Fresh air + Energy recovery, reducing running cost of cooling or heating system
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.
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
Effective Ventilation
Introduces outdoor fresh air into indoors, meanwhile expels the indoor stale air to outdoor, which makes you feel the comfort of nature.
High efficient energy recovery
The built-in high efficient heat exchanger can recover the energy from outgoing indoor air to coming fresh air while ventilating. It can recover over 70% energy.
Perfect silence design
It is designed with the worldwide fashionable structure and manufactured by the accurate moldings. According to the principle of hydrokinetics, it achieves the perfect silent effect by using the micro-punch anechoic technology.
Air filtration and purification
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 natural ventilation in suitable climates, which can prolong the service life of the heat exchanger.
High airproof feature and easy maintenance
The heat exchanger 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 the 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.
