摘要： Methods and systems for operating a transport climate control system of a vehicle are provided. The method includes obtaining a state of charge of an energy storage device capable of providing power to the transport climate control system; determining an energy level including the state of charge, receiving a planned route for the vehicle, and receiving route status data associated with the planned route for the vehicle. The route status data includes traffic data, weather data, and/or geographic data identifying areas where the transport climate control system is to be solely powered by the energy storage device. The method further includes determining whether the energy level is sufficient to complete the planned route for the vehicle based on the planned route and the route data, and when the energy level is not sufficient to complete the planned route for the vehicle, providing a notification to a user via a display.

摘要： A transport climate control system for a climate controlled transport unit includes a main heat transfer circuit and a chiller heat transfer circuit. The main heat transfer circuit includes a compressor, a condenser, a main expansion valve, a main evaporator, a chiller expansion valve, and a chiller evaporator. The main evaporator and a chiller evaporator positioned are in parallel to each other downstream of the condenser. Working fluid and a second process fluid flowing through the main evaporator. Working fluid and a third process fluid flowing through the chiller evaporator. The chiller heat transfer circuit includes the chiller evaporator and the third process fluid is configured to provide auxiliary cooling. A method of operating a transport climate control system for a climate controlled transport unit includes operating in a HVACR and chiller mode, operating in a HVACR mode, and operating a chiller mode.

摘要： Methods and systems for controlling a transport refrigeration system are provided. In one instance, the method includes identifying an operational mode change request for a heat exchanger unit of the transport refrigeration system. The method also includes preparing the transport refrigeration system for the operational mode change of the heat exchanger unit, wherein preparing the transport refrigeration system for the operational mode change of the heat exchanger unit includes performing a load control action, the load control action preventing a power source of the transport refrigeration system from at least one of operating outside of a predefined revolutions per minute (RPM) bandwidth and exceeding a predefined power limit of the power source. Also, the method includes changing the operational mode of the heat exchanger unit; and removing the load control action.

摘要： Systems and methods to control a prime mover of a transport refrigeration system are disclosed. A controller may be configured to receive input from various information sources including a global satellite positioning system and/or a human machine interface. The controller can be configured to select a prime mover operation mode based on the input received. In some embodiment, the controller can select a noise reduction operation mode when the TRU is located in a noise regulated area, and can select a fuel efficient mode when the TRU is located outside of the noise regulated areas. In some embodiments, the noise reduction operation mode may include increasing a speed of the prime mover in a soft sloped ramp. In some embodiments, the operation modes can include prime mover operation instructions containing parameters of fuel injection of the prime mover. The operation instructions can be sent to an ECU to execute.

摘要： Methods and systems for monitoring belt tension and determining belt lifespan in a TRS are disclosed. An embodiment of a self-tensioner can include a sensor connected to a self-tensioner in a belt driven system and a magnet that passes over the sensor to generate a signal. The sensor detects the signal, and the signal in conjunction with an angle of the magnet is converted into a voltage value. The method can include a controller connected to the self-tensioner, the controller converts the voltage value into a tension value, and stores the tension value among a plurality of premeasured tension values in a memory, where the controller compares the tension value and the plurality of premeasured tension values to determine a belt tension condition of the belt in the belt-driven system.

摘要： An internal oil filter is installed at least partially inside a crankcase and/or an oil sump of a compressor. The internal oil filter can receive oil from an oil pressure regulator and filter the oil via filter media. The received oil radially penetrates through the filter media and flow directly into the oil sump from an outside surface of the filter media. This can eliminate the need of fluid lines connecting an outlet of an oil filter to the oil sump and any sealing mechanism therebetween.
