Are you looking for a new chiller for your workplace? Are you confused about which chiller to buy such that it fulfills your needs? Taking such an important decision like this one is a daunting task for any engineer or a business owner. The wrong decision can waste both time and money.
Let’s discuss this issue in detail.
Before actually visiting the market and buying a chiller, it is vital to determine the kind of chiller you need. You can either go for a water-cooled chiller or an air-cooled one. If your goal is to upgrade an existing unit, you will have to replace it with the same kind of chiller. On the other hand, if you are about to handle a new installation, you need to spare a moment to reconsider your options.
You need to understand the difference between a water-cooled chiller and an air-cooled chiller. Remember, these chillers are named upon the kind of condensers they use. An air-cooled chiller has a self-contained system and requires no outside units. Unlike a water-cooled chiller, an air-cooled chiller is easy to install.
When it comes to water-cooled chillers, they need a cooling tower along with a cooling tower supply pump to cool the water. If you have a cooling tower on the plant, your best option is to go for a water-cooled chiller.
Now that you have chosen between the two types of chillers, the real game begins.
Choosing between scroll and screw chiller is yet another challenging task. If you are looking for a smaller chiller, go for a scroll chiller. However, if you need something bigger, choosing between the two can become a little tricky. Here are some things that you need to consider.
Choosing the suitable evaporator for your chiller is a crucial decision to take. It is wise for any application beyond 20 tons to go for a DX Shell and tube evaporator instead of a brazed plate. A brazed plate evaporator cannot handle fouling, although it has copper brazing and stainless steel. Shell and tube evaporators, on the other hand, have a longer lifespan and better durability.
