2 Specification text
Unit construction: DAIKIN inverter controlled mini chiller with extremely compact, modular and weatherproof heat pump design for outdoor application IP 24 that meets ISO 9001 standards. The unit is ready for connection and has been designed for air conditioning as well as process cooling applications. The use of state-of-the-art technologies and high quality materials ensures efficiency, reliability and extended service life. Each DAIKIN chiller is subjected to a factory-side test run under standard conditions lasting several hours.
Casing / Colour: Powder coated, galvanised steel plate. Fully factory assembled on a base frame. Ivory white / Munsell code 5Y7.5/1
Number of refrigeration cycles: Unit size 005 - 007 single circuit.
Compressor: Fully hermetical inverter controlled swing compressor optimised for R410A, high performance, very smooth operation, low noise, highly efficient. On the suction side it is protected against water hammer by a large accumulator. The refrigerant compressor is equipped with an overcurrent relay and a thermal protection.
Condenser: Each refrigeration cycle has a high-performance Cu/AL heat exchanger. Consisting of internally drawn Cu pipe (Hi -X) guaranteeing excellent heat transmission and optimal oil transportation. Integrated subcooler for increased performance. Increased heat transmission surface with continuously laminated wafer fins results in reduced sound levels and compact dimensions. An polyacryl coating permanently protects the fins from corrosion thereby extending the field of application of this device.
Fans:Axial fans with thermal-protection drive motor 230 V/50 Hz. For condenser pressure control the fan is inverter controlled. The motor is statically and dynamically balanced and the bearing is realized in a way that vibration is absorbed. A close meshed fan grille protects the fan against external forces. Air suction is realized via the condenser.
Refrigeration cycle: Consists of Cu tube with all necessary cooling fittings such as: 4-port valve, service valves, filter, muffler, EEV, FL seperator. The refrigeration cycle is subject to factory pressure and leak testing, is cleaned, dried, evacuated and supplied with the R410A safety refrigerant and oil charged ready for operation.
Evaporator: R410A optimised DX counter flow plate heat exchanger made of stainless steel, plates brazed gastight with copper, for water and glycol mixtures. For optimum capacity of the complete heat transmission surface a special refrigerant distribution system has been incorporated into each plate duct. This further increases the efficiency and provides a stable control behavior in the heat exchanger. In order to prevent loss of heat the plate heat exchanger has a diffusion-proof heat insulation. To prevent freezing damage when ambient temperature is low the plate heat exchanger is equipped with a heater.
Hydraulic Module: The cooler tubes are made of corrosion-resistant brass and the heat exchanger is equipped with a strainer and an electromechanical flow controller. The unit also comes with all hydronic components needed for operation. This includes a circulation pump, expansion vessel, manometer, shut-off valves, safety valve, purge, charge and drainage valve, maintenance connections and compensation valve.
Switching and control device: Micro computer control with integrated self diagnosis. Complete electric wiring with terminal blocks for feed-in, main switch and connection to external control panel.

2 Specification text
The connection wire for the external control panel (2x 0,75–1 mmm2) has to be ordered separately. The maximum distance is 500 m.
External DDC control panel: The units are supplied with a digital controller that allows for a user friendly set-up, operation and maintenance of the unit.
The electronics support for example the following functions:
On/OffCooling/heating (heat pump only) Continuous condenser pressure control „Silent Mode“ night setback Allocation of the target value and the switching hysteresis Automatic sliding target value shift Cold water flow control Timer / Date functionality Schedule timer Error code retrieval

semi-anachoic room)2 dB(A) = A-weighted sound pressure level (A-scale
according to IEC)3 Reference acoustic pressure 0dB = 20μPa4 If sound is measured under actual installation
conditions, the measured value will be higher due toenvironmental noise and sound reflections.
