What is the temperature in AHU?
55 F
The AHU has an enthalpy economizer cycle and a chilled water cooling coil. The chilled water is provided by a district cooling system. The design supply airflow rate is 14,275 CFM (6.74 m3/s) with a design supply air temperature of 55 F (13 °C) and a design space temperature of 73 F (23 °C).
What is meaning of AHU?
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 is the main function of AHU?
The air handling unit (AHU) is the heart of central air conditioning. It collects outside air and room air, removes dust and other particles from the collected air, adjusts the temperature and humidity and then supplies comfortable and refreshing air-conditioned air into the rooms through ducts.
What is AHU control?
Air Handling Unit (AHU) is one of the subsystems which is the heart of a central air conditioning system. Its function is to supply conditioned air at the appropriate temperature and humidity, at the required flow rate and containing the correct proportion of outside air for ventilation.
What is the CFM in AHU?
CFM HVAC is an airflow calculation made in cubic-feet-per-minute (CFM). It's used to determine the cooling requirements of a building and, in turn, its HVAC requirements in tons. A 1,200 CFM requirement would typically need a 3-ton HVAC system.
What is 1 CFM?
ahu interview questions
CFM stands for Cubic Feet per Minute and is the most common way to measure airflow. Areas are measured in square units (like square feet). Volumes (like a room full of air) are measured in cubic units - CFM determines how much cubic feet can be moved or exchanged each minute
