Claims

[Scope of utility model registration request]

An air passage 7 through which air from the cooler unit 2 flows is formed in the unit case, and the heater core 8 is placed vertically so that a detour 9 that detours around the heater core 8 has approximately the same air blowing area as the air passage 7. A mix door is provided on the upstream side of the heater core 8 to branch the warm air that has passed through the heater core 8 and the cold air that has passed through the detour 9 at a predetermined ratio. A mixing chamber 11 for mixing the hot air and the cold air is formed on the side, and the mixed air is
A differential air outlet 12, a vent air outlet 13, and a foot air outlet 14 are provided to blow air into the vehicle interior, and the vent air outlet 13 is located downstream of the bypass path 9, and the foot air outlet 14 is located downstream of the heater core 8. In the air conditioner for an automobile having heater units arranged respectively, the mixture door 21 is set in a bilevel mode to guide the warm air to the vent outlet 13 and direct the cold air to the foot outlet 14. An air conditioner for an automobile comprising a guide door 22 that guides the air, and a temperature control door 23 that branches hot air and cold air at a predetermined ratio.
