An air conditioning system, combining an air conditioner and a radiant heat exchanger, is provided with which convection of indoor air is promoted by the radiant heat exchanger to suppress air blowing by a fan of the air conditioner and thereby reduce a draft sensation. An air conditioning system A1 includes an air conditioner, having an outdoor machine and an indoor machine incorporated in a refrigeration cycle, and a radiant heat exchanger, having a heating element, including and arranged from piping through which a refrigerant passes, and having the respective piping making up the heating element connected to a piping connecting the outdoor machine and the indoor machine and passing the refrigerant, the radiant heat exchanger has rectifier plates that are vertically disposed with gaps, through which air passes, provided with respect to the heating element at the front surface side and rear surface side of the heating element, and each rectifier plate has a plurality of radiant heat passing pores. |

1. An air conditioning system comprising:
an air conditioner having a refrigerant circuit, in which a compressor, an expansion valve, a flow path switching valve, an indoor side heat exchanger, and an outdoor side heat exchanger are connected by piping to circulate a refrigerant to perform a refrigeration cycle, and supplying air, which has undergone heat exchange with the refrigerant at the indoor side heat exchanger, to an indoor space by a fan; a radiant heat exchanger having a heating element incorporated in the refrigerant circuit of the air conditioner; rectifying plates sandwiching the heating element of the radiant heat exchanger in between and each covering a surface of the heating element across a gap provided with respect to the surface, having the inner surface arranged as a reflecting surface that reflects the radiant heat radiated from the heating element, having a radiant heat passing portion penetrating through the inner and outer surfaces and allowing passage of radiant heat and air, and promoting air convection by a chimney effect, and an operation mode switching means by which switching to a single operation mode among the respective operation modes of a first operation mode of putting the air conditioner and the radiant heat exchanger in operation, a second operation mode of putting only the air conditioner in operation, and a third operation mode of putting only the radiant heat exchanger in operation is performed automatically or manually; and wherein the operation mode switching means is one selected from the group consisting of: the operation mode switching means that includes a
