    • An air cargo container temperature control system and method utilizing multiple refrigeration circuits and a controller that activates one or more of the refrigeration circuits in various modes to maintain temperature control. Each of the refrigeration circuits comprises a compressor, a condenser, and an evaporator all in fluid communication to form each refrigeration circuit. Additionally, heating elements are positioned in an evaporator cell for heating load space air and/or defrosting evaporator coils. The system is also provided with a battery pack having a transformer and battery chargers for charging corresponding battery cells by transforming power from an external source. The method compares a measured temperature to a set point temperature and activates one or more refrigeration circuits depending on the temperature difference.

    • A method of operating an internal combustion engine of a vehicle in an environment having an ambient temperature below about 0 degrees Celsius. The engine can include a battery and an engine body supporting a piston. The method can include the acts of initiating a first heating operation to warm air entering the engine, igniting fuel in the engine body to warm the engine and causing limited movement of the piston relative to the engine body, drawing power from the battery to generate heat in the battery, distributing the heat through the battery for a predetermined period of time before initiating a second heating operation to warm the air in the engine, and starting the internal combustion engine after the heat is distributed through the battery, causing the piston to continually reciprocate through the engine body.

    • A method of operating a refrigeration system having a discharge port that guides conditioned air from the system to a conditioned space and a return port that guides air from the conditioned space back to the system. The method comprises providing a first control algorithm and second control algorithm for controlling the system. The first control algorithm is a function of the air temperature at the discharge port, and the second control algorithm is a function of the air temperature at the return port. The method further comprises operating the system using the first control algorithm when a first condition is met, operating the system using the second control algorithm when a second condition is met, and automatically switching between the first control algorithm and the second control algorithm depending on the status of the first and second conditions.

    • A method for controlling at least one electronic expansion valve coupled to an economizer in a refrigeration system in order to dynamically control the refrigeration system operating conditions and in order to accommodate more than one set of operating conditions. The system can also be used to control the capacity of the system. More specifically, the method can include determining the required capacity of the system and adjusting the flow of refrigerant through the electronic expansion valve to adjust the actual capacity of the system toward the required capacity of the system. In another aspect of the invention, the system is operated to maintain the power of the system below a threshold value (e.g., below a max rated horsepower). This method includes determining the power required to operate the compressor based on the measurement of system parameters; comparing the power required to a threshold value; and adjusting the flow of refrigerant through the electronic expansion valve in order to keep the power required below the threshold value. In yet another aspect of the invention, the system is operated in order to prevent overheating of the compressor. More specifically, the flow of refrigerant from the heat exchanger to the compressor can be adjusted so that some amount of liquid refrigerant is provided to quench the compressor.
