A vehicle air conditioner installed in a vehicle includes: a condenser that causes heat exchange between a coolant and outside air; at least one spray nozzle that sprays water to a portion near the condenser; and a water tank that is in communication with the spray nozzle through an output hose, and stores the water to be sprayed. The at least one spray nozzle is disposed at a higher level than the water tank.

A method for preserving autonomous operation of a transport climate control system is provided. The method includes the controller determining whether a regulatory compliance at a current location is restricting and/or preventing the use of a prime mover for powering the transport climate control system while a transport unit is in transit. When the controller determines that use of the prime mover is not being restricted or prevented because of a regulatory compliance, the method includes operating the transport climate control system and the transport power system in an energy harvesting operation mode for storing excess power generated by the prime mover into the auxiliary energy storage. When the controller determines that use of the prime mover is being restricted or prevented because of a regulatory compliance, the method includes the controller instructing the auxiliary energy storage to provide power to the transport climate control system.

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 voltage conversion system includes an energy storage device; a power conversion unit connected to the energy storage device, the power conversion unit comprising: an inductor, the inductor comprising a number of coils that are non-coupled or weakly coupled, with a coupling coefficient less than 0.05; a multi-phase boost stage coupled to the inductor, wherein the multiphase boost stage comprises a number of phases that equals the number of coils; an inverter coupled to the multiphase boost stage; and a load coupled to the power conversion unit.

There is disclosed a vehicle air-conditioning device in which a heating qualification by gas injection can sufficiently be obtained. The vehicle air-conditioning device comprises a compressor 2 which compresses a refrigerant, an air flow passage 3 through which air to be supplied into a vehicle interior flows, a radiator 4 disposed in the air flow passage to let the refrigerant radiate heat, a heat absorber 9 disposed in the air flow passage to let the refrigerant absorb heat, an outdoor heat exchanger 7 disposed outside the vehicle interior to let the refrigerant radiate or absorb heat, and a controller. The controller executes a heating mode in which the refrigerant discharged from the compressor 2 radiates heat in the radiator 4 and the refrigerant by which heat has been radiated is decompressed and then absorbs heat in the outdoor heat exchanger 7. The vehicle air-conditioning device comprises an injection circuit 40 which distributes a part of the refrigerant flowing out from the radiator 4 to return the refrigerant to the middle of compression by the compressor 2, and the injection circuit 40 has an expansion valve 30, and a discharge side heat exchanger 35 which performs heat exchange between the refrigerant decompressed by the expansion valve 30 and the refrigerant discharged from the compressor 2 before flowing into the radiator 4.

An airflow direction plate elongated in a direction perpendicular to a direction of an air flow from an indoor fan is disposed between the indoor fan and an air supply duct opening. The airflow direction plate has air vents arranged in a longitudinal direction, inclined plates each disposed to a corresponding one of the air vents and having different angles of inclination corresponding to positions of the air vents, and an acoustic material disposed on a surface facing the indoor fan. An indoor unit has a first air passageway allowing the air from the indoor fan to flow in the longitudinal direction of the airflow direction plate for a detour to the air supply duct opening and a second air passageway allowing the air from the indoor fan to flow into the air vents along the inclined plates.

Technologies are described herein for cooling systems. In some aspects, a cooling system is configured to enter into a storage configuration or a winterization configuration. In the winterization configuration, refrigerant used in the cooling system is stored in an adsorbent in an adsorbent chamber.

The disclosure herein relates to a vehicle compressor control apparatus and control method, and more particularly to a vehicle compressor control apparatus for controlling compressor operating rate to allow braking according to brake negative pressure, while maintaining a minimum level of operation of the compressor. By preventing compressor deactivation during braking, the control apparatus assists in preventing moisture build-up of moisture on a windshield that decreases visibility for a driver and increases safety concerns. The apparatus includes: a compressor that reduces a temperature by compressing an air conditioner coolant; a data sensor that detects status data; and a controller that determines whether a brake negative pressure margin rate meets a first reference value when the status data satisfy a predetermined condition, and sets a compressor operating accordingly when the brake negative pressure margin rate meets a first reference value.

A vehicle includes a refrigerant system having a chiller and a coolant system having a chiller loop and a radiator loop. The chiller loop is arranged to circulate coolant through the chiller, and the radiator loop is arranged to circulate coolant through a battery, a radiator, and a bypass valve connected to a bypass conduit. A controller is configured to, in response to an ambient-air temperature exceeding a battery-coolant temperature, actuate the valve to circulate coolant to the bypass conduit to skip the radiator.
