One refrigeration ton equals the cooling effect produced by melting 1000 kg of ice_________________?
Show answer Hide answer
Answer: C. in 24 hours
Explanation
One refrigeration ton equals the cooling effect produced by melting 1000 kg of ice in 24 hours. This traditional unit originated from the ice-making industry before mechanical refrigeration became widespread. It standardizes cooling capacity measurements based on the latent heat of fusion for water. The latent heat of fusion for ice is approximately 334 kilojoules per kilogram. Melting one ton of ice over a 24 hour period releases a specific daily cooling energy. In US units, one ton of refrigeration equals 12,000 BTUs per hour of heat removal.
HVAC contractors use refrigeration tons to specify the required capacity of residential air conditioners. Commercial building chillers are rated in tons to communicate cooling power to facility managers. Standardizing cooling units ensures consistency in equipment manufacturing and engineering design. In 1 hour would require an impossibly massive cooling rate far exceeding standard ton definitions. In 1 minute represents an extremely high instantaneous cooling capacity not used in practice. Other timeframes like 12 hours or 10 hours do not align with standard refrigeration ton definitions.
