POMPE DE CALDURA, AER CONDITIONAT, CHILLER

Residential chillers and heat pumps

Climaveneta > Commercial and industrial heat pumps

RECS 1052 – 1952

Reversible unit, air source for outdoor installation Cooling capacity 189 – 399 kW

NECS 0202T - 0612T
Outdoor unit in heat pump mode for the production of chilled/hot water with semi-hermetic screw compressors optimized for R134a, axial-flow fans, condensing coil with copper tubes and aluminium fins, plate heat exchanger 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.

    Extensive range of operation with external air temperature up to 46°C in summer and down to -10°C in winter with LT version
  • HOT WATER SUPPLY
    Supply of hot water in use up to 55°C, offering maximum versatility with respect to different plant engineering solutions
  • STANDARD WATER PUMP
    Standard water pump with pump unit options and possible storage tank: 1 or 2 pumps, 2 or 4-pole motor, for high or low head

Accessory

  • 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

Controls

  • W3000SE Large
    The W3000SE Large controller offers advanced functions and algorithms. The keypad features an easy-to-use interface and a complete LCD display, allowing to consult and intervene on the unit by means of a multi-level menu, with selectable language setting. 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. 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 defrost adopts a proprietary self-adaptive logic, which features the monitoring of numerous operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
