Excellence with MULTISET VRF
systems
Energy saving + maximum efficiency +
easy installation and easy maintenance
Technibel MINISET and MULTISET VRF
systems offer the most advanced technology for air conditioning
centralized systems.
Our range of VRF includes excellent systems dedicated to:
- commercial applications (2/3-way MULTISET)
- light-commercial applications (MINISET or 2/3-way MULTISET)
- residential applications (MINISET).
The coefficients of performance are exceptional, in both Cooling
and Heat pump modes, making it possible to benefit of big savings in
terms of energy consumption. This feature is strongly evaluated in
all Europe, leading to important savings in energy costs and
contributing to respect the agreements of
Kyoto relating to energy saving, with the reduction of greenhouse gases.
In many European Countries the investments primarily made by the
citizens in MINISET as heating systems in spite of a traditional one, gas
or fuel energy sourced, are rewarded with fiscal benefits, depending
on the Financial Law of each particular country.
Both MINISET and MULTISET VRF systems
use the same Indoor units, which can thus be connected to three
different types of Outdoor units:
- Outdoor units for MINISET VRF systems
- Outdoor units for 2-way MULTISET VRF systems
- Outdoor units for 3-way MULTISET VRF systems
MINISET and MULTISET are direct expansion
air conditioning systems with VARIABLE
REFRIGERANT FLOW based on two technologies:
- the technology of R410A, the most ecological and efficient
refrigerant now availble on the market and
- the technology of PAM (Pulse Amplitude Modulation) DC Inverter electronic control.
The result is a top energy efficiency product , with Coefficient of
Performance (C.O.P.) up to 4,09.
The installation of the MULTISET systems
is easy and can be realized "step by step" without
difficulties: it's possible to begin with one outdoor unit only and then
add other outdoor units to reach the required total capacity. The units
installed at the beginning go on operating without
modifications.
The total capacity of a 2 / 3-way Multiset system can vary from
22,4 kW
to 135 kW (48 HP) using up to 3 outdoor units; the Miniset can be used for systems with a total capacity of 11 kW, 14 kW
and 16 kW.
The maximum number of connectable Indoor units is 9 for MINISET
systems, 40 for MULTISET systems.
The total piping length can reach 300 meters
with a lower quantity of refrigerant (-21%).
Other special features are available when 2 units (or more than 2)
operate in parallel:
1. For instance, the system is able to automatically acivate a
special electronic control system of the Outdoor units, called
"BACK UP", that in case one unit stops
operating or is in error, makes the system go on fonctionning,
waiting for a technical intervention: the sophisticated control system
compensates the bad operation of the blocked outdoor unit, distributing
the thermal power to the other outdoor units of the multiple
configuration system.
2. Another feature, called "LONG LIFE",
consists of an electronic system that controls the operating cycles of
the compressor, distributing the loading and extending the efficiency in
the time (in case of more "Constant spee" units).
The low sound level is a key factor for
MULTISET Outdoor units; thanks to the special fan and to the careful
study of the air movements in suction, the sound power levels have been
reduced of more than 4 dB(A) in comparison with the prevoius models.
The compactness of the outdoor units allows a very
flexible installation. Only
10 cm of distance are necessary between two outdoor units:
the space required for the installation is
small and the displacement of the units
made easier.
Another key factor of these outdoor units is their capability to
operate in extreme outdoor air temperature
conditions : MULTISET can be practically installed everywhere.
The operating range is:
- from -10°C to +43°C in Cooling Mode
- from -20°C to +15°C in Heating Mode
