Microchannel heat exchanger for heat pump

A heating, ventilation, and air conditioning (HVAC) system comprising:

• a vapor compression cycle comprising a microchannel heat exchanger, wherein 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 the vapor compression cycle in a second, opposite direction during a second mode;
• and
• a receiver integrally formed with the microchannel heat exchanger, the microchannel heat exchanger having:
• a first manifold;
• a second manifold;
• a plurality of heat exchange tubes extending between and fluidly coupling the first manifold and the second manifold, the plurality of heat exchange tubes having a plurality of discrete flow channels formed therein;
• and
• a plurality of dummy tubes mechanically connected to at least one of the first manifold and the second manifold, wherein at least one dummy tube of the plurality of dummy tubes configured as the receiver.
