Marine/Systems/Enigma Fan Coil air conditioning system with energy recovery by enthalpy exchanger.
This system combines state of the art energy recovery combined with maximum comfort for the passenger.
A minimum of fresh air (based on fresh air per person) is treated in the air handling and distributed through the thermally insulated spiro duct system to the CFCU unit that is placed in the wet module of the cabin. In the CFCU the fresh air is mixed with the return air from the cabin and supplied to the cabins through ceiling boxes with diffusers. This system drastically reduces the number of AHU, size of the chillers and ducting needed on-board.
During winter, the exhaust air is hot and humid compared to the outside air. The enthalpy exchanger transfer humidity and temperature to the supply air, without mixing it. It is then pre-heated and humidified in the air handling unit. The air is re-heated in the cabin unit based on input from a room thermostat with adjustable set point.
During summer, the exhaust air is cold and dry compared to the outside air. The enthalpy exchanger transfer humidity and temperature to the exhaust air, without mixing it. It is then cooled in the air handling unit.
It is delivered with a user panel (with thermostat) and can be connected to a balcony door switch and key card reader.
Some fans are required to complement the function of the Teknotherm Re-Heat air condition system, commonly referred to as Accommodation Exhaust Fans.
