1.1 Features
The Daikin Marine Type Packaged Air Conditioners have been developed with Daikin's own technique and
achievements accumulated exclusively in air conditioning for more than half a century, considering special
and rigorous conditions on the sea such as intensive vibration due to pitching and rolling of a ship and
corrosion caused by sea water and breeze. All the necessary components are compactly encased in a single
casing so that limited space in a ship can be used effectively for air conditioning.
The installation work is simple; all you have to do on the site is to provide piping for condenser water and
condensation disposal and wiring. All the air conditioners are ready for work only when the power is
supplied. The smaller units can be ideally installed in a cabin and engine room, and all the units can be
installed easily regardless whether ships are new or old.
The Daikin Marine Type Packaged Air Conditioners ensure comfortable voyage and working on the ship.
Use of new refrigerant friendly to earth
The Daikin Marine Type Packaged Air Conditioners uses the new refrigerant R407C which contains hydro-
fluorocarbon (HFC) and of which ODP is zero. This means the new refrigerant is more friendly to the global
environmnet in comparison with the conventional one (HCFC22) of which ODP is 0.055.
Careful safety measures
If the Daikin Marine Type Packaged Air Conditioners are out of order, their operation is automatically
stopped by various safety and protective devices listed below before trouble occurs.
¡ Electric system
Overcurrent relay, compressor thermal protector.
¡Refrigerant system
High pressure switch, Low pressure switch, fusible plug or condenser safety valve.
Excellent durability
All the Daikin Marine Type Packaged Air Conditioners are specifically designed in consideration with unique
conditions on ships such as bending, torsion, elongation caused by rolling and pitching of ships, corrosion
and rust caused by condenser sea water and sea breeze, etc.
¡Condenser and its relative parts
Adoption of copper alloy for such parts which are in contact with condenser sea water, naval brass clad steel
plate for tube plates, bronze casting for head and rear covers, and aluminum brass for cooling tubes.
¡Evaporator and its relative parts
Anti-corrosive treatment on evaporator fins against sea breeze.
¡Structure and design
Application of anti-corrosive paint against sea breeze and anti-quake structure.
¡Fan and its relative parts
Improvement of bearings and reinforcement of fan frame.
Versatile optional accessories are available for easy alteration
¡ Fresh air intake duct connection can be attached (USP3H to USP10H)
¡ An electric heater, etc. can be mounted.
Wide operating range
Even in middle seasons, the units are operative in such a case when cooling is required to cool the heat
from engines.
Furthermore, if cooling is required during winter, a stable cooling operation is obtainable only when engine
cooling water (Under 38°C) is used. Operating range in high temperature zone can be widened greatly by
increasing designed pressure.
Excellent serviceability
In USP3H, the plenum chamber is separated from the unit. So the unit, now only 1,450 mm high, can be
installed even in a small space.
Development of the highly efficient and compact heat exchanger makes it possible to reduce charged
volume of the refrigerant, which enlarges service spacing in the units and also makes the anti-corrosive
galvanized plate free from maintenance. The air filter can be easily removed or mounted.
The mounted compressor is a new high EER hermetically sealed scroll one.
