HVAC air conditioning systems are required in commercial buildings as a means of producing a cooling effect. The aim is to counteract the building heat gained through the many internal and external loads. Some of the loads of these external influences include sunlight, wind, and outdoor temperature heat. Indoor factors include moisture from people, lighting, and electrical or mechanical equipment.

Chiller management systems move heat away from spaces that require climate control, just like traditional split systems or packaged units, but they do so using water (or a solution) instead of air. There are two types of chiller management system: water-cooled and air-cooled. They work similarly for most of the way before the refrigerant reaches the condenser.

Two types of chiller systems:

Cooling systems are installed in commercial buildings to achieve proper temperature control. There are two types: water-cooled chillers and air-cooled chillers. Both are refrigeration systems used to cool fluids or dehumidify air in commercial and industrial facilities.

The components that make up a water-cooled chiller and an air-cooled chiller are very similar. Each product contains an evaporator, condenser, compressor and an expansion valve. The main difference is whether air or water is used to provide condenser cooling.

1. Air-cooled chiller management system

Typically, air-cooled chillers are installed in smaller buildings because these systems require more piping than water-cooled chillers. These units also contain all components enclosed in a single cabinet, known as an encapsulated cooling unit. Connect plumbing throughout the building from a single HVAC unit to each zone. Air-cooled chillers tend to be less energy efficient, especially when the points between the base and service area are far apart. Efficiency also decreases if a single device serves multiple regions.

2. Water-cooled chiller management system

Larger commercial buildings and various building parks will use chillers to provide cooling. In these systems, chilled water is produced and then piped to other air handling units throughout the building, serving individual tenant spaces, single floors or a few floors. Separate ductwork then runs from each air handler to the zone. Chilled water based systems result in much less internal piping than all air systems because chilled water piping is used to transport heat from the point of generation to the exact point of use. Additionally, chiller-based systems are more efficient in terms of space utilization within the building because components can be located elsewhere.

Advantages of chiller management system:

Simply put, a chiller is a collection of individual components chosen to work together as a system. Although more expensive to install and more complex to operate, chillers offer advantages over packaged chillers. These advantages include higher energy efficiency, better controllability and longer life. Additionally, chiller-based systems are more efficient in terms of space utilization within the building because components can be located elsewhere.

Large commercial buildings often locate their industrial chillers in mechanical equipment rooms close to the cooling process. Some industrial chillers may be located directly next to the process, depending on the size of the chiller and compressor. Architects and engineers can design systems to place units outdoors.
