Abstract: A refrigeration cycle is a closed cycle constituted by a variable power compressor, a four-way valve, an indoor heat exchanger, an expansion valve and an outdoor heat exchanger. Air-conditioned air is supplied from the refrigeration cycle to a plurality of rooms to be subjected to air conditioning through a supply duct at a portion near a supply opening for supplying the air-conditioned air to a corresponding one of the rooms and controls a flow amount of the air-conditioned air supplied from the supply opening. Air is returned from each room to the refrigeration cycle through a return duct. The indoor heat exchanger of the refrigeration cycle has a temperature sensor for detecting the temperature of the indoor heat exchanger. A system controller controls a drive frequency of the variable power compressor of the refrigeration cycle in accordance with a difference between the temperature of the indoor heat exchanger detected by the temperature sensor and a preset temperature of the indoor heat exchanger.

Abstract: An air conditioner with a radiant temperature control comprises a refrigeration cycle for air-conditioning a room to be air conditioned at a desired temperature, a temperature setting section for generating set data for setting the desired temperature as a target value, a first temperature sensor section for detecting a room temperature of the room to be air-conditioned, a second temperature sensor section for detecting a radiant temperature of the room to be air-conditioned, a control section for receiving the set data from the temperature setting section and detection data from the first temperature sensor section and for generating an operation control signal to the refrigeration cycle in accordance with the difference therebetween, and a correcting section for receiving the set data from the temperature setting section and detection data from the second temperature sensor section and, when the difference therebetween deviates from a predetermined value, correcting the set data from the temperature setting
