摘要:
A method of powering a refrigeration system. The method includes providing a mover and an alternator, the alternator being coupled to the mover and generating a power signal. The method also includes monitoring at a control a plurality of system parameters and sending a control signal based on the system parameters from the control. The method further includes receiving the power signal and the control signal at an inverter-based device which has a plurality of inverters, converting the power signal into a controlled power signal based on the control signal, and driving a plurality of components of the refrigeration system with the controlled power signal, which are also controlled by the control.

A temperature control system for a container includes a refrigeration circuit having a primary fluid circulating therein and a secondary fluid circuit in communication with a first compartment of the container and a second compartment of the container. The secondary fluid circuit has a secondary fluid separate from the primary fluid circulating therein. The secondary fluid circuit includes a first heat exchange module in communication with an interior load space of the first compartment and a second heat exchange module in communication with an interior load space of the second compartment. Each of the first and second heat exchange modules includes a pump, a heater, a heat exchanger, and a three-way valve. A heat exchange interface between the refrigeration circuit and the secondary fluid circuit is operable to transfer heat from the secondary fluid to the primary fluid.

A transportation refrigeration system operable in a cooling mode, a defrost mode, and a heating mode to condition air in an air-conditioned space. The system comprises a refrigeration circuit fluidly connecting a compressor, a condenser, a tank, and an evaporator. The evaporator is in thermal communication with the air-conditioned space. A heating circuit fluidly connects the compressor, the tank, the evaporator, and a heater. A defrost circuit fluidly connects the compressor, the tank, the evaporator, and the heater. The tank has a base and the first opening is spaced a first distance above the base and the third opening is spaced a second greater distance above the base.
摘要:
A method of controlling a compressor in a transport temperature control unit having a prime mover providing power to the compressor. The compressor has a power requirement that varies depending on loading conditions. The method includes determining the maximum power available from the prime mover, determining the power requirement of the compressor, and adjusting the loading conditions of the compressor so that the power requirement of the compressor substantially equals the maximum power available from the prime mover. Preferably, the method includes starting the compressor at a low speed, varying the suction pressure as permitted by the maximum amount of power available until the suction pressure reaches a maximum suction pressure setting, and after the suction pressure reaches a maximum suction pressure setting, increasing the speed of the compressor as permitted by the maximum-amount of power available.

A slave communication device includes a memory and a processor for operation within a wireless mesh network of communication devices including a control communication device. The memory stores a virtual routing identifier assigned to the slave communication device in response to increasing range from the control communication device. The processor, in response to receiving an initiation message from a control communication device, initiates data collection from said slave communication device synchronized relative to the start of the initiation message frame by, cumulatively setting bits in a first acknowledgement message in response to content of a second acknowledgement message received from another slave communication device. The first acknowledgement message being synchronized with start of the initiation message frame and the processor initiates communication of the first acknowledgement message to a destination in a time slot selected in response to the assigned virtual routing identifier.
摘要:
A temperature control system includes a compressor, a condenser, an evaporator, a receiver, and an accumulator. A valve is positioned between the evaporator and the receiver. An evacuation line has a first end in fluid communication with heat transfer fluid between the valve and the receiver, and a second end in fluid communication with the accumulator. The evacuation line provides for flow of the heat transfer fluid from both of the first heat exchanger and the receiver to the accumulator during an evacuation mode of operation of the temperature control system. The valve can take the form of a check valve or an expansion valve without a bleed port.
