Roccheggiani offers two different solutions for air conditioning of offices:
Chilled Beams system
The best solution in an integrated system
The ideal solution Roccheggiani proposes for the air conditioning of offices, both partioned and open-space, is a system made up of an air handling unit with on board integrated regulation and chilled beams used as room terminals that provide cooling, heating and ventilation. This system can be optimized by the employment of the innovative three stages recovery RRU-FA air handling unit.Each room is self-managed by the control panel that allows to adjust the temperature to the desired level.
Roccheggiani RRU-FA Plug&Play
The air handling unit is the core of the chilled beam system; it provides the renewal of air in the rooms, as specified by the actual rules, and ensures the correct humidity level.
Stand-alone unit for primary air
Three recovery-phases for the maximum energetic efficiency
Centrifugal fans, directly coupled, of Plug-fan type, with EC electronic engine in direct current and with automatic control of the airflow
Enthalpy rotative recuperator, with enhanced hygroscopic characteristics, with total recovery up to 85%
Integrated heat pump and refrigerating circuit with thermodynamic active recovery and warm fluid bleed off
Digital Scroll compressors and electronic valves
Maximum ESEER ratio for refrigerating units dedicated to chilled beams (thermal level of beam circuit AR=14-18°C)
Maximum ESEER ratio for integrated primary air handling units
Energy saving: up to 20%, compared to a chilled beam system with single refrigerating set and double hydraulic circuit
TFS2 is an active chilled beam with 2 way air spread pattern, developed for false ceiling installation. Thanks to the aesthetic aspect, linear and clean, with extruded aluminium profiles that guarantee a perfect linearity, it is particularly suitable for the application in offices, both partitioned and open-space. It is equipped with the patented Roccheggiani air modification launch system that guarantees no performance reduction, and also with the integrated system for regulating the air flow rate. It is available in any colours. All mechanical parts, including control valves and actuators can be reached by opening the bottom panel. The visible portion is independent from the length of the active part. The TFS2-L version has the same performances of the TFS2 one, but integrates two modern lighting bodies on the unit profiles that ensure a comfortable lighting of the environments.
TFS2 / TFS2-L chilled beam system for false ceiling mounting provides the following advantages:
Ambient noise levels very low due to the absence of moving parts Maintenance costs almost absent (no filters, no condensation drainage networks, lack of moving parts that can be damaged)
Simplicity of the system (absence of power cables, and no condensation drain ducts)
A perfect architectural integration without any floor occupation with the possibility of integrating lighting bodies on the unit profiles (TFS2-L)
High energy efficiency of the system
Uniformity of temperature in the environment
High standards of hygiene thanks to the absence of filters and points of condensation on the unit
Onboard integrated automatic regulation
System based on a programmable microprocessor control, specifically programmed for efficiency improvement of HVAC/R systems; it controls and monitors the AHU’s functions and setpoints, communicates with the office supervision system for a sensible management of energy consumption.
Some main characteristics of the Connectivity System are:
it can work with distributed intelligence and with integrated solutions, receiving and sharing information from and with third party devices in order to:
Possible supervision of the whole Building Management System with dedicated and customizable architectures.
