Well-designed Duco Ventilation - DC Motor Slim Series Residential Suspended Heat Energy Recovery Ventilation system (ERVs 200~400 m3/h) – Holtop

 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

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.
