Spray Chamber

 

The spray chamber is assumed to follow an adiabatic saturation process with fixed efficiency. The efficiency defines the ratio between the actual moisture take-up of the air relative to the maximum possible (i.e. from on-coil air condition to the saturated condition at the same enthalpy). This can also be thought of as saturation effectiveness, or how close the unit is able to come to providing fully saturated air.

Note that spray humidifiers either run wild or are off, i.e. it is not possible to control moisture input or off-coil conditions.

 

 Enter a description of the component. The reference is limited to 100 characters. It is for your use when selecting, organizing, and referencing any component or controllers within other component and controller dialogs and in the component browser tree. These references can be valuable in organizing and navigating the system and when the system model is later re-used on another project or passed on to another modeler. Reference names should thus be informative with respect to differentiating similar equipment, components, and controllers.

 

The spray chamber is assumed to follow an adiabatic saturation process. The efficiency defines the ratio between the actual moisture take up of the air passing through the unit relative to the maximum possible (i.e., from on air condition to the saturated condition at the same enthalpy).

 

 

The spray device itself will consume energy, as well as affecting the air condition. For example, the spray chamber may well have a circulating pump, whose power consumption should be specified. This pump is assumed to be operating when the humidifier is operating.
