ABSTRACT:
A refrigerant cycle is provided with a compressor system, capable of simultaneously delivering refrigerant to multiple condensers operating at different temperature levels. A single evaporator communicates with these condensers. One of the condensers receives fully compressed refrigerant while the others receives refrigerant at an intermediate pressure. A control can optionally direct refrigerant to only one of these condensers to achieve desired heat rejection and other operational characteristics. Various system configurations with multiple compressors and condensers are also disclosed.
