Daikin offers different types of free cooling, including glycol free systems, to meet the needs of critical applications like data centres. It also uses sophisticated plant management systems supported by AI to keep chillers operating close to their optimal performance level and balances total capacity with actual load. This improves energy savings by as much as 20% compared with traditional chiller sequencing control by BMS.
Daikin has also extended other aspects of its products and services to meet evolving end user requirements and now offers two ranges of air-cooled chillers specifically for data centres.
Its chiller range includes screw compressor units equipped with variable frequency drives (VFD) which are designed and manufactured in-house and mounted onto the compressor for better reliability and efficiency.
This allows precise modulation of cooling loads with capacities up to 2150 kW and scroll compressor chillers with capacities up to 1344 kW which are ideally suited to a range of applications from refurbishment projects to major new developments.
Daikin chillers deliver up to +30°C supply water temperature, and can operate in a wide band of outside temperature conditions between –35°C and +55°C. This flexibility is particularly valued by large data centre operators juggling with ever denser concentrations of servers and ancillary equipment.
Daikin also offers the Pro-W; high-efficiency computer room air handling (CRAH) solutions, manufactured in both the UK and Italy. The Pro-W range offers cooling capacities from 200kW to 700kW making them ideal for even the very largest data centres.
These capacities are achieved using just four core unit sizes, which means the company can use a dedicated range of standardised components, including built-in EC fans and cooling coils, to guarantee manufactured quality and short production lead times.
Despite their large cooling capacities, the Daikin products are compact which allows them to be fitted in restricted areas. The company also offers a range of control options specifically tailored for data centres to ensure the chiller plant delivers 24/7 cooling operating in the right mode by adjusting continually to real time conditions. The chillers also come with a choice of refrigerant to further meet environmental concerns.
Daikin provides comprehensive after-sales support including access to its remote monitoring ‘Daikin On Site’ (DOS) service so any performance or safety risks can be flagged up to keep the system running as it was intended.
DOS captures live operational data from the data centre and combines it with statistical predictions using trend analysis. This allows the service team to develop a preventative maintenance schedule to ensure the efficiency and reliability of the critical equipment, avoiding costly downtime and major repairs.
