|---|---|---|---|---|
| Term Cell Control Type |
Term Definition
Cooling tower cell control type. A cooling tower cell is the smallest tower subdivision bounded by either exterior walls or partition walls, which can function as an independent unit with regard to air and water flow. Most larger cooling tower systems use a multiple-cell configuration. This configuration allows for the correct staging of equipment as the facility loads vary and incorporate redundancies such that critical operations are never in jeopardy of being nonoperational. |

| Term Cell Count |
Term Definition
The number of cells in the cooling tower. Each cell has its own fan, water flow allowing for responding to lower load conditions |

| Term Compressor Staging |
Term Definition
The compressor staging for the unit. Select "Single Stage" for units with single stage (on/off) control. Select "Multiple, Discrete Stages" for units with multiple compressors, discrete unloading stages, or compressors with stepped speed motors that are controlled to operate at discrete stages. Select "Variable" for compressors that operate at variable speeds or with modulating unloading. |

| Term Condenser Fan Speed Operation |
Term Definition
The condenser fan control option used by the unit. If the unit has several constant-speed condenser fans that stage on in conjunction with multiple compressors, this should be set to ÒStepped Speed.Ó |
