As i found: A measure of the effective cooling capacity of a refrigerator, expressed in Btu per hour ot in tons, where one ton of capacity is equal to the heat required to melt 2000 pounds of ice in 24 hours or 12000 Btu per hour.

There is a emissions sticker under the hood on the left side that will tell you the capacity of the refrigeration system
The absolute capacity of a condenser is the maximum amount of heat energy that it can absorb or release under ideal conditions, usually measured in British Thermal Units (BTUs) per hour or in tons of refrigeration. It is a critical parameter in determining the cooling capacity of a refrigeration system.
There are 12,000 British Thermal Units (BTU) in a ton of refrigeration (1 ton of refrigeration = 12,000 BTU/h). This measure is commonly used in the refrigeration industry to quantify the cooling capacity of a system.
To calculate the size of a compressor in refrigeration, you need to consider factors such as the refrigeration load (heat to be removed), desired temperature range, type of refrigerant, and efficiency of the compressor. Use the formula: Q = m * Cp * ΔT, where Q is the cooling capacity, m is the mass flow rate of refrigerant, Cp is the specific heat of the refrigerant, and ΔT is the temperature difference. You can then select a compressor with a capacity equal to or greater than the calculated cooling capacity.
Nominal cooling capacity is the suppliers or manufactures equipment rated capacity based on the test conditions. Test conditions always varies to design conditions, therefor in most cases the Nominal cooling capacity is more than the design or actual cooling capacity.
Capacity of airconditioning is expressed in terms of "tons" of refrigeration (TR). 1 TR is the equivalent of heat removal at 4500 Kcal/hr.
Tonne of refrigeration(TR) is the practical unit of refrigeration effect.Tonne of refrigeration(TR) is defined
Sludge in a refrigeration system can lead to reduced system efficiency, decreased cooling capacity, and potential damage to components such as the compressor. It can also cause blockages in the system, leading to uneven cooling or system breakdown. Regular maintenance and proper filtration can help prevent the formation of sludge in a refrigeration system.
Balancing a refrigeration system involves adjusting various components such as the expansion valve, evaporator, and condenser to ensure proper operation and efficiency. This process helps optimize the system's performance by ensuring that each component is working at its designed capacity and that the system is thermally balanced.
Non-condensable gases in a refrigeration system can lead to reduced system efficiency and cooling capacity. They can cause increased pressure, temperature, and energy consumption, which can result in decreased cooling performance and potentially damage system components over time.
Refrigeration was created in 1859
