Abstract
A vehicle air conditioning device comprises first and second outside air ventilation flues that are formed so that outside air flows through opposing ends of an evaporator. An inside air ventilation flue is formed so that inside air flows through a central site in the evaporator such that, at any degree of opening of a first damper, outside air from each of the outside air ventilation flues and inside air from the inside air ventilation flue can flow to an outlet-side ventilation flue or a heater-side ventilation flue at a flow rate that corresponds to the degree of opening of the first damper. Accordingly, even in a configuration in which outside air and inside air flow to the evaporator, it is not necessary to provide the first damper that opens/closes a downstream side of the evaporator for each of the outside air and inside air flow sections.
