| MARINE AIR CONDITIONING SYSTEMS |
| Marine air conditioning systems consist of two major components: the condensing unit the evaporator unit |
| Condensing units are constructed in the smallest available size to utilize any feasible installation location. Reverse cycle is available when heating is desired. Condensing units consist of the compressor, and a fluted cupronickel counter flow condenser. The condenser uses sea water to remove heat from the refrigerant. Soft copper refrigerant tubing connects the condensing unit to the evaporator that is located in the cabin space to be cooled or heated. A non-corrosive and non-conductive bake lite electrical box holds the start capacitor, start relay, and the run capacitor. This combination allows the compressor easy starting abilities on low voltage situations. Evaporator units are designed to be used with remote condensing units. The flex duct or plenum box connected to the blower will discharge air into the area to be cooled. The blower is foam insulated, thus providing for low level noise combined with highly efficient air distribution. |
| HOW IT WORKS The self-contained air conditioner consists of two major components, the condensing unit and the evaporator unit. Each of these components has it's own minor components. The blower draws warm air from the cabin across the evaporator where the heat from the air is transferred to the refrigerant which is in the evaporator coil. While the refrigerant evaporates from a liquid into a gas, it absorbs the heat from the air. The compressor now compresses the refrigerant gas and pumps it through the condenser coil. The seawater pump circulates the cool water through the inner tube, cooling the refrigerant and condensing it into a liquid. Heat from the refrigerant is exchanged to the seawater and discharged overboard. Liquid refrigerant is passed through the evaporator coil and then the entire cycle repeats. Removing the heat from the air in the cabin lowers the cabin temperature. The cooled air is blown through the ducting and out through supply air grilles. |
