Heat Recovery of the Refrigeration System in the Ice Arena
Original language description
Maintaining good quality ice over the surface of an ice arena and keeping it as uniform as possible is a huge energy consumer. The ice arena also consists of many HVAC systems with differencing demands and specific technologies. To save energy is necessary wherever it is possible and the heat recovery from the refrigeration system offers interesting possibilities. In the steam compressor cooling cycle, the waste heat rises in several temperature levels. According to the waste heat temperature, the options of its utilization in an ice arena are discussed and evaluated in the paper. Also, measured energy consumptions and experience with the operation of the ice hockey arena will be presented in the paper. This solution has not often been used in the Czech Republic so far. The highest used amount of energy consumed by all the HVAC systems is the one used for cooling the ice sheet. The refrigeration heat utilization leads to energy savings in the hot water preparation system, in melting the snow pit and also in subfloor heating. If condensing heat is reused, the energy savings can also be extended in space heating, preheating ventilation air and in a dehumidification system.
