VEHICLE CONDENSATION DETECTION DEVICE, VEHICLE AIR CONDITIONING APPARATUS, AND VEHICLE CONDENSATION DETECTION METHOD

In a control device 200 that serves as a vehicle condensation detection device, a vehicle-inside humidity specifier 210 specifies vehicle-inside humidity Hi that is humidity in a compartment of a vehicle. A vehicle-inside temperature specifier 220 specifies a vehicle-inside temperature Ti that is a temperature in the compartment. A vehicle-outside temperature specifier 230 specifies a vehicle-outside temperature To that is a temperature outside of the vehicle. A vehicle-inside wind velocity specifier 240 specifies a vehicle-inside wind velocity Vi that is a wind velocity of airflow formed in the compartment by an air conditioner that performs air conditioning of the compartment. A condensation determiner 260 makes, using values of the vehicle-inside humidity Hi, the vehicle-inside temperature Ti, the vehicle-outside temperature To, and the vehicle-inside wind velocity Vi, a determination on whether a state exists in which condensation can occur on an inside surface of the compartment. A determination result outputter 270 outputs a determination result that is a result of determination by the condensation determiner 260.
