    摘要: A system is provided including a vapor compression cycle. The vapor compression cycle includes an operably coupled compressor, condenser, first expansion device, and evaporator through which a refrigerant circulates. A thermal energy storage unit includes a heat exchanger arranged within a phase change material. The heat exchanger is fluidly coupled to the vapor compression cycle with a plurality of conduits and valves such that refrigerant flows through the heat exchanger in a heat transfer relationship with the phase change material. When the system is in a first mode, the heat exchanger is configured to function similar to the evaporator and the phase change material is configured to store thermal energy. When the system is in a second mode, the heat exchanger is configured to function similar to the condenser and the phase change material is configured to release thermal energy.

    摘要: A transport refrigeration system includes a transport refrigeration unit, an energy storage device, a supply refrigerant tube, a return refrigerant tube and at least one electrical pathway. 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. 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.
