Marine direct AHU is a central AHU after several years of continuous technical impovement, carrying the technology security and innovation, the main function is to epuip with marine compressing-condensin units and conduct cooling and dehumidification in summer, heating in winter and valtilation in middle seasons.
It is mainly composed of air handling unit(fin type evaporator, heater and humidifier), air supply section(centrifugal fan and marine motor), mixing and filtering section(mixing box, fresh and return air regulation valve, air filter), electric control unit, the structure type is frame structure, suction type, all parts are installed on a base.
The main function of marine direct AHU is to conduct cooling and dehumidification in summer, conduct heating in winter and valtilation in middle seasons. This AHU completes all heat and humidity exchange in plant, the treated air is delivered to each cabin through air duct, terminal units.
Marine direct AHU sets all functional componets in one; it has the advantages of convenient and simple operation, compact structure, stable performance, low energy consumption, low noise, shock and swing resistance, convenient maintenance etc.
Air flow: 2200~25000m3/h
External static pressure： 450~1600Pa
Refrigerant: standard epuip R404A、R134A、R407C and some other refrigerant can be selected.
Single circuit evaporator can be selected;double circuits also can be used.
Washable/replacedable air filter
Freash air preheating unit, auxiliary electrical heater and cold air prevention device can be set according to requirements.
Control componts: adopt the control valves and pressure switches of domestic and overseas famous brands.
Control method: manual control or automic control, generally, juction box is equipped, main control is realized by electric control box in compress-condensing unit
It is widely used in all kinds of passenger ships, cargo ships, warships and offshore oil platfroms
