Reduced energy consumption and CO2 emissions achieved by new Daikin free cooling chiller range
Story
Daikin Europe N.V. announces new air-cooled chiller range that uses “free cooling” from cool outdoor air30C for examplefor greater energy savings and reduced operating costs.
Free cooling chillers incorporate an additional free cooling section, which cools the building water loop directly with the outside ambient air, thereby reducing compressor cooling load, reducing energy consumption and CO2 emissions and considerably decreasing operating costs during the cold season.
Free cooling takes advantage of the temperature difference between the outside air and return water, cooling the water before returning it at a lower temperature to be chilled. When outside temperatures are cold enough: 30C or lower, depending on the chiller model, the compressors are fully shut down and cooling is achieved on a practically free basis. Furthermore, cutting compressor usage also extends the chiller’s operating life and minimises overall installation costs.
The new range comprises 11 sizes with capacities from 600 kW to 1,565 kW, all available in three sound levels and in standard as well as glycol-free versions (EWAD~CF and EWAD~CG respectively). A wide range of operating conditions is supported and units can operate in ambient temperatures from -18°C to 40°C, and supply leaving water temperatures from -8°C to 15°C. A new MicroTech III controller provides easy access to system parameters and integration with most popular building management systems is supported.
The introduction of the new free cooling range to its EWAD~C chiller portfolio (EWAD~C-, EWAD~CZ , EWAD~CF and EWAD~CG), enables Daikin Europe to make good its commitment to supply the market with superior solutions for diverse applications requiring the highest levels of energy efficiency, savings and comfort.
