Condensate trap for heating-cooling systems
A condensation trap comprising an inlet chamber, a vent chamber and an outlet chamber. The inlet chamber is configured to receive condensate fluid through an external opening therein. The vent chamber is in fluid communication with the inlet chamber via a first passageway that includes an internal opening of the inlet chamber. The internal opening is located substantially at an opposite end of the vent chamber as the external opening. The outlet chamber is in fluid communication with the vent chamber via a second passageway that includes an internal opening in a sidewall of the vent chamber and an interior opening in an end of the outlet chamber. The outlet chamber is configured to transmit the condensate fluid through an exterior opening located at an opposite end of the outlet chamber. A vent volume portion is greater than a total volume of an internal space of the inlet chamber.
1. A method of manufacturing a condensation trap, comprising:
providing a mold, said mold defining an enclosed cavity that includes spaces that define the condensation trap having:
an inlet chamber configured to receive condensate fluid through an external opening therein,
an vent chamber in fluid communication with said inlet chamber via a first passageway that includes an internal opening of said inlet chamber, said internal opening located substantially on an opposite end from said external opening, wherein the vent chamber shares a common sidewall with the inlet chamber,
an outlet chamber coupled to said vent chamber via a second passageway that includes an internal opening in a sidewall of said vent chamber and an interior opening in an end of said outlet chamber, said outlet chamber configured to transmit said condensate fluid through an exterior opening in an opposite end of said outlet chamber, and
wherein a vent volume portion, which includes an internal space of said vent chamber that is below said exterior opening, is greater than a total volume of said inlet chamber;
introducing a moldable material into said mold;
allowing said moldable material to solidify to a casting; and
removing said casting from said mold to provide said condensation trap.
2. The method of claim 1 , wherein introducing said moldable material includes a single-step injection-molding process.
3. The method of claim 1 , wherein the enclosed cavity that includes spaces that define the condensation trap further includes an intermediate chamber located between said inlet chamber and said vent chamber, wherein an internal space of said intermediate chamber located below said exterior opening is part of said vent volume portion, and wherein said fluid communication from said inlet chamber to said vent chamber includes said intermediate chamber.
