The chiller unit has the advantages of large refrigeration capacity, precise temperature control, stable and reliable operation, and is an indispensable and important equipment in many industrial and commercial fields. With the continuous development of technology, chillers are also constantly being upgraded and improved to meet more diverse needs and higher energy efficiency standards.

According to different cooling methods, chillers can be divided into two types: water-cooled and air-cooled. Water cooled chillers use cooling towers or cooling water systems to dissipate heat, which have advantages such as high refrigeration efficiency and stable operation, but require additional cooling water systems and space. The air-cooled chiller unit, on the other hand, directly dissipates the heat from the condenser into the air through a fan, without the need for an additional cooling water system. However, it is greatly affected by environmental temperature, and the refrigeration efficiency may be slightly lower.
