Ship air conditioner

Abstract

The invention relates to a ship air conditioner which comprises an air conditioner box and a fresh air box, wherein a fresh air and return air mixing box, an air filter, an air heat exchanger, a water retaining device, a humidifier and an air sending fan are sequentially arranged in the air conditioner box, a return air port is arranged on the front surface of the fresh air and return air mixing box, a toxicity-filtering fresh air port is arranged at the upper end of the fresh air and return air mixing box, and the air sending fan is connected with an air outlet static pressure box; and a fresh air adjusting port, a fresh air dust filter and a dual-speed fan are sequentially arranged in the fresh air box from top to bottom, wherein an air outlet port of the dual-speed fan is communicated with the fresh air and return air mixing box in the air conditioner box. The ship air conditioner respectively controls the dual-speed fan used for fresh air inlet and the fresh air adjusting port to be in the opening state or the closing state through an electric control box and controls the toxicity-filtering fresh air port used for air inlet after toxicity-filtering to be in the opening state or the closing state according to air environment located by a ship, thereby immediately switching the different air inlet sources on the air conditioner box and the fresh air box, meeting the air regulation of the ship under the normal or accidental working conditions, having the advantages of strong applicability, good filtering effect and long service life and being applicable to the ships during voyage and wartime.

Description

technical field [0001] The invention relates to an air conditioner for a ship, in particular to an air conditioner for switching between different wind sources according to the surrounding environment of the ship. Background technique [0002] At present, ships are often equipped with an air conditioning system to adjust the air temperature and humidity in the cabin. The conventional air conditioning system is suitable for mixing fresh air and return air from the air conditioning area in the mixing box, and then sending it to each air conditioning cabin after being processed by the air heat exchanger. use. [0003] When the ship is in an area with severe air pollution or toxic gas, most air-conditioning systems without poison filtering devices will stop working. A few ships have air-conditioning systems with poison filtering devices, which can filter harmful components in the air to cope with emergencies. Air pollution or toxic gases are emitted, but the poison filter devic...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the ship’s air-conditioning system does not have a poison filtering device in the prior art, when it is in an area with severe air pollution or toxic gas, it cannot normally supply air to the ship or cannot filter harmful components, or the ship’s air-conditioning system is only equipped with a poison filtering device. The poison filter device is prone to failure after long-term use, and the poison filter device must be replaced frequently. The cost of use is high, and there are potential safety hazards. Fresh air intake avoids long-term use failure of the separate air intake system, long service life, low cost of use, and high safety performance of the marine air conditioner
