The Use of Heat Generated from Refrigeration System of Indoor Ice Hockey Arena

Popis výsledku v původním jazyce

Maintaining the ice arena, specially keeping high quality of the ice sheet, is energy and therefore economically intensive. The others energy consumers are hot water for ice sheet treading machine preparation, hot domestic water preparation, space heating, air conditioning systems and lighting. To apply the most efficient energy saving solution is necessary to analyze the highest energy consumer. Definitely, the highest energy consumer is cooling of an ice sheet what impact can be reduced by introducing a system reusing a refrigeration heat which rises as a side product. Heat exchangers can be added into the cooling cycle to utilize refrigeration heat. The refrigeration heat rises at two temperature levels as a superheat and latent condensing heat. Adding a heat exchanger to utilize the superheat is usual in many ice arenas in the Czech Republic. Otherwise utilization of latent condensing heat is not that common because of presumed high investment costs. This phenomenon is studied in the paper. The natural gas and water consumption for technical and hygienic purposes had been measured in the ice arena. The amount of superheat and latent condensing heat available from the cooling units was calculated according to the estimated running hours and manufacturer’s data. Utilization analysis of low temperature latent condensing heat together with water to water heat pump was made. Utilization of the low temperature heat will be assessed according to the reached primary energy sources savings.
