The condenser supply sub-loop incorporates one or more cooling towers connected in series or parallel, flow splitter and flow mixer together with a circulating pump. The default sub-loop also includes a scheduled temperature setpoint manager which is pre-defined to control the off-plant temperature at a constant 29°C.
The demand sub-loop incorporates a flow splitter and flow mixer in order that the loop can be connected to condenser components such as a water cooled chiller.
The graph below (reproduced with permission from CIBSE) illustrates the vapour compression cycle. The condenser process takes the fluid from saturated vapour (point 5) to saturated liquid (point 6) on the graph below.
