[Equest-users] Ice rink in sports arena

[Michael Hsueh]

Rohini,

I'd think of it less as the "coolth" being added to the space from the ice
and more as the electrical energy required to run compressor to maintain
the ice. I'm assuming that ice rinks don't heat the air since people are
perfectly comfortable with the idea of a rink being cold with so much ice
present. In the summer, this load for keeping ice frozen goes away.

In terms of practical ways to do it, I'd schedule some sort of
refrigeration load equivalent to what's needed to maintain the ice in the
winter -- have a thermostat setpoint that's basically equivalent to setting
that space to unconditioned. In the summer your schedule will turn off the
refrigeration load and then set that space back to conditioned.

That's just off the top of my head. Curious about thoughts others on the
forum would have about this.

Best,

-Michael
