PURPOSE:To raise comfort feelings as well as save the consumption of energy by improving the temperature distribution in an air conditioning room and the air conditional operation by a method in which a radiative-heating body is set by turning it toward the inside of room to paired inside-air room heat exchangers for a room unit, and in a refrigerating cycle, a radiative heating body is set even on the front flow side of the inside-room heat exchanger. CONSTITUTION:During the cooling operation, a refrigerant passes through a compressor 12 outside-room heat exchanger 14 expansion valve 15 radiative heating bodies 2a and 2b inside-room heat exchanger 1 check valve 17 compressor 12. The low- pressure and low-temperature refrigerant coming out of the valve 15 cools the air in room on the heating bodies 2a and 2b, and air blown in through a floor panel 8 by the air blower 10 is passed through the inside-room heat exchanger 1 for cooling operation. During the heating operation, the refrigerant is circulated in the order of the compressor 12 the radiative heating bodies 3a and 3b the heat exchanger 1 the check valve 16 the valve 15 the outside-room heat exchanger 14 the compressor 12. The high-temperature refrigerant discharged heats up the air of room on the heating bodies 3a and 3b and then heats up the air of room to be circulated in the heat exchanger 1 after being sucked into the upper opening 6 by the air blower 10 to form hot air. By the hot air, heating operation is made through the floor panel 8. |
