In an Air Handling Unit (AHU), cooling coils are essential components for cooling the air before it is circulated into the space. These coils can be designed in various ways depending on the application, energy efficiency, and cooling needs. Here are the most common types of cooling coils used in AHUs: 1. Chilled Water Cooling Coils… Read More »types of cooling coil in ahu
The key difference between an AHU (Air Handling Unit) and an FCU (Fan Coil Unit) lies in their design, functionality, and the scale of their applications within HVAC (Heating, Ventilation, and Air Conditioning) systems. Here's a detailed comparison: 1. Function 2. Components 3. Application 4. Air Supply 5. Maintenance 6. Energy Efficiency
The main function of an Air Handling Unit (AHU) is to condition and circulate air as part of a heating, ventilation, and air conditioning (HVAC) system. It ensures a controlled indoor environment by managing the air's temperature, humidity, cleanliness, and ventilation levels. Key Functions of an AHU: Typical Applications: The AHU plays a critical role in… Read More »what is the main function of ahu?
Aluminium rotary heat exchangers are normally used in commercial buildings where temperature efficiency is most important. Sorption rotors are used when moisture is to be recovered for both summer and winter operations and epoxy rotors are used when there is a risk of corrosion attack, e.g. in coastal climates. The rotary heat exchanger recovers both heat… Read More »Different types of rotary heat exchanger
Rotary heat exchangers What is a rotary heat exchanger? The short answer: a rotating wheel with a multitude of small ducts made of aluminum is what a rotary heat exchanger consists of. The extract air is warm and heats the ducts which transfer the heat to the colder supply air. The temperature efficiency of balanced supply… Read More »What is a rotary heat exchanger?
The wheel is built up by a matrix that consists of two foils, one flat and one corrugated; together, they create channels for the air to pass through. The wheel is rotated by an electric motor and belt drive system. In one half of the rotation, the exhaust air from the inside space flows through the… Read More »How does a rotary heat exchanger work?
