GOING OIL-FREE with chiller compressors

摘要

One of the key operational challenges for universities, schools, hospitals and other institutional buildings is getting the best possible performance from the HVAC system's chiller over long hours while keeping maintenance costs to a minimum. Oil-free compressors can help meet this challenge.Traditional compressors, such as screw-type, require oil for lubrication of their bearings, to support the movement of the rotor and to form a seal to prevent refrigerants from travelling in the wrong direction.
