A system for controlling air-conditioning in a vehicle includes an input, a sensor, a first offset module, and an evaporator temperature control module. The input receives an input temperature. The first sensor measures a first dewpoint temperature of air adjacent to a windshield of the vehicle. The first offset module generates a second dewpoint temperature based on the input temperature and generates a first offset based on the first and second dewpoint temperatures. The evaporator temperature control module generates a target evaporator temperature based on the first offset.

Efficient AC operation using dew-point temperature

A system for controlling air-conditioning of a vehicle includes an input, an offset generator module, and an evaporator temperature control module. The input receives an input temperature. The offset generator module receives a psychrometric parameter of air inside the vehicle and generates offsets based on the input temperature and the psychrometric parameter. The evaporator temperature control module generates a target evaporator temperature based on the offsets.

In a cooling system, particularly a cooling system for motor vehicles, including a cooling circuit and a refrigerating circuit which are coupled to one another via a refrigerant/coolant heat exchanger and a third medium/coolant heat exchanger arranged in the cooling circuit, a heat source to be cooled is arranged in the cooling circuit and means are provided for controlling the quantity of coolant flowing through the refrigerant/coolant heat exchanger.
