PROBLEM TO BE SOLVED: To provide an in-ceiling heat recovering machine with which energy- saving heating operation of an air conditioner is made practicable. SOLUTION: The machine body 21 is formed with a ceiling air inlet 22, a ceiling air outlet 23, an outside air inlet 24, and an outside air outlet 25 are formed in a machine body 21. A heat recovery air duct E, communicating with the ceiling air inlet 22 and the ceiling air outlet 23 and an outside air treating air duct F communicating with the outside air inlet 24 and the outside air outlet 25. A sensible heat exchanger 26, for heat-exchanging the outside air through the outside air inlet 24 and ceiling air through the ceiling air inlet 22, is situated astriding the heat recovery air duct E and the outside air treating air duct F. Heat recovery outside air through the outside air outlet 25 is taken into the air conditioner. |
