An energy balance calculation is necessary to determine the heating and cooling duties in the flowsheet. An estimate of the heat content of each stream can be rapidly determined by making the following assumptions: 1. The vapor and liquid streams have ideal properties.
Heat exchangers are typically classified according to flow arrangement and type of construction. The simplest heat exchanger is one for which the hot and cold fluids move in the same or opposite directions in a concentric tube (or double-pipe) construction.
The idea of the supply of energy to compensate for the heat loss by a body, or the removal of energy to compensate for a gain in heat by a body, in order to maintain the temperature of the body is called the thermal energy balance.
1 Ιαν 2023 · Heat exchangers facilitate the exchange of heat between two fluids having different temperatures. The heat exchange involves conduction between the walls separating the fluids and convection in each fluid. The chapter starts with the discussion on classification of heat exchangers.
Heat exchangers may be divided into several categories or classifications. In the most commonly used type of heat exchanger, two fluids of different temperature flow in spaces separated by a tube wall. They transfer heat by convection and by conduction through the wall.
The heat balance [1, 7] in a heat exchanger is an application of conservation of energy principle. Ideally, the exchanger is well insulated, resulting in negligible heat transfer to/from the surroundings.
