EVALUATION OF THE OVAL RINK FLOOR �.o�t _ 4��5,04{i .�?��.3�+�0 ��'�. �.9 S 5,.�{I+� ��I,00� � !4'3r1{}��i�J I �x'-',[i(�+� � _ _ ��S9��U�y We performed a brief evaluation of the rink floor including the apparent movenaent of the concrete rink slab. W e recommend ti�e rink floar be surveyed so the existing floar elevations can be compared to the elevations fi'am the original constmction. This will assist in detennining if the rink slab is moving or if the perimeter concrete and asphalt is settling. There does not appear to be any major cracking in the concrete slab that would indicate a significant problem or potential damage to the rink piping. Therefore the floor appears to be in good condition. Some movement in the floor is normal given its type of construction. lf the rink slab has moved upwards, there is little, if anything, that can be done cost effectively to correct this problem. lt is recommended that the elevation of the rink floar be monitored as discussed above and that the perimeter asphalt or concrete that has settled be replace to improve drainage. STEP 6- EVALUATE FEASIBILITY OF CONNECTING THE RSVC ARENA TO TFlF JOHN ROSE OVAL' S REFRIGERATION SYSTEM General '1'he purpose of this evaluation is to detennine if the existing refrigeration system serving the oval can also serve the RSVC arena. The existing 163 ton direct refrigeration system in the RSVC _ arena will have to be replaced soon as discussed in this report. Capacity and Energy Requirements The indirect refrigeration system serving the oval has a total refrigerafion capacity of 800 ton. The system operates between tf��e inonths of November and March each year. The system does operate at 100% capacity several times during fall and spring operations. During this same time the RSVC arena will require a refrigeration capacity of approximately 60 to 80 tons or 7.5% to 10% of the oval's total refrigeration capacity. This is a fairly substantial amount of refrigeration capacity that would be lost especially during the times of the year when the heat loads on the outdoor ice sheet are the greatest. During�'uc summer months, when the oval is shutdown, the RSVC arena will require a refrigeration capacity of approximately 70 to 100 tons ar approximately 8.8% to 12.5% of the oval's refrigeration capacity. Even if the large chiller vessel can efficiency transfer heat at a substantially lower flow rate (1000 gpm} than the original design (5500 gpm), which Vilter Manufacturing is currently verifying, one of the oval's large compressors would have to be operate to serve the refrigeration system. Each compressor is 450 harsepower providing ��
