Adequate indoor air quality(IAQ)involves many factors depending on the local situation and climate.Health issues like breathing problems can arise from air containing dust,pollen,or other contaminants.A poor indoor environment can also damage buildings.
Commercial(non-residential)air handling units tend to be larger units designed for buildings like offices,hotels,and airports.The challenge is to achieve a comfortable IAQ with as little energy input as possible.This means that pressure drop should be low(less fan power is needed)and thermal/humidity efficiency high(less energy consumed for heating/cooling/humidity control).
Depending on the geographical region,the primary purpose of the heat exchanger shifts between heating or cooling(and maybe also dehumidifying)the outdoor air before it enters the building.
The air handling unit(AHU)is at the center of a ventilation system.At a minimum,an AHU includes one or several fans in each air channel to move the air through the unit.Filters on either side remove dust,pollen,etc.,and protect the fans.Finally,a heat exchanger transfers the required heat or humidity from the exhaust air to the supply air.
Implementing an air-to-air heat exchanger is an excellent way to utilize what is usually considered waste heat.An air-to-air heat exchanger will use the temperature difference between the supply and exhaust air to increase the system’s efficiency.There are two types of air-to-air heat exchangers:rotary and plate heat exchangers.
The type and exact configuration depends on the application.Both types are made of aluminum,which has excellent properties such as efficient heat transfer capabilities and an extraordinarily long life span.We offers numerous design variables and options for each product,enabling perfect fit and performance in every AHU.
