Danfoss has a wide variety of air conditioning solutions available for Chillers, Air Handling Units (AHUs), and Rooftop Units (RTUs). Their parts portfolio includes compressors, heat exchangers, drives, electronics and sensors, valves, and system protectors, all designed to help you boost efficiency and bring your systems in line with current and future refrigerant regulations.
In this article we will be looking at how chillers, AHU's and RTU's work together, the difference between them and the basic working principles behind each of them. Chillers, Air Handling Units and Rooftop units are used extensively within HVAC systems for commercial properties. You can watch the video on this article by scrolling to the bottom!

Water cooled chillers are typically located in the basement or lowest floor of a building. This type of chiller needs a cooling tower to reject the heat from the building. The chiller produces chilled water and pushes this around the building to Air Handling Units (AHU's) and Fan Coil Units (FCU's) etc. These units circulate air around the local space as well as the building. The air is forced across heat exchangers, containing the chilled water, which extracts the unwanted heat before the air is distributed throughout the building.
The unwanted heat, which is extracted from the air, collects in the chilled water loop. This loop circulates back to the chiller and once it reaches the evaporator, the unwanted heat will be transferred over to the chillers condenser via a refrigerant loop.
The condenser absorbs this heat and then dumps it into the “condenser water” loop which runs between the chillers condenser and the cooling tower. The cooling tower will force ambient air across the condenser water to extract the unwanted heat. The fan inside the cooling tower forces this heat to leave the system, building, and is ejected into the atmosphere. In this instance the condenser of the chiller has been cooled by water so it is a water cooled chiller.
Water cooled chillers are typically used on large commercial properties with high cooling loads, you can tell if a building has a water cooled chiller because it will need cooling towers which are typically on the roof. There will usually be more than 1 chiller and cooling tower, its not uncommon to have at least 2 or 3 or even more just for redundancy as well as variations in cooling demand.
Air cooled chillers are typically located on the roof of the building or outside e.g. in the car park. Air cooled chillers also generate chilled water which is pumped around the building to air handling units as well as other apparatus such as fan coil units etc. This is to cool the building down by picking up unwanted heat.
The air is forced to circulate around the building, local space, and will pass across heat exchangers within the AHU and FCU's. This unwanted heat is again transferred over to the condenser of the chiller from the evaporator. It is transferred via a refrigerant which loops continuously between the evaporator and condenser and is forced by the compressor. The difference with this type of chiller is that a fan blows air over the condenser which removes the heat. So in this instance the condenser of the chiller has been cooled by air, therefore it is an air cooled chiller.
Air cooled chillers are typically located outside because they need access to a lot of ambient air in order to reject the heat. This type of chiller can usually be found on medium to large commercial properties.
