Summary

Reducing the consumption of energy resources in sports facilities is the goal of a/l opera tors. Among the main energy consumers in a winter stadium belong ice-rink cooling, heating of water for the ice resurfacer, hot water preparation, heating, HVAC systems and ice-rink ilIumination. The most demanding on the power consumption is the ice rink cooling. The heat generated as a byproduct of cooling can be subsequently used and thus the operation costs can be reduced. Integration of a heat exchanger to utilize the superheated refrigerant vapors of the cooling cycle is already an extended application, whereas heat recovery is not. Consumption of natural gas in the boiler room, water consumption for ice resurfacer and hot water consumption in the locker room are analyzed for a case study of one hockey season at the winter stadium in the Czech Republic. The heat of superheated refrigerant vapors is utilized in the facility. Potential benefit of low-potential condensation heat recovery in combination with a heat pump is assessed computationally. Utilization of condensation heat is evaluated in terms of the prospective savings and investment costs.
