Notas del editor

  1. The man in the middle is Will Nuckolls, head of EVAPCO’s Sound Engineering department…… and no, that is not Will’s boat propeller! The fan on the right is EVAPCO’s SUPER Low Sound Fan, which offers 9 to 15 dB(A) reduction. The SUPER Low Sound Fan is state of the art sound reducing technology that is unparalleled in the evaporative cooling industry. (click)
  2. EVAPCO’s Thermal-Pak coils feature an elliptical design which assures maximum cooling capacity. This design provides a more aerodynamic shape, which lowers air side pressure drop while allowing more water to be loaded on the coil.
  3. And here is a visual representation of how it works. (Animate!!) The warm process fluid circulates from the heat source to the coil of the closed circuit cooler. The fluid in the coil transfers its heat through the tube walls to the spray water by sensible heat transfer. Having gained heat from the coil, the spray water then falls at the rate of 12 gpm/ft2 of coil to the sump where it is circulated by the spray pump up to the spray nozzles. The warmed spray water is then distributed as a thin film over the fill surface at a rater of 6 gpm/ft2 of fill for maximum cooling efficiency. The fan system operates simultaneously, moving large volumes of air through the unit opposite the falling water. The air and water contact across the fill surface causing a small portion of the spray water to be evaporated. The evaporation process is a latent transfer of heat from the spray water to the air passing through the unit. The warm and saturated air is then discharged from the unit with final heat dissipation to the atmosphere. [Click]
  4. Introducting the HEART of the New ESWA, Evapco’s new Sensi-Coil Technology. This amazing new technology is the results of months of hard work by the Evapco Product Development and Manufacturing Teams. [Click] Sensi-Coil Technology is available exclusively on the ESWA Closed Circuit cooler. [Click]
  5. Sensi-Coil Technology includes reduced tube spacing which is perfect for sensible cooling. As shown in the diagrams, the Thermal-Pak Coil has extra spacing between the elliptical tubes to allow for airflow between the tube bundles. The Sensi-Coil has tighter tube spacing, which has been designed specifically for the flooded sensible cooling of the ESWA. Which is the reason that it is only available on this product. [Click]
  6. As I had mentioned at the beginning…the ESW provides energy savings and low sound…How Low?... [Click] 30 to 50% less horsepower than other Induced draft coolers…and up to 80% less than forced draft models. [Click] The sound levels of the ESW are as good, or slightly better than standard forced draft coolers… Let’s go through an example of the potential savings… [Click]

  10. And that is exactly what Evapco did. They designed a testing program to evaluate the performance of the Thermal-Pak coil with no air over the coil and at very high flow rates per square foot. [Click]
  11. As I mentioned a few slides back, the ESW is designed with the functionality of a discharge hood as standard. Coil heat loss in the winter is minimized by the protective panels and because freezing air does not have free passage across the coil. The ESW avoids the maintenance expense and hassle associated with lubricating hundreds of pivot pins and linkage to prevent the dampers from seizing. [Click]
  12. The ESW features the most accessible coil in the industry. When the protective panels are removed, a service mechanic has complete access to the coil and basin area. [Click]

  14. Presenter: The WDW is unique because it has a completely separate dry cooling section. There are no finned coils in the wet air stream. [click]
  15. Presenter: Evapco chose the name Sage to represent both wisdom and sagebrush – the water conserving desert plant. The Sage Control System regulates: Fan Operation, Pump Operation, Switchover Point, Water Level, the Heater Package, and Interfaces with the Building Automation System. [click]
  16. This is Stage 1, where the dry cell fan motor is on, and is cycling in VFD mode until the load requires this cell to be on full speed operation. Let’s look at this operation again. CLICK
  17. Next is Stage 2, in this mode, the dry cell goes to line power and full speed operation. The wet cell fan motor is then switched on and cycles in VFD operation . The wet cell runs dry until the fan cycles up to 100% fan speed. At this point, the load dictates that wet operation is required. At the end of this stage, the fans in the dry and wet cells are operating at 100% fan speed in dry operation. Let’t look at this mode of operation. CLICK
  18. Next we go to Stage 3, the wet/dry mode of operation, In stage 3, the dry cell is operating at 100%, and the pump is turned on in the wet cell. The wet cell fan that was running at 100% in the dry mode, now ramps down to approximately 30% fan speed operation. The fan drops in speed in the evaporative cell due to its large capacity gain with water on. The fan may even turn off on the wet cell. The fan will unload to maintain temperature and satisfy the leaving water set-point. Let’s look at this mode of operation again. CLICK
  19. This is another stage of capacity control, Stage 4. This stage occurs when the dry bulb temperature exceeds the design inlet water temperature. In this case the dry bulb RTD senses the inlet dry air temperature and if it is greater than the entering water temperature into the dry coil, the dry cell fan cuts out so that we are not adding heat to the system. This situation would occur on a very hot, dry day, like in Denver, where there is no humidity, and the wet cell will do the entire load in wet operation. Here is the last stage of operation. CLICK
  20. Presenter: Here is a sample of a graphical profile of water usage contrasting the WDW versus a Standard Induced Draft Cooler. The WDW water use numbers in m3 are in green. The standard induced draft cooler water use numbers are in blue. [click]
