Definition of the process in the design of heat exchangers The main process data that the client must define to design a heat exchanger are the flows, both product flow and service flow, as well as the inlet and outlet temperature. These parameters should verify the principle of conservation of energy Heat exchanger design includes estimation of the heat transfer area needed for known or estimated heat transfer rate, overall heat transfer coefficient and log mean temperature difference. The tube or pipe diameters and length also need to be determined, as well as the pressure drop When the heat exchanger is designed, the heat exchanger pressure drop can be calculated with different correlations determined by the characteristics of the exchange surfaces. Steps 2 and 3 are made by interdependence and iterations, as shown in the summary diagram below: HEAT EXCHANGER EFFICIENCY AND EFFECTIVENESS

Heat exchangers are devices that transfer energy between fluids at different temperatures by heat transfer. These devices can be used widely both in daily life and industrial applications such as steam generators in thermal power plants, distillers in chemical industry, evaporators and condensers in HVAC applications and refrigeration process, heat sinks, automobile radiators and regenerators in gas turbine engines
A Heat Exchanger is a device designed to transfer heat between two or more fluids (liquid, vapor, or gas) of different temperatures. On the basis of the heat exchanger, the heat transferring process can be gas-to-gas, liquid-to-gas, or liquid-to-liquid. The fluids are not in direct contact, unlike the distillation column A CHRs (0.036 m 3 /7.2 m 2) Hydronic-type heat exchanger and 12.43 m 2 /2.83 m 3 , compost reactor (CR), was designed and developed with the main objective of evaluating the design and its. Hairpin heat exchangers (often also referred to as double pipes) are characterized by a construction form which imparts a U shaped appearance to the heat exchanger. In its classical sense, the term double pipe refers to a heat exchanger consisting of a pipe within a pipe, usually of a straight-leg construction with no bends
The first step in the engineering design of a new heat exchanger is to finalize the process parameters such as - Operating temperature and pressure Design temperature and pressure Heat duty, which is the total required heat transfer rat 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. In the parallel-flow arrangement of Figure 18.8(a) , the hot and cold fluids enter at the same end, flow in the same direction, and leave at the same end . I.. A heat exchanger is a system used to transfer heat between two or more fluids.Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural.

The heat exchanger for dyeing machines influences the overall system size and system efficiency The heat exchanger designs must balance between pressure drop and heat exchanger effectiveness to achieve the desired tradeoff between system size system efficiency. This tradeoff between system efficiency and system size varies with each energy. For finding out design pressure of the system designer need to study the location of the exchanger in the process design. In a shell and tube heat exchanger, if the pressure of tube side is higher than on shell side, then low pressure side may be given a percentage increment (based on engineering design codes)

The design of earth-air heat exchanger mainly depends on the heating/cooling load requirement of a building to be conditioned. After calculation of heating/cooling load, the design of the earth-air heat exchanger only depends on the geometrical constraints and cost analysis parameter for heat exchanger design. Generally, for liquids, a value of 0.5-0.7 kg/cm2 is permitted per shell. Ahigher pressure drop is usually war-ranted for viscous liquids, especially in the tubeside.
