Abstract
The article presents the results of developing a system for utilization of condensation heat from refrigerating units and air-conditioning systems of ice fields to decrease the dependency of engineering and technical systems of the objects on municipal systems of heating and hot water supply. The proposed solution provides saving of heat and electric energy consumed by both the refrigeration supply system and other systems of the object. When compressed gas overheating is used, an addition heat exchanger is added to the revegetating circuit allowing to utilize up to 20% of heat released by the unit. As the temperature of refrigerating medium may be above 100 °C in the end of compression process, the environment (water or air) is heated up to 80–90 °C. The technology has been developed for Small Ice Hockey Arena and Ice Hockey Training Rink in Sochi Olympic Park.
