MAIN CHARACTERISTICS AIR CONDITIONING SYSTEM The high-performance screw chiller is designed depending on 30 years research & development experience of LS Air-Conditioning System. High-performance compressor manufactured by specialized manufacturer is adopted to ensure that the chiller is economical and durable with low vibration and low noise. The primary and secondary selection function the double-head chiller compressor evenly used and hence the service life of entire machine is prolonged. Highly integrated motherboard is adopted and hence the function is strong and reliable. Model description Advanced control algorithm is adopted to control chiller in advance and hence avoid frequent stoppage protection of chiller. We have set complete safety protection function in order to make chiller safely and reliably run. The linkage control and remote monitoring function of peripheral equipments ensure that the chiller can run safely and the operation and monitoring are convenient. The selection of excellent raw materials and fittings is the key to guaranteeing chiller quality. The product is divided into flooded screw chiller SFWW and dry screw chiller SWW.

INSTALLATION AND DIMENSION Chiller room requirements The design and location of central air conditioner room is a comprehensive work, which must be closely coordinated with architecture, structure, water supply and drainage, building electricity and other professional work. 1. The air conditioner room should be located as near as possible to the cooling load center. For High-rise buildings with basement available for use, it should be located in the basement; for super high-rise building, it may be located at middle floor (technical equipment floor) in accordance with system division; for air conditioning modification or addition works, it may also be reconstructed outside air conditioning building or located at the roof or other place of air conditioning building, while it must be guaranteed that the building structures have enough bearing capability. 2. The equipments in the air conditioner room should be arranged closely to save covered building area. The equipment arrangement and pipe connection should accord with technological flow requirement and be easy to install, maintain and repair. 3. When the tube shell and the heat exchanger of chiller are arranged, the possibility to clean and replace tube nest should be considered. Generally, a space with length equal to chiller length will be left on one end of chiller. If there is no enough space, one end of chiller in the length direction may be directly faced to window with proper height for lighting or to gate with proper height. 4. The air-conditioner room should be made of Grade II refractory materials or incombustible materials with good sound insulation property. The room should have two exits as far as possible from each other, of which at least one should directly face to outside. Also, the direction of opening should be towards the outdoor. 5. please refer to Air conditioner Room Guaranteed Space for room height. 7. When the central air conditioner room is located in the basement, it Space between equipments in machinery room should be equipped with mechanical ventilating equipment and the least air displacement of such equipment should not less than 36.5G2/3(m3/H), where: G is the total cooling capacity of chiller. In order to reduce air displacement under non-emergency conditions, it is recommended to use multi-speed blower. The inlet and conduit of exhausting blower should be near to chiller with proper protection. 8. The central air conditioner room inside should be equipped with water discharging facilities and toilets and if available, with telephone. Also, emergency lighting should be taken into consideration. 9. The inflammable and explosive materials are not allowed to be stored in the air conditioner room except refrigerant existing in the chiller. Space between equipments in machinery room ITEMS SPACE (M) Width of main channel and operation channel >1.5 Distance between jut of chiller and switch-house >1.5 Distance between jet of chiller >1.0 Distance between chiller and wall >0.8 Width of subordination channel >0.8 Distance between side jut of the chiller >1.5 Distance between sides of absorption chill and wall >1.2 6. The host air conditioner in the central air conditioner room should be separated from pump room and control room and the repairing room and storage room should be arranged in accordance with practical conditions. If there are fuel absorption chiller or fuel central water heater in the air conditioner room, the idlest method is to obtain fuel from special oil depot through oil pipeline. If the fuel tank is placed in the room, then the floor arrangement should strictly follow relative fire codes and the house should be equipped with necessary fire-fighting equipments.

INSTALLATION AND DIMENSION Installation and size Installation requirements The installation space should be considered when the chiller are installed in order that LS service personnel are convenient to dismantle and hoist compressors and other parts. The minimum space can be determined in accordance with the table below. For multiple chiller, the space between two chiller should be not less than 120% that of single chiller. If the room space is too small, please contact LS for consultation and solution. During installation, special attention should be paid to : 1. The water pump should be installed on the side of inlet of cooled water/cooling water, if it needs to install on the outlet side, please contact LS. 2. The two sides of water pump should be installed with flexible connection to insulate pipe vibration. For water pump, the speed 2900RPM should be not chosen to the extent possible in case of resonance.
