Abstract: A transport refrigeration system (TRS), a refrigerated transport unit, and a method of charging a thermal accumulator in a TRS are disclosed. The TRS includes a thermal accumulator including a phase change material (PCM) configured in a first state, to absorb thermal energy from the interior space of the transport unit during transformation to a second state. A heat exchanger, a portion of which is disposed within the thermal accumulator, is in thermal communication with the PCM. The TRS also includes an expansion device and a transport refrigeration unit (TRU). A heat transfer fluid circuit connects the TRU and the heat exchanger, and is configured to direct a heat transfer fluid from the TRU to the heat exchanger via the expansion device for charging the PCM.

Abstract: An air conditioning system for motor-vehicles includes a thermally controlled expansion valve unit for regulating the expansion of the fluid upstream of the evaporator, depending upon the temperature downstream of the evaporator. An intermediate heat exchanger provides a heat exchange between the conduit upstream of the evaporator and the conduit downstream of the evaporator. The expansion valve unit is arranged in such a way that its temperature sensor detects a temperature of the fluid along the conduit downstream of the evaporator at a portion of this conduit which is located downstream also with respect to the intermediate heat exchanger. A connecting flange is interposed between the evaporator and the thermally controlled expansion valve unit.
