METHOD OF COLD SUPPLY TO AIR CONDITIONING SYSTEM OF INDOOR ICE RINK Russian patent published in 2012 - IPC A63C19/10 

FIELD: sports.

SUBSTANCE: method of cold supply to an air conditioning system of an indoor ice rink includes charging a cold accumulator by means of a refrigerating plant and further forwarding of a coolant via the cold accumulator into an air cooler of the air conditioning system. The cold accumulator mass is added into the cold accumulator storage in parts proportional to demand. For this purpose prior to operation of an ice rink an ice resurfacer is sent to its surface, with the help of which the first part of the cold accumulator is collected in the form of an ice crumb and ice chips from the rink surface, the collected ice is offloaded into the cold accumulator storage. Then in the mode of the rink operation periodically in accordance with the regulation and technology of ice preparation with ice resurfacers, collected ice is being added to the cold accumulator storage. The latter is irrigated with a coolant heated in an air cooler, and after the produced melted water is mixed into it, the mixture is cleaned from mechanical and biological inclusions, then disinfected. Prior to departures of ice resurfacers, the amount of ice in the cold accumulator storage is weighed, and the needed ice mass is calculated as required until the next ice loading into the accumulator storage, and the missing ice layer on the rink following the operation mode results is grown using an ice resurfacer after the operation mode.

EFFECT: reduced costs of power for air conditioning in an indoor ice rink.
