Heat exchangers play a hugely important role not just here in the United States but truly all throughout the world in its entirety. After all, the data that has been gathered on the subject more than backs this up, showing that the use of heat transfer coils and everything else that might go into your typical heat exchanger is only on the rise. This data shows quite clearly this fact, as boiler and heat exchanger manufacturing revenues reached as high as $7 billion in the year of 2013 alone – and that was only just for the United States, let alone anywhere else in the world where heat exchangers and even just heat transfer coils are readily used. And by the time we reach the year of 2021, now not so far off at all, this number is expected to have grown by a CAGR of more than 8%, therefore reaching a total revenue value that exceeds $19 billion by quite a bit.
But when we’re talking about the success and overall importance of heat exchangers and the heat transfer coils that can so often be found within them, we must also talk about just exactly how these heat exchangers work. I’ve already mentioned heat transfer coils, but heat exchangers are not actually all created alike. In fact, there are four main types of heat exchangers currently in regular use both all throughout the United States as well as on a global scale. Parallel flow heat exchangers are readily and frequently used, for instance, as too are counterflow configuration heat exchangers. Finally, last but certainly not least are cross flow configuration heat exchangers and shell and tube configuration heat exchangers. Some of these exchangers use heat transfer coils, of course, but not all of them do.
Now let’s take a bit of a closer look at how exactly these heat exchangers (and sometimes heat transfer coils too, for that matter) really work, as all of the above types fulfill the same purpose but get there in ways that are often quite a bit different from one another. For instance, parallel flow heat exchangers have tube side fluid and shell fluid flowing in the same direction, with the temperatures entering the exchanger at a huge temperature disparity and at the same side of the exchanger. A cross flow heat exchanger, however, works quite a bit differently. In this type of heat exchanger, one fluid will flow through the tube while another fluid will pass around the tube perpedicularly, and this is how the heat is ultimately exchanged.
We can even split up all of the above heat exchangers into two other main categories: the multi pass heat exchanger as well as the single pass heat exchanger. The way that this categorization is determined is simply through looking at how many times the two separate fluids will pass each other. In a multi pass heat exchanger, they will pass each other more than one time – as you might have already guessed, thanks to the name. The single pass heat exchanger, on the other hand, will only see the two distinct fluids pass by each other a grand total of one time. Which type of heat exchanger you should be using will most certainly depend on a wide number of different factors, all of which must be taken into careful consideration before any type of heat exchanger is actually put into use.
Aside from heat exchangers and things like heat transfer coils, tools like portable chillers and chillers in general are really quite useful as well. And as the typical manufacturer of chillers and accessories for that chiller will likely know, chillers come in a wide variety as well. Typically, chillers will fall into one of two categories. The first is that of water cooled chillers, while the second is that of the air cooled chillers. Much like with heat exchangers and heat transfer coils and the like, the type of chiller that will ultimately need to be used will depend on a wide array of factors. Therefore, careful consideration before actual usage is once again nothing less than an absolute must for the use and distribution of both kinds.
