Medical Direct Expansion Air Handling Unit
Use interior wall panels that are corrosion-resistant and antibacterial.. Use dust - free, rust - free PTC electric heating. Limit coil face air velocity to 2 m/s and use stainless - steel water pans.
Choose dry steam or electrode - type humidifiers, and equip fans with frequency converters. Use disposable filters. Prioritize humidity control with an outlet limit of 75%. Include features like fan delay shutdown and control panel linkage.
Select UV germicidal lamps for relevant sections, and add ozone generators or nano photocatalytic materials at the outlet. Use micro - perforated plates for sound attenuators.

Technical Parameter
Inner Wall Material Requirements
The interior wall panels are made of anti-corrosion and antibacterial materials to meet the anti-rust requirements. resistance to disinfectant corrosion, and prevention of bacterial growth.
Electric Heating Element Requirements
The electric heating should use a dust-free, rust-free, and non-peeling PTC type or other similar performance forms.
Coil and Water Pan Design Requirements
The air velocity through the coil face should not exceed 2 m/s, and the cross-sectional air velocity should be uniform. The water pan must be made of stainless steel.
Humidifier Selection and Design Requirements
Humidifiers should use dry steam or electrode-type humidifiers, avoiding wet film and other enthalpy humidification methods to ensure no water remains in the humidifier after shutdown, eliminating bacterial growth. Fans can be equipped with frequency converters for air volume adjustment to meet various customer requirements.
Filter Requirements
Filters must be disposable and not reusable.
Unit Control Requirements
The unit control should adopt a humidity control priority scheme: the relative humidity of the air at the outlet should not exceed 75%. After shutdown, the fan should delay shutdown to ensure the coil is dried. It should also have features such as operating room control panel linkage, duty fan frequency conversion or dual-speed operation to ensure pressure difference, automatic restart after power failure, and other related requirements.
Sterilization Equipment Selection Suggestions
Ultraviolet germicidal lamps can be selected for the cooling section and the outlet section, and ozone generators or nano photocatalytic materials can be added to the outlet section. These are effective in killing bacteria in the air.
Sound Attenuator Material Requirements
The sound attenuator material should be micro-perforated plates, without glass wool to prevent glass wool fiber pollution of the air conditioning environment.
