Definitions

  • the presented solution concerns an air-conditioning system for a passenger ship.
  • the presented solution also concerns a passenger ship provided with the mentioned air-conditioning system.
  • An air conditioning system for the cruise vessel is mainly intended for the air conditioning of different areas of the deck of passenger cabins, comprising, among others, passenger cabins, corridors, storage rooms and toilets.
  • the air-conditioning system typically comprises an air handling unit, AHU, which takes in fresh air from outside and, for example, filters it and either heats or cools it, and supplies it to the ventilated areas.
  • Fresh air is led from a supply air duct of the air handling unit via a ductwork to passenger cabins and other areas.
  • Air pressure, temperature and/or humidity can additionally be adjusted to desired values by using a fan coil device installed in the passenger cabin.
  • Return air extracted from the passenger cabins is led back to the air handling unit and its return duct by means of a ductwork.
  • Air handling units become relatively large-scale and they take a lot of space, when they serve passenger cabins of three floors or more.
  • Horizontal ducts providing fresh air to the air handling units from outside the ship and extracting return air from the ship also become large and voluminous.
  • a passenger ship is usually divided into successive fire compartments comprising several floors. There are own air handling units for each fire compartment so that together they take up a lot of space.
  • Passenger cabins are typically placed successively on both sides of the passenger ship to a multi-storey deck structure situated above the deck of the passenger ship so that the cabins can be, for example, balcony cabins with a sea view.
  • a multi-storey deck structure situated above the deck of the passenger ship so that the cabins can be, for example, balcony cabins with a sea view.
  • This intermediate space also contains the staircases and lifts.
  • One example of a passenger ship's deck structure provided with an intermediate space is presented in the document US 4838190 A .
  • the objective of the presented solution is to solve the above described problems or drawbacks.
  • a further advantage is that the air handling units are located in the intermediate space so that they do not take up space from passenger cabins on the sides of the ship, which may be provided with balconies and/or which have a sea view.
  • a further advantage is that the air handling units are adapted to restrictedly serve, for example, only the passenger cabins of two decks or at most three decks so that it is possible to choose into use air handling units, which are smaller than before.
  • This also provides the advantage of shorter ductworks for fresh air and exhaust air, because the air handling units are located closer to the passenger cabins than big state-of-the-art air handling units.
  • This also has the advantage that pressure losses in ductworks are smaller and needed components can be smaller or components with lower power.
  • a further advantage is that compact air handling units are utilised, requiring only a small floor area for installation.
  • the compact size is also achieved by connecting different ducts, such as supply duct and/or return duct, for example, on top of the air handling unit, in which case the air handling unit is of a vertical structure and, with its ducts, takes up space mainly in the vertical direction. This saves space compared to state-of-the-art apparatuses, the structure of which with ducts is long in the horizontal direction and which require a lot of floor area and space, for example, for purposes of service.
  • An advantage is that by means of one vertical ventilation shaft two or more air handling units on different floors can be brought close to the ventilation shaft commonly serving these air handling units.
  • ventilation shaft can be designed as an integrated part of the ship's steel structure, thus freeing space for other structures to be placed into the intermediate space.
  • Devices with a vertical structure known per se from above-ground buildings can be applied in the presented air-conditioning system for a passenger ship, especially in its air handling unit.
  • the structure and materials of these devices need only be adapted to meet the requirements of maritime conditions, for example, by using stainless materials.
  • FIGs 1 and 2 there is illustrated an example of a passenger ship 10, in which the air-conditioning system of the solution can be applied.
  • Figure 1 there is illustrated a cross-section of the passenger ship 10 along the line A - A of Figure 2.
  • Figure 2 illustrates a cross-section of the passenger ship 10 along the line B - B of Figure 1 .
  • the object is especially a cruise vessel designed for several hundreds or thousands of passengers.
  • the said passenger ship 10 comprises ahull 12, a deck 18 and a deck structure 20.
  • the hull 12 forms a waterproof, floating and load-bearing steel structure, inside which there may be located, for example, a power unit for the passenger ship, technical premises, crew cabins, car decks or premises common to the passengers.
  • the hull 12 defines a horizontal centreline X of the passenger ship, which joins with or is parallel to the longitudinal direction and the direction of travel of the passenger ship 10.
  • the hull 12 also defines a first side 14 and a second side 16 on both sides of the centreline X, on opposite sides of the centreline.
  • the hull 12 is principally covered by the horizontal deck 18, on top of which the overlying deck structure 20 of the passenger ship 10 is located.
  • the deck structure 20 consists of several superimposed floors 22, of which there may be, for example, at least 4 or 10 - 12.
  • the deck structure 20 may have several superimposed floors 22 with a similar structure and intended for passenger cabins 26.

  • the hull 12, the deck 18 and the deck structure 20 typically have a steel structure.
  • Each said floor 22 has a first group 24 of separate passenger cabins 26, which are located successively in the longitudinal direction of the passenger ship 10. There are, for example, at least 10 or 15 - 20 successive passenger cabins 26. These are located on the first side 14 of the hull 12.
  • Each said floor 22 further has a second group 28 of separate passenger cabins 26, which are located successively in the longitudinal direction of the passenger ship 10. There are, for example, at least 10 or 15 - 20 successive passenger cabins 26, or dozens of these. These are located on the second side 16 of the hull 12.
  • the said passenger cabins 26 are cabins that, for example, have a balcony and/or sea view.
  • the passenger cabins 26 are, for example, pre-furnished modules, which are installed into the deck structure 20 and connected to different systems of the passenger ship 10, such as electricity, water or ventilation systems.
  • the deck structure 20 further has an intermediate space 30, which is in a horizontal direction located on each floor 22 between the first and second passenger cabin groups 24, 28; for example, on the centreline X.
  • the intermediate space 30 extends in a vertical direction through several superimposed floors 22; for example, at least through four floors 22 or 10 - 12 floors 22. According to one example, the intermediate space 30 extends through all the floors 22 of the deck structure 20.
  • the intermediate space 30 extends in the longitudinal direction of the passenger ship 10 past several successive passenger cabins 26; for example, past at least 10 or 15 - 20 passenger cabins, or past all of them. According to one example, the intermediate space 30 extends to the whole length of the first and second passenger cabin groups 24, 28.
  • the intermediate space 30 is formed between the first and second passenger cabin groups 24, 28 on different floors 22.
  • the intermediate space 30 extends in the longitudinal direction of the passenger ship 10.
  • a corridor 50 which extends past the passenger cabins 26 in the longitudinal direction of the passenger ship 10 .
  • a steel bulkhead of the passenger ship 10 separates the intermediate space 30 and each corridor 50 on each floor, simultaneously limiting the intermediate space 30.
  • the intermediate space 30 may additionally include one or several stairways and lifts, which travel through several floors 22.
