Auxiliary air-conditioning system for over-the-road trucks
The invention relates to a system that is added to a standard vehicle installed air-conditioning system that allows the standard vehicle installed air-conditioning system to cool and condition the air inside the vehicle without operating the engine of the vehicle. This allows the vehicle to be air-conditioned without polluting the air via continuous operation of the vehicle's (usually) diesel engine. Also, a thermal heating tank is included to warm the electrical components of the system and to ensure improved morning starting of the vehicle's engine.
Method and system for dynamic power allocation in a transport refrigeration system
A method and system for dynamic power allocation in a transport refrigeration system (TRS) is provided. The method includes a TRS power source operating in an operational state. The method also includes monitoring an amount of current being drawn from one or more generator powered components of the TRS. Also, the method includes calculating, via a TRS controller of the TRS, a maximum available horsepower amount based on the amount of current being drawn from the one or more generator powered components. Further, the method includes controlling, via the TRS controller, an amount of horsepower directed to a compressor of the TRS based on the maximum available horsepower amount.
PRESSURE REGULATOR WARM UP SYSTEM FOR A TRANSPORT REFRIGERATION UNIT
A fluid circuit for a trucking vehicle having a transport refrigeration unit is provided. The fluid circuit includes a first regulator assembly defining a first fuel inlet that is arranged to receive fuel from a first fuel tank and a first fuel outlet that is arranged to provide fuel to a first engine. The first regulator assembly having a first heat exchanger assembly defining a first coolant inlet that is arranged to receive coolant from a cooling system associated with the first engine and a first coolant outlet that is arranged to provide coolant to the cooling system.
HYBRID-POWER TRANSPORT REFRIGERATION SYSTEMS
Hybrid-power transport refrigeration system (200) having a fixed-speed generator (202), a refrigeration compressor (204), a power bus (208) electrically connecting the fixed-speed generator (202) to the refrigeration compressor (204), an energy storage device (220) electrically connected to the power bus (208) and arranged to receive power from the fixed-speed generator (202) in an engine-operation mode and to supply power to the refrigeration compressor (204) in a battery-operation mode, and a DC/AC variable frequency drive electrically connected between the energy storage device (220) and the refrigeration compressor (204) to convert a DC power supply from the energy storage device (220) to a variable frequency power to drive the refrigeration compressor (204) when in the battery-operation mode.
TRANSPORT REFRIGERATION SYSTEM AND METHOD OF REGENERATING A DIESEL PARTICULATE FILTER
A method for performing a regeneration cycle for regenerating a diesel particulate filter of a transport refrigeration system. The method includes increasing an air intake throttling level of an engine intake air flow by reducing an air control valve area. The method also includes supplementing the temperature increase of the air intake throttling by energizing an engine preheater.
System and method of controlling passage of refrigerant through eutectic plates and an evaporator of a refrigeration system for a container of a vehicle
A system including mode, engine, and battery modules, where the mode module determines whether to operate in an engine mode or a battery mode based on parameters. The engine module, while operating in the engine mode, runs a compressor at a first speed based on a temperature within a temperature controlled container of a vehicle and permits passage of refrigerant through eutectic plates independent of the temperature. A battery, while in the engine mode, is charged based on power received from an electrical source. The battery module, while operating in the battery mode and based on the temperature, runs the compressor at a second speed and prevents passage of the refrigerant through the eutectic plates. While in the battery mode, the battery is not being charged based on power from a shore power source and the electrical source from which power is received during the engine mode.
FUEL CELL ARCHITECTURE FOR TRANSPORT REFRIGERATION UNIT
A transport refrigeration system includes a tractor, a container connected to the tractor, a refrigeration unit for conditioning a compartment of the container, a first power system associated with the cargo container and operably coupled to the refrigeration unit, and a second power system associated with the tractor. One or more components are shared between the first power system and the second power system.
Parking Cooler
A parking cooler which is capable of battery powered operation during engine off operation. The parking cooler or air conditioning system may vary in cooling capacities to maximize cooling or maximize battery life. The parking cooler includes one or more condensers and a housing to accommodate such variation of cooling capacity.
CASCADE HEAT TRANSFER SYSTEM
A transport refrigeration system (TRS) includes a first heat transfer circuit including a first compressor, a condenser, a first expansion device, and a cascade heat exchanger. The first compressor, the condenser, the first expansion device, and the cascade heat exchanger are in fluid communication such that a first heat transfer fluid can flow therethrough. The TRS includes a second heat transfer circuit including a second compressor, the cascade heat exchanger, a second expansion device, and an evaporator. The second compressor, the cascade heat exchanger, the second expansion device, and the evaporator are in fluid communication such that a second heat transfer fluid can flow therethrough. The first heat transfer circuit and the second heat transfer circuit are arranged in thermal communication at the cascade heat exchanger such that the first heat transfer fluid and the second heat transfer fluid are in a heat exchange relationship at the cascade heat exchanger.
INTERNAL CLIMATE CONTROL SYSTEM
A method and system for enabling climate control is provided. The method includes monitoring a refrigerated section of a vehicle. The refrigerated section includes a first cargo container comprising a first cargo type and first sensors describing the first cargo type. A cooling apparatus of the vehicle is currently maintaining a first specified temperature range within the refrigerated section. Second integrated cargo sensors describing a second cargo type of a second cargo container being placed within the refrigerated section of the vehicle are detected and associated data is analyzed. A second specified temperature range for storing the second cargo type is determined and compared to the first specified temperature range. An associated difference is compared to a temperature range threshold value and a response action associated with the first cargo container and the second cargo container is executed.
