[continue reading] Case Studies MSC was retained at a four-story Northern New Jersey hospital that had been renovated in three phases over the course of several years. Upon completion of the final phase, an air volume shortage was detected when system balance reports indicated the system was providing just 60% of the 50,000 CFM specified in the design. MSC's assignment was to confirm or disprove the low volume condition, determine the cause, and provide recommendations for corrective measures. Hospital OR: Slow Space Pull-Down and Poor Temperature Control A hospital reported slow temperature pull-down between surgeries involving surgical teams with different space requirements as well as poor temperature control. MSC was called in to determine the cause of these issues and provide recommendations for improving performance. While the equipment proved to be of adequate size and configuration, a number of system deficiencies were identified, the main problem being excessive air volume that did not allow proper heat exchange to occur. View Diagnostic Report Large NJ Hospital: Underperforming Heating Coil MSC was called in to examine and diagnose an issue with a steam heating coil located in a lower level mechanical room in a large NJ hospital. The coil was logging condensate and not draining properly under normal operating conditions, causing nearly half of the coil surface area to remain unheated. Utilizing a thermal imaging camera and various testing procedures, we determined that space and elevation issues rendered the existing coil and trap unable to overcome external pressure drops required to effectively remove the steam condensate. View Diagnostic Report Split Unit Evaluation in New 7-Story Corporate Headquarters The piping configuration of a 100-ton rooftop-mounted condensing unit and an air handler located six floors below came into question when both scroll compressors failed due to high head pressure and high FLA readings, causing the unit to trip on the overloads. MSC was tasked with inspecting the piping in the new 7-story corporate headquarters, comparing it with the design, and determining the appropriate steps to correct existing problems.
