AIR CONDITIONING METHOD OF ENGINE ROOM IN ARCTIC SHIP

摘要

The present invention relates to an air conditioning method of an engine room in an arctic ship. When supplying air at a temperature of approximately 5C into an engine room in a vessel navigating in an arctic region where a temperature of outer air is approximately -52C, one sea water between sea water at a temperature of approximately -4C and warm sea water at a temperature of approximately 40C which passed through a water cooler of the engine room is utilized as a heat source. By providing outer air at a temperature of approximately -52C after preheating the outer air to approximately 5C, energy (steam or electric power) consumed for directly heating the outer air of -52C to supply air of 5C required in the engine room can be drastically saved. According to the present invention, the air conditioning method of the engine room in an arctic ship comprises: a first step of transferring a lower temperature outer air into a heat exchange chamber; a second step of performing heat exchange; a third step of removing moisture included in heat exchanged air; a fourth step of inducing air without moisture into a second duct; a fifth step of mixing the low temperature outer air with the air discharged from the second duct; a sixth step of heating the mixed air; a seventh step of transferring the heated air into a third duct; an eighth step of determining whether or not the temperature of the air in the third duct is a desired temperature; a ninth step of stopping heating the air if the temperature of the air in the third duct is determined to be at the desired temperature; and a tenth step of blowing the air in the third duct to the engine room.
