HOLTOP energy recovery ventilator products application in passive house

In 8th Aug. 2013, Beijing HOLTOP Artificial Environment Technology Co., LTD. support PKU-UUIC team tender who are from Peking University whole fresh air system in “International Solar Decathlon Competition” that was held in Datong, Shanxi, China. 

(Solar Decathlon, SD) is sponsored by Department of Energy of USA; 
it is a solar construction technology competition that tenders are consist of universities all over the world.

The competition pattern is designing, constructing and operating a house with full function, comfortable, well living and continuous solar house, during the competition period, all the power to run the house is supplied by the solar. This requires all products in the house must have the best energy saving effect. 

HOLTOP heat recovery ventilator, adopt latest third generation enthalpy plate heat exchanger developed by HOLTOP, the high efficiency air to air heat exchanger ensures effectively recovery energy from air when bring in fresh air to indoor. 

Mechanical Ventilation Heat Recovery work principle.

Mechanical Ventilation Heat Recovery, also known as MVHR, heat recovery ventilation or HRV.  First, what is the basic function of Mechanical Ventilation Heat Recovery? 

Aaron Song worked in HOLTOP company as sales engineer, the company has 11 years of experience in manufacturing Mechanical Ventilation Heat Recovery in China, introduced as below:

Function 1, Effective Ventilation

Introduces outdoor fresh air into indoors, meanwhile expels the indoor stale air to outdoor,

which makes you feel the comfort of nature. 

Function 2, 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 80% energy.

Function 3, 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.

Function 4, 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.

Now the above 4 features ensures good indoor living environment for residential, office etc..., at the same time, the products save energy, avoid energy wast, then how does it work? 

First, let's see what is the inside structure of the product, 

Structure of Mechanical Ventilation Heat Recovery

The Mechanical Ventilation Heat Recovery can bring in outdoor fresh air and exhaust indoor stale air because it have fan inside the product, it is the Mechanical Ventilation. 

Enthalpy Cross Flow Energy Exchanger

Then, how does the MVHR save energy? Because inside the product, it have Enthalpy Cross Flow Energy Exchanger. The energy exchanger or heat exchanger make indoor and outdoor air both go through it's air channel without mixing, but can pass energy through the ER paper between indoor and outdoor air. Below picture can illustrate it better.

Beijing HOLTOP Artificial Environment Technology Co.,Ltd, now is looking for distributors in worldwide, any interests, pls contact Aaron Song, songzilong@huandu.com.cn
