Abstract
A double-walled pipe ventilation system is disclosed. The double-walled pipe ventilation system includes: an engine unit including a jacket cooling circulation unit dissipating heat generated by an engine; a fuel supply unit connected to the engine unit via a double-walled pipe and supplying fuel through an inner pipe of the double-walled pipe; an air outlet line along which air is discharged from an outer pipe of the double-walled pipe; an air circulation unit circulating the air discharged along the air outlet line; and a water ejector provided to the air circulation unit and suctioning air circulated through the outer pipe using a high-pressure working fluid introduced into the water ejector.
Claims13
A double-walled pipe ventilation system comprising:
- an engine unit comprising a jacket cooling circulation unit dissipating heat generated by an engine;
- a fuel supply unit connected to the engine unit via a double-walled pipe and supplying fuel through an inner pipe of the double-walled pipe;
- an air outlet line along which air is discharged from an outer pipe of the double-walled pipe;
- an air circulation unit circulating the air discharged along the air outlet line;
- and
- a water ejector provided to the air circulation unit and suctioning air circulated through the outer pipe using a high-pressure working fluid introduced into the water ejector.
A double-walled pipe ventilation method comprising:
- a fuel supply step in which fuel is supplied from a fuel supply unit to an engine unit through an inner pipe of a double-walled pipe;
- and
- an air circulation step in which air discharged through the air outlet line is circulated,
- wherein the air circulation step comprises suctioning air circulated through the outer pipe of the double-walled pipe by introducing a high-pressure working fluid into a water ejector provided to the air circulation unit.
