Energy Comparison
|
These figures represent the consumption of the ice rink chiller system only, including all circulation pumps, fans and electrical devices required for the total refrigeration system for the assumed load used in this calculation. These calculations were based upon actual manufacturers published performance data for the equipment referenced. These figures DO NOT include dehumidification, lighting, or any assorted general building use which can easily represent half of a complexes total electric billing nor are any provisions made for electrical demand charges typically billed to a complex. This information is offered for the evaluation of the specific chiller performances based upon the assumed conditions noted.
