A heating and ventilation system for a passenger compartment of a vehicle. The system having a heater core supplied with engine cooling fluid via a variable flow pump for heating an air flow supplied to the passenger compartment. The system additionally having a controller for controlling the pump to increase engine cooling fluid mass flow-rate in response to a detected temperature decrease of the engine cooling fluid when the engine is off.

Variable electric auxiliary heater circuit pump

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.
