Proper functioning of domestic hot water circulation in residential buildings
(2004) 17th International Conference on Efficiency, Costs, Optimization, Simulation and Environmental Impact of Energy and Process Systems (ECOS 2004) p.1495-1502- Abstract
- The paper deals with domestic hot water circulation (DHWC) in residential buildings. Thermostatic circulation valves (TCV) of self-acting type can be used to assure proper temperature level in DHWC systems. A mathematic model of a DHWC system with TCV's in a 36 flat residential building is presented as well as results from steady-state and dynamic Simulations. The TCV design values used in simulations was based on results from laboratory tests of the number commercially obtainable TCV's (also described in the paper). The authors conclude that DHWC systems equipped with TCV's of highest gain and lowest hysteresis as achieved during laboratory test, was working satisfactory. However higher gain and/or lower hysteresis lead to larger spread... (More)
