Abstract

The invention provides a closed mast internal air-conditioning system for naval ships. The system includes an integrated cooling main unit, a local cooling unit, a liquid dividing valve set, a return collector, an electronic expansion valve and the like, As that cool demand of the cabin is realized, At that same time, a local cool unit is arranged on the upper part of the electronic cabinet to cool the upper area of the electronic cabinet, which can realize the combined cooling of refrigerant refrigeration and mechanical refrigeration with seawater direct cooling, A refrigeration device cansimultaneously control the working environment in the enclosed mast and the upper working environment of the electronic equipment, To realize the integrated cooling mode of seawater and conventional mechanical refrigeration for enclosed mast and electronic cabinet, the whole application system is energy-saving, environmentally friendly, safe and reliable, and has high application value for the design of enclosed mast air-conditioning system.

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...
