Siemens has conducted two seminars in partnership with the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) on the topic of mechanical Pressure Independent Control Valves (PICVs).
Discussing the market experiences and energy-saving considerations of PICVs, the first two in the series of seminars have been held in Saudi Arabia and the next will be in Cairo, Egypt on 15 April 2019.
PICVs have the potential to make a significant contribution to energy efficiency in buildings, and offer cost benefits by preventing oversupply of chilled water to heat-exchangers/terminal units and ensuring optimum usage of cooling generation.
“We are seeing greater support for hydronic balancing within the engineering community, but much still needs to be understood about the technology, which requires the integration of digital applications with mechanical hardware,” said Heiri Walker, head of CPS at Siemens Middle East. “With these seminars we’re aiming to address concrete guidelines for assessing expected performance of PICVs and their benefits to the system.”
“ASHRAE RAL strives to support knowledge dissemination in the Middle East region with highly diversified expertise and talented members,” said Dr. Ahmed Alaa Eldin Mohamed, director & regional Chair, Region at Large, ASHRAE. “This region is the largest globally for ASHRAE, and we are pleased to be partnering with organizations like Siemens to establish valuable seminars for those eager to learn about key topics in our industry.”
Pressure-independent valves combine a control valve for temperature, a differential pressure controller for shielding against pressure fluctuations in the hydraulic network, and a pre-setting scale for setting the maximum required volumetric flow, to control accuracy of systems under all operating conditions. With increased precision over control of the volumetric flow, the valves contribute to better environmental comfort in buildings.
