EUROPAIRITALIA

The market of cruise ship, ferry and offshore

living quarter is growing in continuously.

Many people are daily around in different parts of

the World with various weather conditions.

The passengers demands are always the same :

• comfort in air-conditioning

At the same time, the shipping company needs

to save the necessary energy used to obtain

the “Passenger Satisfaction”; that means saving

the costs and increasingly or recovering the

business profits.

In commercial air conditioning installation,

the “BMS” Building Management System is

normally used just to obtain the maximum

performance from the air conditioning system.

In marine or offshore cabin market, this

management system type is not yet used

also because it is necessary to change some

components and study a new functioning logic.

Europair have developed a new cabin

unit with a regulator that meets this

requirement.

With our system you can obtain :

• constant high passenger comfort

• commissioning cost reduced to

minimum

• cabin management from control room

• cabin status and data communicated

via Network (Ethernet or Mode-Bus)

• energy saving thanks to the “pressure

independent” system and special

management program

• safety system with 3 different security

levels.

TECHNICAL DATA

The new regulator have the Ethernet integrated module

INTRODUCTIONSystem available on the marketNow the air regulation for naval applications is usually done by “pressure dependent” VAV semiautomatic cabin

unit. The damper setting by an electric motor adjust the air volume flow necessary to guarantee the requested

parameters for room comfort. The electronic regulator for this cabin units changes the air flow depending on the

passengers requests or the room temperature fluctuations only with the input from room temperature thermostat.

During this operation the motor moves the damper for regulating the air flow to satisfy the request but the

damper value regulation must be in the rotation corner position preselected during the commissioning.

Rotation corner setting :

The corner setting according to the technical data is done in the following way :

- measure the supply air flow in the cabin by measuring tools with complete open damper

- manual or electric closing of damper up to the reaching, after several attempts, of the required value for max

air flow

- the same operation is necessary for adjusting the minimum air flow

- setting of the 2 position max - min air flow by electronics or mechanical switches for limit the damper rotation

according to the data measured during the 2 precedent operations

- after the damper operation setting, it is necessary to check again the air flow and adjust other times the

switches for changing the rotation motor corner after a series of cabin adjusted.

Anyway, the method depends on the static pressure in the duct that can change as a consequence of every

single cabin different request. This typology is “Pressure Dependent” because it is unable to control the air flow

but only to change the damper position for temperature changing. The main problem consists in the adjusting

of air flow only when the thermostat feels the changed temperature or for a different room request; with this

regulation the HVAC system will be in continuous fluctuation.

New patented “pressure independent” systemWith our system any previous setting of damper rotation is necessary and the motor can open or dose the

damper without present limits. For adjusting the air flow it is necessary to connect a note-book or central computer

to our MPV1 80 directly on regulator, in technical space or in control room via cable, enter the program, search

the setting page, open the correct cabin unit, insert max and min air flow and push OK.

The setting is complete.This opertaion is possible also without air in the duct. If there is air in the duct, depending of room thermostat

request, the regulator sends the necessary input to the motor for moving the damper to obtain the requested

air flow.

When the room temperature is correct, the motor remains in that position. But in case of change of the static

pressure in the duct also due to different requests in other cabins, the air flow measurement sensor sends the

information to the regulator that the air flow is not correct; now the MPV180 sends a new input to the motor to

change the damper position up to the reaching and the return to the correct air flow; this operation happens

before that the temperature really changes in the cabin without HVAC system fluctuation and expecially with the

constant comfort for the guest.

This is the “PRESSURE INDEPENDENT” system.

ally chahat the t

stant comfort for the guest.

This is the “PRESSURE INDEPEN

This regulator is suitable to adjust the max and min air flow and to maintain the requested value also if the air

static pressure changes in the duct (Pressure Independent).

The air flow changes depending on the room temperature request or following special program.

SafetyOur regulator is provided with internal safety devices :

- control of min default air flow for switching ON the heater; in case that the air flow is lower than the default value

(customer indication, 50-100 m3/h), the eletrical power will be shut-off

- air temperature sensor into VAV unit; when the air temperature increases up to the max set temperature (normally

at 55°C), the electrical power will be shut-off. Within the manual reste thermostat the VAV unit (normally

set at 90°C) we have 3 safety levels.

FUNCTIONINGCoolingWhen in the cabin cool is required, the room thermostat sends an input to the MPV180 that operates the motor

wich opens the damper increasing the cool air flow.

The room temperature is now decreasing and when it arrives close to the requested one, the MPV 180 regulator

will start to close a little the damper. When the room temperature reaches the request temperature, the damper

remains at the balance position; this condition remains constant up to a different room temperature request or

if the static pressure in the duct changes. If the static pressure in the duct changes, the air flow changes but

thanks to the air flow sensor, that continuously sends the information to MPV180, the correct air flow necessary

to keep the room requested temperature is manteined.

HeatingWhen in the cabin warm is required, the room thermostat sends an input to the MPV180 that operate the motor

the damper making the cool air flow decrease. When the air flow is close to the minimum, the PWM power

regulator switches-on the electrical heater at the max power and when it arrives close to the requested

temperature the PWM regulator reduces the electric power up to a balance condition with minimum air flow

and correct electric power. As for cooling operation, the balance is kept until a new change or for example in

the static pressure the duct changes.
