A tonne of refrigeration corresponds to the heat required to melt what quantity of ice at 0 degrees Celsius?

A tonne of refrigeration is a measure used in the refrigeration and air conditioning industry to quantify the cooling capacity. Specifically, it is defined as the amount of heat absorbed to melt one tonne (or 1000 kilograms) of ice at 0 degrees Celsius in a span of 24 hours.

In this scenario, the correct choice highlights that 1 tonne of refrigeration corresponds to the melting of 1 tonne of ice over a 24-hour period. This definition allows for a standardized reference point when sizes and capacities of refrigeration systems are discussed, making it easier for professionals in the field to assess and compare the performance of different systems.

The other options do not align with this definition, as they either represent an incorrect amount of ice or an inaccurate timeframe. Understanding this definition is essential for anyone in the refrigeration industry, as it is a fundamental concept in cooling capacity calculations and performance evaluations.
