How Does A Central Chiller System Work?

Posted by Senho Machinery on December 25th, 2020

First of all, why is there a need for a chiller system? A typical building (office, hospital, school, etc.) generates quite a lot of heat from people, equipment, and sunlight—and even the chiller itself produces heat. A chiller helps maintain a comfortable environment that is conducive to working, education, and living.

There are different types of chiller systems: central chillers, scroll chiller, brine chillers, screw chillers, and much more. This article focuses on one particular type: central chillers. How do they work?

There are two major types of central chiller systems: air-cooled and water-cooled.

•          In air-cooled central chillersystems, the hot refrigerant gas from the condenser is cooled and condensed using ambient air. It turns into a liquid and is then recirculated. The cooling process can be significantly shortened using additional air fans. However, the heat needs to go somewhere, and it is often discharged. It makes the site considerably hot, but during cold seasons, this could come in handy. The heat can warm the facility in winter, which saves a lot of money.
  
  Air-cooled central chillersystems offer the advantage of being portable. They can be used for small buildings, and their installment and maintenance costs are cheap. One downside to this type is that it could be quite noisy because of the cooling fans.

•          Meanwhile, a water-cooled central chiller systemuses water from a cooling tower which is connected to the condenser, cooling the refrigerant. The expelled heat turns into a liquid and is circulated back into the system. Generally-speaking, water-cooled chillers are more effective. While they can be used for small-scale cooling, these units are mostly used for medium to large-sized facilities with sufficient water supply. They are also quieter than air-cooled central chillersystems. However, this system can be quite expensive when it comes to installation and maintenance costs. It also requires a steady water supply and periodic water treatment.

Both central chiller systems have their advantages and disadvantages. In the end, it all comes down to product quality. Make sure to get a central chiller system that comes from a leading manufacturer. They should have plenty of years of experience and can provide a wide range of products. An ideal cooling equipment manufacturer should also cater to multiple countries worldwide. This means you can take your business almost anywhere, and they can be there to give you the best central chillersystem.
