Return air purification system of ship air conditioner

Abstract

The invention discloses a return air purification system of a ship air conditioner, which comprises a central air conditioner, an air purification device, a return fan, a return air cavity and a return air inlet, the return air cavity is a sealed cavity formed between an inner ceiling of a cabin and a ship deck, and the return air inlet communicated with the inner space of the cabin is formed in the inner ceiling of the cabin, the air return cavity is communicated with an air inlet of the air return fan through a first air return pipe, an air outlet of the air return fan is communicated with an air return opening of the central air conditioner through a second air return pipe, a silencer is connected to the position, close to the air return cavity, of the first air return pipe, and an air purification device is connected to the second air return pipe. Air in the cabin can be effectively filtered and sterilized, high-quality and efficient clean air is provided for the cabin, and meanwhile noise of a ship air conditioner can be lowered.

Description

technical field [0001] The invention relates to the technical field of ship air conditioners, in particular to a return air purification system for ship air conditioners. Background technique [0002] Due to the harsh surrounding environment, ships and offshore operating platforms are usually equipped with closed equipment, so that the fresh air in the ship's warehouse cannot be fully exchanged with the outside world, and because of the long-term coexistence of personnel and equipment in the ship's warehouse, there are peculiar smells and volatile harmful substances in the air. Pollutants such as gas and bacteria stay in the ship's cabin for a long time, directly threatening the health of the crew. [0003] At present, the air-conditioning system of ships only has simple filtering equipment, which only has a certain effect on the treatment of large suspended particles in the air, but it is not obvious at all for cabins with dense personnel and a large number of circulating b...

[0002] Due to the harsh surrounding environment, ships and offshore operating platforms are usually equipped with closed equipment, so that the fresh air in the ship's warehouse cannot be fully exchanged with the outside world, and because of the long-term coexistence of personnel and equipment in the ship's warehouse, there are peculiar smells and volatile harmful substances in the air. Pollutants such as gas and bacteria, which stay in the ship's cabin for a long time, directly threaten the health of the crew

[0003] At present, the air-conditioning system of ships only has simple filtering equipment, which only has a certain effect on the treatment of large suspended particles in the air, but it is not obvious at all for cabins with dense personnel and a large number of circulating bacteria, viruses, and harmful gases in the air. In order to improve the air quality in the cabin, in the prior art, the frequency of air-conditioning ventilation is increased to increase the amount of fresh air in the cabin to dilute the pollutants in the air. This method increases the load of the air conditioner. and electrical loads, wasting limited energy on board
