ZONING HYDRONIC SYSTEMSDownload
Welcome to the 5th edition of idronics™, Caleffi's semi-annual design journal for hydronic professionals.
Zoned heating systems have been used for centuries. Even before hydronic heating was available, buildings were often divided into two or more areas in which comfort could be independently controlled - often through the use of individual heat sources such as fireplaces or stoves.
Today, zoning is a preeminent benefit of hydronic heating and cooling. When properly applied, it provides unsurpassed comfort control, flexibility and energy conservation.
To take full advantage of these benefits, designers must understand several principles that let zoned systems quickly adapt to constantly changing interior and exterior conditions. As has been the custom with idronics, these principles are discussed at a level appropriate for hydronic design professionals. They are then demonstrated in a wide variety of application drawings based on the latest hardware and design techniques. The goal is to facilitate zoned hydronic systems that are flexible, reliable, simple to build and highly energy efficient.
We trust you will find this issue a useful educational tool and a handy reference for your future system designs.
