Is it true that, within reasonable limits, the larger the heat exchanger area, the better? Is this statement correct? The reason is that the heat exchange area is large, so Δtm is relatively small; in other words, the temperature difference between the inlet and outlet is smaller, allowing for better control and more stable temperature of the medium being heated Is this statement correct? If that’s not the case, how can we improve the temperature stability of the medium after heating it with steam through a heat exchanger? Thank you!
That’s more or less what it means, but you also need to take into account the thermal stability of your materials, as well as the cost of the heat exchangers and the available installation space. A larger size certainly makes it easier to control the temperature, but there will definitely be various issues in other aspects.
That’s more or less the idea, but once the heat exchange area reaches a certain size, increasing it any further doesn’t improve heat transfer; instead, it only increases the pressure drop of the fluid, which is not cost-effective
