ABSTRACT:
The present invention provides a conduit trap, which can also operate as condensation recovery device when installed in a refrigeration system drainage line. The conduit trap is generally a hollow body defining a fluid path that includes an upper conduit20, having a waste outlet30and optionally a condensation collection outlet32. A lower conduit22extends downwardly from the upper conduit and has a narrowing that creates an inner sealing region for receiving a sealing means, such as float50. Condensation can be directed from the refrigeration system through the conduit trap for recovery or for disposal without exposing the refrigeration drainage line and occupied space in which the refrigeration unit is located to sewer gasses even in dry weather when a gravity based, fluid-filled trap would fail.
