1. Evolution Daikin Chiller Range
New Daikin Products 2007

2. Daikin Chillers range
Important features: Price, efficiency, reliability
2 main sections can be distinguished: Aircooled units and watercooled units.
These ranges will be discussed more in detail, started from the aircooled range:

In the aircooled range, the nominal capacity of chiller units offered by daikin, is between 5 kW (minichiller) all the way up to kW. Mainly one of 2 refrigerants is used : R407C and R134a.
The R407c range is predominantly used for comfort cooling, while the higher efficiency R134a range is ideal for process or higher spec applications. Process applications require a certain amount of ensured cooling, even during a breakdown of chiller part.
Depending on the type, 1 chiller unit contains either a single, a dual circuits or a ternary refrigerant circuit, sharing a single evaporator. The amount of independent circuits, shown as different colors on the graph, indicate a reliability, (and a price difference), since every circuit contains at least one compressor, a condenser and an expansion valve (+ a filter, an oil seperator) .
Furthermore, the difference between

Some ranges at smaller capacities (up to 260 kW) are available in heat pump versions (Y in the name), the rest are cooling only chillers.

These compact systems use water (well water, city water, ...) for the cooling or heating process
Can be installed in a machine room, thus reduced noise
Used in home, commercial, office and industrial applications
Extra Information on each Series:
EWWP-KA: Single circuit for kw, dual circuit kW (single unit), 2 units (4 cirq) up to 141 kW and climbing up to 6 truly independent circuits (3 units) for a 200 kW unit. The control of the 3 units is common and the units operate as one single chiller.
Ewwd-MB: single cirquit kw, dual cirquit from
EWWD-DJ has change over from 165 kW-280kW and 2cirquit kW
BJ series: High efficiency, all the way (2X flooded): Good efficiency, but expensive solution, since 2 flooded heat exchanger, and high refrigerant volume.
Motivation for MB <--> DJ type: MB has plate heat exchanger condenser, while DJ has Shell and tube condenser: Thus MB allows faster and more precise control at fluctuating conditions, while DJ is more stable, needs less stringent water quality, but at somewhat higher cost (and slightly more refrigerant). Furthermore, the specs are very comparable. The market will descide which series will be continued.
