An integrated mathematical model has been developed to simulate the performance of the evaporatively
cooled split AC system in a controlled space under certain operational conditions (using steady-state performance data supplied by the manufacturer and taking into account the transient effect of the compressor cycling and the manufacturer's minimum ON-OFF timing).
Performance investigation of plain and finned tube evaporatively
cooled heat exchangers.
dried biosolids which are high in soluble CL will not only affect plant performance through osmotic stress, but may also compromise product quality through Cd mobilisation.
A total economizer phase where the chiller is off, and total cooling load is met by evaporatively
cooling the chilled water return.
cooled conditioner was packaged for field testing as a 500 cfm residential dehumidifier.
Using a Rigid Media DEC upstream on the secondary airstream side and evaporatively
cool the air; 3.
The air is heated, if necessary, evaporatively
cooled to the desired dew-point temperature and then reheated to the design window.

Equipment utilizing water spray or evaporatively
cooled equipment is documented in several sources and instances and can reach energy savings of nominally 20% with paybacks as low as 1 year.
The "working air" that is normally exhausted from an indirect evaporative cooler is itself evaporatively
cooled and, if directed across the DX condenser, will be useful to improve overall COP.
In such systems, the air is first cooled sensibly without any moisture addition and then further evaporatively
cooled to achieve lower temperatures and humidity compared to that possible with simple evaporative cooling.
