficient way to maintain the ice surface without using shovels and manual labor.
How Can We Keep Ice Hockey Surfaces Frozen?
Natural ice rinks, like frozen lakes, depend on cold weather. But some artificial rinks have special cooling technologies that allow you to skate on them even when the temperature is above zero degrees Celsius.
Some of these specialized technologies rely on gases to provide heating or cooling properties. One example is the Michigan Tech Ice Rink.
Electricity powers a compressor that packs the molecules of a chemical refrigerant closer together until they become liquid. This releases a lot of unwanted heat energy which is either vented away or used in some other process.
The compressed liquid is then allowed to expand back into a gas. To expand, it needs to take in the same amount of energy as it gave off when it is compressed. It takes energy in the form of heat. The gas absorbs heat from its surroundings, making everything near it very cold.
The chilly gas is then used to cool a liquid called brine. Brine is a very slaty water solution. It gets pumped through pipes underneath the ice rink.
Is There Equipment or a Machine That Helps the Ice Stay Frozen?
In 1949, one of the essential tools to maintain the ice was created called the Zamboni. Named after its American creator Frank J. Zamboni, the Zamboni is a mechanical ice resurfacer. It works by scraping the ice surface and collecting the snow created from the skates of hockey players.
Then, it cleans the ice by putting down water which flushes the grooves deep in the ice, loosening any dirt or debris. The excess water and dirt are then collected, and the Zamboni layers the ice with a small amount of heated water that freezes to make the ice surface smoother.
These large vehicle machines may look clumsy while waiting to start a practice or in-between periods during an NHL hockey game, but it is an essential device for saving time and preserving high-quality ice.
How Does the NHL Manage Zambonis and How Often is the Ice Resurfaced?
The NHL requires two machines (Zambonis) to resurface the ice between hockey periods to ensure time efficiency. The ice is resurfaced before the game, after warm-ups, between periods, during playoffs, and when the game is over.
With two resurfacing machines, it takes three minutes to complete the floor, each making four full passes up the ice. With one, it takes between six and seven minutes with eight full passes up the length of the ice.
The basic driving pattern is a clockwise motion of slightly overlapping ovals. Approximately 80-100 gallons of heated water are needed to resurface the ice between periods.
Are There any Shared Arenas and If So, How Does the Ice Stay Frozen?
There are several shared arenas with NHL and NBA teams both switching the surface level they are playing on. When the arena staff changes the playing surface, the ice surface is always on the bottom.
For example, at Madison Square Garden where the New York Rangers play hockey and New York Knicks play basketball, during a Knicks game, the ice stays in place and the basketball court sits on top of the ice.
Other examples of shared arenas between hometown NHL and NBA teams include the T.D. Garden Arena (Boston), Barclay’s Center (Brooklyn), Wells Fargo Center (Philadelphia), and United Center (Chicago).
You may ask why different sports teams share the same arenas. The purpose is to reduce the costs of the construction of two separate facilities and related maintenance. It is more difficult to transition between the surfaces and other parameters of two sports in one arena rather than in two separate arenas, but it certainly saves more money for the respective cities and people.
Over the years, switching playing surfaces has become less of a hassle due to more efficient technologies and larger team staffs. With that being said, it is more difficult to switch from basketball to hockey because the boards have to be restructured and the removal of the NBA hardwood court must occur as well.
