System interaction and integration is moving forward at an aggressive pace. John Vastyan, of Common Ground in Manheim, Pennsylvania, wrote on HPAC Engineering that hydronic system performance used to have many individual facets and important details, such as chiller or boiler type, system design and key components.
Now, system integration innovation is moving quicker than ever. Vastyan spoke to Richard Medairos, PE, senior systems engineer and director of commercial training for Taco Inc., who said system integration is something the industry has been working toward for decades.
Medairos has been involved in hydronics and commercial-buildings design for more than 30 years, most of them as an independent consulting engineer. What he sees on the horizon is unprecedented energy efficiency, sustainability, ease of operation, and interior comfort.
Medairos credits the merging of system equipment, components, and terminal units; piped networks; high-efficiency, reactive pumps; and building automation systems (BAS) with predictive controls.
One of the latest advancements, Medairos said, has been the expanding reach of sensorless and electronically-commutated-motor (ECM) pumps.
“These pumps—without the need for external sensors—are making it possible to provide the pumping power for large heating and cooling systems with amazing efficiency,” Medairos said.
