Refrigeration & heat exchange

Thermodynamic power cycle

Industrial machinery; Refrigeration & heat exchange

A thermodynamic cycle consists of a series of thermodynamic processes transferring heat and work, while varying pressure, temperature, and other state variables, eventually returning a system to its ...

Baffles

Industrial machinery; Refrigeration & heat exchange

Baffles are used in shell and tube heat exchangers to direct fluid across the tube bundle. They run perpendicularly to the shell and hold the bundle, preventing the tubes from sagging over a long ...

Tube length

Industrial machinery; Refrigeration & heat exchange

Heat exchangers are usually cheaper when they have a smaller shell diameter and a long tube length. Thus, typically there is an aim to make the heat exchanger as long as physically possible whilst ...

Plate fin heat exchanger

Industrial machinery; Refrigeration & heat exchange

This type of heat exchanger uses "sandwiched" passages containing fins to increase the effectivity of the unit. The designs include crossflow and counterflow coupled with various fin configurations ...

Plate heat exchanger

Industrial machinery; Refrigeration & heat exchange

A type of heat exchanger. It is composed of multiple, thin, slightly separated plates that have very large surface areas and fluid flow passages for heat transfer. This stacked-plate arrangement can ...

Tube layout

Industrial machinery; Refrigeration & heat exchange

It refers to how tubes are positioned within the shell. There are four main types of tube layout, which are, triangular (30°), rotated triangular (60°), square (90°) and rotated square (45°). The ...

Tube diameter

Industrial machinery; Refrigeration & heat exchange

Using a small tube diameter makes the heat exchanger both economical and compact. However, it is more likely for the heat exchanger to foul up faster and the small size makes mechanical cleaning of ...
