﻿Daikin brings inverter control to small chillers
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.
