Ship cabin rain falling type air supply and return system and ship

Abstract

The invention belongs to the field of ship ventilation and interior decoration, and provides a ship cabin rain-down type air supply and return system and a ship, and the system comprises a static pressure silencing box which is arranged below a deck of a ship cabin and is communicated with an air supply pipeline of the ship cabin; a first rain down ceiling which is arranged on the bottom face of the static pressure silencing box, and a first gap with the void ratio determined based on the air supply amount of the air conditioner is formed in the first rain down ceiling; and a second rain descending ceiling which communicates with an air return pipeline of the ship cabin, and a second gap with the void ratio determined based on the air return amount of the air conditioner is formed in the second rain descending ceiling; return air passes through the second rain down ceiling and then is sent back to the return air pipeline through the outside of the static pressure box silencing box. The air outlet area of the air conditioner is increased, air outlet of the air conditioner is uniform, the temperature field is good, and the air speed is reduced, so that noise reduction is achieved, and the comfort and experience of personnel in a cabin are improved; a grid does not need to be additionally arranged on a cabin door to serve as an air return opening, and privacy of personnel in a cabin is protected.

Description

technical field [0001] The invention belongs to the technical field of ship cabin ventilation and interior decoration, in particular to a ship cabin rain-drop air supply and return system and a ship. Background technique [0002] In order to provide a comfortable living environment for the crew or passengers on the ship, a balance of air-conditioning and fresh air needs to be achieved in the cabin: that is, the fresh air is sent into the cabin through the air conditioner on the ceiling, and a part of the air in the cabin also passes through the ceiling. The air conditioner returns to the outside of the cabin to achieve the balance of air volume and realize the circulation of air. How to set up a reasonable air supply and return path in the cabin without affecting the comfort of the cabin is a problem worth studying. [0003] As far as the existing cabin air supply path is concerned, the general ship is to install the air distributor on the ceiling and supply air through the...

Problems solved by technology

[0003] As far as the existing cabin air supply path is concerned, the general ship is to install the air distributor on the ceiling and supply air through the outlet of the air distributor; as far as the existing cabin return air path is concerned, it is generally through the cabin door However, as customers (ship owners, especially mid-to-high-end passenger ships) and passengers continue to increase their living environment requirements, this approach is becoming more and more unsatisfactory

Although this method is simple, its disadvantages are: 1. The air outlets are concentrated, the air is not uniform, the temperature difference inside the room is large in a short period of time, and the comfort is poor; 2. The air distributor protrudes from the ceiling, which reduces the net height and reduces Unsightly; 3. The noise at the air outlet of the air distributor is relatively loud; 4. The ventilation grille is set on the door of the cabin, and the appearance is not beautiful; 5. Since the ventilation grid on the cabin door cannot be well The environment cannot achieve high privacy
