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.

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.
