Abstract (en)
[origin: WO2008130412A1] A refrigerant system, which utilizes CO<SUB>2</SUB> as a refrigerant, includes a main closed-loop refrigerant circuit and a booster closed-loop refrigerant circuit. A heat accepting heat exchanger, which provides extra cooling for the refrigerant circulating through the main circuit, and thus improves refrigerant system performance, also serves as a shared component coupling the two circuits through heat transfer interaction. Various schematics and configurations for the booster circuit, which may be combined with other performance enhancement features, are disclosed. Additional benefits for economizer function, "liquid-to-suction" heat exchanger, intercooling and liquid injection are also presented. The booster circuit may also contain CO<SUB>2</SUB> refrigerant.
