Program: Understanding Dehumidification Performance at Part Load in Commercial Applications (1 PDH)


The part load performance of DX and chilled water cooling coils at part load conditions is not well understood.  For packaged air conditioners the DX cooling coil turns on and off in response to room thermostat.  During the off cycle, some moisture evaporates from the coil and goes back into the airstream – especially if the supply fan runs continuously.  For chilled water coils similar reductions in dehumidification capacity occur as chilled water flow is reduced.   In both these cases moisture removal effectiveness is reduces and space humidity levels rise.   The presentation presents results from field and laboratory testing of cooling coils to quantify these affects.  Practical control and sizing guidance is provided for practicing engineers.
