Air conditioner fresh air system

Abstract

The invention provides an air conditioner fresh air system which comprises a structural air duct located on a bow broadside, a structural air duct and a user air conditioner at the tail end. The structural air duct is sealed through a deck, a bulkhead and a broadside outer plate of a ship to form a relatively independent space communicated with outside air. An air collecting opening is formed in the position, corresponding to the structural air duct, of the broadside outer plate; the structural air duct is sealed by a deck and a bulkhead of a ship to form a relatively independent space communicated with the structural air duct, and the structural air duct is arranged perpendicular to a swell line of the ship. The structure of the ship body is simply changed, and necessary functional parts are arranged in the air collecting opening, the air groove and the air duct, so that the function of taking fresh air from the curved surface linear broadside outer plate of the air conditioner can be achieved, and the problem that a conventional shutter cannot be arranged on a curved surface plate of an air conditioner fresh air system to take fresh air is solved.

Description

Technical Field

[0001] The invention belongs to the technical field of ship design, and in particular relates to an air conditioning fresh air system. Background Art

[0002] Generally, the method for obtaining fresh air in a ship's air-conditioning system is to install a closable ventilator on the open deck or to install a closable shutter on one side of the open bulkhead, and then connect it to the fresh air inlet of the air conditioner through the air duct.

[0003] However, the existing fresh air acquisition methods have the following problems:

[0004] 1. Generally, the open-air deck is on the top of the superstructure, and the air-conditioning room is arranged at the bottom or inside of the superstructure. If fresh air is taken by setting a closable ventilator on the open-air deck, it is necessary to set up a very complex air duct to connect the air conditioner and the ventilator. There are certain requirements for the location of the air-conditioning room and the layout space of the air duct, which is quite restrictive and difficult to arrange.

[0005] 2. For passenger ships, scientific research vessels and other ships that have the air-conditioning room arranged at the bow, the bow side structure is often a curved surface, and it is impossible to set conventional shutters to bring fresh air to the air conditioner. Summary of the invention

[0006] In order to solve the technical problems existing in the prior art, the present invention provides an air conditioning fresh air system, comprising a structural air slot located on the bow side, a structural air duct and a user air conditioner at the end:

[0007] The structural wind trough is enclosed by the deck, bulkhead and side outer plate of the ship to form a relatively independent space connected to the outside air, and a wind outlet is opened at the position of the side outer plate corresponding to the structural wind trough;

[0008] The structural air duct is enclosed by the deck and bulkhead of the ship itself to form a relatively independent space communicated with the structural air trough, and the structural air trough is arranged perpendicular to the ship's swelling line.

[0009] Furthermore, the air intake is arranged at a position 2300 mm or more from the deck.

[0010] Furthermore, the air collection port is provided with a louver-type air guide plate, and the direction of the air guide plate is obliquely downward.

[0011] Furthermore, a vertical baffle is provided in the structural wind trough near the air collecting port, and the height of the baffle is greater than the opening position of the air collecting port.

[0012] Furthermore, a drainage outlet is provided at the bottom of the structural air duct.

[0013] Furthermore, a manhole cover is provided at the bottom of the structural air duct.

[0014] Furthermore, a stainless steel wire mesh is provided at the air duct opening where the structural air duct is connected to the structural air slot.

[0015] Furthermore, a set of shut-off dampers is also provided in the structural air duct.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention utilizes the structure of the hull itself to make simple changes. By setting necessary functional components in the air intake, wind slots and air ducts, the function of the air conditioner to take in fresh air on the curved linear side outer plate can be realized, thereby solving the problem that the air conditioning fresh air system cannot set conventional shutters on the curved panel to take in fresh air.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1-Figure 3 The air conditioning fresh air system provided by the present invention is mainly composed of a structural air trough located on the bow side, a structural air duct and a user air conditioner at the end. The structural air trough is simply closed by the ship's own deck, bulkhead, side outer plate, etc.; at a position 2300mm or more from the deck, an air outlet is mined on the side outer plate and a louvered wind guide plate is set, the wind guide plate is tilted downward, which can effectively prevent the outside water from flowing into the air trough; a vertical water / snow retaining plate is set near the air outlet, the height of which is greater than the opening position of the air outlet, and most of the rain / snow sucked in with the air can be blocked at the baffle and dripped to the bottom of the air trough instead of entering the air duct, and a drain outlet is set at the bottom of the air trough for drainage and a manhole cover is set for easy access and maintenance.

[0023] The structural air duct for fresh air of air conditioner is simply closed by using the deck and bulkhead of the ship itself, connected to the structural air slot, and stainless steel wire mesh is set at the opening of the air duct to prevent mosquitoes, mice, etc. from entering the air duct. The air conditioner is connected to the structural air duct with an air duct pipeline, and a set of shut-off dampers (electric or manual) are set on the pipe before entering the air conditioner, which can be used to close the air duct and isolate the air conditioner from the outside air.

[0024] In summary, the above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto. All equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification are within the scope covered by the patent of the present invention.
