Abstract: An air conditioning system for a nautical vehicle includes a main body including an assembly, and a blower including an inlet and an outlet, the inlet being in air communication with the main body, the blower further including blades rotating therewithin about a first axis, the assembly for adjusting the blower with respect to the main body about a second axis so as to alter an orientation of the outlet. The assembly includes a guiding cover and a cylindrical duct element for maintaining the main body and the blower in air communication with one another. The duct element has a first base and a second base, and is coupled to the blower at the second base. The first base of the duct element is dimensioned to correspondingly fit the guiding cover, and the duct element is rotatably adjustable around the guiding cover about the second axis at the first base.

Abstract: In a marine vessel (such as a yacht or other boat) in the range of 45-75 feet a chilled water air conditioning system is provided having a significant advantage over split central systems. Utilizing two-four water chilling modular units the chilled water capacity only needs to accommodate about 75-90% of the calculated BTU heat load for the vessel, while the air handlers are rated at about 100% of the calculated BTU heat load. Each modular unit has no refrigerant connection exterior of the casing containing all of its components, including a condenser coil, evaporator coil, compressor, reversing valve, and expansion tubing, all operatively connected to each other by refrigerant lines within the casing. Chilled water is circulated into and out of the evaporator coil by an exterior pump and expansion tank operatively connected to each of the modular units, the chilled water passing through a coil unit of an air handler.

Abstract: A marine air conditioner (which may also be used as a heat pump) has a low volume to cooling capacity ratio, and high efficiency. A blower is connected to a shroud, and within the shroud are a water cooled tube-in-tube condenser coil and a raised lance fin evaporator coil. The condenser coil is mounted between the evaporator coil and the blower so that air is drawn past the evaporator coil, then past the condenser coil, and then discharged by the blower. The shroud and blower are mounted, along with a rotary compressor connected to the coils by refrigerant lines, in a condensate drain pan having side walls of 1.5 inches or more in height and a plurality of widely spaced drain plugs or fittings. The cooling water inlet and outlet for the condenser coil pass through a wall of the shroud, and the inlet is connected to a water pump below the water line of the boat in which the condensate pan is mounted.
