From my experience a typical ice rink uses either ammonia r 22 or an hfc such as r 134a or r 404a.
Co2 air conditioning system.
Co2 can be used not only in air conditioning systems but also to operate heat pumps.
A hermetic co2 system figure 4 shows a simple co2 transcritical system block diagram.
The new co2 air conditioning systems.
Texa s product range includes diagnostic tools exhaust gas analysers and air conditioning system servicing and recharging stations.
