FIELD: cooling or freezing equipment.
SUBSTANCE: invention relates to refrigerating industry. Method of energy saving during production of artificial cold for ice arenas includes implementation of cold supply of arenas with brine cooling system. In winter period cold coolant is supplied by pumps to the closed arena, where it is heated, taking heat from the cooling plate. From the closed arena the coolant is supplied to the open arena, where it is cooled, giving an equivalent amount of heat through the ice layer to the environment.
EFFECT: reduced power consumption of refrigerating unit in winter period of time.
