Air Conditioning System in Closed Mast of Ship

Abstract

The invention provides a closed mast air-conditioning system for a ship, which is composed of a comprehensive cooling main engine, a local cooling unit, a liquid separation valve group, a return collector, an electronic expansion valve, etc., which not only realizes the cooling demand of the cabin At the same time, the upper area of ​​the electronic cabinet is cooled by setting a local cooling unit on the upper part of the electronic cabinet, which can realize the joint cooling of direct cooling of seawater refrigerant refrigeration or mechanical refrigeration, and realize that one refrigeration device can control the working environment in the closed mast and the upper part of the electronic equipment at the same time The working environment realizes the comprehensive cooling mode of seawater and conventional mechanical refrigeration on the upper part of the closed mast and the electronic cabinet. The entire application system is energy-saving, environmentally friendly, safe and reliable, and has high application value for the design of the air-conditioning system in the closed mast of the ship.

Description

technical field [0001] The invention relates to an air-conditioning system for a ship, in particular to a closed mast air-conditioning system which is arranged with a large number of electronic cabinets and requires local cooling. Background technique [0002] Due to the combat and use needs of modern ships, a large number of electronic equipment, such as electronic cabinets and communication and navigation cabinets, are concentrated in the new closed mast, resulting in a large amount of heat. If the heat is not dissipated in time, it will cause the circuit and Overheating of equipment reduces efficiency. At present, the temperature control of the closed mast used in my country's ships is to rely on the special vertical cabinet air conditioner in the machine room for circulating ventilation and cooling. Due to the limited space in the closed mast, this air conditioning ventilation method can only improve the average temperature in the closed mast. For the upper area of ​​som...

Problems solved by technology

[0002] Due to the combat and use needs of modern ships, a large number of electronic equipment, such as electronic cabinets and communication and navigation cabinets, are concentrated in the new closed mast, resulting in a large amount of heat. If the heat is not dissipated in time, it will cause the circuit and Efficiency drops due to overheating of equipment

At present, the temperature control of the closed mast used in my country's ships relies on the special vertical cabinet air conditioner for circulating ventilation and cooling in the machine room. Due to the limited space in the closed mast, this air conditioning ventilation method can only improve the average temperature in the closed mast. For the upper area of ​​some electronic cabinets The temperature still cannot be effectively lowered. If the air pipe is used to separately cool the upper part of the cabinet, it will cause condensation in the electronic cabinet, which will seriously affect the safety and reliability of the equipment. In addition, the space requirements are not allowed. It can be seen that the traditional ship air conditioning system It cannot meet the design requirements of compactness and light weight of the closed mast
