Energy recovery ventilation (ERV) is the energy recovery process of exchanging the energy contained in normally exhausted building or space air and using it to treat (precondition) the incoming outdoor ventilation air in residential and commercial HVAC systems. During the warmer seasons, the system pre-cools and dehumidifies while humidifying and pre-heating in the cooler seasons. The benefit of using energy recovery is the ability to meet the ASHRAE ventilation & energy standards, while improving indoor air quality and reducing total HVAC equipment capacity.
Holtop Slim Design Residential Projects Suspended Heat Energy Recovery Ventilation system unit is built in energy saving BLDC motor, F9 filter optional, high efficiency enthalpy heat exchanger.
Ideal fresh air heat recuperative ventilation solution for residential HVAC projects.
Fresh air ventilation+ Energy recovery+ Optional F9 filter air purification
, reducing running cost of cooling or heating system
1. Choose the proper installation types based on the building structure
2. Determine the fresh airflow required according to the use, size and number of persons
3. Select the right specifications and quantity according to the determined fresh airflow
Example
The area of a computer room is 60 sq. meters (S=60), the net height is 3 meters (H=3), and there are 10 per-sons (N=10) in it.
If it is calculated according to “Personal fresh air consumption”, and assume that: Q=70, the result is
Q1 =N*Q=10*70=700(m3/h)
If it is calculated according to “Air changes per hour”, and assume that: P=5, the result is
Q2 =P*S*H=5*60*3=900(m3)
Since Q2 > Q1 , Q2 is better for selecting the unit.
As to special industry such as hospitals (surgery and the special nursing rooms), labs, workshops, airflow re-quired should be determined in conformity with regulations concerned.
