Air Conditioning System

Abstract

An air conditioning system includes a heat source unit, an air supply device, and a heating medium circuit. The heat source unit heats a heating medium that is used for heating the room. The air supply device supplies outdoor air to the room as ventilation air. The heating medium circuit includes at least one room heating device that releases the heat of the heating medium, and an outdoor air heating device that heats the ventilation air with the heat of the heating medium. The heating medium circuit circulates the heating medium between among the room heating device, the outdoor air heating device, and the heating medium—refrigerant heat exchanger.
