Abstract
A transport refrigeration system comprises: a container (22) having a doorway (27) with at least one door (26); a refrigeration system (30) including a reversible first fan (82) for driving air (512) along an air flowpath and a heat absorption exchanger (80) along the air flowpath for cooling the air; and a second fan (100) positioned to in at least one mode of operation drive an air curtain flow (520 1) downward across the doorway.

A transport refrigeration system comprising:
- a container (22) having a doorway (27) with at least one door (26);
- a refrigeration system (30) including:
- a reversible first fan (82) for driving air (512) along an air flowpath;
- and
- a heat absorption exchanger (80) along the air flowpath for cooling the air;
- and
- a second fan (100) positioned to in at least one mode of operation drive an air curtain flow (520-1) downward across the doorway.
A method for operating a refrigerated transport system having a container (22) having a doorway (27) and a door (26), the method comprising:
- operating in a first mode with the door closed comprising driving an airflow along a flowpath passing through a heart exchanger acting as a heat absorption heat exchanger, the flowpath extending upward along a leg adjacent the door;
- and
- operating in a second mode with the door opened comprising:
- driving a first airflow along a flowpath passing through heat exchanger, the flowpath extending downward along a first air curtain leg adjacent the doorway;
- and
- driving a second airflow downward along a second air curtain leg adjacent the first air curtain leg.
