secondary fluids

Secondary fluids are substances used in refrigeration and air conditioning systems, these serve to transfer heat from one place to another. Secondary fluids are different from refrigerant fluids because they are used to change the state of a substance (liquid to gas) to absorb and release heat.

The most common used in the industry are water, heat transfer liquid and steam. These fluids are used in heat exchange systems such as shell and tube heat exchangers, plate heat exchangers, and coil heat exchangers.

Water is a secondary fluid commonly used in refrigeration and air conditioning systems due to its availability, it also has a low cost and high thermal conductivity. However, water can also be corrosive and requires a treatment system to prevent corrosion and scale formation.

The heat transfer liquid is another secondary fluid commonly used in refrigeration and air conditioning systems. It is a mixture of liquids that are used to transfer heat from one place to another and can withstand higher temperatures than water.

Steam is another secondary fluid used in refrigeration and air conditioning systems. This is used to transfer heat through pipes and can be used in vapor-compression or absorption systems. Steam is efficient in transferring heat at high temperatures, but requires a steam generation system and a higher investment in equipment.

In summary, secondary fluids are substances that are used to transfer heat from one place to another in refrigeration and air conditioning systems. It is important to choose the right secondary fluid based on the needs of the system and the requirements of the process.
