Indirect and direct refrigeration systems are typically used on LPG carriers for cooling different cargos. Indirect systems cool the cargo by a refrigerant without being compressed. In the direct refrigeration cycle the cargo is compressed, condensed and returned to the tanks. The safer method is indirect refrigeration because the cargo never mixes with the refrigerant.

Two problems that a refrigeration system could have are compressor problems or a lack of or loss of refrigerant gas.
The refrigerant used in a lithium bromide refrigeration system is water. This system utilizes the absorption refrigeration cycle, where water is the refrigerant and lithium bromide serves as the absorbent to remove heat from the desired space.
The condenser fan motor in a refrigeration system helps to remove heat from the refrigerant gas, allowing it to condense into a liquid form. This process is essential for the refrigeration system to effectively cool and maintain the desired temperature.
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.

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.
The COP (Coefficient of Performance) refrigeration formula is used in thermodynamics to measure the efficiency of a refrigeration system. It helps determine how much cooling a system can provide compared to the amount of energy it consumes.
an air conditioning system, is considered high-temperature refrigeration and is used for comfort cooling.
