SUPPLY AND RECIRCULATION UNIT WITH AIR TEMPERATURE CHANGE FUNCTION AND METHOD FOR CHANGING AIR TEMPERATURE Russian patent published in 2023 - IPC F24F7/00 F24F1/03 

FIELD: room air supply and recirculation units.

SUBSTANCE: invention is related to room units that provide fresh air supply to the room, as well as changing the temperature of both supply and recirculation air. The supply and recirculation unit includes an air duct for supply air, a refrigeration circuit with refrigerant, an indoor unit and an outdoor unit. The housing has at least one opening for supply air intake, equipped with a heating element, at least one opening for recirculating air intake and at least one opening for air extraction. The hole for intake of fresh air communicates with the air channel. The housing of the indoor unit contains a heat exchanger connected to the refrigeration circuit of the unit, a fan and at least one filter. The housing of the external unit houses a compressor and a heat exchanger connected to the refrigeration circuit.

EFFECT: highly efficient cooling and heating of both recirculated and supply air is achieved, while maintaining high performance and reducing energy consumption when heating or cooling air.
