SmartCool™ i-drive is a highly versatile, inverter compressor precision air conditioning unit within the Airedale product range. Optimised for both hot and cold aisle containment, the system is ideally suited to data centre applications and low, medium, high density computer room cooling applications.The incorporation of inverter compressors enables exact control, superior efficiency and performance. The SmartCool™ i-drive delivers precise supply air temperatures up to 26°C within a wide ambient envelope of -20°C to 50°C. It is a system prepared for every eventuality, responding to unexpected load variations to deliver market leading cooling density. SmartCool™ i-drive units provide up to 83kW of downflow cooling within 4 case sizes from 900mm x 890mm x 1980mm to 1800mm x 890mm x 1980mm. All units are single circuit DX air-cooled with various configurations of inverter driven and fixed speed compressors. As well as high part load efficiencies and constant pressure control.

The SmartCool™ i-drive system also benefits longer pipe runs for increased flexibility, allowing outdoor condensers to be situated up to 100 metres from any internal unit.The SmartCool™ i-drive’s slab coil configuration and use of optimised EC fans delivers low fan power input and reduced airside pressure drop. A performance led selection of features and options come together within the i-drive range to make your facility more productive and efficient.

In layman term, the compressor compresses or squeezes the vapor into a smaller volume at high temperature. The external-drive compressor has a crankshaft that is driven by a pulley and belt system.An electric motor can also be used to drive it directly. The hermetic compressor has a motor which is sealed inside a housing with the compressor, hence a crankshaft seal is not required. The motor rotor is located either at the top or bottom of the unit. There are basically 5 types of air conditioner compressor that are commonly used in the HVAC industry: The reciprocating compressor uses piston to compressor the refrigerant driven by a crankshaft in a straight line back and forth motion.

This rotary motion is achieved by the use of an electric motor and the construction is quite similar to that of an automobile engine.The piston moves up and down inside a cylinder. Vapor from the suction line is moved through the intake valve as the piston move downward. As the piston moves upward, it compresses the vapor refrigerant which is then pushed through the exhaust valve into the condenser.The compressor may has more than one cylinder which is also known as multicylinder compressor. The common ones are the two-cylinder, four-cylinder and eight-cylinder compressorsA scroll compressor has one fixed scroll which remains stationary and another moving or orbiting scroll that rotates through the use of swing link. When this happens, the pockets of refrigerant between the two scroll are slowly pushed to the center of the two scrolls causing the reduction of the volume of the gas. It is then discharged though the center port to the condenser.The advantage of scroll compressor is that it has fewer moving parts and less torque variation compared to the reciprocating compressor.

This advantage is translated to a smooth and quiet operation.The scroll compressor is also known as scroll pump or scroll vacuum pump. The screw compressor uses a pair of helical rotors where it traps and compresses the gas as the rotors revolve in the cylinder. In HVAC, they are usually used in systems with 20 ton capacity and above. The male rotor and the female rotor are built inside the cylinder. The low pressure refrigerant enters one end of the compressor and the resultant high pressure refrigerant is discharged into the opposite end to the condenser.The rotary compressor can be divided into two types. One has blades or vanes that rotate with the shaft. The other type has the blade which remains stationary and is part of the compressor housing assembly. In both types, the vapor from the suction line is drawn into the cylinder through the suction port.As the blade rotates, trapped vapor in the space ahead of the blade is compressed into high pressure gas after which it is discharged to the condenser through the exhaust port.
