| CHILLED WATER SYSTEMS |
A chiller condensing unit – consisting of three components: compressors, the “tube in tube” condenser coils and evaporators. The chiller unit is charged with refrigerants that circulates throughout these components. These units are designed to be installed below deck and are not affected by vibration or moisture. It is hermetically sealed and needs no ventilation for operation. Air handlers installed throughout the vessel with fresh water piping connecting the chiller to the air handlers – consisting of two components: the blower and a coil. This enables fresh water to circulate within the piping from the chiller to each air handler. Sea water system |
| Chilled water air conditioning systems are the ideal solution for yachts from 60 to over 200 feet. Most chillers feature multiple compressors and refrigerant circuits for efficiency and maximum power, Chilled water air conditioning systems consist of : |
DEFINITION OF TERMS Air Handler – The fan coil unit which circulates air into areas for heating/cooling. Chilled Water Circulation Circuit - Supply and return piping from the chiller to the air handlers. This piping carries chilled from the chiller to the air handlers. Return piping carries warmed water back from the air handlers to the chiller. This piping forms a continuous closed loop. Chilled Water Circulation Pump - A centrifugal pump used to circulate fresh water from the chiller and the air handlers for heat transfer. Fresh water fill System - Components which are installed on the return line to the chiller for filling the circulation circuit pipe system. Sea Water Pump - A pump and motor combo that provides a continuous water flow throughout the condenser coils. |
| HOW THE CHILLED WATER SYSTEM WORKS: In the "cooling" mode, the blower draws the warm air of the cabin the air handler coil. Removing heat from the cabin air cools it and then the cooled air is blown back into the cabin. Heat from cabin air is transferred to the fresh water and circulates through the coil. In turn, the warm water is pumped back to the "chiller." This water is then circulated through evaporators where heat is transferred to the refrigerant in the coil and thus creating the "chilled" water. The chilled water is ultimately pumped back through the piping to the air handlers in a continuous loop. |
