Daikin EWAQ320E-XL [2/34] Certifications
FEATURES AND BENEFITS
Low operating cost and extended operating life
This chiller range is 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 profita
bility,
effectiveness and economical management.
The chillers feature a high efficiency scroll compressor
s, large condenser coil surface area for maximum heat transfer and low discharge
pressure, advanced technology condenser fans and a 'plate to plate' evaporator with low refrigerant pressure drops.
Low operating sound levels Very low sound levels both at fu
ll load and part load conditions are achieved by the latest
compressor design and by a unique new fan that moves large volume of air at exceptionally low sound levels and by the virtual
ly
vibration-free operation.
Outstanding reliability
The chillers have
two truly independent refrigerant circuits, in order to assure maximum safety for any
maintenance, whether planned or not. They are equipped with hermetic orbiting scroll compressor complete with motor
over-temperature and over-current devices and protecti
on against excessive gas discharge temperature, a proactive control logic and
are full factory-run-tested to optimized trouble-free operation.
Superior control logic
The new MicroTech III controller provides an easy to use control environmental. The contro
l logic is
designed to provide maximum efficiency, to continue operation in unusual operating conditions and to provide a history of uni
t
operation. One of the greatest benefits is the easy interface with LonWorks, Bacnet, Ethernet TCP/IP or Modbus communications.
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:
HIGH EFFICIENCY
6 sizes to cover a range 178 up to 336 kW with an EER up to 3.11 and an ESEER up to 4.31 (data referred to Standard Noise).
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 power input for fans.
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 = Air inlet condenser temperature.
Sound configurations Standard, low and reduced sound configurations available as follows:
STANDARD SOUND
Condenser fan rotating at 900 rpm, rubber antivibration under compressor
LOW SOUND
Condenser fan rotating at 900 rpm, rubber antivibration under compressor, compressor sound enclosure.
REDUCED SOUND
Condenser fan rotating at 705 rpm, rubber antivibration under compressor, compressor sound enclosure.
