BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to marine air conditioner decontamination.
2. Description of the Related Art
Recreational boating is very popular. The U.S. Coast Guard has estimated that there are over 20 million recreational boats in the United States. Recreational boats are commonly used for fishing, water skiing, sailing and cruising. At least 10 percent of recreational boats include a cabin. Cabins typically include a bunk, a lavatory and a kitchen.
In general, the warmest place on a boat is inside the cabin. Heat is generated by solar radiation, conduction, appliances, people and pets. Many recreational boats are now manufactured with air conditioning systems. After market air conditioners are also widely available. Air conditioning units specifically designed for marine use are referred to as marine air conditioners. A marine air conditioner may be cooled with water from a lake, sea, ocean or other body of water. A typical marine air conditioner includes corrosion protection from salt water.
Marine air conditioners are manufactured in a variety of configurations and capacities. A self contained unit may include a compressor and an evaporator coil in a single package. A central unit may include a single compressor which feeds several remote evaporator coils, each located in a different room. Some larger recreational boats include multiple units working in tandem. Designed for creature comfort, modem marine air conditioners operate quietly and with high efficiency. Efficient evaporator coils generate condensation. In high humidity conditions, it is common that a marine air conditioner may produce more than 1 liter of condensation per hour.

DETAILED DESCRIPTION OF THE INVENTION
Throughout this description, the embodiments and examples shown should be considered as exemplars, rather than limitations on the apparatus and methods of the present invention.
Many of today's marine vehicles are equipped with heat, ventilation and air conditioning (HVAC) systems. One aspect of a modem HVAC system is the efficient control of air quality within the passenger cabin.
Efficiency is related to the amount of power required to perform HVAC functions, for example, heating, cooling, humidifying, dehumidifying, filtering and decontaminating air that is transferred to and from the passenger cabin. As efficiencies are improved, the operating costs of the HVAC system and in turn, the marine vehicle are reduced. Moreover, since less energy is required to power efficient HVAC systems, less fuel is burned, resulting in lower emissions.
Referring now to FIG. 1, there is shown a partial plan view of a cabin 100. The cabin 100 may be a small room on a marine vehicle providing private accommodations for one or more persons. The cabin 100 may be a compartment at least partially above and/or below deck for passengers or crew on a marine vehicle. A marine vehicle may be a boat, a yacht, a ship, a submersible, an amphibious vehicle or other vessel. The marine vehicle may include a hull.
The cabin 100 may include an HVAC system 105. The HVAC system may include a return air grille 130, an air conditioner 120, a duct 140 and a supply air grille 150. The HVAC system 105 may provide cooling and/or dehumidification to the air within the cabin 100 in order to make recreational boating more pleasurable.
The term grille refers to a covering which includes a barrier and an opening to control the passing of a fluid such as air to or from an HVAC system. A grille may include a grating, a slot, a slit, a hole, a screen or other design. A grille may include functional as well as aesthetic qualities. Air may enter the HVAC system 105 via the return air grille 130. The return air grille 130 may be disposed external to or within the cabin 100. The return air grille 130 may be located in an inconspicuous location, for example, underneath a cabinet 110, a dinette, a bed, a sofa, a berth, a helm station or other location. The return air grille 130 may be manufactured from a variety of materials, for example, metal, plastic, wood or other material. The dimensions of the return air grille 130 may be selected based on amount of air that the air conditioner 120 requires. The return air grille 130 may be 10′′ long by 10′′ high by 1⁄8′′ thick or other dimensions. The return air grille 130 may prevent large objects from passing into the HVAC system 105. If large objects pass into to the HVAC system 105, the HVAC system 105 may prematurely fail or run inefficiently.
An air conditioner is a device which modifies the heat and/or the moisture content of air. The air conditioner 120 may be powered electrically via a power generator (not shown), a vehicle's power system (not shown), an alternator (not shown), a hookup to dock power (not shown) or other power source. The air conditioner 120 may be hidden behind the return air grille 130. The air conditioner 120 may be located remote to the cabin 100. The air conditioner 120 may be disposed in a window (not shown) of the cabin. The air conditioner 120 may receive air which passes through the return air grille. The air conditioner 120 may remove heat and/or moisture from the air. The air conditioner 120 may supply the conditioned air to the cabin 100 via the duct 140 and the supply air grille 150. The air conditioner 130 may provide conditioned air directly into the cabin 100.
A duct is a pipe, tube or channel through which a fluid may pass. The duct 140 may be flexible, rigid and/or insulated. The duct 140 may be hidden within a wall 145, below the floor (not shown) or in the ceiling (not shown). The duct 140 may be disposed conspicuously within the cabin 100 or disposed in another location. Conditioned air may pass from the duct 140 through the supply air grille 150 into the cabin 100. The supply air grille may prevent large objects from passing into the HVAC system 105.
The supply air grille 150 may be disposed near the top of the cabin 100 as cooler conditioned air may fall through the cabin. The return air grill 150 may be integral to the air conditioner 130.
Referring now to FIG. 2, there is shown a perspective view of a marine air conditioning system 205. The marine air conditioning system 205 may include a return air grille 230, a marine air conditioner 200, a duct 240 and a supply air grille 250. The marine air conditioner 200 may be installed behind a wall 220 of a cabin 206. The marine air conditioner 230 may be installed in a hidden location to promote aesthetics within the cabin 206. The wall 200 may be any wall of the cabin 206. The marine air conditioner 200 may be disposed on a floor 210. The floor 210 may be the floor of the cabin 206, a pedestal of the cabin 206, or any other horizontal surface within the cabin 206. The marine air conditioner 200 may be attached to or mounted to the floor 210. The marine air conditioner 200 may be affixed to a wall (not shown) via brackets (not shown), straps (not shown), a shelf (not shown) or other support. The marine air conditioner 200 may be disposed at a distance behind the return air grille 230. For example, the marine air conditioner 200 may be 3′′, 12′′, 20′′ or other distance behind the return air grille 230. The distance between the marine air conditioner 200 and the return air grille 230 may be based on the spatial constraints inside the cabin and behind the wall 220.
Referring now to FIG. 3, there is shown a plan view of a marine air conditioner 300. For example purposes, the marine air conditioner 300 shown in FIG. 3 is a self contained unit. Self contained units are popular in recreational marine vehicles having a length of 18-50 feet because they are inexpensive, small, compact and are easy to install. A self contained unit may have a volume of approximately 1 cubic foot or other volume. A typical self contained unit may have a width of 8′′ or other dimension, a height of 113⁄8′′ or other dimension, and a length of 16′′ or other dimension. The marine air conditioner 300 may include an evaporator coil 310, a shroud 320, a drain pan 330, a compressor 350, a condenser (not shown), power supply 340 and a blower 360.
The evaporator coil 310 may function as a heat exchanger. The transfer of heat from air to the evaporator coil 310 is related to the surface area of the evaporator coil 310. Heat may be transferred through the surface of the evaporator coil 310. Typically, an evaporator coil includes a series of refrigerant tubes integrated with fins. The evaporator coil 310 may be constructed of aluminum, copper or other material which readily transfers heat. The evaporator coil 310 may have dimensions of 8′′×8′′×2′′, 10′′×12′′×3′′, 8′′×11 ′′×4′′ or other dimensions.
The fins (not shown) of the evaporator coil 310 help maximize the surface area of the evaporator coil. Refrigerant may pass through the refrigerant tubes of the evaporator coil 310, expand and cool. Heat may be transferred from the air passing over the evaporator coil 310 through the surface of the evaporator coil 310 to the refrigerant. As heat is removed from the air passing over the evaporator coil 310, condensation may form on the surface of the evaporator coil 310.
The evaporator coil 310 may be disposed above the drain pan 330. The evaporator coil 310 may be mounted to, attached to or integral with the drain pan 330. The evaporator coil 310 may be at least partially enclosed by the shroud 320.
The condenser (not shown) may be disposed within the shroud 320 and behind the evaporator coil 310. The condenser may be disposed remote from the evaporator coil 310. The condenser may receive the heated refrigerant from the evaporator coil 310. The condenser may function as a heat exchanger wherein seawater is pumped through the condenser and heat is transferred from the refrigerant through the condenser and to the seawater. The heated seawater may then be returned to a body of water such as a sea, ocean, harbor, marina, lake or other body of water. The condenser may be mounted to, attached to or integral with the drain pan 330 and/or the shroud 320.
The blower 360 may include an enclosure (not shown) and a fan (not shown). The enclosure may be attached to, mounted to or integral with the drain pan 330 and/or the shroud 320. The blower 360 may receive air after it passes over the evaporator coil 310 and/or the condenser (not shown) and force the air into a duct (not shown) or into a cabin (not shown).
A shroud is a surface that covers, screens or guards a device. The shroud 320 may partially enclose and/or protect the evaporator coil 310 and/or the condenser (not shown). The shroud 320 may be attached to the evaporator coil 310 and/or to the drain pan 330. The shroud 320 may be manufactured from a metal, composite or other material. The shroud 320 may be rigid. The shroud 320 may function as a duct for the air to pass through from the evaporator coil 310 to the condenser (not shown) to the blower 360.
The shroud 320 may have a geometry based on the geometry of the evaporator coil 310, the condenser (not shown) and the blower 360. The geometry of the shroud 320 may include rectangular or other shaped sections (not shown) that surround the upper surface (not shown) and the side surfaces (not shown) of the evaporator coil 310. The geometry of the shroud 320 may include a tapered section enclosing the condenser (not shown) between the rectangular sections (not shown) and the blower 360. The geometry of the shroud 320 between the evaporator coil 320 and the blower 360 may include regular shapes, irregular shapes, steps, tapers and/or other geometries.
The compressor 350 is a motor which compresses a fluid. Typically, a compressor of an air conditioner will compress a refrigerant after it exits the condenser and before it enters the evaporator coil. The compressor 350 may be mounted, attached to or integral with the drain pan 330. The compressor 350 may be located remote from the evaporator coil 310.
A power supply is an electronic device or system that converts electric power from a form being received to a form which is supplied to a load. A power supply may include an enclosure and electronics housed within the enclosure. A power supply may convert power from DC to AC, from DC to DC, or from AC to DC, or other. A power supply may regulate electric power. The enclosure may protect the power supply. The power supply 340 may be attached to, mounted to or integral with the drain pan 330. The power supply 340 may receive power from a generator (not shown), an alternator (not shown) attached to the engine (not shown) of the marine vehicle (not shown), a dock power source or another power source. The power supply 340 may provide power to the compressor 350 and the blower 360.
The term drain pan refers to an open receptacle into which water may collect and be drained from. The drain pan 330 may provide a structural base to the compressor 350, the power supply 340, the evaporator coil 310, the shroud 320 and the blower 360. The drain pan 330 may be constructed of metal, composite or other material. The drain pan 330 may be disposed below the evaporator coil 310, the shroud 320 and the power supply 340. The drain pan 330 may be deep, for example 2′′ or other dimension. The drain pan 330 may have dimensions based on the dimensions of the marine air conditioner 300. For example, the drain pan may have a width of 8′′ or other dimension and a length of 16′′ or other dimension. The drain pan 330 may include one or more drain holes (not shown) connected to drain tubes (not shown). The drain pan 330 may receive condensation that drips down from the evaporator coil 310 and/or the condenser (not shown).
Due to factors such as condensation and humidity, some moisture may remain on the evaporator coil 310 and in the drain pan 330 for an extended duration. It is common for bacteria, viruses, molds, microbes and other microorganisms to grow on moist surfaces. When the evaporator coil 310 accumulates undesirable substances on its surface, it will not function at optimum efficiency because its effective surface area for heat transfer will be reduced. Undesirable substances refer to any of mold, bacteria, fungi, viruses, mildew, allergens, spores, yeasts, mycotoxins, and endotoxins.
Referring now to FIG. 4, there is shown a plan view of a marine air conditioning system 400. The marine air conditioner 400 may include an evaporator coil 410, a shroud 420, a first power supply 480, a drain pan 425, a bracket 430, an electric discharge lamp 450, a clasp 460, a second power supply 470 and wires 490.
The term electric discharge lamp refers to an apparatus which emits radiation caused by an electric discharge from electrodes in an enclosure. An electric discharge is electrical conduction through a gas or vapor in an applied electric field. An enclosure is a hollow device used to hold vaporizable materials and gases. An enclosure may be at least partially translucent. An enclosure may be constructed of glass, metal, quartz, or plastic. Electric discharge lamps may be fluorescent lamps, mercury vapor lamps, low pressure sodium lamps and high pressure sodium lamps.
The electric discharge lamp 450 may be shaped toroidal, u-shaped, cylindrical, bulbous or other shape. The electric discharge lamp 450 may have a cross sectional shape of a circle, an oval, a tetrahedron, a pentagon, a hexagon, an octagon or other shape. Common cylindrical electric discharge lamps are manufactured in lengths of approximately 16′′, 22′′, 28′′, 34′′, 40′′ and other lengths. The dimensions of the electric discharge lamp 450 may be based on the dimensions of the evaporator coil 450.
The electric discharge lamp 450 may include a vaporizable material, such as mercury. The mercury, when electrically excited, may emit ultraviolet light at a germicidal wavelength. A germicidal wavelength may be at an ultraviolet-C (UVC) wavelength. A germicidal wavelength, for example 254 nm, is a wavelength of light which retards buildup or accumulation of undesirable substances. UVC may also kill undesirable substances.
The term germicidal lamp refers to a device which emits light at a germicidal wavelength. Examples of germicidal lamps include electric discharge lamps and solid state devices. Solid state devices include light emitting diodes. Some deep ultraviolet light emitting diodes may emit light at a wavelength between 250 nm and 290 nm with a peak of 254 nm or other wavelengths. Deep ultraviolet light emitting diodes may be disposed in an array, for example a 4×4 array, a 10×10 array or other configuration.
A bracket is a structural device which mounts one device in a fixed position relative to another surface. Typically, a bracket may support a vertical load, have two sections that are disposed at an angle to one another. A bracket may serve as a brace, a cantilever, or a support for a shelf or other surface or device. The bracket 430 may include a first section 475 and a second section 476. The first section 475 may be attached to, mounted to or integral with the shroud 420. If the bracket 430 is integral with the shroud 420, the bracket may be referred to as a flange. The first section 475 may be attached to a vertical surface 422 of the shroud 420 or a horizontal surface 421 of the shroud 420. The bracket 430 may receive mechanical support from the shroud 420.
The marine air conditioner system 400 may include a dampener (not shown) abutting both the first section 475 of the bracket 430 and the shroud 420. The dampener may vibration and/or shock from effecting the electric discharge lamp 450. The dampener may be a dampening sheet, a cushion pad, a bushing, a grommet, a washer, a spring, a shock, a bumper, a foam tape, a gasket, a dampening tape or other dampener. Vibration and/or shock have a tendency to cause the electric discharge lamp 450 to prematurely fail. By reducing the amount of vibration and shock transmitted to the electric discharge lamp 450, the life of the electric discharge lamp 450 may be preserved. Thus, maintenance costs associated with replacing the electric discharge lamp 450 may be reduced.
The first section 475 may be attached to the shroud 420 via a fastener 440, a clamp (not shown), a brazing (not shown), an adhesive (not shown) or a magnet (not shown). When the first section 475 is attached to the shroud, the first section 475 may be disposed in the same plane or parallel to a surface of the shroud 420 to which the first section 475 is attached. The first section 475 may have dimensions of an 11′′ height, an 8′′ depth and a 1/32′′ thickness or other dimensions.
The height of the first section 475 may be based on the dimensions of vertical surface 422 of the shroud 420. For example, the height of the first section 475 may be approximately 1⁄2 of the height of the vertical surface 422 of the shroud or other ratio. The height of the first section 475 may be based on the dimensions of another surface to which the first section 475 is attached, for example the power supply 480 or the drain pan 425.
The depth of the first section 475 may be based on the distance between the return air grille (not shown) and the marine air conditioner 400, the depth of the vertical surface 422 of the shroud 420 or another surface to which the first section 475 is attached. For example, if the distance between the return air grille (not shown) and the marine air conditioner is 20′′, the depth of the first section 475 may be 12.8′′ or other dimension.
The first section 475 may have dimensions of a square, rectangle, rhombus, trapezoid or other shape. The first section 475 may have a geometry based on the dimensions of the second power supply 470 in order to provide mechanical support to the second power supply 470. The bracket 430 may comprise a rigid material, for example a metal or a composite. The bracket 430 may comprise a material reflective of UVC, for example aluminum, steel or another material.
The second section 476 may be disposed at a 90° or other angle to the first section 475. When the first section 475 is attached to the shroud 420, the second section 476 may be offset relative to the evaporator coil 410. The second section 476 may be parallel to the length of the evaporator coil 410. The second section 476 may be substantially flat, curved, or bent in multiple sections along the length of the second section 476. The second section 476 may include a concave surface (not shown) facing the evaporator coil 410. A bent, curved or concave surface may allow radiation to be reflected from the electric discharge lamp 450 to the surface of the evaporator coil 410. The first section 475 and/or the second section 476 may provide mechanical support to the electric discharge lamp 450. The second section 476 may have dimensions of 11′′×4′′× 1/32′′ or other dimensions. The second section 476 may have a height based on the diameter of the electric discharge lamp 450. For example, the height of the second section 476 may be two or three times the diameter of the electric discharge lamp 450 or other ratio. If the second section 476 has height of two or three times the diameter of the electric discharge lamp 450, the second section 476 may reflect UVC radiation from the electric discharge lamp 450 towards the evaporator coil 410. The height of the second section 476 may be sufficiently small so that air flow is not greatly obstructed to the evaporator coil 410.
The bracket 430 may fix the electric discharge lamp 450 relative to the evaporator coil 410. The electric discharge lamp 450 may be secured relative to the second section 476 of bracket 430 via a clasp 460. The electric discharge lamp 450 may be secured relative to the first section 475 of the bracket 430 via a recessed mount (not shown). The electric discharge lamp 450 may be disposed substantially parallel to the length of the evaporator coil 410. The electric discharge lamp 450 may be disposed at an angle relative to the evaporator coil 410. The electric discharge lamp 450 may be disposed substantially perpendicular to the length of the evaporator coil 410. If the electric discharge lamp 450 is disposed substantially perpendicular to the length of the evaporator coil 410, the UVC radiation emitted from the electric discharge lamp 450 may reflect off the fins (not shown) and strike all or the majority of the surfaces of the evaporator coil 410. The electric discharge lamp 450 may be offset from the evaporator coil 410 by 3′′, 8′′, 12.8′′ or other dimension. The electric discharge lamp 450 may be offset from the evaporator coil 410 by a distance approximately 80% of the length of the electric discharge lamp 450. The electric discharge lamp 450 may be offset from the evaporator coil 410 by a distance approximately 25%-75% of the height of the evaporator coil 410. For example, if the height of the evaporator coil 410 is 12′′, the electric discharge lamp 450 may be offset from the evaporator coil 410 by 3′′, 6′′, 9′′ or other dimension. By offsetting the electric discharge lamp 450 from the evaporator coil 410 by a distance approximately 25%-75% of the height of the evaporator coil 410, uniform distribution of UVC may be emitted towards the evaporator coil 410.
The clasp 460 may provide mechanical support to the electric discharge lamp 450. The clasp 460 may affix to the bracket 430 via a fastener, a welding, a magnet, or an adhesive. The clasp 460 may be integral to the bracket 430. The clasp 460 may be one of or combinations of a spring clamp, a clamp, a sleeve, a hanger, a race, a locking clamp, a clip, a holster, and a strap. The clasp 460 may include subassemblies comprising a metal, plastic, composite or other material. The clasp 460 may include fasteners. The clasp 460 may at least partially surround a circumference of the electric discharge lamp 450. The clasp 460 may comprise a material that is resistant to heat and environmental elements. An example of the clasp 460 is a stamped aluminum spring clip with a hard plastic coating. The clasp 460 may secure the electric discharge lamp 450 in relation to the bracket 430. The marine air conditioning system 400 may include a dampener (not shown) abutting both the electric discharge lamp 450 and the clasp 460. The dampener (not shown) may reduce vibration and shock from effecting the electric discharge lamp 450.
The second power supply 470 may provide power to the electric discharge lamp 450 via wires 495 and a socket 496. The second power supply 470 may be electrically connected to the first power supply 480 or another power source via plural wires 490. The second power supply 470 may be mounted or attached to the bracket 470. The second power supply 470 may be located remote from the bracket 470. The second power supply 470 may be or include a ballast. A ballast is a power converter that regulates electric power and functions as a starting and control unit for an electric discharge device. The ballast initially provides a voltage to ionize the gas or vaporizable material in the tube. The ballast then controls the power that drives the electric discharge lamp 450. The second power supply 470 may be integral to the electric discharge lamp 450.
When the marine air conditioning system 400 is installed and operating, the electric discharge lamp 450 may emit UVC radiation towards the evaporator coil 410 and/or to a drain pan 425. The electric discharge lamp 450 may emit UVC omnidirectionally. The electric discharge lamp 450 may emit UVC directly towards the second section 476 of the bracket 470, which in turn may reflect the UVC towards the evaporator coil 410. The electric discharge lamp 450 may emit UVC at a wavelength substantially at 253.7 nm towards a surface of the evaporator coil 410 and/or the drain pan 425 while generating an insignificant quantity or less of ozone. The electric discharge lamp 450 may be disposed upstream of the evaporator coil 410 such that the minimum photon energy striking the surface of the evaporator coil 410 is at least 430 μW/cm2.
By emitting UVC towards the evaporator coil 410, undesirable substances may be reduced from the surface of the evaporator coil 410, maximizing the surface area of the evaporator coil 410. Because efficiency of the marine air conditioning system 400 is related to the surface area of the evaporator coil 410, the UVC radiation may cause the marine air conditioning system 400 to consume less energy. Typically, maintenance of evaporator coils require chemical cleaning when undesirable substances build up on the evaporator coils. If undesirable substances are reduced from the surface of the evaporator coil 410 via UVC radiation, the evaporator coil 410 may not require chemical cleaning as frequently. Thus, maintenance costs may be reduced. Moreover, the electric discharge lamp 450 may at least partially sterilize the air provided to the cabin. If the electric discharge lamp 450 at least partially sterilizes the air provided by the marine air conditioning system 400, the indoor air quality (IAQ) of the cabin may be improved.
Referring now to FIG. 5, there is shown an elevated view of the marine air conditioning system of FIG. 4. The electric discharge lamp 450 may be disposed upstream of evaporator coil 410. The electric discharge lamp 150 may be disposed between the return air grille 495 and the evaporator coil 410.
