It is also the configuration VMC Double Flow, equipped with 2 dc motors.sapeur3873 wrote:My burner Pellet plays him on the fan speed.
I think the fan is 12 or 24v and drive too.
it is easier to find.
This choice is quieter and more economical.
It is especially more logical to play on the speed of a fan to regulate the flow rate than to ventilate "thoroughly" and to regulate with a shutter which mainly generates WASTE of energy.
It is on econology, damn ...
I would add that the thermal regulation should then be proportional, ie between optimum fan speed and set temperature.
A "regulation" by shutter generates hot spots that are harmful to the reliability of the assembly ...

Not quite, because a fan behaves more or less like a centrifugal pump.
Consumption depends on the fluid flow.
theoretically the consumption of a pump (or blower) having no flow (suction fully closed) is not higher than the idling engine consumption.
Between a fan with asynchronous motor and regulation by component, and a fan with DC motor controller + + buck, I'm not sure that performance is favorable to the latter, or if it is, it is not probably not by much.
Is this low performance gain justifies the additional components (= production + recycling) that this solution requires?
Do not forget that a DC motor requires maintenance (replacement brush)
I know whereof I speak, I work in a factory where there is still a lot of DC motor which oblige us to maintain a large stock of brooms.
Given the great difficulty for an individual to source replacement brushes, this implies a more or less regular replacement of the engine (so again maintenance and disposal of equipment requiring recycling while it is theoretically not out = waste to use) and a risk of failure if maintenance is not assured.
This may be a deformation of a professional, but I tend to banish any DC motor for my achievements.

Sorry, I misspoke, I thought of brushless motors ... For who need a suitable controller but are maintenance and superb performance.Forhorse wrote:Do not forget that a DC motor requires maintenance (replacement brush).
... The habit of thinking "electric vehicle" therefore running on battery ... Sorry.
