When heating operation is performed by supplying fuel to the combustor 10 and operating the fan 9 and the air supply/exhaust fan, the combustion gas combusted in the combustor 10 first flows through the first heat exchanger 11 and is then It exchanges heat with the air flowing through the counter passage 7, heats the air, lowers the temperature to, for example, 150° C., and then flows into the second heat exchanger 15. However, the second
Since the heat exchanger 15 is provided at the upper position of the downward passage 6, the air flowing through this position is low-temperature air that has not yet been heated by the heater. As a result, the amount of heat held by the gas flowing into the second heat exchanger 15 is reduced to the second heat exchanger 1.
Therefore, it will be sufficiently recovered in the air circulating around 5. Therefore, the amount of heat discarded from the exhaust stack 14 to the outside air is reduced, and the thermal efficiency of heating can be improved.

The temperature of the exhaust gas flowing out from the second heat exchanger 15 is set to a temperature lower than the condensation temperature of water vapor, for example, 50°C.
By reducing the amount of heat to such a degree, the latent heat held by the water vapor can be recovered in the second heat exchanger 15, and the thermal efficiency of heating can be further improved.

低温の吸入空気にて良好に回収できるのである。 As described above, the present invention provides an indoor air inlet at the rear of the upper surface of the casing, and an air outlet at the upper front of the casing, and also provides a partition plate at the upper part of the intermediate position in the longitudinal direction of the casing, so that the air inlet is connected to the air inlet. A substantially U-shaped air passage is formed, consisting of a downward passage toward the bottom of the casing and along the rear surface of the casing, and an upward passage from the bottom toward the air outlet, and a fan is installed at the bottom of the casing. At the same time, a combustor is provided at the lower part of the upward passage, and a first heat exchanger communicating with the combustor is provided at the upper part of the combustor. While connecting the cylinders, a second heat exchanger was provided at the upper part of the downward passage, and the inlet side of the second heat exchanger was attached to the first heat exchanger, and the outlet side was attached to the rear surface of the casing. Since it is characterized by being connected to the exhaust stack, the low-temperature intake air that flows through the downward passage and before contacting the combustor and the first heat exchanger and the blow-out air are heated by the first heat exchanger. The combustion exhaust gas after
By exchanging heat with the heat exchanger, the amount of residual heat in the combustion exhaust gas after heat exchange with the blown air can be effectively recovered using the low-temperature intake air.

る。 In other words, the downward passage includes the combustor and the first
Since only the low-temperature intake air before being heated by the heat exchanger is passed through, a sufficiently large temperature difference between the intake air and the exhaust gas flowing in from the first heat exchanger side can be maintained. This will ensure good heat exchange in the heat exchanger, and
The temperature of the combustion exhaust gas can also be lowered to below the condensation temperature of water vapor, and the latent heat of the water vapor contained in the combustion gas can also be recovered favorably.

のである。 In particular, by forming a downward passage for intake air along the rear surface of the casing, it is possible to improve heat generation on the back side of the casing, reducing the high heat generated in the combustor to a safe temperature at the back of the casing. Therefore, the installation space between the back surface of the casing and the wall surface of the room can be reduced.
