Features

1)Airflow from 150-1300m3/h

2)Energy recovery

3) Crossflow heat exchanger

4) Quiet operation

5)Double filters

6)Easy installation to ceiling

7)By-pass function

Introduces outdoor fresh air into indoors, meanwhile exples the indoor stale air to outdoor, which makes you feel the comfort of the nature.

High efficiennt energy recovery

The bult-in high efficient heat exchanger can recovery the energy from outgoing indoor air to coming fresh air while ventilatin. It can recovery over 70% energy

Perfect silence design

It is deisgned with the worldwide fashiionable structure and manufactured by the accurate molidings. According to the principle of hydrokinetics, it achieves the perfect silent effect by using the micro-punch anechoic technology.

Air filtration and pruification

The inner air filters are professionally designed to remove the pollutants of the incoming air, providing you the fresh and clean air.

By-pass function

By-pass function enables the unit to make antual ventilation in suitable climates, which can prolong the service life of the heat exchanger

High airproof feature and easy manintenance

The heat exchangers is connected with the equipment by the in-mold rail, and embedded with the special soft and dense sealing materials. It can be drew out  by hand and is easy to maintain. At the same time, it can ensure that tht fresh air and exhaust air are completely separated, avoiding the cross pollution.

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.
