sizing cooling for elevator equip room
The age of the elevator is also a factor. The control cabinet also generates heat, older elevators with relay logic and resistors for the doors are worse than the new units with circuit boards. Me I would guess on a pair of three stop elevators 1 1/2 to 2 tons would be large enough for most newer units. Oh another way to calculate.

Engine Horsepower Calculator
A typical example would be a Ferrari, which might have 800 horsepower on a 3,500 pound car. This puts the power-to-weight ratio at about 0.229. In comparison, a Ford Explorer, which sells for about a tenth of the price of the Ferrari, might have about 300 horsepower to move about 4,500 pounds. Its power-to-weight ratio is much lower (about 0.067).

Amps to Horsepower Calculator
1 Metric HP. 735.5 watts. Because 1 horsepower is equal to 746 watts, the formula above will include a division by 746 to complete the conversion. P (HP) = P (W) 746 W⁄HP. For example, let's find the horsepower of a motor drawing 8 amps at 120 volts that is 90% efficient. Assume a PF of 1. P(HP) = 8 A × 120 V × 0.9 × 1 746 W⁄HP.
