Heat Exchangers Design Tools
At SACOME we are registered member of Heat Transfer Research, Inc. (HTRI)since 1998. HTRI is an internationally renowned organization that, since its creation in 1962, investigate the phenomena of heat transfer with the aim to develop much more precise and accurate design methods. Thanks to this collaboration with HTRI, the SACOME Technical Department have at their disposal the most advanced calculation tools for heat exchangers calculation.
Heat Exchangers Design Optimization
The most recent example of this ongoing improvement is the release of HTRI Xchanger Suite v8, new version with which we can optimize our designs. Some of the enhancements that this new version incorporates are as follows:
1. Determination of the fouling factor in the cooling water
One of the main uncertainties when designing a shell and tube heat exchanger for a cooling process is the correct estimation of fouling, associated with the cooling water channel. The HTRI software incorporates a new tool that allows to determine the fouling factor in water, according to its properties, such as:
2. New calculation methods for heat transfer coefficients and pressure drops, based on experimental data.
HTRI has sophisticated pilot plants that allow to parameterize and analyze the performance of heat exchangers, simulating real operating conditions. Thanks to this information, it is possible to improve the existing calculation methods for complex processes such as:
3. A new calculation engine allows to reduce the computing time.
In those applications having a high number of heat exchangers in series, multiple iterative calculations are required to be carried out to find the optimal solution for the system, since the performance of a single module can affect the operation of the rest of heat exchangers. Thanks to the new HTRI calculation engine, at SACOME we are able to further optimize our shell and tube heat exchangers designs.
The importance of rheology in the design of any processing plant is crucial since the sizing of many of the elements composing it is very dependent on this “resistance”, also taking special relevance with food products: heat exchangers, pipes, valves, pumps, mixers, etc.
To design a heat exchanger it is necessary to have certain data, such as the process flow rate, the temperature and the physical properties of products.
Hairpin heat exchangers have a more efficient and economical design compared to a multiple pass heat exchanger when the process requires a temperature crossing between the cold and hot fluid.
