A vehicle has a drive motor and a refrigerant circuit. The refrigerant circuit includes, when viewed in the direction of flow of the refrigerant, a compressor, a gas cooler or condenser, an expansion device and an evaporator. The refrigerant circuit has a first shut-off element which is arranged outside of an area arranged between the drive motor and the evaporator.

A vehicle air-conditioning apparatus includes a refrigerant circuit including a heat exchanger, a fan which sends air to the heat exchanger, and a controller which controls the refrigerant circuit and the fan. The vehicle air-conditioning apparatus is mounted on a vehicle. The controller acquires a physical quantity correlated with a clogging amount of the heat exchanger when a position or a speed of the vehicle satisfies a predetermined condition, and determine whether or not clogging occurs in the heat exchanger based on the physical quantity.

A vehicle air-conditioning apparatus includes a refrigeration cycle that performs air-conditioning in a vehicle interior of a vehicle; a controller that includes a plurality of operation modes with different continuous operation times for a compressor, and that selects one operation mode from among the plurality of operation modes according to an air-conditioning load in the vehicle interior and executes the one operation mode, during travel operation of the vehicle; a storage unit; and a fault diagnosis unit. The fault diagnosis unit performs, during travel operation of the vehicle, fault diagnosis for the refrigeration cycle, after the high-load operation mode from among the plurality of operation modes, in which the continuous operation time is equal to or longer than a time that is set in advance is selected and executed by the controller at the timing stored in advance in the storage unit and while the refrigeration cycle is stable.

A method for operating an electric motor-driven refrigerant compressor of a motor vehicle is provided. A first temperature of a power semiconductor is measured, and a second temperature of the power semiconductor is determined using a theoretical model of the motor-driven refrigerant compressor. A difference between the first temperature and second temperature is determined. A fault is detected if the difference is greater than a first threshold. The invention further relates to a motor-driven refrigerant compressor of a motor vehicle, to the use of a motor-driven refrigerant compressor, and to a motor vehicle comprising a refrigerant circuit.

A heater unit includes a heater case and a high-voltage component disposed on a mount surface of the heater case. A protector is disposed in front of the heater unit. The protector includes a protection cover and a protection member disposed laterally of the high-voltage component. The protection member includes a side surface (support wall) disposed along a forward-rearward direction; that is, an assumed collision direction. The leading edge of the side surface protrudes further than the high-voltage component. The length of the side surface in the forward-rearward direction is longer than the length from a position on the heater case with which the side surface comes into contact in a collision to a front surface of the high-voltage component.

Technologies described herein are directed to isolating or insulating at least portions of an evaporator coil within a climate control unit (CCU) of a TCCS so as to reduce or even eliminate adverse effects caused by a leaked working fluid. Such adverse effects may include a threat of ignition, asphyxiation of occupants, damage to cargo, and other harmful effects caused by emission of a noxious gas. A leak isolation structure is provided to isolate evaporator tubes of an evaporator coil from at least one of a plurality of turns of the evaporator coil.

A method for notifying and mitigating a suboptimal event occurring in a transport climate control system that provides climate control to a climate controlled space of a transport unit is provided. The method includes monitoring an amount of power available for powering the transport climate control system, monitoring a power demand from the transport climate control system, and accessing operational data of the transport climate control system and the transport unit. The method also includes a controller determining whether a suboptimal event is detected based on one or more of the monitored amount of power available, the monitored power demand and the accessed operational data. Also, the method includes the controller generating a notification when a suboptimal event is detected, and the controller instructing the generated notification to be displayed on a display.
