Figure 1: Self-Contained Air Conditioning
Self-Contained Systems All major components (compressor, condenser, evaporator, and blower) are mounted on a single chassis, which is installed under a bunk, settee, or in a locker. All major components (compressor, condenser, evaporator, and blower) are mounted on a single chassis, which is installed under a bunk, settee, or in a locker. Self-Contained Systems All major components (compressor, condenser, evaporator, and blower) are mounted on a single chassis, which is installed under a bunk, settee, or in a locker. An air-conditioning unit of this type can either cool a single cabin or can be connected to two or more cabins by ductwork. The ideal solution for boats up to 40 ft (12 m) due to lower cost of units and installation.

Split-Gas Systems (also called Centralized A/C) Split-Gas Systems (also called Centralized A/C) In these systems, the condenser and evaporator units are installed separately at different locations. The two components are then connected via insulated copper refrigerant tubing connects. Note: the maximum length of refrigerant tubing is 50 ft (15 m). In these systems, the condenser and evaporator units are installed separately at different locations. The two components are then connected via insulated copper refrigerant tubing connects. Note: the maximum length of refrigerant tubing is 50 ft (15 m). • The condensing unit (compressor, seawater condenser, and electrical components) mounts in engine room or other mechanical space. • The evaporator unit installs in the living area. • The condensing unit (compressor, seawater condenser, and electrical components) mounts in engine room or other mechanical space. • The evaporator unit installs in the living area. Two air handlers can be connected to one condensing unit to cool multiple cabins or a single large area, providing a space-saving, quiet A/C solution. Two air handlers can be connected to one condensing unit to cool multiple cabins or a single large area, providing a space-saving, quiet A/C solution. Ideal for boats up to 80 ft (24 m). Note: the system must be charged with refrigerant by a certified technician. Ideal for boats up to 80 ft (24 m). Note: the system must be charged with refrigerant by a certified technician.

Chilled (circulated) Water Systems
Digital Control
Chilled (circulated) Water Systems Installed in the engine room, the chiller circulates cold or hot fresh water in a closed circuit to all of the rooms to be air-conditioned. Air handlers then cool or heat the living spaces. These systems require two pumps; one for the sea water and another for the chilled water.

Chiller systems are well suited for boats over 80 ft (24 m). This is because there is no limitation on the number of air handlers in a system, or on the distance from the chiller to the air handlers.
