Air-Conditioning System for a Vehicle

An air-conditioning system for a vehicle, comprising:

• a refrigeration cycle circuit having a compressor that compresses a first cooling medium and a first heat exchanger that exchanges heat between the first refrigerant and external air;
• a cooling circuit that circulates a second cooling medium to a temperature controlling object to perform cooling/air-heating of the temperature controlling object;
• a second heat exchanger that exchanges heat between the first cooling medium and the second cooling medium;
• a temperature detection unit that detects a temperature of the object of temperature adjustment;
• a controller that controls the refrigeration cycle circuit and the cooling circuit based on a temperature detected by the temperature detection unit;
• a prediction unit that predicts a forward vehicle travel state based on a travel plan information that is input from a navigation device provided to the vehicle;
• and
• a target temperature change unit that changes an target temperature of the temperature controlling object or a target temperature of the second cooling medium based on a result of prediction by the prediction unit;
• wherein
• the controller controls the refrigeration cycle circuit and the cooling circuit based on a target temperature changed by the target temperature change unit to control cooling/air-heating of the temperature controlling object.
