An idle mitigation system for a bucket truck which includes an alternate source of power for the vehicle air conditioner which is coupled to the hydraulic system of the bucket truck which is hydraulic system is alternately powered by an electric motor which when run in reverse can charge batteries.

A compressor system for a vehicle comprising a vehicle internal combustion engine and a vehicle heating and cooling system. The compressor system comprising a compressor/motor generator defining a compressor motor/generator shaft, a compressor mechanically connected to the compressor motor/generator shaft; and a engine clutch mechanically connected to the compressor motor/generator shaft and to the vehicle internal combustion engine.

An electric compressor for a vehicle includes an inverter, a motor, and a first connector and a second connector electrically connecting an in-vehicle power supply and the motor with the first connector and the second connector being fitted to each other. The first connector includes a tubular receiving portion made of resin and a first conductive portion disposed inside the receiving portion. The second connector includes a tubular insertion portion made of resin and insertable into the receiving portion, and a second conductive portion disposed inside the insertion portion and connected to the first conductive portion. A rib is disposed between an inner surface of the receiving portion and an outer surface of the insertion portion. The rib is formed integrally with one of the inner surface and the outer surface, and is in contact with the other of the inner surface and the outer surface.

A working machine includes a machine body, a cabin on the machine body, an air conditioner body for air conditioning in the cabin, and a prime mover room to contain a prime mover on the machine body. The air conditioner body is disposed above the prime mover room.

A cooling system for a vehicle includes an inlet configured to receive a medium and a compression device including a shaft, a compressor connected to the shaft and having a compressor outlet, an electric motor connected to the shaft and configured to drive the compressor, and a turbine connected to the shaft and also configured to drive the compressor upon receipt of a compressed medium (to create an expanded medium). The turbine includes a turbine inlet and a turbine outlet. A load heat exchanger is connected to the turbine outlet and receives expanded medium therefrom. The load heat exchanger has a load heat exchanger outlet. At least one cooling heat exchanger has a heated flow inlet connected to the compressor outlet, a heated flow outlet connected to the turbine inlet, and a cooling flow inlet that receives a cooling medium from the load heat exchanger outlet.

An HVAC system includes a variable-speed compressor which compresses refrigerant flowing through the HVAC system, a blower which provides a flow of air through the HVAC system at a controllable flow rate, and a controller communicatively coupled to the variable-speed compressor and the blower. The controller receives a demand request, which includes a command to operate the HVAC system at a predefined setpoint temperature. In response to receiving the demand request, a setpoint temperature associated with the HVAC system can be adjusted to the predefined setpoint temperature. A speed of the variable-speed compressor is decreased to a low-speed setting. Based on the decreased speed of the variable-speed compressor, an air-flow rate can be determined to provide by the blower. The controllable flow rate of the flow of air provided by the blower can be adjusted based on the determined air-flow rate.

An HVAC system includes a compressor, condenser, and evaporator. A sensor measures a value associated with the refrigerant in the condenser or the evaporator, and a controller is communicatively coupled to the compressor and the sensor. The controller determines, based on an operational history the compressor, that pre-requisite criteria are satisfied for entering a sensor validation mode. After determining the pre-requisite criteria are satisfied, an initial sensor measurement value is determined. Following determining the initial sensor measurement value, the compressor is operated according to a sensor-validation mode. Following operating the compressor according to the sensor-validation mode for at least a minimum time, a current sensor measurement value is determined. The controller determines whether validation criteria are satisfied for the current sensor value. In response to determining that the validation criteria are satisfied, the controller determines that the sensor is validated.

A transport refrigeration unit (TRU) system is provided for use with a refrigerated cargo system. The TRU system includes a fuel cell configured to generate power for the TRU so that the TRU can refrigerate an interior compartment of the refrigerated cargo system, a cryo-compressed fuel tank to store a supply of cryo-compressed hydrogen, a heat exchanger and a conduit system configured to transport the cryo-compressed hydrogen from the cryo-compressed fuel tank, through the heat exchanger for promoting refrigeration of the interior compartment, and to the fuel cell.

A transport refrigeration system including a refrigeration unit for conditioning an area and a power system operably coupled to the refrigeration unit. The power system includes at least one fuel cell and a fuel source. At least a portion of one of the refrigeration unit and the power system is packaged into a replaceable module.
