POMPE DE CALDURA, AER CONDITIONAT, CHILLER
FOCS 1542 – 2642
Chiller, air source for outdoor installation
Cooling capacity 252 – 516 kW
Outdoor unit for the production of chilled water with semi-hermetic screw compressors optimized for R134a, axial-flow fans, condensing coil with copper tubes and aluminium fins, shell and tubes evaporator designed by Climaveneta and thermostatic expansion valve. Frame with base in polyester-painted thick hot-galvanised sheet steel and external panels in peraluman. Flexible and reliable unit; it easily adapts itself to different thermal load conditions thanks to the precise thermoregulation. The high performance’s level is achieved thanks to the accurate sizing of all internal components.
B – Basic
LN – Low noise
SL – Super-low noise version
D – Partial condensing heat recovery function
R – Total condensing heat recovery function
Flexibility in applications thanks to the many available functions and versions
Adaptability at the building’s cooling request thanks to the continuous capacity regulation, assured by sophisticated control’s logic.
- WIDE OPERATING RANGE
Extensive range of operation with external air temperature up to 46°C at full load; with total heat recovery, hot water can be produced up to a temperature of 55°C.
- Soft start
- Compressor power factor correction
- Electronic expansion valve
- Variable speed condensation control (standard on /LN, /SL)
- Remote control keyboard (distance to 200m and to 500m)
- Set-up for remote connectivity with ModBus, Echelon LonTalk, Bacnet protocol board
- W3000SE Large
The W3000 SE Large controller offers advanced functions and algorithms. The keypad is generously sized with full operating status display. The commands and detailed LCD display make access to the unit’s settings easy and safe. These resources allow to consult and intervene on the unit by means of a multi-level menu, with selectable language setting. The diagnostics includes a complete alarm management, with the „black-box” and alarm logging functions for enhanced analysis of the unit operation. For multiple units’ systems, the regulation of the resources, via optional proprietary devices, can be implemented. Energy metering, for both consumption and capacity, can also be developed. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet, Bacnet-over-IP, Echelon LonWorks. Compatibility with the remote keyboard managing up to 10 units. Availability of an internal real time clock for operation scheduling (4-day profiles with 10 hour belts). The regulation features the continuous modulation of capacity, based on a dynamic dead band and referring to the leaving water temperature. As alternative, step-wise regulation is also available, referred to the return water temperature with selectable proportional- or proportional-integral logic.
