摘要： A humidity control method is provided for a multi-stage cooling system having two or more refrigerant circuits. A hot gas re-heat circuit having a hot gas re-heat coil, an evaporator and a compressor, such as the evaporator and compressor utilized in one of the refrigerant circuits, is provided. The hot gas re-heat coil is placed in fluid communication with the output airflow from the evaporator of the re-heat circuit. Humidity control is performed during cooling operations and ventilation operations. During a first stage cooling operation using only one refrigerant circuit and having a low cooling demand, the request for humidity control activates the hot gas re-heat circuit for dehumidification and activates a second refrigerant circuit to provide cooling capacity. During a second stage cooling operation using multiple refrigerant circuits and having a high cooling demand, the request for humidity control is suspended until completion of the second stage cooling demand.

摘要： A humidity control method is provided for a multi-stage cooling system having two or more refrigerant circuits that balances humidity control and cooling demand. Each refrigerant circuit includes a compressor, a condenser and an evaporator. A hot gas reheat circuit having a hot gas reheat coil is connected to one of the refrigerant circuits and is placed in fluid communication with the output airflow from the evaporator of that refrigerant circuit to provide additional dehumidification to the air when humidity control is requested. The hot gas reheat circuit bypasses the condenser of the refrigerant circuit during humidity control. Humidity control is only performed during cooling operations and ventilation operations. During a first stage cooling operation using only one refrigerant circuit and having a low cooling demand, the request for humidity control activates the hot gas reheat circuit for dehumidification and activates a second refrigerant circuit to provide cooling capacity. During a second stage cooling operation using two or more refrigerant circuit and having a high cooling demand, the request for humidity control is suspended and is initiated only upon the completion of the second stage cooling demand.
摘要翻译：提供一种用于具有平衡湿度控制和冷却需求的两个或更多个制冷剂回路的多级冷却系统的湿度控制方法。每个制冷剂回路包括压缩机，冷凝器和蒸发器。具有热气体再热线圈的热气体再热回路连接到一个制冷剂回路，并且与来自该制冷剂回路的蒸发器的输出气流成流体连通，以便在要求湿度控制时向空气提供额外的除湿。湿气再热回路在湿度控制期间旁路制冷剂回路的冷凝器。湿度控制仅在冷却操作和通风操作期间进行。在仅使用一个制冷剂回路并且具有低冷却需求的第一阶段制冷操作期间，对湿度控制的请求激活用于除湿的热气再热回路，并且启动第二制冷剂回路以提供冷却能力。在使用两个或更多个制冷剂回路并具有高冷却需求的第二阶段制冷操作期间，停止对湿度控制的请求，并且仅在第二阶段冷却需求完成时启动。
