Is chiller part of Ahu?
Water cooled chillers are typically located in the basement or lowest floor of a 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.
What is the difference between Ahu and HVAC?
AHU, which is Air Handling Unit is an appliance used to circulate air. HVAC is Heating, Ventilating and Air Conditioning system. HVAC is the central unit to which AHU is connected. AHU is only a part of HVAC and as such there is hardly any difference between then two.
Where is AHU used?
An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system. The basic function of the AHU is to take in outside air, re-condition it and supply it as fresh air to a building.
What are chiller units?
Chillers transfer heat away from a space that requires climate control much like a traditional split system or package unit does, but they use water (or a water solution) to do so instead of air. There are two types of chillers: water-cooled and air-cooled.
Whats a chiller unit?
A chiller (cooling water circulation device) is a general term for a device that controls the temperature by circulating a liquid such as water or heat medium as a cooling liquid whose temperature was adjusted by the refrigerant cycle. It is referred to as a “chiller” because it is often used for cooling.
What does an AHU do?
What is chiller plant?
A chiller plant is a centralized system that cools the air for a building or for a collection of buildings and provides the air-conditioning portion of HVAC systems. According to the federal government’s Energy Star website, over 35 percent of buildings larger than 100,000 square feet contain chiller plants.
Why is AHU needed?
What is Ahu (air handling unit)?
AHU (Air Handling Unit) is a cold air producing device which pump cold supply air into the central air conditioning system ductwork. AHU can produce cold air by directly cooling the air with a vapour compression cycle (this is called DX units), or by utilizing chilled water suppied from a chiller plant.
Do AHU’s have their own cooling system?
AHU’s typically do not have their own cooling system built in, instead they will be connected to a central plant water or air cooled chiller, occasionally they will use some sort of split a/c unit and you can also find these connected to district cooling networks.
What are chillers and air handling units used for?
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!
What is the difference between a chiller and an air conditioner?
Both perform the same function, which is usually to generate cold water for the air conditioning by removing the unwanted heat away from the building. The only difference is the way that the chiller discards the heat.
