BSRIA has completed a research project on the most energy efficient design solutions for re-circulating heating and chilled water pumping systems.
The project was carried out in collaboration with BRE and the industry partners including Danfoss, Frese, Belimo, SAV UK, Andrew Reid & Partners, Crane Fluid, Herz Valves and Grundfos.
The project results have been published in a BSRIA's Design Guide to Energy Efficient Pumping Systems.
Essentially this guide provides recommendations for building services designers on the design of energy efficient pumping systems. However it is invaluable to a broader group including manufacturers, contractors and end-users who will benefit from being able to design, select and manage more efficient systems.
The recommendations presented in this guide focus on:
- Pump energy fundamentals
- Pipe sizing
- Pipe layout
- System control issues
- Commissioning issues
In summary, our findings show that a pumping system capable of realising the maximum energy savings will have a number of different properties. Some of these include:
- Having a variable flow system with a pump that varies its speed to match the operating load conditions
- A controlled pump speed so as to maintain pressure constant across the most remote DPCV controlled sub-branches
- Pipes sized as large as possible in order to minimise their resistances
The Guide is available to purchase from BSRIA Bookshop.
