VALVES
DAVID RHODES, TECHNICAL MANAGER AT ALBION VALVES (UK) LTD, EXPLAINS WHY THE HUMBLE VALVE PLAYS A MAJOR ROLE IN THE SEARCH FOR ENERGY
EFFICIENCY AND NET ZERO WINS… Small, but mighty
A s energy efficiency and carbon emissions targets for buildings tighten, engineers need to search every nook and cranny to find potential improvements and energy savings. Hydronic systems are a great place to start, and Albion has worked with clients on many retrofit projects, but we believe that it’s not always necessary to tear out an entire pipework system to find energy efficiency gains. Preserving as much of a system as possible with the introduction of modern valves can reduce the embodied carbon of the project overall and support a longer operating life of the system. The use of pressure-independent control valves (PICVs), for example, provides range ability and accurate control for heat pumps at low flow rates. Switching to 2-port PICVs where previous
4-port constant volume valves existed means that the hot water is delivered to a specific location, only where it is needed, and with no wasted energy. Introducing PICVs into an existing HVAC system also helps to stabilise the temperature range in a building, allowing the system to react to heating and cooling demands in different spaces. It is a small change but can make a big difference. Selecting the correct Pressure-Reducing Valves (PRV) configuration can help save money by optimising the pressure control installation in commercial buildings, particularly those with hybrid working patterns, where heating and cooling of empty spaces occur, wasting energy and creating unnecessary costs. Retrofits in older buildings are always more complicated. PRVs, non-return valves, and solenoid valves are good

examples of how inexpensive updates can prevent breakdowns in HVAC systems. Any technology that extends the lifetime of systems subsequently reduces the operational carbon footprint by decreasing the need to replace equipment.
