[Equest-users] Ice rink in sports arena

[Jim Fowler]

Rohini – Over the last few years, I have audited a number of ice arenas, although I have not modeled them in eQuest.  There are a lot of energy related issues with ice arenas.  It has been too many years and I’d have to dig up my reports and calcs for more specific information, but here’s a summary of the energy related issues that have to be considered: the direct (or indirect) ice refrigeration issues, cooling loads to keep the earth under the ice frozen (depending on what part of the country you’re in), sublimation of the ice to the space, the zamboni activities (also called re-surfacing) and subsequent ice melt of the shaved ice that the Zamboni picks up, ceiling emissivity, and finally, humidity control is a big one – lots of energy in de-humidifying the space to prevent ice fog.   I’ve attached a couple related articles on ice arenas and where the energy is used. 

 

There is a lot involved, can’t help you with specifics for the eQuest modeling part, other than to suggest, as Michael Hsueh did, creating schedules and adding the loads as separate refrigeration, heat and cooling loads with their own schedules, as appropriate.

 

Good luck.

Subject: [Equest-users] Ice rink in sports arena

 

Hi All,

I am modelling a sports arena which also has an ice rink (for 6 months of the year). On non-ice events, it is covered with the basketball court material. How do I consider the "coolth" that is getting conducted to the space on both ice and non-ice event times? 

Do you think I could put in a -ve number in the miscellanous loads category? How much should the load be? I have not been able to give it much thought other than writing this email. Since there is, as usual, a time constraint, I wanted to see what strategies others might have used.

As usual, appreciate any pointers and thanks in advance.
