The units sizes range from small modular units of 2000 CFM to large custom built units of 30000 CFM and higher. Larger air handlers that condition 100% outside air, and no re-circulated air are known as makeup air units (MAUs). These are commonly used in places

2024年3月26日 · To size an AHU cooling coil, first, determine the required airflow. Then, identify the on coil and off coil temperature of the cooling coil and use the psychrometric chart to find the enthalpy difference. Finally, multiply 4.5 by the airflow and the enthalpy difference to get the AHU cooling coil size.

HU modules are linked by fast connectors. The AHU control system can manage the chilled water coil, hot water coil, DX cooling and/or heating coil(s) (in conjunction with ERQ/VRV) of single or multiple refrigerant circuits (up t. just a convenient feature for installers. It ofers cost-saving benefits as there is no need for expensive ad.

The AHU Selection Worksheet uses sensible load, latent load, and total load to provide the remaining variables to select air handling units. Use this tool for small single-zone fan coil units and split systems up to large, industrial-type air conditioning systems.

The document aims to select appropriate AHU sizes based on the supply air requirements for each zone. This document contains dimensions and specifications for air handling units (AHUs) for different zones in a building project.
