Hybrid tandem compressor system with multiple evaporators and economizer circuit

摘要: A tandem compressor refrigerant cycle with an economizer circuit is introduced to provide additional capacity and improve system efficiency. In this system, compressors deliver compressed a common discharge manifold, then condenser. From the condenser, passes plurality of evaporators, each evaporators being associated separate environment be conditioned. Each one compressors. By utilizing yet ability independently condition number environments achieved without requirement same complete circuits for environments. some embodiments, several can provided by banks having its own Some in bank have intermediate injection ports accept vapor from circuit. particular, provides relatively high load requirements.
