Calculation of the thermal loads of an ice rink using a zonal model and building energy simulation software

A municipalice rink in Montreal was modeled and its transient thermal behavior was evaluated for a typical year using a zonal model coupled to building energy simulation software. The calculated temperatures of the air above the ice and that of the southern wall are close to the corresponding measured values. The results show the seasonal effects as well as those of the occupation and the resurfacing on the temperature of the ice, the temperature of the air and the average and maximum monthly load transmitted toward the brine. They also show the effect of the airflow in the interior of the building on the temperatures and loads. Parametric studies were carried out to determine the effects of the ventilation air temperature and the average brine temperature on the refrigeration load, the ice temperature, and the air temperature above the stands.
