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. 

13th million level projects from HOLTOP

Beijing HOLTOP Artificial Environment Technology CO.,LTD,
Beijing branch sends good news.Beijing branch successfully
signed project contract of "sewage treatment plant".

The involved products are heat recovery air handling units,
total 2 sets, amount 1 million,This is the 13th biggest
single order amount over 1 million in                                             2013.

Rotary Heat Exchanger introduction (HOLTOP)

What is heat recovery wheels or rotary heat exchangers? 

Rotary heat exchanger is energy accumulator in air handling units, this products in AHU can recovery energy from indoor air when the AHU brings outdoor fresh air to indoor. The work principle can be described as a thermal wheel consists of a circular honeycomb matrix of heat-absorbing material, which is slowly rotated within the supply and exhaust air streams of an air handling system. As the thermal wheel rotates heat is picked up from the exhaust air stream in one half of the rotation, and given up to the fresh air stream in the other half of the rotation.  

In this article, I want to introduce about the HRW features of Beijing HOLTOP Artificial Environment Technology CO.,LTD.

1, Material categorization:

The wheels can be sensible wheel and enthalpy wheel. Sensible heat recovery wheel is made by 0.05mm aluminum foil. Enthalpy wheel is made by aluminum foil, which surface adopt 3A molecular sieve coating technology. 

2, The features: 

HOLTOP heat recovery exchanger range is from 500mm to 5000mm , and the product has passed EUROVENT and CE certificate.

3, Double sealing system

Unique double sealing system is installed around periphery and along with the central beam, The sealing materials are soft and dense of small friction and longer service life.

4, Purge section

In order to reach purge effect, fresh air side and return air side have at least 200 Pa pressure difference. When condition is satisfied, purge sector ensures leakage rate lower than 0.3% exhaust air to fresh air.

HOLTOP recent million level projects in end of June to July 2013

The twelfth order amount above 1 million.  In 9th July, HOLTOP Chongqing office signed contract amount reaches 1.34 million RMB, total involved in 168 pieces HRV, the project is located in Chong Qing province China, is commercial building integrated with residential building.

             

The eleventh order amount above 1 million. In 5th July, HOLTOP Wuahan office signed contract amount reaches 3 million RMB, involved 33 pieces heat recovery air handling units, the projects is commercial building located in Wuhan city, China.

The tenth order amount above 1 million. In 28th June, HOLTOP Chengdu office signed contract amount reaches 1.6 million, involved in heat recovery air handling units and heat recovery ventilator products total 54 pieces. The project is a commercial building located in Chengdu city.

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

Air Handling Units applications in construction projects

Project Name: Jinan Tianye Center

Add: NO. 264, Nan Quancheng Road

City: Jinna

Country: China

Brand: HOLTOP

Relative heat recovery air handling units (AHU) amount 1.69 million.

The projects use double stack heat recovery AHU, the function section of AHU include outdoor air fan section, filter section, rotary heat exchanger section, coil section, exhaust air section. 

Considering the cost and actual requirement of the project, the fan adopt strap driven fan, although there are options for centrifugal fan, VDF fan or plug fan etc... 

Rotary heat exchanger saves a lot of coil capacity, the recovery efficiency reach 70%

Coil adopt 4 row type tube. 

AHU structure is double skin injected with 25mm PU foaming material, ensures good thermal insulation performance. 

The thermal bridge factor reaches T2 under EU standard.

This is the sixth single order for HOLTOP that amount is over 1 million. HOLTOP is the biggest manufacturer in heat recovery ventilation industry in China. Their employees is 534 and have 24 offices and subsidiaries all over China.
