Abstract
A condensing heat exchanger system includes a first tube configured to receive a conditioning fluid, a second tube configured to receive the conditioning fluid from the first tube, a first vestibule panel coupled to the first tube, a second vestibule panel coupled to the second tube, and a drain trap assembly directly coupled to the second vestibule panel and configured to collect condensate.
Claims17
A condensing heat exchanger system, the condensing heat exchanger system comprising:
- a first tube configured to receive a conditioning fluid;
- a second tube configured to receive the conditioning fluid from the first tube;
- a first vestibule panel coupled to the first tube;
- a second vestibule panel coupled to the second tube, wherein the first vestibule panel and the second vestibule panel are coupled to one another, the first vestibule panel and the second vestibule panel are aligned with each other in a direction of an air flow through the condensing heat exchanger system, the first vestibule panel comprises a first material, and the second vestibule panel comprises a second material;
- an end plate coupled to the first tube and the second tube, wherein the end plate is disposed opposite the first vestibule panel and the second vestibule panel relative to the first tube and the second tube;
- an end cover coupled to the end plate, wherein the end plate and the end cover cooperatively define a compartment configured to receive the conditioning fluid from the first tube and direct the conditioning fluid to the second tube;
- and
- a drain trap assembly directly coupled to the second vestibule panel and configured to collect condensate.
A furnace, comprising:
- a first heat exchanger tube and a second heat exchanger tube fluidly coupled to one another;
- a first vestibule panel configured to couple to the first heat exchanger tube;
- a second vestibule panel configured to couple to the second heat exchanger tube, wherein the first vestibule panel and the second vestibule panel are each removably coupled to and individually removable from the furnace, the first vestibule panel and the second vestibule panel are aligned with each other in a direction of an air flow through the furnace, the first vestibule panel is formed from a first material, the second vestibule panel is formed from a second material different than the first material, and the second material is more corrosion resistant than the first material;
- and
- a drain trap assembly directly mounted to the second vestibule panel and configured to collect liquid formed within the furnace during operation of the furnace, wherein the drain trap assembly forms a cavity, and the second heat exchanger tube extends into the cavity.
A heat exchanger system, comprising:
- a first heat exchanger section, comprising:
- a first vestibule panel;
- and
- a first tube coupled to the first vestibule panel at an inlet of the first tube, wherein the first tube is configured to direct a fluid therethrough and transfer heat from the fluid to an air flow directed through the heat exchanger system;
- a second heat exchanger section, comprising:
- a second vestibule panel;
- and
- a second tube coupled to the second vestibule panel at an outlet of the second tube, wherein the second tube is fluidly coupled to the first tube, the second tube is configured to receive the fluid from the first tube, to direct the fluid therethrough, and to transfer heat from the fluid to the air flow directed through the heat exchanger system, the first vestibule panel and the second vestibule panel are separate components, the first vestibule panel and the second vestibule panel are coupled to one another and are aligned with each other in a direction of the air flow directed through the heat exchanger system, the first vestibule panel is formed from a first material, the second vestibule panel is formed from a second material different than the first material, and the second material is more corrosion resistant than the first material;
- and
- a drain trap assembly coupled to the second vestibule panel and forming a cavity, wherein the second tube of the second heat exchanger section extends into the cavity.
