Two walk-in coolers have equal floor area, but one has frequent door openings and receives warm product each day. What should its load calculation include?

- BFloor area alone; the operating differences are irrelevant.
- COnly the compressor motor nameplate horsepower.
- DOnly the quantity of refrigerant currently in the system.

Why A is correct
Door traffic and incoming product add loads that equal floor area cannot capture. Calculate the design load before selecting equipment; this does not independently determine refrigerant charge.
