11.Guide specifications SPCA 001-010RSB The supply, transport to jobsite, installation, commissioning and start up of an air cooled water chiller with the following technical characteristics. The unit shall be factory assembled, charged with R407C refrigerant and factory tested. The capacity of the unit shall be no less than: kW Ambient air temperature (DB) Entering water temperature Leaving water temperature ÆC ÆC ÆC The unit shall operate unhindered within 6 to 15ÆC water outlet temperature, 3.5 to 7ÆC water temperature difference and 5 up to 45ÆC ambient air temperature. The structural requirements shall be the following: UNIT HOUSING The unit housing shall be fabricated from heavy gauge galvanized steel sheets, formed to ensure maximum rigidity that shall guarantee and preserve the unit operation during the years. All metal parts after fabrication shall be degreased phosphatized, and electrostatically powder coated with epoxy- polyester RAL 9002 coating of a thickness of 60 - 70 Ì. The corrosion resistance treatment must successfully withstand a salt spray test of 500 hours, according to ASTM B- 117. All components shall be assembled exclusively together using bolts, without welding. The unit shall have removable access panels, designed in such a manner as to permit easy access to internal compartments only by authorized personnel. COMPRESSOR Shall be of the hermetic scroll type, with low noise and vibration levels, specially optimized for use with R407c refrigerant. It shall be equipped with a crank case electrical heater, to separate refrigerant and oil when the unit is not operating. It shall also include internal protection against overloading or electrical spikes. The compressor shall be mounted on special anti vibration rubber mounts to absorb and eliminate any vibration that can be generated from the unit base. HYDRAULIC KIT The unit shall be equipped with a complete hydraulic kit, comprising of a circulating pump, buffer and expansion tank, automatic fill / make up water valve with manometer, safety valve, air vent, water filter and differential water pressure switch. AIR HEAT EXCHANGER The air hear exchanger shall be manufactured from seamless copper tubes having an outside diameter of 9.52mm (3/8'') of high quality according to ASTM B 280. The tubes shall be internally grooved to achieve optimized heat transfer between refrigerant and tube. The fins shall be manufactured from aluminium. The fins shall be continuous across the heat exchanger and the fin surface shall be waffle formed and louvered so as to increase the fin rigidity and heat transfer. The combination of internally grooved copper tubing and louvered fins must result in a heat transfer performance 30% superior to that of a conventional coil. The assembly of the finned pack shall be achieved by mechanical expansion in such a way as to form a perfect mechanical bond with the fins. For this purpose, the fin holes shall have a peripheral extrusion (collar). WATER HEAT EXCHANGER The water heat exchanger shall be of the plate heat exchanger type, selected from world-class manufacturers and made of stainless steel plates (AISI 3161.4401) specially formed to achieve optimized heat transfer. The plates shall be assembled by means of an automatic brazing process, under vaccum. CONDENSER FANS The unit shall be equipped with axial type fans, single phase, and 6 poles, internally protected against potential overheating, noiseless and suitable for outdoor installation. The design of the blades and inlet cones shall be aerodynamic, and the fan motor assembly shall be perfectly statically and dinamically balanced allowing a completely vibration free operation. The fan motor assembly shall have a protective grid against accidental contact with moving parts according to ISO. The fan motor shall be of the external rotor type with permanently lubricated bearings that do not require servicing. The motor shall be aerodynamically shaped so as not to interfere with the airflow. The unit shall be equipped with a continuous linear fan speed regulation control according to coil temperature. CONTROL SYSTEM WITH MICROPROCESSOR CONTROLLER The control system shall possess a sophisticated controller that shall constantly monitor all machine parameters and particullarly manage among others: ñ Automatic compressor control function through return water temperature. ñ Continuous fan speed control based on coil heat exchanger temperature.
