Abstract: A heating, ventilation, and air conditioning (HVAC) system (10) includes a flash tank (32) configured to receive a refrigerant and to separate the refrigerant into vapor refrigerant and liquid refrigerant. The flash tank (32) is configured to generate a flow of refrigerant therein along a circular flow path (132). The flash tank (32) has a main body (102) having a circular cross-section with a diameter (112) and an inlet (100) coupled to the main body (102) and configured to direct the refrigerant into the main body (102). The inlet (100) has a center line (110) extending in a common direction with the diameter (112), and the center line (110) is offset from the diameter (112) in a radial direction.

Abstract: A heat exchanger (100) of a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a plurality of microchannel tubes (104, 106), where each microchannel tube (104, 106) of the plurality of microchannel tubes (104, 106) is configured to direct refrigerant therethrough, and a plurality of fin sets (116), where each fin set (116) of the plurality of fin sets (116) is disposed between corresponding adjacent microchannel tubes (104, 106) of the plurality of microchannel tubes (104, 106). Additionally, each fin set (116) of the plurality of fin sets (116) includes a respective fin density based on a location of the respective fin set (116) along a height (112) of the heat exchanger (100).
