A one tonner refrigerating machine means thata)one tonne is the total ...
1 ton = 2000lb =907kg but apprx 900kg(1kg=2.21lb)
latent heat of ice = 80kcal/kg
we know 1TR=900*80 kcal/day=72000kcal/day
=3000 kcal/hr(1day=24hr)
=50 kcal/min(1hr=60min)
we know 1kcal=4.2kj
so 1TR=50*4.2 kj/min=210kj/min.
Hope this will help u.

A one tonner refrigerating machine means thata)one tonne is the total ...
Explanation:
Introduction:
The term "one tonner" in the context of refrigeration refers to the cooling capacity of a refrigeration system. It is a unit used to measure the amount of heat removed by a refrigeration system in a given time. The term originates from the time when ice was commonly used for cooling purposes.
Option A: One tonne is the total mass of the machine
This option is incorrect because the term "one tonner" does not refer to the total mass of the refrigerating machine. It is solely a measure of the cooling capacity of the system.
Option B: One tonne refrigerant is used
This option is incorrect because the term "one tonner" does not refer to the amount of refrigerant used in the system. The cooling capacity of a refrigeration system is determined by the amount of heat it can remove, not the amount of refrigerant it contains.
Option C: One tonne of water can be converted into ice
This option is incorrect because the term "one tonner" does not refer to the amount of water that can be converted into ice. The cooling capacity of a refrigeration system is not directly related to the phase change of water.
Option D: One tonne of ice when melts from and at 0°C in 24 hours, the refrigeration effect is equivalent to 210 kJ/min
This option is correct. The term "one tonner" refers to the cooling capacity of a refrigeration system, which is equivalent to the heat absorbed when one tonne (1000 kg) of ice melts completely over a period of 24 hours. This cooling capacity is equivalent to 210 kJ/min.
Conclusion:
In summary, the correct answer is option D. The term "one tonner" in refrigeration refers to the cooling capacity of a system, which is equivalent to the heat absorbed when one tonne of ice melts completely over a period of 24 hours.
