Title: Distributed condensing units

Abstract: A system includes an evaporator unit, a first condensing unit and a second condensing unit. The first condensing unit includes a first heat exchanger coil, a first compressor, and a first oil separator, which removes oil from a refrigerant prior to the refrigerant reaching the first heat exchanger coil. The second condensing unit includes a second heat exchanger coil, a second compressor, and a second oil separator, which removes oil from a refrigerant prior to the refrigerant reaching the second heat exchanger coil. The first oil separator is isolated from the second oil separator to prevent communication of oil therebetween.
