7 2 Specification text Chillers R-34A EWWD-N 3 Unit construction: Compact modular design water-cooled chiller for indoor installation IP20 that meets ISO 900 quality standards. Series EWWD unit has been designed for air conditioning as well as process cooling applications and meets PED conformity. 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. 2 Casing / Colour: Powder coated, galvanised steel plate. Fully factory assembled on a base frame. Ivory white / Munsell code 5Y7.5/ Number of refrigeration cycles: Size single cycle, double cycle. Fully independent refrigeration cycles guarantee for a high level of system reliability. Compressor: New continuous, smooth, semi-hermetic DAIKIN single screw compressor developed and optimised for the use of the R34a refrigerant. The sophisticated compressor concept eliminates the radial and axial bearing loads by balancing the pressure on the main rotor and the main rotor bearing. All bearings are designed to last for the compressor's life-cycle of more than 00,000 operating hours. The single screw design as well as main rotor and 2 star rotors allow for a double compression of 2 compressions per rotation. The main screw is directly driven by a powerful 2 pole electric motor and cooled by refrigerant injection. Due to the double compression the compressor achieves up to compressions per minute which reduces noise emission and vibration to a minimum. The asymmetric /6 gear results in constant performance even after several years of compressor operation and prevents additional pulsating compression gases. The compressor provides a double wall casing with silencer function, a wear resistant star rotor consisting of composite material, an axial slide for continuos performance control, an integrated oil separator with muffler function, high pressure oil lubrication (no oil pump required), oil sump heater, oil-level gauge, check, hot gas stop, service s, suction gas filter, Klixon embedded in the motor winding, star or delta start-up. The high-efficiency design is optimised for the refrigerant and system and provides maximum EER values and operation reliability. System and service costs are kept at a minimum. Condenser: Type-tested tube bundle heat exchanger, optimised for R34a. The refrigerant flows around the tubes, the heat transfer medium through the tubes. By using an integrally finned structured high capacity Cu tube that has been rolled gastight into the pipe beds, device size, weight and refrigerant capacity could be reduced drastically. Integrated subcooler for further increased performance. Casing consists of steel and is provided with removable end caps. Victaulic water connections. The water pressure may not exceed the maximum permissible operating pressure of 0 bar! Evaporator: R-34a 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 (Equalancer System ) has been incorporated into each duct plate. This further increases the efficiency by 6% 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. The water pressure may not exceed the maximum permissible operating pressure of 0 bar! Flow controller and strainer are standard. Piping: Consists of Cu tube with all necessary cooling fittings such as: Service s, filter-drier, inspection glass with moisture indicator, solenoid and TEV or EEV. The refrigeration cycle is subject to factory pressure and leak testing, is cleaned, dried, evacuated and supplied with the R34a safety refrigerant and oil charged ready for operation.

32 Chillers R-34A EWWD-N Installation - Fixation and foundation of units Section X-X Ditch Foundation is built on the ground Foundation is built on concrete floor Fix anchor bolts into the concrete foundation. The concrete foundation should be higher than the floor level by approximately 00 mm for ease of plumbing work and better drain. Further, strength of the floor should be sufficient to support the weight of concrete foundation and unit. Be certain that the foundation surface is even and flat. NOTES:. The measurement tabulated is based on the fact the base is made in the ground or on a concrete floor. In case the base is made on a rigid concrete floor, it is possible to include thickness of concrete floor in that of the base. 2. In case a base is made on concrete floor, be sure to provide a ditch as shown. It is important to extract drainage regardless of wether a base is made in the ground or on the concrete floor (Ditch Sewerage). 3. Ingredient ratio of the concrete is cement:, sand: 2, gravel: 3, which is standard and insert iron bars of J0 at every interval of 300 mm. The edge of the concrete base should be planed.
