CLIMAVENETA: A NEW GENERATION OF CHILLERS AND REVERSIBLE HEAT PUMPS IS BORN
The new NECS is a range of units for outdoor installation, suitable for the production of chilled water and also hot water for both space heating and sanitary purposes.
The range is equipped with hermetic rotary Scroll compressors, ozone-friendly refrigerant R410A, axial-flow fans, shell and tube heat exchanger, full-aluminum air coils (chillers) or traditional copper tubes with aluminum fins (heat pumps) and electronic expansion valve.
Maximum Reliability
Unit with multi-circuit chilling section (two to four, depending on the size) designed to ensure maximum efficiency both at full load and part loads, assuring uninterrupted service in the event one of the two circuits fails.
The number of compressors also ensures a precise multi-step management of the cooling and heating capacity provided by each unit.
V-Shaped coil geometry
Open angle v-shaped coils achieve the maximum efficiency at all conditions. A specific design of the condensing modules allow a reduction in both unit footprint as well as clearances, thus facilitating service and maintenance procedures.
The structure is also designed to allow the easiest access to all the components in order to simplify maintenance work.
Full-aluminum coil
The cooling only version is equipped as standard with fullaluminum coils. This solution allows a reduction of the refrigerant volume compared with conventional copper-aluminum coils, also reducing the overall weight of the unit.
The bigger internal heat transfers to flow area ratio, as well as the reduced air shadow of the tubes, allows more efficient condensation, increasing the unit performance. All-aluminum micro-channel heat exchangers offer 3.5 times higher corrosion resistance than conventional coils.
The all-aluminum construction eliminates the formation of galvanic currents between aluminum and copper that are responsible for corrosion in saline or corrosive atmospheres.
Innovative fan management system
Climaveneta has designed a new system to manage the condensing fans with a complete new structure of the ventilation section (patent pending).
This ensures outstanding performance in terms of efficiency in all the operating conditions, thanks to: elimination of the reciprocal dependency on adjacent circuits ability to manage independent defrost cycles at different times in different circuits a more accurate fan speed management and, consequently, a lower power consumption.
Heat Pumps at -12°C outdoor temperature
NECS-N and NECS-NR heat pump models host several leading edge implementations, focused on efficiency and extended operation in winter mode, even with harsh outdoor conditions.
Heat pumps can in fact be equipped with the LT low temperature option. This includes a specific regulation which activates sufficient refrigerant injection, allowing operation to -10°C for the SL versions and -12°C for the CA versions.
Extended operation limits in chiller mode
An advanced fan speed management as well as the adoption of electronic expansion valves on all units, allows the new NECS to extend the operating conditions even with external temperature seasonal limits.
NECS can in fact achieve up to +46°C outdoor temperature, as well as up to -12°C of leaving water temperature. This is the reason why NECS can meet the most demanding project requirements, for comfort applications as well as for industrial processes.
Advantages
The technological choice designed to provide the maximum overall quality and the use of the most innovative technologies make the new NECS a range of units able to ensure maximum energy efficiency, easy to install thanks to its compact size, versatile and able to integrate with all Climaveneta´s monitoring systems.
