PURPOSE:To realize comfortable condition that a head is kept cool and feet are kept warm, uniform air conditioning of a room and immediate effect of heating by a method wherein the downstream end of a high temperature air path is communicated to a lower face blow-off port formed in the lower wall part of the casing of a room instrument, on the other hand, the downstream end of a low temperature air path is communicated to a front blow-off formed in the front surface wall of the same casing. CONSTITUTION:When high temperature refrigerant carrier has flowed from the inlet section 2a of a refrigerant carrier at the indoor side heat exchanger 2, it is located to the refrigerant carrier overheating area, therefore, air passing through the refrigerant overheating area becomes high temperature by the heat exchange. The high temperature air is led to the high temperature air path 9a of the inside of the casing 10 by a fan 13, the warm of the high temperature is blown toward an indoor floor surface through a lower surface blow-off port 16. The refrigerant carrier at the refrigerant carrier saturating area and the refrigerant carrier supercooling area are kept in the low temperature condition comparatively, therefore, the heat energy applied the heat exchange for the air is small and the air becomes low temperature condition comparatively while it is led to the low temperature air path 9b of the inside of the casing 10 by the fan 13 and is blown from the front surface of the room instrument 1 as the low temperature warm air comparatively through the front surface blow- off port 15. |
