5 Facts About Chilled Water Coils
Most people are unaware of the need for balance in chilled water coils selection. The rows/fins, performance, and pricing of your coil are based on the coil you choose. It could be possible for you to save money upfront if you try to skimp on your original choice. However, you will unavoidably incur additional charges for energy. For every coil that is made, this is the case.
So let's go over some important information concerning chilled water coils. You may have seen all the many coil types we provide if you have looked through our pages. You undoubtedly want to know how these coils differ given the variety available. We've chosen one coil type and decided to delve further into it in order to assist bring some clarity.
The Thickness of Tube Often Determines the Quality
Frequently, the tube thickness has a direct impact on the coil's quality. Water that has not been adequately treated or tubes moving at too high a speed is a common installation problem. Most processes in the real world rarely go through flawless installations. A longer lifespan can be achieved by thickening the tube walls of chilled water coils.
Replacing Your Chilled Water Coil is Easy
You hardly ever need to be concerned about the performance. A 20-year-old coil needs to be replaced since it is filthy and the fin/tube bond is weak. Most likely, the coil is only using half of its potential. Your performance will be excellent the moment you start using a new coil. Your primary responsibility is to ensure that the coil physically fits in the available space. Additionally, keep in mind that smaller is always preferable to large. Smaller sizes are easier to deal.
The Fins Work Great as Filters
They are obviously not intended to serve as filters, yet they do the job perfectly. Any coil can be made more affordable by using 14 fins/inch with fewer rows than 8 or 10 fins/inch. Just keep in mind that deep coils are quite challenging to clean. Most of the time, cheap is not the best option!
Circuiting is the Tricky Part of the Coil
Simply choosing how many tubes to feed from a header is what circuiting is all about. Two guidelines apply. The water's velocity must be greater than 1 foot per second and less than 6 feet per second. The ideal speed is 3–4 feet per second. The second requirement is that you must divide the total number of tubes evenly between those in the coil and those being fed.
Fins are Aluminum For a Reason
Fins offer excellent heat transfer at a reasonable price. Copper is quite expensive, and switching to copper fins would certainly result in a two to three-fold increase in coil cost. For this reason alone, coatings are widely used.
