Impact of Idle Controller Location for Flat Station Concept

摘要

One of the questions related to the flat station concept is the location of the idle controller. In this article the authors present a theoretical analysis in relation to idle heat loss, waiting time for domestic hot water (DHW) and volume of DHW with temperature lower than desired. The three cases considered are: idle controller in each flat station, idle controller only at the end of the horizontal pipe and idle controller at the end of the vertical pipe (Case I, II and III respectively).
