2. Description of the Related Art Conventionally, an air conditioner installed in a power farm machine such as a tractor is installed on the ceiling of a cabin. Then, during cooling, the compressor provided in the engine room compresses the refrigerant, pressure-feeds it to the evaporator of the air conditioner on the ceiling, and blows the cool air into the cabin. On the other hand, during heating, the hot air from the heater core is pressure-fed to the air conditioner in the ceiling, and the blower blows warm air into the cabin.

Conventionally, since the air conditioner provided in the power farm is installed on the ceiling of the cabin as described above, a large space can be secured in the cabin, and the operator's overhead during cooling. Since the cool air is blown from the air, the cooling effect of the operator is good. However, since the piping from the compressor is long and the height difference between the piping is large, the horsepower loss of cooling and heating is large and the cost is increased. In addition, since hot air is blown from above the operator's head during heating, the operator often feels uncomfortable.
