    摘要： There is disclosed an environmental control system (110) for heating at least one enclosed space (14). The system (110) comprises a heat-pump circuit (22) that includes a compressor (30), a heat-output stage, an expansion device and an evaporator (314) arranged in series along a flow path for a refrigerant. The heat-output stage comprises a primary heat exchanger (34) and a secondary heat exchanger (36) that are both configured to transfer heat from the refrigerant to one or more external mediums in thermal communication with the at least one enclosed space (14). The primary heat exchanger (34) and the secondary heat exchanger (36) are connected in series along the flow path, such that the secondary heat exchanger (36) will transfer excess heat energy remaining within the refrigerant after passing through the primary heat exchanger (34) to the one or more external mediums.

    摘要： A method for charging a phase change material (PCM) of a thermal accumulator provided in a refrigerated transport unit is provided. The refrigerated transport unit includes a prime mover to move the refrigerated transport unit, a transport refrigeration system (TRS) that includes a heat transfer fluid circuit. The heat transfer fluid circuit has a compressor, a heat exchanger, an expansion device and a PCM heat exchanger. The method requires monitoring for, via a controller, a braking signal from a braking sensor of the refrigerated transport unit. Also, the method includes directing energy generated by the prime mover for moving the refrigerated transport unit to the TRS when the controller receives a braking signal from the braking sensor. Further, the method includes the TRS charging the PCM of the thermal accumulator via the heat transfer fluid circuit when the energy generated by the prime mover is directed to the TRS.
