Daikin EWWQ170G-SS [2/41] Certifications
FEATURES AND BENEFITS
Low operating cost and extended operating life The water cooled ranges are the result of careful design, aimed to
optimize the energy efficiency of the chillers, with the objective of bringing down operating costs and improving installation profitability,
effectiveness and economical management.
Flexibility The water cooled series meets all the possible request in terms of plant needs for comfort and process applications. The
units are available for chilled water production and for hot water production reversing on water side. There is also a condenserless
version. Partial recover version and hydronic version, with low or high pump head, are available on request.
Wide capacity range The water cooled series covers a
wide range of cooling capacities from 100 KW up to 700 kW. The
introduction of the new 60 HP scroll compressor allows to reach
very high capacity in the minimum space.
Wide operating range The extended operating range
allows the unit to work in a very wide range of water
temperatures. The electronic expansion valve (mounted as
standard) guarantees a fine control of the refrigerant flow even at
low condensing temperatures.
Compact Design The innovative design makes the unit easy to carry and position within technical room occupying the minimum
footprint. The Modular conception allows to position one unit upon the other reaching the highest kW/m2 ratio on the market.
Plug & play installation The units is conceived in order to be connected quickly to the plant. Victaulic connection are available
as option.
Superior control logic The unit controller provides an easy to use control environmental. The control logic is designed to
provide maximum efficiency, to continue operation in unusual operating conditions and to provide a history of unit operation. One of the
greatest benefits is the easy interface with LonWorks, Bacnet, Ethernet TCP/IP or Modbus communications. Master/Slave control is
available as standard.
Code requirements – Safety and observant of laws/directives Units are designed and manufactured in
accordance with applicable selections of the following:
Construction of pressure vessel
Machinery Directive
Low Voltage
Electromagnetic Compatibility
Electrical & Safety codes
Manufacturing Quality Stds
97/23/EC (PED)
2006/42/EC
2006/95/EC
2004/108/EC
EN 60204–1 / EN 60335-2-40
UNI – EN ISO 9001:2004
Certifications Units are CE marked, complying with European directives in force, concerning manufacturing and safety. On request
units can be produced complying with laws in force in non European countries (ASME, GOST, etc.), and with other applications, such as
naval (RINA, etc.).
Versions This range is available in one version:
STANDARD EFFICIENCY
24 sizes to cover a range 92 up to 722 kW with an EER up to 4.60 and an ESEER up to 5.55.
The EER (Energy Efficiency Ratio) is the ratio of the Cooling Capacity to the Power Input of the unit. The Power Input includes: the
power input for operation of the compressor, the power input of all control and safety devices.
The ESEER (European Seasonal Energy Efficiency Ratio) is a weighed formula enabling to take into account the variation of EER with the
load rate and the variation of air inlet condenser temperature.
ESEER = A x EER100% + B x EER75% + C x EER50% + D x EER25%
K = Coefficient; T = Water inlet condenser temperature.
