Abstract
An HVAC system is provided. Embodiments of the present disclosure generally relate to heat exchangers having tubing with a reduced diameter compared to traditional systems. In one embodiment, a ducted HVAC system comprises an outdoor heat exchanger with tubing that has an outer diameter of eight millimeters (8 mm) or less and an indoor heat exchanger with tubing that has an outer diameter of nine millimeters (9 mm) or less. Additional systems, devices, and methods are also disclosed.
Claims8
An HVAC system for providing conditioned air to a structure:
- a side-flow outdoor unit comprising a housing and a first heat exchanger within the housing, wherein the first heat exchanger has a tubing outer diameter that is less than or equal to eight millimeters (8 mm);
- a second heat exchanger configured to be coupled to the first heat exchanger for circulation of a fluid refrigerant between the first and second heat exchangers, wherein the second heat exchanger has a tubing outer diameter that is less than or equal to nine millimeters (9 mm);
- an airflow circulation system configured to circulate air from the structure over the second heat exchanger and then route the air back to the structure via ductworks;
- wherein the first and second heat exchangers are coiled-tube heat exchangers;
- and
- wherein the tubing outer diameter of the first coiled-tube heat exchanger is smaller than the tubing outer diameter of the second coiled-tube heat exchanger.
