Abstract
A condensate drain system for a furnace incorporates a collector and blower housing assembly mounted above a secondary condensing heat exchanger with condensate ports between the blower housing and the collector housing positioned to assure flow of all condensate from the exhaust flue and the blower housing to the collector housing. A pipe extends downwardly from the collector housing to the condenser outlet manifold so that all condensate ultimately flows to the condenser outlet manifold and can be discharged to a drain by a single tube.
Claims19
A condensate drain system for a furnace of the kind having a condenser with an outlet section comprising:
- a blower housing having a compartment with a blower fan therein,
- means for mounting the blower housing above the condenser,
- an outlet port communicating with an upper portion of the compartment and a flue pipe connected to the outlet port,
- passage means between the condenser outlet section and the blower housing for conveying to the blower compartment combustion products and condensate conveyed to the outlet section from the condenser,
- said passage means communicating with the blower compartment at a lowermost area thereof whereby condensate flowing from the flue pipe and blower compartment to the bottom of the blower compartment can enter the passage means and flow by gravity to and collect in the condenser outlet section,
- and a drain tube connected from the condenser outlet section for conveying condensate therefrom.
A condensate drain system for a furnace of a kind having a heat exchanger that produces condensation of water and having means for conveying condensate from an outlet of the heat exchanger to a drain, the condensate drain system comprising:
- a collector housing located above the heat exchanger,
- a blower housing and a blower supported thereby,
- suction passage means between the collector housing and the blower housing for the passage of combustion products drawn by the blower into the blower housing from the collector housing,
- means for connecting the heat exchanger outlet to the collector housing for the transfer of combustion products from the heat exchanger to the collector housing,
- an exhaust flue connected to an upper portion of the blower housing, and passage means between a lowermost portion of the blower housing and the collector housing for conveying condensate from the blower housing to the collector housing.
A condensate drain system for a furnace of the kind having a heat exchanger comprising:
- blower housing having a compartment with a blower fan therein,
- a collector housing surrounding a collector chamber,
- the collector chamber having an inlet for receiving combustion products from the heat exchanger,
- the collector chamber having an outlet for discharging combustion products,
- the blower compartment having an inlet communicating with the collector chamber outlet,
- the blower compartment having an outlet from an upper area thereof for discharging combustion products to a flue pipe,
- an upper condensate port between the blower compartment and the collector chamber,
- means for intercepting condensate dripping through the blower outlet and for diverting the condensate to the upper condensate port,
- a lower condensate port between the blower compartment and the collector chamber,
- the lower condensate port being substantially as low as the lowest area of the blower compartment.
A system for collecting and draining condensate from a heating apparatus comprising;
- a blower means;
- a condenser means;
- and
- a passage means between the condenser means and the blower means, the passage means being adapted to convey combustion products and condensate from the condenser means to the blower means, and also being adapted to collect, substantially all of the condensate conveyed and drain the condensate from the heating system.
A condensate drain system for a furnace having a condenser, the system comprising:
- a blower means adapted to eject combustion products from the furnace;
- a passage means extending between the condenser and the blower means, the passage means being adapted to conduct combustion products and condensate from the condenser to the blower means, and being adapted to collect substantially all of the condensate from the blower means, the passage means, and the condenser and to drain condensate collected from the furnace.
