Does reducing off-cycle losses improve steady-state efficiency?

Reducing off-cycle losses does not improve steady-state efficiency because steady-state efficiency is determined during periods of steady operation, where the system runs continuously without cycling on and off. Off-cycle losses occur when the system is not actively heating or cooling, which is when the equipment is in a standby mode, resulting in energy losses that do not factor into the steady-state operation of the HVAC system.

Steady-state efficiency focuses on how efficiently the system operates during its normal running conditions rather than during periods of inactivity. While reducing off-cycle losses is important for overall energy efficiency and can lead to lower total energy consumption, it does not directly enhance the steady-state efficiency rating of the system itself.

Thus, the concept revolves around understanding that the efficiency metrics applied here are distinctly focused on active operation rather than the behavior of the system during off-cycling phases.
