With all passes used for cooling (two pipe), the coil cooling power output has been increased by up to 50 percent compared to the company’s previous highest capacity chilled beam. The SEMCO IQHC beam now delivers a cooling capacity (at typical design conditions) while using less pump energy. When configured as a four pipe beam (heating and cooling), the IQHC is available with added heating passes (if needed) to provide a substantial increase in heating output when compared to the company’s previous highest heating capacity beam. These capabilities increase system energy efficiency while reducing the length of the beams that may be needed, thereby reducing the
first cost of the project.
With 12 field adjustable slots, almost any combination of beam pressure and air flow can be easily commissioned in the field without the need for additional tools or changing/plugging nozzles. As important, limited slot/nozzle selections makes it difficult to supply the air flow required while simultaneously maintaining the desired system pressure to provide the necessary cooling and/or heating capacity. This means that most, if not all SEMO IQHC beams can be selected at the same, low pressure which greatly simplifies the commissioning process and saves the installing contractor substantial labor hours. Each beam can be installed in seconds once the IQHC installation brackets are secured. Once installed, the beam can be easily aligned to match the fit the ceiling tiles.
A commissioning tube is conveniently located (preinstalled at the factory) within each IQHC beam to quickly and accurately measure the chilled beam operating pressure during the startup process. The beam slot setting is easily adjusted in seconds, without the need of tools, using the adjustment arm and index markings of the integral air-flow adjustment station to achieve the primary air flow desired. Knowing the slot setting and beam pressure, the primary airflow can be easily determined from a convenient table.
The IQHC has been developed to be visually pleasing to the room occupants using quality materials and finishes. The unique “swing down” cover plate makes inspecting or vacuuming the integrated coil a breeze. It also allows modifications to the slot settings to be made efficiently since the air-flow adjustment station is easily visible and accessible when the cover plate is open.
The IQHC beam has a standard low profile design which minimizes the ceiling height required for installation. However, some renovation projects which are especially suitable for the use of chilled beams have very limited ceiling space and require the lowest possible beam height. To accommodate such applications, the IQHC beam is offered in an optional low-profile configuration thereby minimizing the installation height requirement while providing the same high cooling and heating capacity offered by our standard IQHC product.
