6 2 Specification text Unit construction Special compact, upright design air-cooled chiller for indoor installation with duct connection (air outlet) manufactured according to the ISO 900 quality standard. The ready-to-connect range has been designed for both air conditioning and process cooling applications. The use of state-of-the-art technologies and high quality materials ensures efficiency, reliability and an extended service life. Each DAIKIN chiller is subjected to many hours of test runs in the factory allowing for standard requirements. 2 Casing / Colour Powder coated, galvanised steel plate. Fully factory assembled on a base frame. Colour ivory white (+/- RAL 7044) / Munsell code 5Y7.5/ Number of cooling circuits Size 5-0 single circuit. The refrigerant circuit has its own fully independent design thereby guaranteeing a high level of system reliability. Compressor R-407C optimised fully hermetically sealed DAIKIN scroll type compressor. As a design requirement, this compressor characteristically offers extremely smooth performance, efficiency and operational reliability. Each compressor is mounted in the unit with vibration isolation, with oil sump heating and fitted with a compressor motor overcurrent (Klixon). Condenser Cu/Alu high-performance design heat exchanger. Consisting of internally drawn helical Cu pipe (Hi -X) guaranteeing excellent heat transmission and optimal oil transport. Provided with a built-in subcooler to further improve performance. By increasing the heat transmission surface using continuous laminated honeycomb slotted flaps, a very low sound level is attained still with compact dimensions. A polyacryl coating permanently protects the flaps from corrosion thereby extending the field of application of this device. Fans Radial fan with blades bent forward, twin sided suction, statically and dynamically balanced. Size 5 with direct drive, size 8 and 0 with V-belt drive. Evaporator R-407C optimised DX counter flow plate heat exchanger made of stainless steel, plates brazed gastight with copper, for water and glycol mixtures. A special refrigerant distribution system has been incorporated into the plate duct for optimal capacity of the complete heat transmission surface. As well as an additional increase in efficiency, this is also responsible for stable control behaviour in the heat exchanger. The plate heat exchanger is heat-insulated to ensure it is diffusion-proof to prevent any heat loss. Piping Consisting of Cu pipe with all the necessary cooling fittings such as: High pressure and low pressure manometer, service valves, filter-driers, TEV with external pressure equalisation. The refrigerant circuit is subject to factory pressure and leak testing, is cleaned, dried, evacuated and supplied with the safety refrigerant R-407C and filled with oil ready for operation. The plate heat exchanger is cased with galvanised steel. Safety and control devices Each refrigerant circuit has the following safety devices: High- and low-pressure switch, hot gas temperature monitoring, thermal cut-out for compressor and fan motors, overload relay and frost protection. Each refrigerant circuit is fitted with the following control devices: Electronic temperature monitoring, phase-sequence relay, timing safety device and switch frequency limiter.

7 Switching and control device 2 In addition to the fully automated µ-chiller digital controller (manufactured by CARREL), the control cabinet manufactured in accordance with the valid EN directives (CE) contains all the required switching and control components such as: load, auxiliary and control cut-outs, transformers, control fuses, relay and auxiliary relay, sensors and µ-chiller digital controller. The electronics have an automatic restart after power failure and provide the following digital inputs and outputs hard-wired to terminals for incorporating the GLT: Digital inputs: Digital outputs: - Contactor - Collection fault message - Pump contact - General operating message - Remote ON / OFF - Operating message per compressor - Cold water pump drive µ-chiller digital controller The EUWAC-FZW units are fitted with a digital controller, which allows the user to configure, operate and service the unit in a user-friendly manner. The µ- Chiller digital controller consists of a numerical display, 4 control keys and 4 LEDs. The following functions are supported by the electronics, amongst other things: Condensation pressure control (winter control down to -0 C ambient temperature) Allocation of the set point and the desired switching hysteresis Cold water return controller Allocation of pump lead times / overrun times Allocation of service intervals Displaying the current operating parameter such as flow and return temperatures Recording operating hours (compressor / pump) Fault code query Password protection As an option this chiller can be fitted with an interface for integrating it into a Building Management System (BMS), which either supports the MODbus / J- bus or BACnet protocol. 8 Applied Systems Chillers

11 5 Control systems 5 Direct and user parameters The digital controller provides direct and user parameters. The direct parameters are important for the everyday usage of the unit, e.g. to adjust the temperature setpoint or to consult actual operational information. The user parameters on the contrary provide advanced features such as adjusting time delays or disabling the buzzer. Each parameter is defined by a code and a value. For example, the parameter used to select local or remote on/off control has code h7 and value or 0. User interface EUWAC5-0FZ The digital controller consists of a numeric display, four labelled keys which you can press an four LEDs providing extra user information. Digital controller comp x 00 PRG mute SEL clear Keys provided on the controller. Each key, except for the lower left key, combines two functions: m / k,o / i and b / c. The function carried out when the user presses one of these keys depends on the status of the controller and the unit at that specific moment. m Key, to enter the scroll list of user parameters, to confirm a parameter modification and to return to normal operation. LEDs provided on the controller: The controller provides five LEDs one of which, the left l LED, is not used. l LED, indicates the status of the compressor. The LED does not light up when the compressor is not active, blinks when the compressor cannot start up although extra load is requested (e.g. timer active) and lights up permanently when the compressor is active. k o Key, to de-activate the buzzer in the case of an alarm. Key, to scroll through the list of direct or user parameters or to raise a setting. b s LED, indicates that cooling mode is active. LED, indicates that the value on the numeric display should be multiplied by 00. n b c Key, to enter the scroll list of direct parameters or to switch between a parameter s code and its value. Key, to start the unit in cooling mode or to switch the unit off when cooling mode is active. Key, to scroll through the list of direct or user parameters or to lower a setting. Note: Temperature readout tolerance: ± C. Legibility of the numeric display may decrease in direct sunlight. 2 Applied Systems Chillers
