The following information was gathered off the Internet to provide some planning data for possible installation of air conditioning and reverse cycle heating for a 45’ cruising sailboat owned by my friends Bev and Colin in Queensland who are having a new babe aboard. They might be of interest to the Kelly-Peterson Group as well. Of those looked at I think Arctic Marine Air, Flagship Marine and Marine Air Systems are the most promising. (Note. This article was written some time ago and many of the products and links may have changed. We chose not to put any airconditioning in our boat Some of this information may prove useful to those who are contemplating a cooled vessel)

HOW TO PROPERLY SIZE YOUR BOAT

by Flagship Marine, Inc.

Properly sizing your boat is a critical part of planning a successful air conditioning system that you will enjoy for many years.

Air conditioning systems remove the humidity from the air before you really see a significant drop in temperature, therefore, if you undersize your load significantly, you will be very uncomfortable and unhappy with your system when you need it the most!

Significantly oversizing the system will create "short cycling," not giving the system proper run time to satisfactorily dehumidify the vessel.

The general rule of thumb for sizing a pleasure boat is using the formula of 14 BTU's/cubic foot of air conditioned space. This factor is for normally constructed pleasure boats, and should be adjusted if non standard construction techniques are used.

For Average Below Deck Area in 44’ boat (for our KP44, would be a bit more for Cal46).
Length x Width x Average Height x 14 BTU

28 x 10 x 5 x 14 = 19,600 BTU (2 cabin + main cabin)

10 x 8 x 6 x 14 = 6,720 BTU (1 cabin)

CABIN	CUBIC FEET	BTU @ 12/ft^3	BTU @ 14/ft^3	BTU @ 19/ft^3
Forepeak Cabin	150	1,800	2,100	2,850
Main Saloon	625	7,500	8,750	11,875
Aft Cabin	450	5,400	6,300	8,550
Total Boat	1,225	14,700	17,150	23,275

To Determine Generator Size
use this equation
Amps x Volts x 2 = Generator Watts Required

It is prudent to use a factor of 16 to 19 BTU's/cubic foot for areas that are used during the heat of the day that have a lot of sunlight coming in, for example a pilothouse, especially if the roof is not shaded or well insulated.

For areas below deck that are primarily used after sunset, such as a stateroom, you can usually drop this factor to 11 or 12 BTU's/cubic foot.

Using these factors, combined with some common sense, will almost always produce a satisfactory system, however, you can always hire a professional to prepare a thermodynamic heat load analysis for your particular vessel.

Equally important to properly sizing the vessel is determining how much individual control is desired. For example, in individual staterooms you may wish to have small separate systems that are independently controlled and one large system for the main salon and galley areas.

The Carry-On fits in any standard-size hatch. The adjustable, waterproof cloth hood fits over the unit and the hatchcover, sealing in the cool air and keeping out insects and rain. There's an adjustable leg and a convenient bubble sight glass on the outside of the unit making it easy to level. And when you leave the dock, the Carry-On stows below deck, in your dockside locker or in the trunk of you car.

All operator controls are easily accessible on the bottom of the unit. You can turn it off and on, set the thermostat and adjust the fan speed from the cabin.

The Carry-On runs on normal dockside 115V, 60 Hz power. (A 230V, 50 Hz model is also available for areas outside North America.) It only draws 6 amps running. All internal components are made of corrosion-resistant material, and the outside case is built of tough, durable polymer. The best news is, the Carry-On is priced for budget-minded boatowners.

Installation Guidelines for Vector Compact
When choosing the proper model Vector Compact self-contained unit, primary consideration should be given to calculated BTU loads and available power supply. Special consideration should be given in determining the reverse cycle heating capacities under anticipated conditions. Reverse cycle operations affected by the seawater temperature. As it decreases, the units heat transfer capacity also decreases and proportionately affects the output of warm air. It is not recommended that the unit be operated in the heat cycle with water temperatures below 40 degrees Farenheight. The location of the Vector Compact self-contained unit should be dry and accessible for service. Placement of the unit should be adjacent to a low return air access from the area to be conditioned. The unit should be installed with the proper fasteners and secured to horizontal surface sufficient for the unit weight and torsional load from the vessel's movement. Never install your air conditioner air handler in bilge or engine room areas. Insure that the selected location is sealed from direct access to bilge and/or engine room vapors. Do not terminate condensate drain lines within four (4) feet of any outlet of engine or generator exhaust systems, nor in a compartment housing an engine or generator, nor in a bilge (vapors can travel up the drain line), unless the drain is connected properly to a sealed condensate or shower sump pump. Failure to comply may allow bilge or engine room vapors to mix with the air conditioners return air and contaminate living areas.	Grilles should be sized according to Marine Air design standards. Install the return air grilles low and supply air grilles high. Return air grilles must have removable filters installed on the unit. Ducting should be sized according to unit specifications. All ducting should be installed to be as smooth, straight and taut as possible, avoiding any unnecessary bends or loops. Once ducting runs are positioned properly they should be securely fastened to avoid shifting due to motion of the vessel. Plastic vacuum-formed and insulated aluminum transition boxes are available for proper air flow direction into any cabin area. Ducting should be properly secured to these transition boxes to prevent air flow leakage. Built-in plenums of chases must be sized properly, completely sealed and insulated. Reinforced marine grade hose must be used for the seawater circuit. All fittings must be double hose clamped. The hose should be routed upward from the thru-hull intake, sea cock, strainer and pump, to the condensing unit to prevent air locks in the centrifugal sea water pump. Circuit breakers and wire gauge must be sized according to marine design standards. Only standards tinned copper wire should be used. All equipment should be properly grounded. In keeping with regulations set forth by the EPA, only certified technicians should perform service on, or make adjustments to, the refrigerant circuit.

In the interest of product improvement, Marine Air Systems' specifications and design as outlined herein are subject to change without prior notice.

Installation Guidelines for Cool Mate
When choosing the proper model Cool Mate, primary consideration should be given to calculated BTU loads and available power supply. The 5K unit is ideal for use with either a shore power hook-up or a battery powered inverter which allows for underway air conditioning without the necessity of a generator. The 5K unit is available in 115V/60Hz (CLM5K) and 220V/50Hz (CLM5KZ). For 230V/60Hz applications a step down transformer must be used with the 115V 5K Cool Mate. This transformer weighs 19 pounds and is readily available in both 115V & 230V but are not recommended for use with an inverter. The location of the Cool Mate unit should be dry and accessible for service. The only air access should be from the return air source-never from the bilges, engine room or other combustible vapor source. Avoid odoriferous air sources, i.e. heads, holding tanks, etc. The unit should be installed with the proper fasteners and secured to a horizontal surface sufficient for the unit weight and torsion load from the vessel's movement. Grilles should be sized according to Marine Air Systems design standards (refer to Supply and Return Air Grilles literature sheet). Install the return air grilles low and supply air grilles high. Ducting should be sized according to unit specifications. All ducting	should be installed as smooth, straight and taut as possible, avoiding any unnecessary bends or loops and trimming any excess. Once ducting runs are positioned properly they should be securely fastened to avoid shifting due to motion of the vessel. Plastic vacuum-formed and insulated aluminum transitions are available for proper air-flow distribution into any cabin or area. Ducting should be properly secured to these transitions to prevent air flow leakage. Built-in plenums or chases must be sized properly, completely sealed and insulated. Reinforced marine grade hose should be used for seawater circuit. All fittings must be double hose clamped. The hose should be rotated upward from the thru-hull intake to the unit to prevent air locking the centrifugal sea water pump. Condensate drains must be routed downward without any kinks or restrictions to a sump or overboard discharge and securely fastened. Do not terminate condensate drain line in bilge, as vapors can travel up the drain line and mix with return air. Circuit breakers and wire gauge must be sized according to marine design standards. Only stranded tinned cooper wire should be used. All equipment should be properly grounded and bonded. In keeping with regulations set forth by the EPA, only certified technicians should perform service, or make adjustments to, the refrigerant circuit.

UNBELIEVABLY QUIET OPERATION due to our unique mounting isolator bushings, insulated blower chamber and rotary or scroll compressors - many of our customers have actually mounted our units under their bunk!

COMPLETE INSTALLATION KITS come with everything needed to install the unit except for the power supply wire and breaker.

Multiple grills and ALUMINUM plenum are standard - Our duct kits come with an aluminum plenum and directional grills - There are no galvanized sheet metal components.

BRASS and STAINLESS COMPONENTS are standard except for the pump fittings which are nylon or PVC

TOTALLY PRE-WIRED - All of our units are totally pre-wired onto two clearly marked terminal blocks - any standard thermostat will operate all of our units. Our emphasis is on simplicity of design while incorporating the highest quality components with multiple safety controls.

EXCEPTIONAL SAFETY - Built in circuit breaker, triple heating element safety controls as well as dual high pressure safety shutoff controls make our units the safest available!

VERY easy to start! Soft start capacitors, stratified start up sequence and time delay compressor circuits in combination with our rotary or scroll compressors make our A/C units start effortlessly - our 16,500BTU unit should be on a 25 amp breaker!

LOW start up surge! The start up surge of these compressors is a fraction of the dinosaur like piston compressors! Millions of these compressors have been used for many years in window units - the piston compressors simply cannot meet the minimum energy efficiency standards.

DRY drain pans! The rotary and scroll compressors do not sweat and therefore do not sit in their own condensate! All of our single evaporator models (less that 48,000BTUs and the low profile FMAC16PLP) have dry drain pans - there is a small drain pan only under the evaporator!

The following kit prices include EVERYTHING you will need for installation except the power supply wire and breaker - there are NO LAST MINUTE ADDITIONAL CHARGES for cables, multiple duct kits, sea water kits, handling, crating, boxing etc. The ONLY additional expense is the shipping and sales tax if applicable - Florida residents only.

Because we simply have almost no returns whatsoever, we have no need to sell factory reconditioned units - we must be doing something right!.

CUSTOM SIZE UNITS ARE OUR SPECIALTY such as the low profile 16,500 BTU self contained unit shown to the right - only 10.5" high!!

This new model, the FMAC16PLP features a low profile piston compressor and has all of the standard features of the FMAC16R.

Electric Heat vs Reverse Cycle

Brought to you by Flagship Marine, Inc.

The two typical means of producing heat in marine HVAC units are resistive electric and reverse cycle. Although we can and have manufactured both types, we normally stock and sell the resistive electric for many different reasons which we will outline on this page.

With a reverse cycle heating system, a reversing valve reverses the flow of refrigerant, making the condenser an evaporator and the evaporator a condenser. We will outline the benefits of each system for your consideration.

BENEFITS OF REVERSE CYCLE HEAT:

Reverse cycle systems are a more efficient means of producing heat when compared to resistive electric heat.

In domestic applications these systems can save homeowners thousands of dollars/year in electric bills when compared to electric heat, however the initial cost can be significant in colder climates where underground heat sinks are required.

In marine applications if you are a live aboard with metered electric and have a water temperature in the heating season that is always above about 45-50°F, reverse cycle heat may be right for you.

BENEFITS OF ELECTRIC RESISTIVE HEAT:

Extended component life. You are not using the compressor and raw water pump for heat. The only moving part is the blower.

Electric heat units will work ANYWHERE - not dependent on water temperature. Reverse cycle heat will not work with a raw water temperature below about 45-50°F and the compressor is stressed near these temperatures. The standard 2KW element we have on our 16,500 BTU units are presently used on the Canadian Coast Guard 47' survival craft, and have heated the USCG 47'MLB for the past three years from Maine to the Virgin Islands.

You may winterize your cooling system and close your through hull ball valve. No raw water is needed for electric heat therefore you will not have the hazard of an open through hull fitting that may freeze in a power shortage and possibly sink your boat.

A "straight cool" marine A/C with electric heat is much more simple and trouble free. There is no need for a reversing valve that is notorious for sticking, and no need for a heat pump thermostat, or the extra relay, refrigerant tubing and wiring to operate this system.

You will be able to heat your boat even in dry dock.

Electric heat is more quiet than the reverse cycle heat, especially if a piston compressor is used.

The condenser in a reverse cycle unit in the heat mode will get very cold and possibly develop ice and sweat. This is why most reverse cycle units have the condensers in the horizontal position so that they will not drip on the blower motor, and why most reverse cycle units have a full wet drain pan. Our condensers never get cold and can therefore be mounted vertically, over the blower motor. Our drain pan need only be under the evaporator, making the likelihood of condensate splashing out of the pan in a heavy sea unlikely and keeping the components dry.

The installation do's and don'ts of self contained marine air conditioning

Installation location and ducting:

Self contained units MUST be placed inside the air conditioned area of the vessel - NEVER let them suck bacteria laden bilge fumes or possibly the carbon monoxide laden air from an engine room.

Typical installation locations are under a settee, under a bunk, at the floor or ceiling of a closet, under the V berth, on a shelf at the ceiling level, etc. Like all HVAC equipment, it is good form to place the slowly dissolving chlorine tablets such as "Kontrol" in the wet drain pan to combat mold/mildew etc. a few times a year.

There is no need for return air ducting - these units are like vacuum cleaners, sucking air from whatever compartment they are in and blowing the cooled air through the discharge duct-work system. If you use our pre designed ducting system you will be assured of having the correct amount of air flow and air velocity to successfully de-stratify the air in a properly sized application without having excessive noise or uncomfortable drafts.

We manufacture vertical or side discharge units - although it is possible to change this after production it is difficult to do so and we don't recommend it.

To greatly simplify the discharge ducting, we supply aluminum plenums that bolt directly onto the blower flange that have the correct number of 4" holes in them for the size of the unit. The 4" flexible ducting springs out against these holes and terminates at the 4" discharge grills. Do not push so much duct into the plenum so as to create a blockage. Do not block off any ducts - this will reduce the airflow over the evaporator which may cause the unit cycle on the freeze control.

Because our units are so powerful for their size, we do not supply variable speed fans, however you will not be bothered at all by the fan noise- these units are very quiet. Ironically, many electric motors actually make more noise when they are throttled down in speed, sometimes negating the reduced air noise.

If you design your own ducting system, do not have excessive runs of ducting or restrict the air flow return. If inadequate air is passed over the evaporator, the unit will develop frost on the evaporator and will eventually ice up unless it is equipped with a freeze control, whereby it will cycle on and off.

Our units are designed to bring the air temperature down to about 70°F - if you try to attain a lower temperature you will either develop a freeze up or cycle on the freeze control.

NEVER CHECK THE FREON PRESSURE! There are no hoses, seals or gaskets to leak - this is a totally closed system that is of a "critical charge" type, using a capillary tube - even the small amount of freon lost by connecting and disconnecting the gauges may affect the units performance. There is no need to ever check this pressure for if it were to be low on charge there would have to be a leak and a need for the unit to be repaired on the bench - this is an almost non-existent situation.

Plumbing:

One of the many advantages of self contained units vs a chiller system is that there is no need for insulated water lines, expansion tanks, circulating pumps, etc..

The intake through hull should be as low as possible in the water in a location that is always underwater and not exposed to the backwash of the propellers whereby air bubbles could be ingested. Almost every marine air conditioning pump is a flooded volute pump and must be mounted below the waterline. For boats that are in dry storage, you may install a T fitting at the discharge of the pump with one line running to a vertical location with a valve for releasing the back pressure to ease initial priming.

The unit's discharge through hull fitting should be between 4" and 8" above the waterline - if below 4" it would have to be treated as a "below the waterline" through hull and would be required to have a valve - above 8" the noise of the running water may be bothersome.

Care should be taken to avoid crimping the suction line. If long runs of plumbing are required or if the unit is placed well above the waterline you may end up with too much head pressure necessitating a higher volume pump. We have a variety of pumps in stock, and the charge to increase the GPM capacity is nominal - see our pump page.

The sea water requirements for cooling our equipment is about 200 gallons/hour/ton of air conditioning (12,000BTUs) at a maximum temperature of 100°F. The only metal the salt water touches is the inside of a 90/10 CuNi condensing tube which is inside a copper shell. We do not use a serrated or knurled tube to increase the surface area because we find our slick inner tube to be less prone to trap debris - we make up for this loss of surface area by extending the length of the condensing tube ensuring long term trouble free operation.

All of our condensing tubes are 5/8" OD until you reach the very large units whereby we use a 3/4" OD tube. For systems of up to about three tons of A/C, a single 3/4" intake through hull set up is adequate - larger systems may need a 1" or larger, depending on the total GPH requirements.

In multiple unit installations, we often suggest using one large pump with a pump relay box whereby each unit has a 24 volt wire returning to the pump relay box (usually mounted by the pump), and if any one of the units engage, the pump will supply water to all of the units.

Depending on the number of units and pump size, we often run one 1" supply line from the pump from which 5/8" T's supply individual units. The sea water discharge from each unit can be individual by each unit or tied together into one or more discharge through hull fittings.

Electrical:

All of our units are pre-wired onto two clearly marked terminal blocks. We recommend the use of GFI (ground fault interrupt) breakers for our equipment.

Be sure to use the proper size wire for our equipment. Undersized wire or poor dock/ship connections will result in a voltage drop that may damage the equipment. Many marinas have inadequate wiring - we suggest you test the dock line voltage during peak loads - it may be 120 volts on a cool weekday morning and 95 volts on a hot weekend afternoon!

The high voltage block has three connections for the power supply and three connections for the pump. This terminal block is clearly marked, however if you wish to confirm which is which, the heavier gauge wires are the power in and the lighter gauge wires are the pump output terminals.

The low voltage block connects to the digital control - we use the HVAC industry standard - red, white, green, yellow color code - any domestic thermostat will operate any of our equipment and you will never have to helicopter in a rocket scientist to figure out our digital control, in fact, one can cross all of these wires except the white for cool or all of the wires except the yellow for heat! The 24 volts for the digital is produced by an internal transformer.

The internal electronics of our digital control are powered by two AA batteries, therefore these delicate components are not subject to line voltage spikes, etc. To replace these batteries simply remove the four #1 phillips head screws on the face plate to access the batteries.

You will find a reset-able breaker on all of our equipment - safety is our primary concern and we strive to make our equipment as fool proof as possible.

Our unique and time tested heating element does not "burn" the air - it never gets red hot because it is in the direct discharge of the blower motor - these elements are actually mounted inside the blower chamber and now have a controlling Klixon that affords one a "post purge feature" (the fan continues to run until the element is less than 110°F after the element is de-energized) and TWO high voltage, high temperature safety shut off Klixons in series, the higher temperature one is manually reset-able.

Never turn the unit off by the panel breaker - this will defeat the post purge feature and possibly trip the safety shut off Klixon which is set at a mere 150°F. Always turn off the heater at the digital control and allow a couple of minutes to pass before turning off the power to the unit if you must.

There is no need for the troublesome reversing valves and component wear and tear for heat - the many benefits of electric heat far outweigh the slightly more efficient reverse cycle heat and you will find the reliability and simplicity of a straight cool unit to be a great advantage. Please visit our "Electric Heat" web page.

The use of rotary or scroll compressors has greatly reduced the problems with "start up surge" - and we have further reduced this surge by installing as standard equipment, hard start capacitors on all units over 12,000BTU's (scroll compressors excluded- negligible start up surge already). Typically, the dinosaur like piston compressor have a 350% start up surge, the newer rotary compressors a 150% start up surge (without the hard start capacitor- about 120% with!) and the scroll compressors a mere 110% start up surge.

Campervan style air conditioners. This would be a quick and dirty way to install aircon for a single cabin.

These run on 115VAC so transformer would be needed. Cheap and easy, though.
