HVAC

Hansa Energy Solutions had been retrofitting conventional buildings with energy efficient HVAC. HVAC efficiency include detailed engineering and a holistic approach. All interactive effects need to be taken care ie. energy efficient measures in one area could lead to increase the energy consumptions in other connected areas. We ensures that project is implemented with minimal return over investments with a holistical approach.

Hansa Energy Solutions is tied up with Danfoss brand for variable speed drives and have own panel fabrication facility to build the control panels. Large chunk of energy in any industry is swallowed by the HVAC requirements especially in middle east where the sun bestow its energy in fullest.

Hence it is necessary to ensure that the energy consumed for HVAC is optimized and efficient . HVAC system are broadly classified as following:

• Centralized system - District Cooling ,Centralized chiller plant etc
• Ducted Split – VRF,VAM etc
• Normal Split/Window ACs

Centralized chilled water system and district cooling system is gaining importance due to better COP & EER. However from our experience it has been noted that due to over engineering/design flows there are many areas where energy consumption can be plugged .DELTA T correction in district cooling plant is one such area . Lower delta T will lead to higher flow per Ton and hence increase the energy consumption.

Adiabatic Cooling System

Adiabatic cooling systems function similarly to dry cooling systems, but with the incorporation of pre-cooling pads, running water over pre-cooling pads and drawing air through the pads depresses the dry bulb of the incoming air. The depressed dry bulb allows for greater system heat rejection.

Key Benefits

• Low process temperatures
• Saves more than 80% on annual water compared to cooling towers
• Up to 40% increased capacity compared to dry cooling (air temperatures approaching wet bulb temperature)
• Reduced energy consumption.
• Operational safety: no water recirculation, no stagnant water, no aerosol generation, no water carry-over.

Danfoss Drives for your applications

A variable frequency drive can vary the power supplied to match the energy requirement of the driven equipment, and this is how it saves energy or optimizes energy consumption.

The drive can dramatically reduce energy consumption, fuel savings of 40% are common. It reduces NOx emissions and CO2 footprint of the systems.

Danfoss is global market leader in VFDs, Advance system with high reliability. Ensure high quality, available with integrated harmonic mitigation and meet EMC requirements. It optimizes energy use and meet performance standards.
