Abstract

A refrigeration system for use in cooling electronic equipment includes a closed vapor compression circuit having operably disposed therein a compressor, a condenser, a first expansion device, a second expansion device, and a two-part evaporator. A first part of the evaporator receives working fluid from the first expansion device at a first pressure, and a second part of the evaporator receives working fluid from the second expansion device at a second pressure that is different than the first pressure.
