PURPOSE:To prevent water from entering and rust from starting without need for providing a piping hole on a panel between a car room and an engine room by introducing refrigerent piping, which is connected to an evaporator, out of said car room through an outside-air introducing duct. CONSTITUTION:A high pressure pipe 27 and a low-pressure pipe 28, which are connected to an evaporator 6, are introduced within an outside-air introuduction duct 2, without being taken out of an air-conditioner case 25 into a car room. On the way, these pipes are introduced to an engine room outside the car room through outlet parts 29, 30 near, e.g., an outside-air intake 1, and connected to a compressor and a condenser. Thereby the drilling for piping on a panel separating the car room from the engine room can be eliminated, also without need for using a grommet, preventing water from entering and without causing rust to start. The layout in the car room can also be improved. |
