First claim
Opening claim text (preview).
I claim: 1 . A variable capacity condensing unit for use with a refrigeration system, comprising: a gas cooler or a condenser; one or more fans; and a plurality of fractional compressors. 2 . The variable capacity condensing unit of claim 1 , wherein the plurality of fractional compressors comprises a parallel configuration. 3 . The variable capacity condensing unit of claim 1 , wherein the plurality of fractional compressors comprises a series configuration. 4 . The variable capacity condensing unit of claim 1 , wherein the plurality of fractional compressors comprises a combined parallel configuration and series configuration. 5 . The variable capacity condensing unit of claim 1 , wherein the plurality of fractional compressors comprises about one (1) horsepower or less. 6 . The variable capacity condensing unit of claim 1 , wherein the plurality of fractional compressors comprises a variable frequency. 7 . The variable capacity condensing unit of claim 1 , wherein the plurality of fractional compressors comprises a set of operational compressors and a set of backup compressors. 8 . The variable capacity condensing unit of claim 1 , further comprising a compressor rack and wherein the plurality of fractional compressors is positioned in the compressor rack. 9 . The variable capacity condensing unit of claim 1 , wherein the plurality of fractional compressors comprises an on/off compressor valve. 10 . The variable capacity condensing unit of claim 1 , wherein the gas cooler comprises a condenser or a gas cooler coil. 11 . The variable capacity condensing unit of claim 1 , further comprising a carbon dioxide refrigerant or a hydro-fluorocarbon refrigerant. 12 . The variable capacity condensing unit of claim 1 , wherein the variable capacity condensing unit is in communication with an expansion valve. 13 . The variable capacity condensing unit of claim 1 , wherein the variable capacity condensing unit is in communication with one or more evaporators. 14 . The variable capacity condensing unit of claim 13 , wherein the one or more evaporators comprise an evaporator coil and an evaporator fan. 15 . A method of operating a condensing unit in a refrigeration system, comprising: positioning a plurality of fractional compressors in a parallel configuration; flowing a refrigerant through a number of the plurality of fractional compressors; and varying the number of the plurality of fractional compressors with the flow of refrigerant based upon one or more operational parameters. 16 . A refrigeration system, comprising: an evaporator; and a variable capacity condensing unit; wherein the variable capacity condensing unit comprises a plurality of fractional compressors. 17 . The refrigeration system of claim 16 , wherein the plurality of fractional compressors comprises a parallel configuration. 18 . The refrigeration system of claim 16 , wherein the plurality of fractional compressors comprises a series configuration. 19 . The refrigeration system of claim 16 , wherein the plurality of fractional compressors comprises a combined parallel configuration and series configuration. 20 . The refrigeration of claim 16 , wherein the plurality of fractional compressors comprises about one (1) horsepower or less.
