The choice of a fireplace must not be made only on aesthetic criteria or power consuption. It’s important also to evaluate if the heat distribution in the house is efficient, smooth and silent. So today we will explain why, in a forced convection fireplace, Ecofit is the perfect double inlet centrifugal fan to meet these needs.
How heat is distributed?
The hot air is distributed by:
- Natural convection: it is the oldest method, that of the old fireplaces, where air movement is given simply by the difference in air temperature (hot-cold), making a slow and not necessarily uniform heat, but absolutely silent.
- Forced convection: it is the versatile method, that of the latest generation fireplaces, because it allows you to enjoy the benefits of natural convection system and simultaneously it accelerates the heating times of the adjacent rooms. To obtain this it’s necessary that the fireplace is equipped with a centrifugal fan. The application of the fans doesn’t increase the thermal power of the device, but increase the volume of distributed air, greatly reducing the heating time.
In a centrifugal fan, the air flow is diverted from the impeller: the fan is placed in a structure called “scroll”, able to condition the flow in a precise direction and to increase the pressure, at the expense of the flow rate. The air is then diffused more rapidly in the environment, through air filtration grids.
The problem of noise
As we said above, in a home fireplace installed, one must consider also the bother linked to noise of its internal components.
Of a fan, you perceive both the direct sound of the motor and the air displacement caused by the blades, but also the noise caused by the reflection of the environment in which the fan is placed: usually the channeling walls inside the fireplace in part absorb noise, but in part they reflect it, causing the annoying glare phenomenon, that’s more accentuated as the channeling walls are smooth and hard.
The noise of a fan, therefore, is more noticeable the greater the rotation speed of the blades is. Moreover, the greater the rotation speed of the blades is, the greater the vibration generated by air vortices on the funnel walls is, especially when the fireplace has been built with little accuracy.
Why do prefer the centrifugal fan Ecofit?
The double inlet centrifugal fan Ecofit, distributed (exclusively for Italy) from Fandis, finds its ideal application in forced convection fireplaces. This fan is equipped with a motor with double shaft mounted on elastic supports which allow to minimize the mechanical transfer of noise generated by the rotation of the rotor and reduce the possibility of its unbalance.
The main features of Ecofit range products are high efficiency, low noise and strong design. How is this possible? Thanks to an accurate design, which ensures a proper rigidity to the combined structure in an assembly system that reduces the risk of vibration and resonance.
All Ecofit models comply with the ErP Ecodesign-Directive, adjusted to new energy efficiency benchmarks.
The advantages of the centrifugal fan Ecofit Fandis:
- double-shaft motor mounted on elastic supports
- noise minimized
- rotor unbalance reduced
- high energy efficiency
- strong design
- risk of vibrations and resonances reduced
- complies with ErP Ecodesign Directive
