Daikin EWAT290B-SRA1 [2/62] Features and benefits

FEATURES AND BENEFITS

2/62

Low operating cost.

The new Daikin BLUEVOLUTION chiller series (EWAT-B) is the result of careful design aimed to optimize the

energy efficiency and thus the total life cycle cost of the chiller, with reduced operating cost thanks to outstanding

performances and reliability.

The chillers feature high efficiency scroll compressor arranged in tandem or trio configuration on each refrigerant

circuit, optimized condensing section with advanced technology condensing fans and plates evaporator with low

refrigerant content and reduced pressure drops.

Low environmental impact.

Latest revision of F-GAS, entered into force in 2015, set up a phase down program for traditional HFC’s

refrigerants. In 2018 first significant reduction step will be introduced (37%) and in 2030 the reduction (calculated

in equivalent CO2 tons) will need to achieve almost 80%.

The new Daikin BLUEVOLUTION chillers uses R-32 refrigerant to reduce drastically the carbon footprint of the

unit. The selection of R-32 (chemical name difluoromethane) minimises the global warming impact of scroll

compressor chillers thanks to the lower Global Warming Potential in combination with high-energy efficiency.

The Global Warming Potential of R-32 is 675, which is only one third of the commonly used refrigerant R-410A.

Thanks to the lower flammability classification (R-32 refrigerant is classified A2L in ISO817), it can be safely used

in many applications including chilled water systems. Being a single component refrigerant, R-32 is also easier to

recycle and reuse, that is another environmental plus in its favour.

Daikin has a long history of continuous reduction of the environmental impact of cooling, heating and refrigeration,

having a unique expertise that comes from manufacturing both refrigerants and equipment. This position is one

of the results of company's corporate philosophy to "Be a Company that Leads in Applying Environmentally

Friendly Practices".

Regarding refrigerant choice, Daikin has expertise in using fluorinated (HFC, HFO) as well as non-fluorinated

gases (ammonia, carbon dioxide, hydrocarbons), because the company believes in diversity of refrigerant choice

to allow the best suited solution to be used in each application.
