Improved to include the latest heat transfer surface design and the most advanced and efficient reciprocating compressors in the industry, the redesigned chillers exceed efficiency requirements. The McQuay air cooled water chillers are completely factory assembled, piped, wired and shipped in one piece, ready for installation. Each unit consists of compressors, insulated evaporator, condenser coils with independent subcooler circuits, multiple propeller type direct drive condenser fans with independent fan motors, heavy-gauge weatherproof casing and weatherproof electrical control centre containing all necessary and operating controls and motor starting equipment. Highly flexible design The units is available in 2 sizes covering a range from 0 to 110 nominal cooling with coolant temperature between +10 C and - C. Many optional features can be added to fit all installation requirements. Low installation costs The complete assembly of the units and function testing at the factory reduces the cost of installation on site. rigid steel base distributes the weight of the unit to the support points and allows simple installation by an easy access to the lifting points. The units are designed with a single point three-phase mains connection. ll units are supplied complete with refrigerants HCFC 22, HFC 0C or HFC 13a. Low maintenance costs The microprocessor safety and control system allows the trouble shooting of any type of functional anomaly, enabling simpler, safer and timely intervention by the unit maintenance personnel. The oil heater in the sump on each compressor and a complete set of controls and safety devices protect the unit from abnormal operating conditions. Code requirements ll units are designed and manufactured in accordance with applicable selections of the following which are equivalent to merican ir-conditioning industry applicable codes: Rating of chillers: UNI 01 Construction of pressure vessel: TÜV Standards (optional) Electrical codes: IEC 20-1 CEI - Elect. & Safety Codes Safety Codes: CEI-EN Codes Manufacturing Quality Stds: ISO 001 Factory testing Each unit is pressure tested, evacuated and charged with the refrigerant requested. It is then tested at the factory s test bench under the design conditions specified by the customer. Upon request, a second series of tests can be carried out witnessed by the customer (see option 2). Before shipment, each unit is re-checked for pressure and refrigerant charge control. General characteristics Cabinet and structure The cabinet is made of galvanized steel sheet and painted to provide a high resistance to corrosion. The unit base frame has holes to lift the unit with ropes for an easy installation. The weight is uniformly distributed along the profiles of the base and this facilitates the arrangement of the unit s bases and the support structures. The electrical and control equipment is located inside cubicles which can be accessed by key locked doors complete with door interlocking on the power cabinet. Semi-hermetic compressors Compressors are reciprocating type, or cylinders with suction and discharge valves of the disc type. The forced lubrication is obtained through a reversible gear type pump. The oil heater is automatically switched on when the compressor stops to prevent oil dilution from liquid refrigerant and in order to keep the right fluidity. The electrical motors are protected against thermal over load through thermistors embedded in each of the three phases of the statoric windings. The units, are equipped with McQuay 00 and 00 S compressors. Evaporator The evaporator is a direct expansion shell-and-tube type with water flowing in the baffled shell side and refrigerant flowing through the tubes. The evaporator are designed in more separate refrigerant circuits, one for each compressor. The evaporator is manufactured with a carbon steel shell and seamless high efficiency copper tubes. Roll expansion anchors the refrigerant tubes in the heavy carbon steel tube sheet. Water baffles are polypropylene to resist corrosion. Refrigerant head is in carbon steel and is removable to permit access to the tubes. The evaporator is wrapped with closed-cell heat insulation. Condenser coils The new units are constructed with internally enhanced seamless copper tubes arranged in a staggered row pattern and mechanically expanded into McQuay lanced and rippled aluminium condenser fins with full fin collars. n integral subcooling circuit provided sufficient sub cooling to effectively eliminate liquid flashing and increases in cooling up to % without increasing in absorbed power. Condenser coil fans The condenser fans are of the helical type with wing-profile blades to achieve a better performance. The direct coupling with the electrical motor eliminates any problems as regards the application of transmission devices and reduces the vibrations caused by the functioning. The motors are supplied as standard totally enclosed (Insulation class F) and are of the three-phase type; they are protected against overloading and short circuits by circuit breakers located inside the electrical control panel. The fans operate in formed bell shaped orifices. Electrical control panel The components of both the power and the control are split into two sections of one main panel, accessed by individual key locked doors to prevent unauthorised entry. The panel is manufactured to insure protection in all weather conditions and the doors are fitted with door-stays to prevent accidental closure. The power panel is fitted with a door interlocked mains isolator to prevent access while it is live. Power section includes: This section of the panel includes contactors, all the fuses for the compressors and the condenser fans, control circuit transformer. dditional space is provided for the installation of the various optional accessories provided to enhance the capabilities of the units. Control section includes: Microprocessor is installed as 302 B - /0 - page 2/2

On request, a second test can be carried out, at customer s presence, in accordance with the procedures indicated on the test form. Selection Procedures The procedure for selecting the cooling duty and the power absorbed by the compressors of the units is indicated below. 1. The tables Standard unit performance allow to determine the cooling, power absorbed by the compressor motors with cooled water temperatures between + C and + C, ambient air temperatures between + 2 C and +2 C. 2. lthough the data can be interpolated, extrapolation is not permitted. For conditions other than those shown in the tables, contact McQuay Product Group. 3. The performance of the units refers to C of t of chilled water. The increase or reduction of the flow rate of chilled water produces a reduction and an increase in the cooling performance which is negligible. To ensure the correct functioning of the exchanger, it is advisable to maintain the water s t within 3 C C.. The performance figures are based on Fouling factor of 0.0 m2 C/. In the event of different values, the correction coefficients indicated in Table 2 should be used.. The performance is influenced by air density. Table 3 gives the correction factors for the various altitudes above sea level.. The power absorbed values given in the standard performance tables refer to the compressors only. The 302 B - /0 - page 3/2

4 current absorbed by the fans is given in the electrical characteristics table.. To obtain the flow resistance through the evaporator, use the diagrams on page. Example of selection of an unit Data: Cooling required: 0 mbient air temperature: + C Temperature of cooled water: from 12 to C Refrigerant: HCFC22 Fouling factor: m2 C/ ltitude above sea level: 00 m Glycol content: none 1. The cooling correction coefficient for fouling m2 C/ (Table 2) is The cooling correction coefficient for installation at 00 m above sea level (Table 3) is The corrected cooling is 0 /0./0. = 1.. The cooling unit to satisfy this is ST 022. This unit will have the following operating data: Cooling : x 0. x 0. = 2, Power absorbed by compressors: 23,1 x 0. x 1.01 = 23,3. Chilled water flow rate: 2, /.1/(12-) = 31,2 l/s. Pressure drop indicated by the diagram on page with a cooled water flow of 31,2 l/s on the straight line corresponding to the unit we find a pressure drop of 32 kpa. Water content in cooling circuits The cooled water distribution circuits should have a minimum water content to avoid excessive intermittent operation of the compressors. In fact, each time the compressor starts up, an excessive quantity of oil goes from the compressor s sump and simultaneously there is a rise in the temperature of the compressor motor s stator due to the inrush current during the start-up. To prevent damage to the compressors, McQuay has envisaged the application of a device to limit frequent stops and restarts. During the span of one hour there will be no more than starts of the compressor. The plant side should therefore ensure that the overall water content allows a more constant functioning of the unit and consequently greater environmental comfort. The minimum installation water content envisaged should be calculated with a certain approximation using this formula: (1) Q = P x p 2 where: Q = minimum content of the plant expressed in litres. P = cooling of the plant expressed in W p = minimum unloading percentage plant with a cooling in which the cooling unit LR ST 022 equipped with two compressors is applied, should have a minimum content of water calculated on the basis of the minimum cooling, which for this type of equipment is 2% of the nominal. Q = 000 x 0.2 = 0 l 2 For a more accurate determination of the quantity of water, it is advisable to contact the designer of the plant.when the sum of the water content of the evaporator, the pipes of the hydraulic circuit and the terminals (coils, exchangers, etc.) is lower than the value obtained, it would be better to opt for a LR McQuay cooling unit equipped with inertial tank (optional).

5 Installation notes Handling ll moving and handling may damage the unit if some conditions are not scrupulously observed. The units should be lifted with a crane using long ropes anchored to the holes on the frame of the unit s base and by using the upper spacer bars (see accessory 0) to prevent the ropes from damaging the condenser coils. Location The LR units are produced for outside installation on roofs, floors or below ground level on condition that the area is free from obstacles for the passage of the condensation air. The unit should be positioned on solid foundations and perfectly level; in the case of installation on roofs or floors, it may be advisable to arrange the use of suitable weight distribution beams. When the units are installed on the ground, a concrete base at least 20 mm wider and longer than the unit s footprint should be laid. Furthermore, this base should be sufficiently robust to withstand the unit weight mentioned in the technical data table. When the units are positioned in areas which are easily accessible by persons or animals, it is advisable to fit guards to protect the condenser coil guards (see accessory 32) and, when necessary, also guards to protect the compressor (see accessory 33). Space requirements The units are air-cooled, hence it is important to observe the minimum distances which guarantee the best ventilation of the condenser coils. Limitations of space reducing the air flow could cause significant reductions in cooling, an increase in electricity consumption and, in some cases, the unit may stop functioning as a result of the high condensation pressure. The fans do not allow the use of ducts which have high flow resistance, hence is should be ensured that the output air cannot recycle itself inside the condenser coils. The units should be positioned such that there is sufficient distance between the coils and any obstacles to improve ventilation and also to facilitate inspection. When two or more units are positioned side by side it is recommended that the condenser coils are at least 3000 mm distance from one another. Smaller distances could cause the recirculation of hot air. If the units are positioned in places surrounded by walls or obstacles of the same height as the units, the units should be at least 3000 mm from said obstacles. For other installation solutions, consult McQuay technicians. coustic protection The low noise levels of the LR units means that they meet most of the most restrictive regulations, thanks to the availability of two versions with different sound levels: the standard version (ST), the version with sound proofing cabinet on compressors (CN). When the noise level must meet special requirements it will be necessary to pay the maximum attention to ensure the perfect insulation of the unit from the support base by applying appropriate vibrationdampening devices (see accessories and ), applying vibration-dampening mounts on the water pipes and on the electrical connections.
