Air-cooled chillers

Daikin describes its EWAD-TZ B range of air-cooled chillers as ‘pushing the boundaries of design to meet the challenges of green-building efficiencies and new legislation though the application of advanced technologies, resulting in a host of new features’. The refrigerant is R134a.

These chillers area available as single or twin-circuit units with cooling capacities from 170 to 700 kW. The screw compressor has integrated inverter technology combined with a technology that enables them to modify their own geometry, varying the condenser pressure charge to maintain the highest compression efficiency.

The advanced design of the heat exchanger delivers a high heat-transfer coefficient while minimising pressure drops. There are three levels of efficiency to choice from, offering the best compromise between efficiency and price.

The micro-channel condenser coil uses 30% less refrigerant charge.

All components are sealed in an insulated housing with compact electrical panel. The refrigerant cooling system keeps the electrical circuits at a constant temperature, extending the life and reliability of the system.
