A tractor trailer system includes a tractor and a trailer. The tractor includes a hotel device and an Auxiliary Power Unit (APU) configured to provide electrical power to the hotel device. The trailer is connected to the tractor, and includes a Transport Refrigeration Unit (TRU) having a TRU controller, an electrical TRU component, and a TRU Power Unit. The TRU controller is configured to utilize the APU to provide electrical power to the electrical TRU component during low TRU load conditions, and utilize the TRU Power Unit during high TRU load conditions.

Beverage coolers for storing and cooling bottled beverages. A beverage cooler may include a cooling chamber cooled by a refrigeration system, and openings in the cooling chamber for receiving bottled beverages to be chilled. The openings may have doors and/or seals to minimize heat exchange between the cooling chamber and the environment with or without bottles disposed in the openings. Each of the openings may have a visual indicator, such as a plurality of LEDs, configured to indicate the temperature of the bottle disposed in the opening.

A method of monitoring a health of a transportation refrigeration unit including: receiving at least one of an alarm of one or more components of the transportation refrigeration unit, test data on the one or more components of the transportation refrigeration unit, historical trip data of the transportation refrigeration unit, or service data of the transportation refrigeration unit; receiving reefer parameters of the transportation refrigeration unit; determining a health score of the transportation refrigeration unit based on at least the reefer parameters; and determining a maintenance action for transportation refrigeration unit based on the health score and at least one of the alarm, the test data, the historical trip data, or the service data.

A transport refrigeration system (26) includes a transport refrigeration unit (44), an energy storage device (46), a supply refrigerant tube (108), a return refrigerant tube (110) and at least one electrical pathway (98). The transport refrigeration unit is adapted to cool a container. The energy storage device is adapted to provide electrical energy for operating the transport refrigeration unit. The supply refrigerant tube flows a refrigerant from the transport refrigeration unit to the energy storage device, and the return refrigerant tube flows the refrigerant from the energy storage device back to the transport refrigeration unit to cool the battery in the energy storage device (46). The electrical pathway extends between the transport refrigeration unit and the energy storage device, and supplies at least electrical energy to the transport refrigeration unit.

A container energy storage system is provided in this disclosure. The system includes a container and a plurality of functional assemblies. The container includes a container frame and a bottom plate. The container frame is formed a plurality of openings and a hollow main body. The bottom plate is disposed at the bottom of the container frame and is fixedly connected to the container frame. The functional assemblies are disposed in the hollow main body and located above the bottom plate.

In an example, a transformable cargo container for use with ground and air transportation vehicles is disclosed. The cargo container includes a main container body defining a storage chamber therein and including at least one inlet. The cargo container also includes a transformable assembly coupled to the main container body and positioned at an exterior of the main container body. The transformable assembly includes one or more supplemental containers and one or more supply ducts, at least one of the supplemental container(s) being configured to house refrigeration equipment. The transformable assembly is movable between an aircraft configuration and a ground configuration. Based on the transformable assembly being in either the aircraft configuration or the ground configuration, the refrigeration equipment is configured to supply coolant into the main container body via the supply duct(s) and the inlet(s).

The present invention relates to a grain refrigerator including a housing having a grain storage space formed thereon to discharge grains stored therein, a fixing rod located at the center of the inside lower portion of the housing, dew condensation prevention means fixed to the fixing rod, a support plate located on a top periphery of the dew condensation prevention means, an evaporator disposed on the support plate to generate cool air, and a cooling tube disposed on a top periphery of the support plate on the outside of the evaporator to cool the grains, wherein a first pipe and a second pipe connected to the lower portion of the evaporator pass through a through hole of the support plate and a first drain hole of the dew condensation prevention means and are thus exposed to the outside of the housing.
