An air conditioning unit includes an air conditioning case, a connector that is attached to an end of a first pipe connected to a first heat exchanger, a second pipe connected to a second heat exchanger, and a gasket being a sheet in shape. The gasket includes a first opening and a second opening. The gasket is adhered to a contact surface of the air conditioning case with the connector inserted into the first opening and with the second pipe inserted into the second opening. The periphery of the second opening in the gasket is compressed by the second pipe. The gasket includes a surface including an adhesive area that includes at least a periphery of the first opening and an adhesive-less area that includes at least a periphery of the second opening. The adhesive is applied to the adhesive area and is not applied to the adhesive-less area.

An arrangement for de-icing a heat exchanger includes an air guiding housing and at least one fan. The air guiding housing is configured to take in an air from an outside of a motor vehicle through an inlet opening and to discharge the air from an outlet opening. The fan is positioned between the inlet opening and the outlet opening inside the air guiding housing and is configured to circulate the air in the air guiding housing. The heat exchanger is positioned between the inlet opening and the outlet opening inside the air guiding housing and allows the air to pass therethrough, thereby being configured to cool the air. The inlet opening and the outlet opening each are configured to be closed. The air guiding housing is configured to cause a circulation flow therein when the fan is operated while the inlet opening and the outlet opening are closed.

A transport refrigeration unit (13) is provided and includes a wall (510) defining an inlet (511) and an outlet (512) and a pod (530) attachable to the wall (510) to define, with a portion of the wall, an interior configured to accommodate a heat exchange portion of a heat exchanger (520), a fan (550) that drives air flow from the inlet (511) and to the outlet (512) through the heat exchange portion. The pod (530) is configured to isolate coolant flow control elements (522) of the heat exchanger (520) from the interior.

A method for servicing a heater core installed in a heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle includes removing a sealing attachment from an interfacing connection interfacing with the heater core. The method includes sliding the heater core in a direction of insertion. The method includes disconnecting, from the heater core, the interfacing connection.
