Description

Marine air conditioner capable of preventing condensation The present invention relates to a marine air conditioner capable of preventing condensation, and more specifically, to a marine air conditioner capable of preventing condensation on the outside of a condensate drain pipe of an air conditioner installed in a ship or offshore structure. Generally, an air conditioning system is a device that cools, heats, and ventilates an indoor space through the phase change phenomenon of a refrigerant using an outdoor unit installed on the outdoor side, and is used as air conditioning equipment for general buildings and ships. Air conditioning systems installed in ship cabins vary depending on specifications, but centralized air conditioners or integrated or split-type air conditioners are used. A central air conditioning system installs an air conditioner on one side of the ship's exterior and supplies cold or hot air into the cabins through this air conditioner to provide heating and cooling within the cabins. When the air conditioner operates for cooling, the temperature of the air passing through the cooling coil drops and turns into saturated humid air; moisture exceeding the saturated humidity corresponding to that temperature turns into condense, forms on the coil, collects at the bottom of the coil, and is discharged to the outside of the equipment. The temperature of the condensate generated in the coil drops to a temperature corresponding to the surface temperature of the coil, and since the drain pipe through which the low-temperature condensate is discharged uses metal piping due to the characteristics of ships requiring non-combustible materials, the drain pipe itself easily becomes low-temperature and condenses moisture from the outside air, causing a large amount of condensate to form on the outer surface of the drain pipe. Unlike on land, high humidity at sea leads to significant condensation. Furthermore, as air conditioners are often not positioned on the lowest floor, condensate (dew) generated outside the drain pipes falls onto the ceilings, floors, or upper surfaces of lower floors. This causes equipment damage, such as electrical short circuits and corrosion, as well as safety issues like slipping on the floor and hygiene and aesthetic problems such as mold growth and the adhesion of foreign substances.
