VMC on time: what are the advantages?
Point mechanical ventilation (VMC) works locally in the environment in which the recuperator is installed by alternating the flow in input and extraction.
How the VMC heat recovery unit works
In the extraction flow, the fan extracts the humid and stale area of the internal environment so that the thermal energy is stored in the heat recovery unit and is subsequently expelled to the outside.
In the intake flow, on the other hand, the heat recovery unit reverses the rotation and sucks clean air from the outside, releasing the accumulated thermal energy: in this way the renewal air is filtered, heated and introduced into the internal room.
Advantages of using timely VMC
One of the main advantages of using decentralized (or punctual) mechanical ventilation systems is that they can be used in any type of home, even in those where it is not possible to install a centralized system or where a renovation is not being carried out. complete.
Furthermore, the absence of ducts makes these devices pleasant also from an aesthetic point of view: the installation, in fact, only requires a core drilling through the wall of the size of the extraction / inlet pipe, which is completely covered by the internal mask of the heat exchanger.
The installation requires only a hole in the wall, which can be made with a particular cup tip, and an electrical connection.
One of the best-selling products in this category is Tecnosystemi's Pico heat recovery unit, to be placed on the wall in environments that require greater air exchange.
The maintenance of a heat recovery unit is also very simple and limited given that the greatest "risk" that this device can run is the clogging of the filters: this situation can be avoided by cleaning the filters with running water at least once every 90 days and replace them after the second wash cycle (cleaning could damage the filter itself)
Furthermore, electricity consumption is extremely low since all VMC heat recovery units are highly efficient even at maximum flow rate (in the order of 10 times less than a refrigerator).
The VMC systems are also equipped with a very high efficiency air filtration system, capable of also stopping pollen and fine dust present in the outside air.
Point units for mechanical ventilation must be sized carefully because incorrect sizing or excessive air flow rates and speeds can cause greater noise through the distribution network.
The VMC can be installed on any type of building but is particularly recommended in new buildings or in energy class A following a renovation.
While, on the one hand, the improvement in the performance of the building leads to a reduction in energy dispersion, on the other it creates closed and hermetically isolated environments and, consequently, unhealthy.
To have a correct ventilation rate of the building, therefore, it is necessary to install a mechanical ventilation system to check in addition to the classic natural ventilation that is obtained by opening the windows.
On Acquaclick you will find various devices for punctual mechanical ventilation of the best brands on the market.
