Question

An ice rink 35 m long by 20 m wide is located in a building 60 m long by 50 m wide by 15 m high. The ice is maintained at -8°C, the walls of the building are at a temperature of 16°C, and the air in the building is at a temperature of 10°C. The emissivity of the walls is 0.8, and the emissivity of the ice is 0.97. The heat transfer coefficient at the surface of the ice is 50 W/m^2°C. Determine the rate at which the refrigeration system must remove heat from the concrete pad beneath the ice in order to maintain these conditions.

Step 1

The heat transfer through the walls can be calculated using the formula: Q = U * A * (T1 - T2) Where: Q is the heat transfer rate U is the overall heat transfer coefficient A is the surface area of the walls T1 is the temperature inside the building T2 is the Show more…
