Introduction to DX Air Handling Unit
A Direct Expansion (DX) air handling unit is a crucial component in HVAC (Heating, Ventilation, and Air Conditioning) systems. It works by directly expanding the refrigerant within the unit's cooling coil. When warm air from the indoor environment passes over the cold coil, heat is transferred from the air to the refrigerant, cooling the air. The cooled air is then distributed back into the space, while the heated refrigerant is compressed and condensed, and the cycle repeats. DX air handling units are widely used in various applications, including commercial buildings, industrial facilities, and residential complexes, due to their simplicity, efficiency, and cost - effectiveness.
