HVAC systems are designed to cover maximum loads. However, to maintain room comfort at the desired level, in 85 % of all cases the amount of energy required is lower than the designed load. This is where variable speed drives prove their value: Allowing various pumps and fans within the system to run at a speed appropriate for the actual demand reduces energy consumption by up to 60 %. This translates into a significant reduction in operating costs.
