About these units
TR (tons of refrigeration): Cooling capacity: the heat to melt a ton of ice in 24 h, 12,000 BTU/h.
PS (metric horsepower): European engine rating (also CV, cv or PS): 75 kgf·m per second.
Horsepower comes in several kinds: mechanical (550 ft·lbf/s, 745.7 W, used here as 'hp'), metric (PS, 735.5 W) and electrical (746 W). Cooling loads use BTU/h and the refrigeration ton (12,000 BTU/h).
