摘要： An illustrative example embodiment of a transport refrigeration system includes an evaporator air management system having an evaporator heat exchanger and an air passage downstream of the evaporator heat exchanger. A two-stage fan assembly within the air passage includes a first fan stage having a first fan rotor, a first motor associated with the first fan rotor for selectively causing the first fan rotor to rotate in a first direction about a fan axis, a second fan stage having a second fan rotor in series with the first fan rotor, and a second motor associated with the second fan rotor for selectively causing the second fan to rotate in a second, opposite direction about the fan axis. The first and second fan stages draw air across the evaporator heat exchanger and through the air passage.

摘要： A device for analyzing and discriminating faults in an HVAC system. The device comprises acoustic sensor(s) to monitor acoustic parameters associated with component(s) of the HVAC system, and electrical sensor(s) to monitor one or more electrical parameters associated with the component(s) of the HVAC system. The device comprises a processing unit in communication with the acoustic sensor(s) and the electrical sensor(s). The processing unit is configured to receive, from the acoustic sensor (s), the acoustic parameters being monitored within the HVAC system, receive, from the electrical sensor(s), the electrical parameters associated with the component(s) of the HVAC system, and analyze one or more of the received acoustic parameters, and the electrical parameters to detect and discriminate one or more faults in the component(s) of the HVAC system.

摘要： A method for setting cooling parameters for a refrigerated transport vehicle includes receiving, from the transport vehicle, first information including energy consumption and performance parameters associated with the transport vehicle, and second information including vehicle type information and transit information associated with the transport vehicle. The method further includes retrieving historical data associated with peer transport vehicles similar to the transport vehicle based on the second information and identifying a peer transport vehicle for which energy and fuel consumption is minimum based on the second information and the retrieved historical data. Upon determining that the energy consumption and the performance parameters of the transport vehicle are greater than the energy consumption and the performance parameters of the identified peer transport vehicle, the method further includes controlling setting of the cooling parameters of the transport vehicle based on the cooling parameters of the identified peer transport vehicle.

摘要： A system and method for operating a plurality of evaporator units is disclosed. The method includes receiving, by a controller communicably coupled to each evaporator unit, a current state of operation of the respective evaporator unit. A state of operation of each evaporator unit includes first and second modes of operation. The method includes receiving, by the controller, a current speed of a fan of the respective evaporator unit. Responsive to the state of operation of the plurality of evaporator units, the method further includes operating, by the controller, each of the plurality of evaporator units, to change the speed of the respective fans from a first speed to a speed different from the first speed. Operation of the fans of the plurality of evaporator units at the speed different from the first speed enables the plurality of evaporator units to operate within a desirable range of cooling efficiency.

摘要： Cooling units are provided. The cooling units include a base having a housing with control components and a cooling tower attached to the base having an inner flow path and an exterior surface. An air distribution system is attached to the cooling tower and includes an air distribution chamber defined between the first and second enclosures and a cover is disposed on an exterior surface of the second enclosure. A plurality of dispersing apertures are formed within the first enclosure to generate a curtain of cool air to be dispensed from the air distribution system. The control components are configured to convey air through the base, the cooling tower, and the air distribution system to dispense air through the cool air dispenser and the warm air dispenser.

摘要： A method of authenticating a request from an IoT device includes the step of receiving a request from an IoT device for restricted access information. A location of an authorized user of the restricted access information is identified based on at least one location criteria of the authorized user. Access of the restricted access information to the IoT device is granted when the authorized user satisfies the at least one location criteria and denying access to the IoT device of the restricted access information when the authorized user fails the at least one location criteria.
