Air-conditioning control system, air-conditioning management system, and in-vehicle air-conditioning system

An air-conditioning management system comprising:

• a first server that includes a first memory and a first processor coupled to the first memory, wherein
• the first memory stores a first program that, when executed by the first processor, causes the first processor to:
• obtain weather information including a weather forecast;
• predict, based on the weather information, an amount of change in a quantity of water droplets adhering to an evaporator of an air conditioner installed in a vehicle;
• and
• transmit the amount of change to an in-vehicle air-conditioning system of the vehicle, the in-vehicle air-conditioning system including an air conditioner electronic control circuit that includes a second memory and a second processor coupled to the second memory, wherein
• the second memory stores a second program that, when executed by the second processor, causes the second processor to
• control switching of an inside/outside air switching mechanism of the air conditioner based on the amount of change, the inside/outside air switching mechanism switching air delivered to an interior of the vehicle to one of inside air and outside air, the inside air being air in the interior of the vehicle, the outside air being air outside the vehicle.

An in-vehicle air-conditioning system comprising:

• an air conditioner electronic control circuit that is mounted on a vehicle and includes a second memory and a second processor coupled to the second memory, wherein
• the second memory stores a second program that, when executed by the second processor, causes the second processor to:
• estimate a current quantity of water droplets adhering to an evaporator of an air conditioner of the vehicle;
• receive change information transmitted from an air-conditioning management system, the air-conditioning management system including a first server that includes a first memory and a first processor coupled to the first memory, the first memory storing a first program that, when executed by the first processor, causes the first processor to predict an amount of change in a quantity of water droplets adhering to the evaporator based on weather information including a weather forecast, the change information including the amount of change;
• and
• control switching of an inside/outside air switching mechanism of the air conditioner based on an estimated quantity of water droplets and the amount of change included in the change information, the estimated quantity of water droplets representing the current quantity estimated, the inside/outside air switching mechanism switching air delivered to an interior of the vehicle to one of inside air and outside air, the inside air being air in the interior of the vehicle, the outside air being air outside the vehicle.
