Is there a major difference in using proplyene or ethelyene glycol as opposed to a brine solution in an ice rink( we are using an air cooled chiller 220 tons, 2 screw compressors with ***** as the refrigerant).
We will be closing this summer for maintenance and was curious as to the heat removing qualities of each liquid. We currently are using proplyene and considering one of the others as a cost saving idea. We were told (not by any experts in the field) that brine has a much better heat transfer quality than glycol. Any comments. Thanks
