What is

is a two pipe heat pump system, which is available from 5Hp
(single module) up to 40Hp (combination multiple outdoor units together). Up
to 40 indoor units can be connected to one system, reducing installation
material cost, and installation time. Combined with the many control options on
offer, the system can offer a total building solution.

61799 LG Multi V Catalogue 4/5/07 2:16 pm Page 18

Installation Space

User satisfaction is further increased with , by reducing the
installation area through efficient utilisation of space assisted by the design of the
outdoor unit.

High efficiency linear control

allows capacity control in the range of 10-130% according to the
indoor units load requirement. This is carried out by applying the optimised
control algorithm using the inverter and constant speed compressors as the load
increases/decreases. Combined with the outdoor unit inverter fan motors, this
highly efficient inverter system also offers low noise operation, outstanding load
response (quick and comfortable cooling and heating), and excellent energy
reduction.

outdoor units to be placed directly next to each other - offering

reduced installation space, and reduced system footprint.

Long and reduced field piping for flexible installation

gives you the ability to connect multiple outdoor units together to form
one system (therefore one set of pipes entering the building). This coupled with the
long field piping runs makes the system not only very flexible in the type
of buildings where it can be installed, but can reduce installation costs and even
reduce installation space (especially within the risers).

(depending on whether or not cooling or heating is required). Heat that is
removed from one room can be used elsewhere within the system where it is
required, thus making the even more efficient. The

Zoning after building alterations

Because each indoor unit has the ability to change mode whenever it chooses to do so, if the
building layout changes (more partitions are installed), the indoor units will control
individually as before. With conventional systems (designed only to the previous building

Fast mode change response

When the operating mode of an indoor unit is changed (i.e. from cooling to heating or visa

is it fast for the room concerned, but also there is little or no capacity loss for all other units on
the system. Therefore mode changes can happen comfortably and quickly for the entire system,

What is

Outdoor unit

is a two pipe heat pump system, specifically designed with internal
installation in mind. The air induction and air discharge are located on the same
side, which is ideal for installing against a louvered wall. is available
in 5Hp and 10Hp models, and up to 16 indoor units can be connected to one
system. Combined with the many control options on offer, the
system can offer a total building solution.

61799 LG Multi V Catalogue 4/5/07 2:17 pm Page 44

has the following differentiating features

• Air induction and dischange is combined on the same side, allowing easy installation to a louvered wall
without the need to install expensive and time consuming duct work.

• Powerful sirocco fans discharge the air to the left and right, preventing air short cycling between units
installed next to each other and between floors.

• Fully inverter driven for higher efficiency and reduced operation noise.

• Piping can exit the unit from the left or right front panels, depending on installation requirements.

• Because of the design of , less area is actually required for the installation of the unit,

compared to convential systems installed in the same way.

• The External Static Pressure on the fans can be increased up to 140 pascals if ducting is required to be
fitted to the outdoor unit. This is done by carrying out a setting on the main PCB.

Cutting edge technology and design set a new
standard for outdoor units

Unlike existing units which are awkward when matched with
internal installation applications (due to ducting configuration
and the problems faced with three sided air induction), the

design greatly reducess installation area
requirement, meaning floor space can be retained for
living/working area, rather than wasted as a plant room.

The design of the means that less area is actually required to install the unit,
compared to equivalent typez of syatem used in this type of application.

Retain useable floor space by reducing plant room size

Reduction of the required installation space by up to 50% over conventional systems,
means more floor space can be retained as living/working space (depending on
application). Or if the plant room size cannot be decreased, the remaining space inside it
can be used to install more systems, or other equipment/services. Either way, this system
gives floor space back to the end user.

Design

therefore keeping the building interior safe from strong winds associated with high rise buildings.

Sirocco fans designed to withstand high building wind speeds

Building wind and reverse wind effect are stronger at higher floor levels, which can cause
discharge air to short cycle back to the induction side affecting system control. It can also
cause damage to the fans, which in turn will considerably reduce system performance.
However, is designed to generate very strong airflow (7m/s or more) to
overcome this problem. This makes ideal for use in such high rise
applications.

No interference from the discharge air between units or between floors

Because of the symmetrical design characteristics of conventional VRF systems, high rise
installation is not always recommended (due to heat columns affecting system control on
higher floors). solves such installation problems using powerful left and right
air discharge fans which throw the air outwards rather than upwards, allowing high rise
installation with no control problems on the upper floors.

Comfort & Silence

When used in residential applications, can eliminate such problems caused by
operational noise, vibration, and uncomfortable air drafts from discharge air (i.e. on a balcony).

The directional discharge air outlet eliminates hot air drafts

The sealed structure of the , coupled with the frontal air
induction and discharge, reduces the need for extra space required for air
induction, and eliminates the generation of hot air drafts, ensuring a comfortable
environment i.e. for a balcony or decking/patio area.

Reduced noise and vibration

The other advantage of the sealed structure of the is drastic noise and
vibration reduction. The noise is reduced due to the frontal air discharge design, and the
fact that the sealed design reduces ‘noise leakage’ through the body of the unit. This
means that the noise level indoors is very quiet indeed compared with conventional
system used in this type of application.

Conventional

The indoor noise level is maintained at
30~40dBA, as quiet as being in the library.
