Abstract: A heat transfer tube and a heat exchanger incorporating at least one heat transfer tube are provided. The heat transfer tube and the heat exchanger are optimized for use within an air conditioner (which is configured to operate only in a cooling mode). The heat transfer tube includes a tube body with an interior surface and an exterior surface. The tube body defining an outer diameter (Do) and a wall thickness (WT), wherein a ratio (WT/Do) the wall thickness (WT) to the outer diameter (Do) is between 0.061 and 0.071. The heat transfer tube includes multiple pluralities of adjacent helical fins protruding circumferentially around the interior surface of the tube body at respective helix angles. The multiple pluralities are separated by one or more transition area(s).

Abstract: A heat transfer tube and a heat exchanger incorporating at least one heat transfer tubes are provided. The heat transfer tube and the heat exchanger are configured to operate in both a heating mode and a cooling mode (e.g., to optimize the reversible function a heat pump). The heat transfer tube includes a tube body with an interior surface and an exterior surface. The tube body defining an outer diameter (Do) and a wall thickness (WT), wherein a ratio (WT/Do) the wall thickness (WT) to the outer diameter (Do) is between 0.061 and 0.071. The heat transfer tube includes a plurality of adjacent helical fins protruding circumferentially around the interior surface of the tube body, and at least one groove disposed between the plurality of adjacent helical fins. The configuration of the heat transfer tube(s) is optimal for the reversible function of the heat pump.

Abstract: The disclosure provides a method for protecting a tube of a heat exchanger. The method includes inserting at least one portion of a non-ferrous tube into a hole of a tube sheet of the heat exchanger. The at least one portion of the non-ferrous tube is then rolled to radially expand the at least one portion. The at least one portion expands and forms a seal with the hole. A sleeve is then affixed onto an inner surface corresponding to the at least one portion of the non-ferrous tube.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a vapor compression cycle comprising a heat exchanger and an expansion device arranged in fluid communication with the heat exchanger. A fluid is configured to circulate within the vapor compression cycle in a first direction during a first mode and is configured to circulate within vapor compression cycle in a second, opposite direction during a second mode. A receiver is fluidly coupled to the vapor compression cycle at a connection point. The connection point is positioned between the heat exchanger an the expansion device and the receiver is positioned vertically above the connection point.
