  • Patent number: 11203249
    Abstract: Certain disclosed embodiments pertain to controlling temperature in a passenger compartment of a vehicle. For example, a temperature control system (TCS) can include an air channel configured to deliver airflow to the passenger compartment of the vehicle. The TCS can include a one thermal energy source and a heat transfer device connected to the air channel. A first fluid circuit can circulate coolant to the thermal energy source and a thermoelectric device (TED). A second fluid circuit can circulate coolant to the TED and the heat transfer device. A bypass circuit can connect the thermal energy source to the heat transfer device. An actuator can cause coolant to circulate selectively in either the bypass circuit or the first fluid circuit and the second fluid circuit. A control device can operate the actuator when it is determined that the thermal energy source is ready to provide heat to the airflow.

  • Patent number: 10421338
    Abstract: There is disclosed a vehicle air-conditioning device in which a refrigerant subcool degree in a radiator is appropriately controlled, so that comfortable and efficient vehicle interior air conditioning is achievable. The vehicle air-conditioning device executes a heating mode in which a controller lets a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, decompresses the refrigerant by which heat has been radiated by an outdoor expansion valve 6, and then lets the refrigerant absorb heat in an outdoor heat exchanger 7. In the heating mode, the vehicle air-conditioning device controls a refrigerant subcool degree SC of the radiator 4 by the outdoor expansion valve 6. On a basis of a radiator inlet air temperature THin that is a temperature of the air flowing into the radiator 4, the controller corrects a target subcool degree TGSC that is a target value of the refrigerant subcool degree SC in the radiator 4 in a lowering direction, as the radiator inlet air temperature THin rises.

    Abstract: An apparatus is provided for removing gas from a vehicle storage unit. The apparatus includes at least one memory and a processor(s) detecting air being drawn, via an exhaust unit, from the front of a vehicle storage space to a rear of the vehicle storage space and through a ventilation unit forcing the air including emitted gas(es) to exit a top of the ventilation unit. The air is initially directed, from a supply unit in an upper part of the ventilation unit, into the rear of the vehicle storage space to the front of the vehicle storage space. The items emitted the gas. The computer program code may further cause the apparatus to measure the gas as the air passes through the ventilation unit to determine whether the measured gas equals or is below a predetermined threshold. Corresponding computer program products and methods are also provided.
