Marine wheel heat recovery AHU is a central AC unit after several years of continuous technical improvement, carrying the technology security and innovation, the main function is to supply fresh air, and exhaust the dirty air, transfer the heat in exhaust air to new air by heat recovery wheel, thus realize energy recovery, and cooling and dehumidification in summer, heating in winter and ventilation in middle seasons. This AHU completes all heat and humidity exchange in AC plant, the treated air is delivered to each cabin through air duct, distributor.
TMU(R)-23~320 marine wheel heat recovery AHU
“TMU”： marine AHU
“R”： wheel heat recovery
“320”： 为320kW nominal cooling capacity is 320kW
Fresh air inlet unit (fresh air static pressure box, fresh air filter, fresh air pre-heater)， wheel heat exchanger, air handling section (cooling coil, heating coil, humidifier), air supply section (centrifugal fan, marine motor), air outlet static pressure box, return air unit (return air static pressure box, return air filter), exhaust unit (centrifugal fan, marine motor), electric control box, the structure is frame structure, suction type, all parts are installed on a base.
The main function of marine wheel heat recovery AHU is to conduct cooling and dehumidification in summer, heating in winter and ventilation in middle seasons. This AHU completes all heat and humidity exchange in AC plant, the treated air is delivered to each cabin through air duct, distributor.
Marine wheel heat recovery AHU sets all functional components in one; it has the advantages of convenient and simple operation, compact structure, low energy consumption, low noise, shock and swing resistance, convenient maintenance etc. The design, manufacture, delivery of AC system is conducted according to the standard of classification societies (such as “CCS”, “ABS”, “NK”, “DNV”) and “navy”, and it can be manufactured according to customer’s actual demands.
