Integrated air-conditioning station for naval vessels

Abstract

The invention discloses an integrated air-conditioning station for naval vessels, belongs to the field of air-conditioning refrigeration, and relates to a low-noise and integrated air-conditioning station using low-temperature fresh water as a refrigerant medium and used for a ventilation air-conditioning system. When the integrated air-conditioning station supplies air, the high-temperature and high-humidity air sequentially passes through a muffling air return opening, an air filter, an air heat exchanger, a dehydrator, an air conditioner fan and an air outlet plenum chamber to form the low-temperature and low humidity air to be supplied outside through an air outlet for ventilating and air conditioning. The muffling air return opening adopts a multi-layer grid structure with the surfacemade of rough and pitted sound absorption materials, and air noise is continuously attenuated through refraction, scattering and nonlinear propagation of sound. The integrated air conditioning station for the naval vessels is low in vibration noise, uniform in air supply and high in pressure head, and air supply static pressure and air supply uniformity are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and in particular relates to an integrated air-conditioning station for ships. Background technique [0002] There are various forms of air-conditioning devices in my country's shipbuilding industry. At present, coil-type air conditioners and split-type air conditioners are widely used. The refrigerant medium is divided into Freon refrigerant and fresh water. The integrated air-conditioning station involved in the present invention uses fresh water as the refrigerant medium. . At present, the internal space resources of small and medium-sized and compact ships are very limited, which puts forward higher requirements for equipment miniaturization. In addition, equipment with only a single function and equipment in a decentralized arrangement often have many, miscellaneous, and chaotic components, which have a very adverse impact on the daily use, management, personnel ma...

Problems solved by technology

Split air conditioners are mostly assembled, that is, the air supply, filtration, cooling, water removal and other components of the equipment are arranged separately. This type of air conditioner takes up a lot of space for installation, is not easy to maintain and disassemble, and the outer surface is easy to be polluted

[0004] In my country's existing shipbuilding industry, coil air conditioners and split air conditioners have the following limitations: (1) Coil air conditioners mostly adopt the air supply mode of bottom inlet and side outlet, the effective air supply distance is short, and the cooling capacity is low. Small, not suitable for ventilation and air conditioning in a large area

(2) The components of the split air conditioner are arranged in a scattered manner, occupying a lot of space resources, and it is inconvenient to use and manage; the air outlet usually adopts the form of a single air duct, and it is easy to cause uneven air volume distribution and The problem of insufficient wind pressure; the air-conditioning fan is directly exposed to the air as a power rotating machine, which is the main source of noise, and the noise is relatively loud during ventilation and air conditioning
