Modern buildings are being built tightly to improve energy efficiency. Eco-smart ERV is ideal

ventilation solution for energy efficient buildings to reduce ecological footprint and improve human

health. The energy can be saved by using DC motors and improving energy efficiency with smart

control system, to achieve eco friendly climatic experience.

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.
