A Plate Heat Exchanger (PHE) is a type of heat exchanger used to transfer heat between two fluids, without the fluids coming into direct contact with each other. It consists of a series of closely spaced metal plates with channels or gaps between them. The fluids flow through these gaps, and heat is exchanged between them through the plates. What is Significance of NTU in Heat Exchanger? The NTU (Number of Transfer Units) is a crucial parameter used to analyze and design heat exchangers, including plate heat exchangers. It quantifies the effectiveness of the heat exchanger and provides valuable information about the heat transfer performance. It simplifies the analysis and design process, making it easier to understand and optimize heat exchanger performance.

The guessed value is adjusted until convergence is achieved.Published relationships for F in graphical form are available for most geometries of shell and tube heat exchanger and a range of geometries of crossflow heat exchanger (see guide to references at the end of this section). The size of the graphical presentations rarely allows values of F to be estimated to better than two significant figures. This accuracy of estimation is consistent with the overall accuracy of the mean temperature difference approach and the lack of compliance with the underlying assumptions. Attempts to improve the accuracy in the estimation of F values are therefore unlikely to produce significant benefits for heat exchanger designers.An alternative method of presenting mean temperature difference information is known as the effectiveness—NTU method. This method is based upon exactly the same initial assumptions. The heat transfer behavior are presented as a relationship between effectiveness, E (defined in a similar way to P), the ratio of the thermal capacities of the streams, R, and the number of heat transfer units, NTU which as calculated from the expression(6)where ()smaller is the smaller of ()1 and ()2.Unfortunately, the parameters E, R and NTU are again not consistently defined and any user should check the definition used by the supplier of data and apply those definitions when using the data.Effectiveness-NTU information is typically presented graphically as the relationship of effectiveness against NTU for various values of R. Figure 2 shows a typical relationship. This shows that the effectiveness tends to zero as the NTU tends to zero and the effectiveness tends to a maximum value as NTU becomes large.Figure 3. Typical relationship between E and NTU for various values of R (Based on Single E-shell with any even number of tube passes).Users of the effectiveness-NTU technique are not required to calculate the log mean temperature difference when carrying out design or rating calculations. For design calculations, E and R can be calculated from the mass flowrates, specific heat capacities and inlet and outlet temperatures. The value of NTU can be read from the graph for the chosen design of heat exchanger and used to calculate the required surface area. In rating calculations, the surface area, mass flowrates and specific heat capacities can be used to calculate R and NTU. The value of E can be read from the graph and used to calculate the rate of heat transfer in the heat exchanger. It can therefore be argued that the effectiveness-NTU method can be used for rating calculations without the need for an iteration. In reality, since heat transfer coefficient will change with temperature, it is still likely that an iterative calculation will be required.Effectiveness-NTU relationships are generally presented graphically and may be used to produced estimates to two significant figures. Again, because of deviations from the underlying assumptions, this level of precision in the calculations is consistent with the precision of the overall method. An attempt has been made to produce a single algebraic expression with a number of variable coefficients. Plate Heat Exchanger Calculator.

The Carotek Heat Exchanger Selection Guide provides a model of the heat exchanger sizing and selection process.Heat exchangers are used throughout industrial processes whenever heat needs to be transferred from one medium to another. Understanding how to size and select a heat exchanger benefits both productivity and the bottom line. Types of Heat ExchangersBy its most basic definition, an industrial heat exchanger transfers thermal energy from one fluid to another without mixing them. Heat exchangers can be generally classified into a few main types:Shell and Tube heat exchangers consist of a shell enclosing a number of tubes. Because they are widely used, these versatile heat exchangers are generally well understood. The shell and tube design helps these heat exchangers withstand a wide range of pressures and temperatures.Plate and Frame heat exchangers are compact, efficient products designed with a number of stacked heat transfer plates clamped together within a frame.Gasketed Plate heat exchangers feature titanium or other nickel alloys for accurate fluid temperature control for heat recovery. These designs are often used for food or sanitary applications.Brazed Plate heat exchangers are constructed without gaskets, and they are suited for greater range of pressures and temperatures. Available in materials like copper or nickel, these corrosion resistant heat exchangers are suitable for many applications.For any given application, there is usually more than one heat exchanger design that could be used. A starting point for heat transfer solution sizing and selection is to compare models that fit the temperatures and pressures required for the process. The best type of heat exchanger depends on design parameters, fluid characteristics, space, and budget.Main Criteria for Heat Exchanger Sizing and Selection Function that the heat exchanger will perform (whether condensing, boiling, etc.) Pressure limits (high/low), which may vary throughout the process, and pressure drops across the exchanger Approach temperature and temperature ranges (which may vary throughout the process) Fluid flow capacity Materials requirements. Conditions like sudden temperature changes or corrosive media may require special materials. For a gasketed plate heat exchanger, the gaskets must be compatible with the fluids in the unit. Thermal fluid characteristics and product mix. If the heating or cooling fluid is susceptible to fouling, a corrosion resistant material may be needed. Location. Some exchangers may require cooling water, steam, or hot oil, and they may be relevant options only where these utilities are available. Footprint. Space limitations and layout may also affect which heat exchanger models are suitable. Keep in mind that lower approach temperatures generally correlate to larger units. Maintenance requirements. Depending on housekeeping procedures, it may be useful to choose a design lends itself to easy cleaning. Ease of repair or inspection may be a factor as well.Generally, more than one heat exchanger model will work for a given application, so additional criteria may help in evaluating the best fit. Consider factors like future scalability, overall cost to purchase and operate, and efficiency/carbon footprint to narrow the options.Importance of Sizing a Heat ExchangerOnce a heat exchanger design is selected, the most efficient.

Size depends on operating conditions. For example, if operating temperatures vary seasonally, both the winter and summer cooling (or heating) load must be calculated. The most efficient plate exchanger model is the smallest model with the same plate corrugation that is capable of handling the flow in both seasons.Thermodynamic equations can help arrive at the best solution, where flow, temperature, and pressure drop are all within acceptable limits. Due to the number of dependent variables in heat transfer solution sizing and selection, complex equations are often used for selecting the optimal solution. Heat exchangers can often be tailored, and specifications like the size and number of plates are often customized for the application.Carotek is an authorized distributor of Standard Xchange heat exchangers, and Carotek engineers are specially trained to assist with finding the optimal heat exchanger to meet your specifications.

Plate Heat Exchangers design : calculation method

R, the ratio of the thermal capacities of the two streams and P (sometimes known as effectiveness, E), the ratio of the achieved heat transfer rate to the maximum possible heat transfer rate. These parameters are typically defined as(4)and(5)whereUnfortunately, there are no standard definitions of R and P. Users of the F method should always check the definitions used by any supplier of F value information and apply identical definitions when using this information in heat transfer calculations. This variation of definition can lead to problems when comparing data from different authors.Values of F are frequently presented as graphs showing the relationship between F and P for a range of values of R. Figure 2 shows a typical relationship. The figure shows that F always tends to 1 as the amount of heat transferred reduces to zero. The figure also shows that for any given value of R, there is typically a maximum achievable value of P. The value of F changes rapidly as P approaches its maximum value. Because of this sensitivity, heat exchanger designs are rarely developed near the maximum value of P and are typically restricted to conditions which give values of F greater than 0.8.Figure 2. Typical relationship between F and P for various values of R (Based on Single E-shell with any even number of tube passes).The F factor can be used for both design and rating calculations. For design calculations, the mass flowrates, specific heat capacities and required temperature changes will be specified. R and P can therefore be calculated directly. The design engineer will need to check that the required value of P is less than the maximum value of P for the specified value of R. The value of F can then be found from the graph. The combination of the log mean temperature difference and F gives the mean temperature difference and with an estimate of the overall heat transfer coefficient, the required heat transfer area can be established. If the required value of P is greater than the maximum value for the specified value of R, a different type of heat exchanger must be considered until a feasible design is found. A simple countercurrent heat exchanger will always be able to achieve any design requirement but may be physically impractical.For rating calculations, the geometry of the heat exchanger and its heat transfer area, the mass flowrates and the specific heat capacities of the streams and hence the overall heat transfer coefficient and the inlet temperatures will be defined. It will therefore be possible to calculate R but not P. The rating is estimated using an iteration which may start by guessing a heat transfer rate and calculating the exit temperatures, the log mean temperature difference and P and then using the figure to estimate F. The resulting heat transfer rate is then calculated from F, the log mean temperature difference, the overall heat transfer coefficient and the heat transfer area. The guessed and calculated heat transfer rates are compared and
