Product details:
MULTIFUNCTIONAL AIR-WATER UNITS WITH AXIAL FANS AND HERMETIC SCROLL COMPRESSORS FOR ASSOCIATED SYSTEMS WITH 4 PIPESOutdoor temperature: -15°C
Max output temperature: 60°C
The four-pipe technology is considered the best energy efficient solution able to satisfy the complex needing of all those buildings where it is necessary to neutralize simultaneous opposite thermal loads. QUATTRO, operating in total heat recovery mode, is able to satisfy the simultaneous demand of hot and cold water all over the year, simplifying the plant and reducing operating costs.
Available in two different efficiency levels:
A. STANDARD EFFICIENCY
B. HIGH EFFICIENCY
Versions
MA: Multifunctional air-cooled unit.
L/E: Acoustic versions.
B1/A1/B2/A2: Hydraulic versions on cold side (evaporator)
L1/H1/L2/H2: Hydraulic versions on hot side (condenser)
Advantages
• High energy efficiency assured by oversized heat exchange coils and high energetic performance fans.
• EC Fans. Due to the innovative profile, these fans ensure high efficiency by reducing power input and sound emissions.
• Easy installation and maintenance.
Thermocold Adaptive Refrigerant System™: a proprietary technology, which automatically optimizes refrigerant charge and sub-cooling in each operating mode and varying temperature conditions, delivering additional performance and efficiency gains.
TER is the unique index officially recognised by Eurovent for measuring the performance of a multi-functional unit while it is working in simultaneous cooling and heating mode.
It is calculated as the ratio between the sum of the heating and cooling capacity supplied to the plant and electrical power input. The TER reaches its maximum value when the two opposite loads are completely balanced.
The more balanced are the plant loads, the higher is the TER.
The multifunctional systems are the most powerful solution with low operating costs, both in terms of plant simplicity that the energy saving due to the total energy recovery.
