PROJECT
Daikin supplied R-32 EWAT-B- chillers in a project involving an office building in Bangalore, India. The units were installed to provide the HVAC system with the necessary chilled water to air handling units (AHU) installed in the Air Conditioning system, to meet the comfort needs of the occupants of an office building.

CHALLENGE & SOLUTIONS
The EWAT-B Series has been chosen to meet the sustainability goals set for the building. That means low GWP and high energy efficiency – then low direct and indirect CO2 emissions of the HVAC system – were the main reasons for this choice. Other than featuring low GWP and being highly energy efficient by design, the units installed also feature Dynamic Condensing Pressure Management, which allows the chiller controller to adjust the condensing pressure set point, minimizing the overall chiller power input. That not only will ensure low operating costs but will also help save on energy and resources and will ensure outstanding durability.
Besides that, the whole installation was designed to optimize energy use in the building. In this context, the role of the Daikin iCM controller, with superior control logic and connectivity to the Daikin cloud monitoring platform Daikin on Site, was vital, as it allows to monitor performance, take actions constantly getting the best energy efficiency levels, and schedule preventive maintenance to ensure absolute reliability.
Low noise was another relevant aspect of this project, ensuring that occupants in the office building have the best possible environment around them. In this case, it was requested to have the possibility to further reduce the default noise threshold by setting time bands when building managers can reduce fan rotation speed.
