How do you decide which fluid goes in the tubes shell of a heat exchanger?

Fluids that are or will become vapors inside the heat exchanger should generally be allocated to the shellside because they have a larger volume and a lower heat-transfer coefficient. This will maximize its heat-transfer coefficient and lower the pressure drop.

What is hot side and cold side in heat exchanger?

Temperature program This means the inlet and outlet temperatures of both media in the heat exchanger. T1 = Inlet temperature – hot side. T2 = Outlet temperature – hot side. T3 = Inlet temperature – cold side. T4 = Outlet temperature – cold side.

What fluids are used in heat exchangers?

On the liquid side of these heat exchangers, the common fluids are water, a water-glycol solution, steam, or a refrigerant. For heating coils, hot water and steam are the most common, and this heated fluid is supplied by boilers, for example. For cooling coils, chilled water and refrigerant are most common.

What fluid is in shell-and-tube?

Hence corrosive service must be kept on the tubeside. High pressure fluid is also kept on the tubeside, since tubes with higher pressure rating are cheaper than the shell with high pressure rating material. Toxic services are kept on the tubeside to increase their containment.

What fluid is on the tube side?

Fluid Velocity Fluids that need to be kept at a consistently high velocity, such as or propylene glycol for cooling, should be kept on the tube side. High speeds increase the heat transfer coefficient but are associated with potential pressure drop.

What is shell side fluid?

Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side).

What is the best liquid for heat transfer?

Water is one of the best choices for liquid cooling applications due to its high heat capacity and thermal conductivity. It is also compatible with copper, which is one of the best heat transfer materials to use for your fluid path. Water for liquid cooling comes from different sources.

What cools water or liquid?

As alcohol evaporates at a much faster rate compared with water due to its lower boiling temperature (82 compared to 100 degrees C), it is able to carry away more heat from the skin. This means for a given amount of time much more alcohol evaporates than water.

What is tube in tube heat exchanger?

The equipment consists of a single tube mounted inside an outer shell tube, so that the product medium flows counter-current through the inner tube, with the service medium around it. The unit features a fully welded construction with a bellow-on-shell tube to absorb thermal expansion.
