Overview of air handling units 1 Insulation performance air treatment unit wall panels are generally sprayed with double-layer color steel plates or cold-rolled steel plates (some of the inner side plates of the bottom plate are made of stainless steel ),Most of the insulation materials in the middle are polyurethane foam or flame retardant centrifugal glass wool.If you look at the thermal conductivity, water absorption and density alone,Both are good insulation materials.However, due to the operation of the air handling unit,High-speed operation of sending and returning fans,The vibration of the box is relatively large,The quality of glass wool is light,Large gaps in the structure are prone to fall off due to long-term vibration,Resulting in a sharp increase in thermal conductivity,Lose the role of insulation,Thus causing the panel condensation of the air treatment unit,The air supply temperature is high.However, it is not necessary to use polyurethane foaming to have a good thermal insulation effect,For exa
