5 ANTIFREEZE MIXTURES Machines can work with antifreeze mixtures although not necessary, because the machines do not accept outlet temperature of the liquid cooled below 4 C, the use of glycol mixture is a generic antifreeze protection, for machines not in operation during the winter season. STORING TEMPERATURE If the machine is not installed on receipt and is stored for a long time, store it in a protected place, at temperatures ranging between -30 C and 50 C in absence of superficial condensation and direct sun light.

13 ELECTRIC DATA MAXIMUM ELECTRIC ABSORPTION CALCULATION This chapter is showing the maximum electrical absorption calculation of unit (A), corresponding to extreme working conditions. The involved components are the following: Compressors electric motor Condensers fans electric motors Water pumps electric motors (if present) The electrical data of the various components are indicated in the relative technical data sheets. EXAMPLE n.1: Calculation for UNICO TURBO FL 490 T2: MAXIMUM ELECTRIC ABSORPTION Compressors A 278,0 + Condenser fans A 31,2 = Maximum electric absorption A 309,2 EXAMPLE n.2: Calculation for UNICO TURBO FL 490 T2 with GPUs-B pumping group: MAXIMUM ELECTRIC ABSORPTION Compressors A 278,0 + Condenser fans A 31,2 + Water pump A 10,1 = Maximum electric absorption A 319,3 IMPORTANT For water pumps and condenser fans, the current nominal values have been considered equal to the plate value. Therefore the nominal current and the plate current are the same. In fact, the real absorbed current is normally lower than the plate value. These values depend on the unit working conditions and on the control type of the plant. RC GROUP S.p.A. T_UNCTRBFL_1012_GB R134a 13

14 MICROPROCESSOR CONTROL SYSTEM The microprocessor controls the machine guaranteeing on the one hand a precise and punctual temperature regulation, on the other hand integrating the safety functions relative to all fluid-dynamic circuits. The microprocessor controls the outlet temperatures of the chilled water through two set parameters, xk1 e xk2, as outlet temperatures from the evaporators, with possible remote commutation through voltage free contact. In any case, the microprocessor will modulate the electric input to the compressors motors to guarantee the maximum temperature precision in respect of the working range allowed by the centrifugal compressors. For any working condition, the control will cleverly manage the number of compressors to be activated in a combined optics of safety and energy saving. The system includes: Compact controller for DIN rail mounting 24Vac 50/60Hz 32-bit microprocessor 2 +2 MB flash memory (retains data without power) and memory RAM 512kB Integrated Data logger function for the recording of events and alarms.

21 OPTIONAL ACCESSORIES - LNO KIT This optional is available as accessory to obtain a machine noise reduction. The versions equipped with LNO KIT having the following characteristics: Set of the working parameters. Specific settings for the control of ventilation Sound insulation of the compressor casing Isolation of the suction. The LNO KIT allow 3 different type of set: LNO KIT 100% No air flow reduction. Isolation of the delivery pipe, for the stretch from the flange on the compressor to the manifold. LNO KIT 85% Reduction of air flow to 85% of the nominal value reported in Technical Data Isolation of the delivery pipe, for the stretch from the flange on the compressor to the manifold. LNO KIT 70% Reduction of air flow to 70% of the nominal value reported in Technical Data Isolation of the delivery pipe, for the stretch from the flange on the compressor to the manifold. SUPER SILENCED VERSION Special versions may still be required to meet more stringent requirements on noise, not achievable with the devices described above. RC GROUP reserves the right to assess the feasibility of machines with capacity condenser sections, characterized by low air speeds. WARNING Consider that a condenser coil air flow reduction induce a minor cooling capacity of the machine and a major energy consumption of the compressor. To obtain the effective working conditions of cooling capacity and noise reduction for unit equipped with LNO KIT, please refer to the electronic selection catalogue RC WORLD. RC GROUP S.p.A.
