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

    摘要: Refrigerant system schematics are provided with enhanced humidity and temperature control of the air supplied to an environment to be conditioned. In particular, an economizer cycle is incorporated to be utilized in a combination with a reheat coil. Proposed system configurations enhance system performance characteristics, offer more steps of unloading, especially in the reheat mode of operation, and operate at improved reliability. Additionally, due to the enhanced performance of the economizer cycle, the reheat coil size can be reduced.

    摘要: A heat pump is provided with a method and control for eliminating flooded starts. In particular, the heat pump at start-up is operated for a short period of time in the opposite mode to that in which it had been operated before the previous shutdown. In this way, the compressor ingestion of liquid refrigerant is limited or completely eliminated. After a short period of time, the heat pump is moved back to the intended mode of operation. Additional features can be added to the control scheme to limit this type of operation at start-up only to certain ambient conditions or only to a prolonged period between shutdown and start-up.

    摘要: A refrigerant system is provided with a reheat function selectively utilizing the heat rejected by the variable speed drive controller and electronics that are often employed in known refrigerant cycles. By placing at least one of these variable speed drives in the path of air being delivered to an environment to be conditioned, the air is reheated to a desired temperature, after it has been overcooled in the evaporator to provide a desired humidity level. In this manner, the variable speed drive is cooled, and the reheat function is provided, without the requirement of any additional flow structure.

    摘要: Various refrigerant system schematics incorporate the ability to bypass refrigerant around a condenser, to selectively provide refrigerant of a desired thermodynamic state to downstream system components, including a reheat coil located downstream of the condenser. In addition, the reheat coil may be utilized in combination, or independently from an economizer cycle, that is also incorporated into the system design. The economizer branch can be configured in a sequential or parallel arrangement relative to the reheat coil. Consequently, a wide spectrum of sensible and latent load demands can be satisfied. Furthermore, various schematics provide distinct benefits and flexibility in unloading and temperature and humidity control, also resulting in system performance and reliability enhancement.
