Chapter 9 - Hydronic System Architecture

Abstract

This chapter introduces the basic layout options for heating and cooling piping arrangements that distribute water or steam with the use of hydronic circuits. Hydronic systems are involved with the flow of steam or water to transfer heat or cooling from one place to another. The chapter discusses the various types of water systems such as steam systems, hot water heating systems, chilled water systems, and open water systems. In each type of system, the flow of water or steam is distributed from either a central boiler or a chiller (the refrigeration equipment used to produce chilled water) to the hydronic circuits. The hydronic circuits circulate the water or steam through the building, where it loses or gains heat before returning to be re-heated or re-cooled. The water or steam is treated with chemicals to inhibit corrosion and bacterial growth in the system.
