When it comes to heat exchanger design, there’s a key heat transfer equation that needs to be considered. This equation includes the calculation of heat transferred per unit time, the overall heat transfer coefficient, the heat transfer area, the mean temperature difference, and the temperature driving the force. It’s essential to consider this equation when you’re conducting your heat exchanger design because the heat exchanger is specifically designed to provide the necessary amount of thermal energy that’s required for cooling or heating a fluid stream throughout the exchanging process.
To properly select a particular type of heat exchanger, the rate of the heat transfer is crucial to calculate. The last thing you want is to have the wrong rate of heat transfer because you could end up accidentally choosing the wrong type of heat exchanger. If the rate of the heat transfer isn’t considered during the design, the heat exchanger could end up working improperly and causing the entire appliance to malfunction or overheat. This is a problem because it can lead to unplanned equipment shutdowns, which can be expensive and even dangerous in some situations depending on what the appliance is being used for.
