The DVM(Digital Variable Multi) air conditioning system is operated by a variable-capacity compressor
and is accommodated by multiple evaporators (indoor units). It is touted as the next-generation modular
system in the world of high-efficiency air conditioning. lt has undoubtedly changed the face of cooling
associated with high-storied buildings. It provides a broad range of different applications for settings such
as offices, hotels and schools. With its easy installation and simple controlling system, the DVM will more
than meet the demands of the air conditioning market.

1-2. Features of DVM
(1) Customized air conditioner
1) Up to 16 indoor units can be connected to one outdoor unit.
2) Indoor units can be combined by various methods, according to each room’s use and shape.
3) There are several indoor units which can be applied; 1-way cassette type, 4-way cassette type,
Ceiling, Duct (Low silhouette, Built-in, High pressure), Wall-mounted and Floor standing type.
(2) Comparison of DVM with conventional air conditioners

(3) Variable compressor
The world’s first PWM(Pulse Width Modulation) compressor controls the cooling & heating capacity
automatically, depending on the load.
1) Principle of the digital compressor
Composition
①
The solenoid valve is installed for the compressor´s loading / unloading between the upper part of the
fixed scroll and the suction pipe.
Mechanism
②
a. When the solenoid valve is turned off, the fixed scroll is closed to the orbiting scroll (Loading),
b. When the solenoid valve is turned on, the fixed scroll is separated from the orbiting scroll (Unloading),
c. This process controls the On / Off times of the valve and the rotating refrigerants in the circle,
thus adjusting the capacity.
d. The cooling capacity of the outdoor unit is controlled automatically,depending on the
number of operating indoor unit(s).

2) PWM (Pulse Width Modulation) valve
PWM valve is the valve to take away the fixed scroll by lifting up through the difference of pressure after the digital
scroll compress being connected to the outlet and inlet of suction. Therefore, the capacity of compressor is controlled
automatically according to the operation status such as loading when the valve is closed or unloading when the valve
is opened. PWM means the control of ON/OFF signal to the valve for loading/unloading.

(4) Refrigerant flow rates control
Refrigerant flow rates through the electronic expansion valve are controlled by the 2 factors which are the
temperature difference between inlet and outlet of evaporator and the difference between room and set temperature.
a. An electronic expansion valve optimally distributes refrigerant flow rates to each room and the fuzzy logic enables
comfortable cooling more precisely; refer to the figure below.
b. The air conditioner senses the temperature difference between inlet and outlet of evaporator, plus the temperature
difference between room and set temperature. And it calculates the superheat and the room temperature status,
then adjusts refrigerant flow rates after deciding the opening steps of valve.

◆ The system enables the connection of indoor units with a total capacity of between 50 to 130% of that of
the corresponding outdoor unit but where this capacity ratio exceeds 100% then the actual capacity of
each indoor unit will fall a little short of its individual rated capacity when all the units are operated
simultaneously. (Except for the Middle East models)

(by a curtain for example)
◆
The remote controller is not exposed to direct sunlight or heat
◆
The wireless remote controller is at least one meter away from
a television or stereo system to avoid generating any parasites
To attach the holder to the wall, proceed as follows.
1) With a pencil, mark the positions of the two holes on the
wall where the holder is to be installed.
2) Drill the two holes and insert plugs as required for the type
of wall on which the holder is being installed.
3) Screw the holder into position.
