Daikin brings inverter control to small chillers

Chiller, Daikin, inverter control, SpaceAir

All the advantages of inverter control have been brought to the small chiller market with the launch by Daikin of the R410A EWA/YQ~BA range. Part-load efficiency is improved, enabling a seasonal energy-efficiency rating (ESEER) of up to 4.5 to be achieved. The integrated inverter also reduces start-up current and achieves a power factor of at least 0.95.

The units are available in cooling-only and heat-pump versions. Cooling capacities are from 17 to 75 kW in five sizes with one or two circuits.

The basic hydraulic module can be equipped with a optional factory-mounted pump or high ESP pump. No buffer tank is required. The units include a digital controller and support for an additional remote controller.
