Abstract: The present disclosure relates to a heat exchanger including a tube having a length, and a cross-sectional geometry defined by an inner boundary and an outer boundary extending along the length. The tube is configured to flow a refrigerant fluid within the inner boundary to transfer heat. The cross-sectional geometry varies at respective transition points along the length of the tube. The tube is seamless and undeformed at the transition points.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes an enclosure and an evaporator coil disposed within the enclosure. The HVAC system also includes a pivot member coupled between an edge portion of the evaporator coil and the enclosure. The pivot member is configured to enable the evaporator coil to pivot relative to the enclosure to adjust an operating angle of the evaporator coil during operation of the HVAC system. Additionally, the HVAC system includes an actuator configured to enable pivoting of the evaporator coil to a target operating angle based on an operating parameter input.

Abstract: The present disclosure relates to an adjustable fluid flow system for a temperature control system having a heat exchanger including a plurality of channels configured to transmit working fluid and direct the working fluid through a selection of two or more channel sections. The adjustable fluid flow system includes a first chamber defining a first flow path that is aligned with a first channel section of the two or more channel sections, wherein the first chamber includes a first outlet in fluid communication with the first flow path, and a second chamber defining a second flow path that is aligned with a second channel section of the two or more channel sections, wherein the second chamber includes a second outlet in fluid communication with the second flow path. The adjustable fluid flow system further includes a damper configured to adjust a flow of air along the first flow path.
