A one tonne refrigerating machine means that

Question

RRB Paper · Accepted Answer

In order to express the cooling capacity of a refrigerating machine, i.e., the rate of heat removal from the refrigerated space, the common and standard unit generally used is a ton of refrigeration.

In FPS units, one ton of refrigeration is defined as a capacity to freeze one ton of water from 0°C (32 F) in 24 hours. It is the withdrawal of heat at a rate of 200 BTU/min. This equates to 12,000 Btu/hr or 12,000 Btuh or 12658 kj/h or 210 kJ/min.

A one-tonne refrigerating machine means that when One tonne of ice when melts from and at 0° C in 24 hours, the refrigeration effect is equivalent to 210 kJ/min.

A one tonne refrigerating machine means that

One tonne is the total mass of machine

One tonne refrigerant is used

One tonne of water can be converted into ice

One tonne of ice when melts from and at 0° C in 24 hours

the refrigeration effect is equivalent to

The correct answer is `No. 4: One tonne of ice when melts from and at 0° C in 24 hours`
