1. Load calculation of ice rink
The main difference between ice rinks and refrigerators or air conditioners is that the refrigerant doesn’t cool the ice directly. Instead, the refrigerant cools glycol, which is an anti-freeze agent that is pumped through pipes underneath the ice.The load of the ice rink mainly depends on the purpose and structure of the ice rink, the size of the ice rink, the latitude and topography of the ice rink, and the length of the season of use. From the analysis of the cooling load per unit area of the ice rinks that have been built in northern country, below is one of H.Stars project example:
The indoor ice skating rink is about 163~233w/m2.
The outdoor ice skating rink is about 488~512w/m2.
The load of ice rink will decide the capacity of ice skating rink chiller
1.Skating surface
2.Chilled concrete slab
3.Insulation
4.Heated concrete
5.Sand and gravel base
6.Ground water drain
