Evaporative condensers provide heat rejection for many types of systems, and the specific application will largely determine which Evaporative Condenser is best suited for a project. The information contained within this section is geared towards the use of evaporative condensers in the HVAC and light industrial markets only. Evaporative condensers are used in these markets to provide lower condensing temperatures and compressor horsepower savings of up to 15 percent when compared with traditional systems.

Principle of Operation

The vapor to be condensed is circulated through a condensing coil, which is continually wetted on the outside by a recirculating water system. Air is pulled over the coil, causing a small portion of the recirculating water to evaporate. The evaporation removes heat from the vapor in the coil, causing it to condense.

Configuration

EAC manufactures two types of evaporative condensers: combined flow and counterflow.

Combined Flow

Combined flow is the use of both a condensing coil and fill surface for heat transfer in an evaporative condenser. The addition of fill surface to the traditional evaporative condenser design reduces evaporation in the coil section, reducing the potential for scaling and fouling. EAC’s combined flow evaporative condensers utilize parallel flow of air and spray water over the coil, and crossflow air/water flow through the fill surface.

In parallel flow, air and water flow over the coil in the same direction. In the fill section of EAC’s combined flow evaporative condensers, air and water interact in a crossflow configuration: water flows vertically down the fill as air flows horizontally across it.

Combined Flow: Parallel Flow of Air and Water Over the coil

Combined Flow: Crossflow Configuration Over the Fill

 

Counterflow

In a counterflow evaporative condenser design, the flow of the air is in the opposite direction of the spray water. In EAC’s counterflow evaporative condensers, air travels vertically up through the unit while the spray water travels vertically down over the coil.

Counterflow Configuration

The flow of air through most factory assembled evaporative condensers is provided by one or more mechanically driven fans. The fan(s) may be axial or centrifugal, each type having its own distinct advantages.
