This month and in the next three months, I will be sharing my experience pertaining to a design engineer who is responsible for the construction administration of the project he just completed the design for, with construction underway.
Last month, we tested readers on commissioning three of the many automatic temperature control (ATC) sequences of operation associated with the secondary hot water process heating system for an industrial building application.
There are no industry standards for rebalancing HVAC water systems, so it got me thinking about the topic and I came up with several questions pertaining to rebalancing chilled water, condenser water, and hot water heating systems.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
