An air conditioning system suppresses energy consumption by efficient shared use of air in a common space that is not subjected to air conditioning in an indoor area, among a plurality of air conditioners for the purpose of heat exchange. A plurality of air conditioners each include: a usage-side heat exchanger configured to carry out heat exchange with air in an air-conditioning target space; a heat source-side heat exchanger configured to carry out heat transfer to and from the usage-side heat exchanger; and a heat source-side fan configured to feed air from a common space to the heat source-side heat exchanger and to blow the air into the common space. The heat source-side heat exchangers of the air conditioners are disposed in the common space. A first ventilation fan whose airflow volume is changeable is disposed near an exhaust port through which air is discharged from the common space toward an outdoor area. A controller changes the airflow volume of the ventilation fan, based on information on an air temperature of the common space.

Provided is an air conditioner including a housing, a suction port disposed in the housing, a first discharge port disposed in the housing to discharge a part of air sucked through the suction port, and a second discharge port disposed in the housing to discharge other part of air sucked through the suction port, a heat exchanger configured to perform heat-exchange on the part of air sucked through the suction port, a first blowing fan configured to suck the part of air, which is sucked through the suction port, to discharge the sucked air to the first discharge port, and an intermediate member configured to guide the part of air sucked through the suction port to the heat exchanger, and configured to separate other part of air s sucked through the suction port from the part of air sucked through the suction port.

A ventilation apparatus includes a housing having a front cover having an indoor air inlet and an air discharge opening, a rear cover having an outdoor air inlet and an indoor air outlet, and a side cover configured to connect edges of the front cover and the rear cover; a separation wall dividing the housing into a ventilation portion and an air conditioning portion; a total heat exchange element located in the ventilation portion; a supply-side mullion located adjacent to a first side of the side cover to define an outdoor air supply passage between the supply-side mullion and the first side of the side cover; a discharge-side mullion located adjacent to a second side of the side cover in the air conditioning portion to define an indoor air discharge passage; and an evaporator located between the supply-side mullion and the discharge-side mullion in the air conditioning portion.

A movable air conditioner includes an air conditioner main body, an air conditioning unit installed in the air conditioner main body and configured to generate a cold air or a warm air, a moving unit configured to move the air conditioner main body, a control unit configured to control the air conditioning unit and the moving unit, and a human body recognition unit configured to recognize a person existing in a specific space. The control unit is configured to control the moving unit so that the air conditioner main body is moved toward the person recognized by the human body recognition unit so as to supply the cold air or the warm air from the air conditioning unit to the person recognized by the human body recognition unit.
