RECORD-BREAKING ICE
SPEED AND EFFICIENCY

COINCIDENCE?

From 2019 to 2021 EKA was involved in the project team of the National Speed Skating Oval (aka Ice Ribbon).

The mission was to develop the first speedskating ice arena with natural refrigerant CO2. One of the project's main focuses was ice quality - by maintaining a very precise ice temperature control,

This Olympics ice has brought 10 new Olympic records in speed skating competitions.

55% efficiency increase

Seems too good to be truth.

 The latest follow-up on a renovation project EKA did with Eksjo municipality reveals massive results.

 

In hockey season 2018-19 Eksjo's ice rink ran on more than 900 MWh energy a year.

After renovation:

2019-20 season 380 MWh

2020-21 season 260 MWh

Natural refrigerants and recovered energy is the new efficiency.

...Heading... something about typical problems or that they can be solved

Experience with more than 100 ice rink projects across the globe shows recurring deficiencies in ice rink management.

Extreme electricity and heating bills - a typical size ice rink uses about 1000 MWh of energy.

Many ice rinks are dealing with air moisture-caused problems in the summer, and another typical problem can be poor ice quality. These are just a few of the many challenges that ice rink facility managers are facing.

It often seems like these problems are perceived as a "normal part of the business" and something that cannot be avoided.

EKA has a true passion for finding feasible solutions to the technical challenges in ice rinks and increasing profits for entrepreneurs who offer ice rink facilities to promote a healthy lifestyle.

And not least we are glad that we are helping to save the planet.

Sustainable solutions fit for ice rinks

As technologies evolve it became clear that the best way to build a solid ice rink energy system is by using natural refrigerant CO2.

It is environmentally friendly, but just as important are the spectacular properties of CO2.

The most significant is heat recovery.

With heat recovery, you can put the otherwise waste heat into work. That energy can be used for air dehumidification, arena air heating, hot water, ice resurfacing water and other.

It's plain and simple - instead of burning gas or purchasing another energy medium for heating functions - reuse the energy from the internal processes.

This investment will save a lot of money.

We can see it now in the real world:

    -Since 2014 Europe has opened more than 50 doors to CO2 refrigerated ice rinks.

These numbers are increasing.

While the reasoning is both economical and environmental, there's also the fact that the world is moving away from synthetic refrigerants, preferencing natural solutions.

European Union is phasing out synthetic refrigerants that are harmful (HFCs). Most common synthetic refrigerants release 1500 - 4000 times stronger greenhouse gases than their natural counterparts. As an obvious consequence, it results in continuously growing prices for the old refrigerants.

Today natural refrigerants like Ammonia (NH3) and Carbon Dioxide (CO2) are up to 8 times more affordable than old synthetic refrigerants.

Dehumidification of air

These are only a few strong dehumidification error indicators

Air moisture related negative effects can be fixed by selecting the proper dehumidification technology.

Moisture control is a must in ice rinks. EKA’s expertise in dehumidification is based not only on a solid theoretical background but also on in-depth field analysis of numerous ice rinks.

There are potentially serious issues caused by poor design of moisture handling equipment in an ice rink, however, EKAs concept allows the following advantages:

 

  • No fog in the arena room

  • No condensation on glass/boards

  • No drippings from the ceiling

  • No mold growth

  • Significant energy savings

    • Heat Recovery implementation

  • Control Strategy optimization

Ice rink's bread and butter

Ice quality directly affects the speed of skating, hockey game dynamics, and user experience.

To achieve the "perfect ice" is a complicated matter that involves investigation of the whole chain reaction - rink floor, cooling system, arena climate, resurfacing procedures, and other aspects.

EKA has done research on this topic and possesses tools and methods to pinpoint the problems and find feasible solutions for the desired ice quality.

Heat source from the inside

It takes a lot for energy systems to secure the necessary functions in the ice rink.

The used-up energy often gets neglected - it gets "thrown out" in the atmosphere.
While it is definitely not good for ecological reasons, it is bad for ice rinks' economical purposes as well.

Ice rink needs energy not only for cooling. The ice rink needs dehumidification, hot water for showers, and arena air heating to keep spectators warm.

This is where the power of CO2 refrigerated ice rink comes into play,
CO2 allows applying heat recovery solutions. 

When such practices are available it seems unreasonable to not apply them to the ice rink.

An investment that benefits in the long-term.

It's never too late
