Cost-effective energy-saving upgrades
Airedale International has produced a video, which can be viewed online, describing a number of energy-saving upgrades for HVAC systems. It is presented by project engineer John Cree.
HVAC equipment accounts for the single largest proportion of energy consumption in commercial buildings — at around 39%. Simple energy-saving upgrades include the following.
• swapping from AC to EC fans
• retrofitting electronic expansion valves and variable-speed drives
• reviewing refrigerant charge
• implementing sub-metering.
