| How cooling tower, AHU and chiller work together |
How a chiller, cooling tower, and air handling unit work together to provide air conditioning (HVAC) to a building. In this article, we will discuss this topic to understand the basics of HVAC power plant.

| How a Cooling Tower Chillers and AHU Work Together |
The main components of the central refrigeration plant system are:
· cooler
· Air handling unit (AHU)
· Cooling tower
· Sneakers
The chiller will usually be located in the basement or on the roof, and it depends on the type of chiller used. Rooftop chillers are typically "air cooled" while basement chillers are typically "water cooled" but both perform the same function, which is to generate chilled water for air conditioning by removing unwanted heat from the building. The only difference is how the cooler rejects unwanted heat.

| Air cooled chiller and water cooled chiller |
Air cooled chillers and water cooled chiller Air cooled chillers will use fans to blow cool ambient air over your condenser to remove heat from the system, this type does not use a cooling tower. You can learn more about this system and watch the video tutorial by clicking here. In the rest of this article we will focus on water chillers and cooling towers.
The water-cooled chiller has two large cylinders, one is called an evaporator and the other is called a condenser.
Frozen water:
The chiller evaporator is where the "chilled water" is generated. The “chilled water” leaves the evaporator at approximately 6°C (42.8°F) and is pushed into the building by the chilled water pump. Cold water flows the full height of the building to each floor in pipes called "risers." These pipes are called risers, regardless of whether the water flows up or down inside.
Chilled water is branched from the risers to smaller diameter pipes that reach the Fan Coil Units (FCU) and Air Handling Units (AHU) to provide air conditioning. Les AHU et les FCU are essentially des boîtes avec des ventilateurs à l'intérieur qui aspirent l'air du bâtiment et le poussent à travers les serpentins de chauffage ou de refroidissement pour modifier la température de l'air, puis repoussent cet air dans le Building. Chilled water enters the AHU/FCU and passes through the cooling coil (a series of thin pipes) where it absorbs heat from the passing air. Cold water is heated, and the air that passes through it is cooled. When the cold water leaves the cooling coil, it will now be warmer at approximately 12°C (53.6°F). The hot cold water is then returned to the evaporator, via the return riser, and once it enters the evaporator, a chiller absorbs the unwanted heat and moves it to the condenser. The chilled water will then begin to cool again, ready to flow through the building and collect more unwanted heat. Note: Chilled water is referred to as “chilled water” whether it is hot or cold.
Condenser water:
The chiller condenser is where unwanted heat is collected before being sent to the cooling towers. A refrigerant passes between the evaporator and the condenser to move all the unwanted heat. Another loop of water, called "condenser water," passes in a loop between the condenser and the cooling tower. The refrigerant recovers heat from the "chilled water" loop in the evaporator and transfers it to the "condenser water" loop in the condenser.
Condenser water enters the condenser at approximately 27 °C (80.6 °F) and will pass through it, collecting heat along the way. When it comes out of the condenser, it will be about 32 °C (89.6 °F). Condenser water and refrigerant never mix, they are always separated by the pipe wall, heat is simply transferred through the wall. After the condenser water passes through the condenser and picks up unwanted heat, it travels to the cooling towers to take that heat with it and returns to the chiller ready to collect more heat.

| Location of cooling towers |
Cooling tower:
The cooling tower is typically located on the roof and is the final destination for unwanted heat in the building. The cooling tower contains a large fan that blows air through the unit. The condenser water is pumped to the cooling towers and sprayed into the air stream. Cold ambient air will enter and come into direct contact with the condenser water spray (in an open cooling tower), allowing heat from the condenser water to be transferred to the air and that air exhausted to the atmosphere. The condenser water is then collected and returned to the chiller condenser ready to collect more heat. Check out our special tutorial on cooling towers here.
