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.
Claims20
A beating, ventilation, and air-conditioning (“HVAC”) system for providing conditioned air to a structure, comprising:
- an outdoor unit external to the structure, the outdoor unit comprising an outdoor heat exchanger comprising a first tubing with an outer diameter less than or equal to eight millimeters (8 mm);
- an indoor heat exchanger disposed within the structure and coupled to the outdoor heat exchanger, the indoor heat exchanger comprising a second tubing with an outer diameter less than ⅜ inch, wherein the outer diameter of the first tubing is smaller than the outer diameter of the second tubing;
- an airflow circulation system operable to circulate air from the structure over the indoor heat exchanger and then route the air back to the structure via ductworks;
- and
- at least one electronic expansion valve in fluid communication with at least one of the outdoor or indoor heat exchangers and configured to reduce a pressure of a refrigerant flowing through the at least one electronic expansion valve.
A heating, ventilation, and air-conditioning (“HVAC”) system for providing conditioned air to a structure, comprising:
- an outdoor unit external to the structure and comprising an outdoor heat exchanger comprising tubing with an outer diameter less than or equal to eight millimeters (8 mm);
- an indoor unit disposed within the structure and comprising an indoor heat exchanger coupled to the outdoor heat exchanger and comprising non-circular channel tubing comprising channels, each channel with an outer diameter of less than or equal to eight millimeters (8 mm), wherein the outer diameter of each channel of the indoor heat exchanger is smaller than the outer diameter of the tubing of the outdoor heat exchanger;
- and
- at least one electronic expansion valve in fluid communication with at least one of the outdoor heat exchanger or the indoor heat exchanger and configured to reduce a pressure of a refrigerant flowing through the at least one electronic expansion valve.
A heating, ventilation, and air-conditioning (“HVAC”) system for providing conditioned air to a structure, comprising:
- an outdoor unit disposed external to the structure and comprising an outdoor coiled-tube heat exchanger comprising a first tubing with an outer diameter less than or equal to eight millimeters (8 mm);
- an indoor unit disposed within the structure and comprising an indoor coiled-tube heat exchanger coupled to the outdoor coiled-tube heat exchanger and comprising a second tubing with an outer diameter less than or equal to nine millimeters (9 mm), wherein the outer diameter of the first tubing is smaller than the outer diameter of the second tubing;
- a first electronic expansion valve in fluid communication with the outdoor coiled-tube heat exchanger and configured to reduce a pressure of a refrigerant flowing through the first electronic expansion valve;
- a second electronic expansion valve in fluid communication with the indoor coiled-tube heat exchanger and configured to reduce the pressure of the refrigerant flowing through the second electronic expansion valve;
- and
- an airflow circulation system operable to circulate air from the structure over the indoor coiled-tube heat exchanger and then route the air back to the structure via ductworks.
