Although it is described in this embodiment that the air heated by the air heater 610 is mixed with the air introduced through the mixture circulation damper 140 in the air mixing chamber 600 and introduced into the blower chamber 700, the blower chamber 700 may receive only the air heated by the air heater 610 or only the air introduced through the circulation damper 140. Alternatively, the air supplied from the blower room 700 to the on-board air requiring place may be the air discharged from the air mixing chamber 600 or the air introduced through the blower room circulation damper 130.
Further, a first discharge line EL1 extending from the air heater 610 to the discharge control damper 230 to provide a flow passage of the exhaust gas discharged from the air heater 610 through heat exchange may be disposed through the air mixing chamber 600 such that the air in the air mixing chamber 600 may be further heated by the heat of the exhaust gas discharged from the air heater 610.
In this way, according to this embodiment, the air drawn into the intake chamber 500 is heated by the exhaust gas discharged from the air heater 610 and the engine 110, and then supplied to various air-requiring places including the engine room 100 and the machine room 200 using fans. Therefore, the air conditioning system of the polar vessel according to this embodiment does not need a separate expensive hot oil system having a complicated structure for heating air for air conditioning, thereby achieving a reduction in energy consumption and providing a simple configuration so as to reduce initial installation costs and maintenance costs. Further, the air conditioning system of the polar vessel according to this embodiment can prevent interruption of system operation due to leakage of hot oil.
In addition, the air conditioning system of the polar vessel according to this embodiment can reduce the total capacity by about 30% (7,500 kw→5,000 kw) compared to a typical system using a hot oil system to heat air for air conditioning.
Although some embodiments have been described herein, it is to be understood that these embodiments are provided for illustration only and are not to be construed as limiting the invention in any way, and that various modifications, changes, alterations, and equivalent embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention. The scope of the invention should be defined by the appended claims and equivalents thereof.
