Power

hp to RT conversion

Convert mechanical horsepower (hp) to ton of refrigeration (RT). Power is energy per unit time — the rating of pumps, compressors, motors, and heat duties.

1 hp = 0.2120361 RT

Formula

To convert mechanical horsepower to ton of refrigeration, multiply the hp value by 0.2120361. To go the other way, divide by 0.2120361 (or multiply by 4.716177).

Used in practice

Rotating-equipment duties are quoted in kW or hp; heat duties in kW, MW, or BTU/hr.

Electrical input, shaft power, and hydraulic power differ by the efficiencies between them — label which one a number refers to.

Worked example. A power of 134.1022 hp is 28.43451 RT.
