A vehicle air-conditioning system has an intake door that switches between an inside air recirculation mode to take in air from an inside air introduction port and an outside air introduction mode to take in air from an outside air introduction port, a blower that blows the air introduced through any of the inside air introduction port and the outside air introduction port toward inside of a vehicle cabin, a heater that heats the air blown by the blower, and a controller that activates the heater when there is a request for heating the inside of the vehicle cabin, controls air conditioning such that an environment inside the vehicle cabin becomes a desired environment by set estimated time of departure.

Vehicle air-conditioning system and vehicle air-conditioning method

Preventing high-voltage components which constitute an electric instrument stored in a case from being exposed, dropping out, or scattering to an outside from the case even when the case of an air-conditioning unit has a significant impact. Therefore, a vehicle air-conditioning unit is provided with a protecting structure for preventing the electric instrument from scattering.

Vehicle air-conditioning unit and vehicle

A vehicle air conditioning system includes an electric powered refrigerant compressing device, an evaporator, an electric heater, an air temperature determining component, a cabin interior temperature controlling component, an upper limit electric power setting component, and an electric power distribution controller. The evaporator receives refrigerant from the compressing device. The heater is downstream of the evaporator in an air passageway. The determining component determines a first air temperature upstream of the evaporator and a second air temperature between the evaporator and the heater. The controlling component sets a vehicle interior discharge air temperature at a position downstream of the heater to a target temperature. The power setting component sets an upper limit for power supplied to the compressing device and the heater. The power distribution controller distributes the upper limit electric power to the compressing device and the heater based on a ratio of upstream and downstream temperature differences.
