The boiling point of a substance decreases with decreasing pressure in a vacuum.

• Boiling point is the temperature at which a substance changes from a liquid to a gas.

• In a vacuum, the pressure is significantly lower than atmospheric pressure.

• Lower pressure in a vacuum reduces the intermolecular forces holding the substance together.

• As a result, less energy is required to overcome these forces and the boiling point decrea...read more

One tonnage of refrigeration is equal to approximately 3.5169 kilowatts (KW).

• One ton of refrigeration is the amount of heat required to melt one ton (2000 pounds) of ice in 24 hours.

• It is a unit used to measure the cooling capacity of refrigeration systems.

• The conversion factor from tonnage of refrigeration to KW is approximately 3.5169.

• To convert tonnage of refrigeration to KW, multiply the tonnage by 3.5169.

There are several types of heat exchangers, including shell and tube, plate, and finned tube heat exchangers.

• Shell and tube heat exchangers consist of a shell with multiple tubes inside, allowing for efficient heat transfer.

• Plate heat exchangers use a series of plates to separate the hot and cold fluids, maximizing heat transfer surface area.

• Finned tube heat exchangers have fins attached to the tubes, increasing the he...read more
