When Striving For Highest Efficiency
Today's office buildings, hotels, large shopping and leisure complexes, all the most prestigious projects require leading edge solutions to meet extremely demanding challenges:
Precise Attention To Comfort And Noise Emission
To guarantee ideal temperature, humidity and air quality go together with the need to reduce noise emissions and vibrations. This is a decisive aspect in order to ensure adequate comfort, as well as to comply with noise emission regulations.
Very Strict Energy Efficiency And Sustainabilt Requirements
Reduced initial investment and running costs, compliance with increasingly strict energy consumption and environmental impact regulations, are becoming more and more crucial factors not only for real estate valuation, but also in deciding if the project should proceed.
Infrastructure And Technical Space Optimization
The real estate value, especially with expensive, prestigious investment in urban environments may be
determined also by the quality of the electrical system installed. Hence, choices that do not overload electrical infrastructure are more and more desirable.
Low In Rush Current
A further benefit is the very low inrush current, obtained thanks to the characteristics of the compressor and to the “inverter” starting. This is a crucial factor, as it allows a more favourable selection of the protection devices to be placed on the power supply between transformer and unit.
Simplified Logistics
reduced noise emission, TECS2 sound power and pressure are the lowest on the market, without peaks in any of the sound frequency spectrum. Vibrations are dramatically reduced as well, with considerable advantages in terms of transmission to the building. Turbocor compressors feature an extremely advantageous capacity / weight ratio. The considerable weight reduction allows simplified site operations.
Extremely Silent Operation
Thanks to the adoption of the centrifugal compressor with magnetic levitation, and, in air source units, of fans with
Unbeatable Efficiency At Part Load
At partial load, TECS2 units are far more efficient than traditional scroll/screw units, with ESEER values up to 60% higher. Running cost savings are evident and consistent, especially when all year round operation is required.
Tecnological Choises
Efficiency, silent operation and reliability. But also compact dimensions and reduced weight. These are the main features that make TECS units the best result of Climaveneta’s know-how. Advantages that result from technological choices, involving each aspect of these units.
Centrifugal Compressor With Magnetic Levitation
This is a miniaturized, highly innovative compressor, with magnetic levitation device and digital control of the rotor’s speed. The efficiencies achieved are far superior to those with traditional volumetric compressors. Inverter controls with inlet guide vanes extend the compressor’s operational limit: building requirements are precisely met, even at very low conditions. A solution that, besides the reduction of weight and dimensions with respect to traditional compressors, permits the compressor to operate completely without oil allowing an improvement of its performance, through the heat exchange process. Vibrations are virtually eliminated together with possible jolts due to inrush current in the start up phase: the
Flooded Evaporator
The technology of flooded evaporator, further enhanced the absence of oil in the refrigerant circuits, realises a substantial increase of cooling capacity and an optimization in the compressor’s operational mode. The unit’s overall efficiency further increases thanks to: Compression ratio reduction thanks to a smaller approach Theoretic absence of refrigerant superheat at the compressor’s suction stage Minimization of refrigerant pressure drop on the evaporator’s shell side Optimization of the exchange surfaces, also at part loads, thanks to the complete control of the refrigerant level in all operating conditions. To comply with the security requirements of the “F-gas Regulation” (CE 842//2006), factory calibrated leak detection systems are available upon request.
EC FANS
On TECS2 units, the technology of EC electronic switching fans is introduced, as standard on SL-CA-E versions and optional on the other models. The superior energy efficiency of the DC brushless motor further improves the chiller’s performance, that reaches the highest ESEER level in the market. More advantages are low inrush current and the ability to continuously modulate the rotational speed with an immediate gain in both silence and energy consumption.
Electronic VALVE
The electronic valve is adopted to grant the ideal operation of the evaporator in all conditions. In the air cooled unit the control is made with a precise measurement of the subcooling in the condenser coil. The fast processing of the acquired data allow a quick, fluctuation-free regulation, and therefore a highly accurate adjustment to the swings of load and ambient conditions.
Advanced W3000 Touch Control System
The brand-new W3000 touch control system features friendly user interface, excellent control, strong expansion ability and compatibility.
Electronic VALVE
The touch screen is embedded in the unit for convenient operation and well protection. The automatic control by the computer realizes unattended operation. TFT LCD touch screen can display data and parameter adjustment in various languages and menus. According to the tradition of Climaveneta, the status and parameters of the compressor are visually displayed individually to make sure the operating status clear at a glance.
Unit Control and Operation Management
The advanced microcomputer intelligent control system of W3000 contains specially designed control algorithm of Climaveneta. It highlights the energy efficiency and reliability of the unit. The balanced running time of FIFO compressor prolongs the life of machine. The automatic adjustment of the output load makes the machine more energy saving.
