Vehicle air-conditioning system with cold storage unit
A vehicle air-conditioning system calculates and indicates the remaining time of effective cooling by cold air discharge from its cold storage unit during a vehicular eco-run halt. In cold discharge cooling mode, a first cold discharge cooling remaining time tx1 is calculated from the remaining cold heat of a cold storage medium. A second cold discharge cooling remaining time tx2 is calculated from temperature changes of the cold storage unit. The second remaining time tx2 is set to zero when the cold storage unit temperature rises to a cooling upper target temperature. The first remaining time tx1 is selected in the cold discharge cooling mode as long as the temperature of the cold storage unit is below a temperature near the solidifying point of the cold storage medium. The second remaining time tx2 is selected when the cold storage unit temperature exceeds the temperature near the solidifying point.
