A chiller split system is a type of air conditioning system commonly used in commercial and industrial buildings. The system consists of two main components: an outdoor chiller unit and one or more indoor air handling units. The chiller unit cools water, which is then circulated to the air handling units, where it cools the air passing over the coils.

Chiller split systems are often preferred for their energy efficiency and flexibility. By using water as the cooling medium, they can provide efficient cooling to large areas or multiple zones within a building. They are also highly customizable, allowing building owners to tailor the system to their specific needs.

Some of the key features of chiller split systems include:

1. High efficiency: Chiller split systems are designed to be highly energy efficient, providing significant cost savings on energy bills compared to traditional HVAC systems.

2. Individual zone control: The use of multiple air handling units allows for individual temperature control in each zone of a building, providing customized comfort for building occupants.

3. Easy installation: Chiller split systems are relatively easy to install and can be configured to fit a wide range of building types and sizes.

4. Low noise levels: The chiller unit is located outside the building, which helps to reduce noise levels inside the building.

5. Flexible design: Chiller split systems can be designed to meet a wide range of building needs, including varying cooling loads and zoning requirements.

Overall, chiller split systems are a reliable and efficient solution for cooling commercial and industrial buildings. Their flexibility and energy efficiency make them an attractive option for building owners and managers looking to optimize their HVAC systems.
