Abstract

Two approaches were developed to study the influence of the multi-pass brine system on the ice surface temperature: the first one is analytical based on a simple thermal circuit employing 4 nodes with isothermal boundary condition at a specified depth within the soil underneath the slab and the second one is a numerical three-dimensional model which employs the control volume method to solve partial differential equations that describe the heat transfer through the ice sheet, the brine and the different layers under the concrete slab. The model is tested by comparing its predictions with measured values. Profiles of ice surface temperature are presented and analyzed for the two-pass and four-pass circuits. The results show that the two-pass circuit results in a more uniform ice temperature.
