COMPRESSIBLE DEVICE FOR FREEZE MITIGATION

摘要

A system includes an enclosure and a compressible device. The enclosure forms a confined space where water can accumulate in ambient conditions that fluctuate between freezing and non-freezing water temperatures. The enclosure can contain a protected item within at least a portion of the confined space. The compressible device is within at least the portion of the confined space and compresses under pressure from an uncompressed state to a compressed state that increases the available volume for water within the confined space. The compressible device compresses from the uncompressed state to the compressed state under a first pressure force created by the expansion of frozen water within the enclosure. The first pressure force is less than a second pressure force capable of damaging the enclosure or the protected item.

主权项

1. A system, comprising:
an enclosure including a confined space where water can accumulate in ambient conditions that fluctuate between freezing and non-freezing water temperatures; a protected item within at least a portion of the confined space; and a compressible device, within at least the portion of the confined space, that compresses under pressure from an uncompressed state to a compressed state that increases the available volume for water within the confined space, wherein the compressible device compresses from the uncompressed state to the compressed state under a first pressure force created by the expansion of frozen water within the enclosure, and wherein the first pressure force is less than a second pressure force capable of damaging one of the enclosure or the protected item.
