Prevent Condensation From Becoming A Design Flaw

Water condensation is easily the most common concern when discussing chilled beams and cooling panels. This concern comes from the personal experience many have had seeing water droplets form on the surface of piping such as a water coil.

When condensate forms it is too late to prevent the surface from becoming wet. The question, however, is how to prevent condensate from becoming a design flaw in the building.

The HVAC designer needs to verify that the ventilation system is capable of handling the latent load. Humidity loads that need to be addressed include:

  • Ventilation Load: Generally the largest moisture load.
  • Infiltration Load: Moisture that crosses the building shell.
  • Occupant Load: As people breathe and perspire, moisture is released into the space.
  • Other Loads: Fountains, doors and windows left open, wet clothing, etc.

To provide control of the air dew point and supply water temperature, several different control strategies are often used.

  • Monitor the local dew point temperature.
  • Monitor condensate on the chilled water supply (CHWS) piping.
  • Reset the CHWS temperature based on outdoor conditions.

Often, a combination of these control strategies is used. Other considerations are the type of fresh air systems (DOAS), system response time, building start up, night setback and recovery after high humidity levels in the interior space.

FINDING THE BALANCE

balancestream-climate-systems

ClimateCraft is a custom air handler manufacturer that has created BalanceStream technology. It has only one moving part, improves fan array system efficiency, and reduces maintenance and energy costs.

It solves many part load system operational problems and reduces system instability by eliminating fan surge.

Improved Operational Performance

  • Eliminates the need for backdraft dampers and provides automatic shut-off in case of a fan failure.
  • Improves overall system efficiency as it does not obstruct the fan intake; therefore, there are no associated intake losses or impact on operating BHP.
  • Provides operational consistency by allowing fans to maintain high efficiency over the entire operating range.
  • Solves part load system operational problems by:
  1. Allowing fans to provide controlled static pressure at flows down to 10% of design without cycling fans.
  2. Allows the fans to run stably and efficiently at part load flow at elevated static pressure.
  3. Completely eliminating the need to cycle fans; therefore, maintaining a consistent flow profile that is potentially lost when fans are cycled off.
