Do you have a need for calculating plate heat exchangers? The corrugation on the plates causes high turbulence, which results in substantially higher heat transfer efficiency. The amount of heat given is equal to the amount of heat taken. Then pipe sizes, pipe lengths, and a number of bends can be determined. A heat exchanger is an energy exchange system (in the form of heat) between a hot and a cold fluid. This process is explained below for a 2 concentrical tubes heat exchanger in counter-current. However, in the food industry, this information takes a special relevance: the viscosity of the food fluids can abruptly change with the temperature (even more for low temperatures), being common that the product has a non-newtonian behaviour, in which the viscosity depends also on the process velocity through the heat exchanger. If one of the media is glycol 30%, it is usually necessary to increase the number of plates by 20%. By Steven Holzner . Heat exchangers A heat exchanger is a piece of equip-ment that continually transfers heat from one medium to another. Hexact - heat exchanger design software. Example: Calculation of Heat Exchanger. Heat exchangers are used in industrial processes to recover heat between two process fluids. A = wall area (m 2, ft 2). The program uses the calculated heat transfer area to make design of heat exchangers of different types. However, if we wish to discretise the heat exchanger into several increments and calculate the LMTD for each of them, there are some values unknown at a first glance, being necessary to execute a process of iteration and convergence. That together with an estimated overall heat transfer coefficient allows calculation of the required heat transfer surface area. This is usually achieved by plotting the normalized parameter Q/ITD = Q/(Th,i− Tc,i). This equation must be discretised along the heat exchanger into a suitable number of sections: the heat transfer efficiency between the fluids varies along the heat exchanger as, among other reasons, the thermal properties change with temperature and complex thermal phenomena take place inside the heat exchanger. To solve a thermal problem, we need to know several parameters. H = overall heat exchange coefficient (kW.m 2.K-1) S = area of the heat exchanger (m 2) Depending on the flow path (tube, annular space, etc.) Heat exchange by conduction can be utilized to show heat loss through a barrier. By applying the heat exchange equation, it is possible to obtain the required exchange area. SWEP B8TH, B26H, B120) of the exchanger is available with a different number of plates (10, 20, 30, ...).

Often manufacturer’s choose to present heat exchanger performance in terms of the inlet temperature difference ITD = (Th,i−Tc,i). For a circular tube, being k thethermal conductivity of the metal, it is defined as: As the heat exchanger is operating, a layer composed of the impurities of the product (it happens in a similar way with the service side) is being deposited on the surfaces being in contact with the fluids. This calculator will help determine which exchanger has enough heat transfer capacity for your system. It is taken for granted that the media are not mixed together. The calculated heat exchangers are sorted according to price and pressure losses and an exchanger suitable for the given project is selected. However, as it is necessary to choose a length of the tube available on the market, L: if this length is less than the theoretical one, then a set of heat exchangers, n, is required to be placed in series: Anyhow, it’s always advisable that the exchange area is higher than the theoretical one, depending on the uncertainty when determining the thermal properties of the fluids, the fouling resistances or the heat transfer coefficients.

The Model Numbers shown in the calculator are only a partial listing of our standard products. Design of shell and tube exchanger: A shell and tube heat exchanger is one of the most popular types of exchangers due to its flexibility. There are three primary classifications of heat exchangers according to their flow arrangement. Once the process has been established and the thermal properties of the fluids have been modelled, the task of defining the heat exchanger starts itself. The Heat Exchanger Calculator is based on Effectiveness (ε) – NTU method. The inlet temperatures are known and outlet temperatures are to be determined. 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. Heat Transfer Calculator. 18. To that end, the next heat transfer equation is applied, where Q is the thermal exchange duty, U is the global thermal exchange coefficient, A is the exchange area, and LMTD is the logarithmic mean temperature difference. For complex products, SACOME offers its clients the possibility to do rheological tests, starting from a little sample, in order to get the properties in an accurate way. The Number of Transfer Units (NTU) Method is used to calculate the rate of heat transfer in heat exchangers (especially counter current exchangers). This is obtained from the process data already settled for the product, that will usually be processed through the inner tube. Heat exchanger duty is calculated as: Q = ε * Q Max. If two objects having different temperatures are in contact, heat transfer starts between them. Heat transfer through a surface like a wall can be calculated as. The following equation represents the heat lost by the new mass of coffee, m 1: And here’s the heat gained by the existing coffee, mass m 2:.
