Reason #4: The Quickest and Most Comprehensive Design and Selection Tool Available
The IQHC beam is supported by the “SEMCO High Capacity Chilled Beam Design and Selection Software”. This software is far more than just a beam selection tool. It is a design tool that quickly and accurately provides the following important capabilities:
□ Generates a full engineering schedule instantly □ Optimizes all beams automatically based on user defined
input parameters – allowing full beam selections for the entire project to be completed in minutes
□ Ensures that the primary airflow meets all of the following ‐ o Minimum ventilation airflow o All internal latent load requirements o Achieves the cooling and/or heating sensible loads
□ Allows for global changes to design parameters including beam water temperature, beam pressure, primary air dew point, etc. for all beams instantly
□ Allows for a quick comparison of selections made based on the best performance with those made using the shortest possible beam (lowest cost)
□ Allows manual optimization at each zone or individual beam □ Allows for cooling only or heating and cooling applications □ Estimates internal latent loads and zone area based on
application type using ASHRAE defaults to expedite selections and check for erroneous inputs
