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.

It is given by the formula LMTD = (T1 - T2) / ln(T1 / T2), where T1 is the temperature of the hot fluid, T2 is the temperature of the cold fluid, and ln is the natural logarithm.Q: What is the importance of the log mean temperature difference in heat exchanger design?A: The log mean temperature difference is important in heat exchanger design because it determines the amount of heat that can be transferred between the hot and cold fluids. A larger LMTD means that more heat can be transferred, and a smaller LMTD means that less heat can be transferred.Q: How does the log mean temperature difference affect the efficiency of a heat exchanger?A: The log mean temperature difference affects the efficiency of a heat exchanger because it determines the amount of heat that can be transferred. A larger LMTD means that more heat can be transferred, and a smaller LMTD means that less heat can be transferred. Therefore, a larger LMTD will result in a higher efficiency heat exchanger.Variables Symbol Name Unit T1 Hot Fluid Temperature °C T2 Cold Fluid Temperature °C Calculation ExpressionLog Mean Temperature Difference: The log mean temperature difference is given by LMTD = (T1 - T2) / ln(T1 / T2)CalculatorHot Fluid Temperature (°C): Cold Fluid Temperature (°C): Calculated valuesConsidering these as variable values: T1=100.0, T2=20.0, the calculated value(s) are given in table below Derived Variable Value Log Mean Temperature Difference 49.70679 Similar Calculators Lack

LMTD Calculations for Heat Exchangers

The sump, so the saturation efficiency of the pad stays relatively constant. The following equations are used to determine the dry-bulb temperature leaving the evaporative media, given pad geometry and secondary airflow information. The heat transfer in the heat exchanger can be determined with the effectiveness of the heat exchanger according. Tdb sup out = Tdb sup in - ese*(Todb - Towb ) QHx = eHx * Min( CFMsec , CFMsupply) * rair * cp air * ( Todb - Tdb sec out) After the heat transfer for the heat exchanger has been determined, an energy balance is done on the supply airside to determine the dry-bulb temperature leaving the indirect evaporative cooler. This assumes all the energy for is provided by the primary air stream so the effectiveness value includes the air-to-air effectiveness of the heat exchanger. Tdb sup out = Tdb sup in - QHxrair∗cpair∗CFMsupply The wet-bulb temperature is determined from psychrometric routines using the leaving dry-bulb temperature, humidity ratio, and barometric pressure, since humidity ratio is constant for the supply air across the indirect stage. The effectiveness of the heat exchanger is determined from a parameter estimation using manufacturer’s performance data. For the indirect evaporative cooler it was found that a value of 0.67 represented reasonable default effectiveness. Wet Coil Indirect Evaporative Cooler[LINK] The input object EvaporativeCooler:Indirect:WetCoil provides a model for a wetted coil evaporative cooler, shown in the figure below, that has water sprayed directly on the tubes of the heat exchanger where latent cooling takes place. The vaporization of the water on the outside of the heat exchanger tubes allows the simultaneous heat and mass transfer which removes heat from the supply air on the tube side. Then the moist secondary air is exhausted. The secondary air stream has its own fan. Wet Coil Indirect Evaporative Cooler The process that the secondary air goes through, A to C on the following figure, is a path of simultaneous heat and mass transfer, but it does not follow a line of constant enthalpy as in the direct stage. The process is not adiabatic due to the heat gain from the supply air flowing through the tubes of the heat exchanger. Secondary Air Process – Indirect Wet Coil Evaporative Cooler The wet coil heat exchanger can have a higher stage efficiency than the dry coil due to a higher heat transfer rate on the outside of the heat exchanger tubes. Over the operating lifetime of the heat exchanger, the vaporization taking place on the heat exchange surface can leave mineral deposits that will decrease the effectiveness of the heat exchanger. Efficiencies of the Indirect Stage[LINK] In an indirect stage of an evaporative cooler, the secondary or wet side air stream acts as a heat sink for the supply air. The efficiency of the indirect stage is given as the effectiveness of the sensible heat exchange, eHx, and the saturation efficiency on the wet streamside, ese. These are expressed as: eHx = qqmax = Csup(Tsupin−Tsupout)Cmin(Tsecin−Tsecout) , ese = Tdbsecin−TdbsecoutTodb−Towb.

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.
