  • Patent number: 12157346
    Abstract: An environmental control system for thermally conditioning air within an enclosed space comprising: a refrigerant circuit having a compressor, an indoor heat exchanger, an expansion device, and an outdoor heat exchanger. The system further comprises an intake flowpath for directing an intake flow of fresh air to the enclosed space, wherein a heat-transfer section of the indoor heat exchanger is located within the intake flowpath to thermally condition the intake flow of fresh air before entering the enclosed space. The system further comprises an exhaust flowpath for directing an exhaust flow of thermally conditioned air to an external environment. A recovery heat exchanger is configured to transfer thermal energy between the exhaust flow and the intake flow at a location within the intake flowpath that is upstream of the heat-transfer section of the indoor heat exchanger.

  • Patent number: 9908386
    Abstract: A system and method for controlling a transport heating, ventilation, and air conditioning (HVAC) system having a fresh air intake is disclosed. The fresh airflow intake system includes a fresh air damper configured to regulate a flow of fresh air into the transport HVAC system, an evaporator fan having at least a high-speed mode and a low speed mode, and a controller. The controller is configured to determine whether a fresh air condition is met and increase a fresh airflow in response to determining the fresh air condition is met. The controller is further configured to increase an evaporator fan speed when the fresh airflow is increased.
