Abstract: In an air conditioning system which conditions air in one air-conditioning-target space with a plurality of air conditioners each including a compressor, the energy consumption efficiency as a whole is improved. The air conditioners (21 to 29) each include a service-side heat exchanger exchanging heat between air of a room which is the air-conditioning-target space and a refrigerant, a heat-source-side heat exchanger exchanging heat between air of a common space and the refrigerant, and a compressor (41 to 49) compressing the refrigerant circulating through the service-side heat exchanger and the heat-source-side heat exchanger. When an air conditioning capacity falls within a predetermined range for at least two of the plurality of air conditioners (21 to 29), part of the air conditioners whose compressors are in operation has its compressor stopped.

Abstract: 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.

Abstract: An air conditioning system includes air conditioners having a room temperature sensor to detect temperature of rooms, a mobile terminal carried by a user, and information mediation devices configured to cause exchange of information between the air conditioners and the mobile terminal using a public circuit. An air-conditioning management program installed in the mobile terminal is capable of causing an image that includes information related to a registered plurality of the air conditioners to be displayed on a display screen of the mobile terminal. When the rooms have been determined to be in a predetermined high-temperature state based on detection results of the room temperature sensor of the registered air conditioners, the information mediation devices provide a push-notification about the high-temperature information to the mobile terminal.

The common space-side heat exchangers of the air conditioners are disposed in the common space. The air conditioners are controlled based on temperature information items at plural positions in the common space.
