AIR CONDITIONING SYSTEM FOR INDOOR RINKS WITH ARTIFICIAL ICE Russian patent published in 2024 - IPC F24F7/08 F24F11/72 

FIELD: air conditioning systems.

SUBSTANCE: invention relates to air conditioning systems and can be used to provide specified parameters of microclimate in zone of ice field of indoor skating rinks. Air conditioning system of an indoor ice rink contains an additional exhaust fan, air valves with electric drives, a mixing chamber, pressure and temperature sensors, supply-and-exhaust air ducts and air intake devices located in the upper and serviced zones of the ice rink, which allows bleeding air with different parameters for recirculation, which is then supplied to separate mixing chambers. Air from two zones is supplied for treatment due to two controlled fans installed in separate sections of central air conditioner, which prevents premature mixing of recirculation flows. Due to regulation of ratio of flow rates of recirculating air with different parameters, smooth regulation of parameters of air supplied to zone of ice field is provided.

EFFECT: providing a sequence of air treatment taking into account the location of the equipment and controlling its operation in the system, aimed at reducing the consumption of heat and cold when treating the air before its supply to the serviced area, and eliminating the need for additional humidification in the nozzle chamber, as well as to reduce the probability of freezing of the heat exchange surface of the air cooler.
