Hvac Primary Secondary Circuits Secondary circuit in centralised hvac system. the primary and secondary circuits are connected via a pipe known as the “low loss header” it is also sometimes referred to as the “decoupler” or “common header”. the primary water flows into this to provide heated or chilled water to the secondary circuits. when the building is at. In this video we take a look at the primary and secondary circuits in a typical centralised hvac heating or cooling system within a commercial building. we l.

Primary And Secondary Circuits In Centralised Hvac Systems The Figure 2 shows a simplified schematic of a primary secondary piping system. at the bottom we see the primary piping (sometimes referred to as the “production piping”) and we see the secondary loop and cooling circuit that is connected to the primary piping at either end by two tees. Step #1: determine one pipe main flow rate. the last circuit (#4) requires 190o supply temperature for secondary circuit design conditions. given a 240o primary supply temperature, the primary circuit can be designed to a 50o Δt for the load represented by the first three circuits (#1, #2, and #3). Foolproof method for installing primary secondary . circuits. 7. more than 60 years later, primary secondary pump ing continues to provide the same advantages, but at a higher rate when used with today’s evolving equip ment. the growing popularity of condensing and other modern boilers has made the use of primary secondary piping more important. Primary secondary tertiary pumping. in a primary secondary tertiary system (figure 3), things start to get a bit more complicated, but the principles are all the same. the common pipe (whether it is between the primary loop and the secondary loop, or the secondary loop and the tertiary loop) acts as the decoupler, so flows act independently of one another and there is extra degree of thermal.

Primary secondary pumping lets you use small, inline circulators even on large commercial jobs and that's a real plus. and in a multiple boiler system, this simple method of piping gives you a way to lower boiler standby losses and save fuel. when piped properly, no water will flow through an "off" boiler when its secondary circulator stops. Primary secondary a primary secondary pumping scheme divides the chilled water system into two distinct circuits that are hydraulically separated by a de coupler (neutral bridge). in primary secondary systems, chilled water flows through the chiller primary loop at a constant flow rate, whereas in the secondary loop, flow rate is varied.
