RefrigerationThe refrigeration system is a 12VDC FrigoBoat Holding Plate system driven by a Danfoss BD50 compressor. The compressor is mounted on the upper shelf in the engine room, and is cooled by sea water pumped through a ShurFlo diaphram pump. The water pump is mounted on the engine room forward bulkhead directly below the fresh water pump. Sea water is sourced from the raw water strainer via a "tee" fitting and shares the same seacock as the engine cooling system (so DON'T CLOSE THE ENGINE COOLING SEACOCK AND TRY TO RUN THE REFRIGERATOR!!). An hour meter attached to the pump is mounted on the inside of the galley cupboard and keeps track of just how long this amazing refrigeration system has run (as of 2/2010, a remarkable 1,978.1 hours). The refrigeration system has an optional TempTech controller and display panel. This controller automatically senses whether there is an external power source (charger or alternator) and adjusts compressor speed accordingly. The TempTech has two settings:
Box temperature can be made COLDER by turning the adjustment knob to PORT. There are two switches on the panel, one of which turns the compressor on or off, and one which controls the interior light of the refrigerator box. The compressor is fused per manufacturer's spec on the exterior of the galley drawer cabinet (port side); the light is fused at a terminal block located on the aft bulkhead just above the starting battery box. The refrigerator box itself contains four vacuum-panels from rparts.com covered with 1/8" plastic sheets 'glassed into place which provide insulation rated at R50. DO NOT EVER PUNCTURE THESE PANELS--doing so will destroy the insulation value. The rear panel has a "notch" on the upper port side so that refrigeration lines can be routed into the box. The hatch is also from rparts.com. There is a pair of wires inside the box coming from the engine room which could be used to incorporate a fan, if that was ever necessary. We've not found that to be the case, so those wire just sit there gathering moss... This system is so perfect if it ain't broke, don't #uc% with it. Air Conditioner A Mermaid 12000 BTU air conditioner with reverse cycle heat, purchased June 2006 at a cost of 3478.25 is installed and provides cooling primarily to the aft cabin, although there are also two outlets in the main salon. The main salon outlets are located above and below the "electronics closet". The upper outlet is actually a dorade vent that has been converted to use as an air conditioner outlet. The aft cabin outlet is a fabricated "plenum box" below the hanging closet. The air conditioner is wired to the starboard outlet circuit breaker, through a 30-amp wall switch located inside the electronics closet. Sea water is used to cool the condensing unit. There is a strainer located in the bilge on the port side of the mast; this strainer needs to be checked from time to time and the screen should be replaced on a regular (annual) schedule. The thruhull that supplies the water is located just aft of the strainer. The (110VAC) water pump is located beneath the starboard settee. On occassion (especially after a wild ride or indeed after haulout), the pump needs to be "primed". To do this, loosen the (somewhat cumbersome) hose connection on the top of the pump and allow sea water to escape. The system is fitted with a Condensation Removal Device. Working on the "Venturi" principle, the Mermaid Condensator is installed in-line with the marine air conditioners' water discharge line. As the marine air conditioner and sea water pump are running, the device creates a vacuum effect and literally pulls the condensation water out of the drain pan and merges it with the discharge water. The condensator needs to be cleaned from time to time. It is located on the shelf underneath the air conditioner. Fresh Water Systems Fresh water is sourced from either a municipal connection through an inlet on the port side of the house, or from the primary 115 gallon water tank, or in the case of the galley FOOT PUMP (the AFT pump--the forward pump is SEA WATER) from the 30 gallon bladder located within the starboard settee. House water pressure can safely reach 400 PSI (cold) due to the incorporation of CPVC pipe used prior to attachment to the 3/8" copper tubing that supplies all other faucets. The 3/8" copper connections are "flared" fittings, commonly used with natural gas and provide a high degree of safety. Two opposing check valves fitted within the fresh water circuit provide seamless switching between a municipal water source and the on-demand house water pump (see diagram below). The check valves (SharkBite product U2008) have a cracking pressure of ½ PSI. To use the on-demand HOUSE water, eliminate municipal water supply pressure (disconnect the hose or shut off the faucet) and energize the on-demand pump using the 12vDC circuit breaker labeled FRESH WATER PUMP. There are no manual valves incorporated in the fresh water supply circuit. The higher pressure source automatically closes the opposing check valve, so if the on-demand pump is on and a higher pressure feed comes from the municipal source, water will be sourced from the municipal side. Conversely, if there's no municipal water pressure and the on-demand pump is on, water will be sourced from the house tank. Major "junctions" of the 3/8" copper tubing are found below the main cabin sole, just aft of the mast. The aft toilet flushes with water sourced from the primary (115 gallon) tank. This is because the use of salt water in that toilet causes significant odor when marine organisams decompose. There is an unconnected hose in the aft head cabinet that could be used to source salt water in the event of an ocean crossing. All water except aft head toilet and manual sink pump and galley foot pump is filtered through the "whole house" water filter prior to delivery to any faucet or the water heater. The aft head manual sink pump has a two way valve installed inline, and there is a check valve on the aft head toilet supply line. The water heater is attached to the shelf in three places--two aft (both sides) and one forward on the port side. Supply (cold) to the water heater is provided through a stainless steel reinforced "washing machine" hose capable of withstanding 90+PSI. The hot water out is a rigid flared copper line.
The Reverse Osmosis water filtration system is located within the galley sink cupboard. A valve in the sink plumbing can shut off water supply to the reverse osmosis filtration system. Heads There are two heads (marine toilets) both installed AFTER 1992 (important to know when ordering the rebuild kits). The forward head is a Raritan PHE-II, the "E" signifying that it is an Electric flush toilet. The aft head is a PH-II (identical to the PHE-II except that it is a MANUAL flush toilet) and is plumbed for fresh water although this can be modified to use sea water in the event of an ocean crossing. Both heads are plumbed for either DIRECT DISHCHARGE or through USCG approved mechanisms for handling waste. The use of WHALE diverter valves as opposed to cheaper Jabsco valves ensures that there is no leakage when changing the discharge route. Discharge routes are clearly marked on the valves. The forward head is connected to a Raritan ElectroScan Type 1 Marine Sanitation Device which is activated automatically when the FLUSH button (on the vanity wall) is pressed. Rebuilding the heads From time to time, the pump mechanisms on the heads need to be rebuilt. This is a painful excercise, exacerbated by the exhorbitant cost of the rebuild kit (about $75 at West, but available for $45 from boatfix if you can wait). You can tell when the forward head needs to be rebuilt by counting the number of flushes within the 20 second flush time--any less than 23 flushes in 20 seconds and the pump needs to be rebuilt. Galley (including propane) come back again---later |
