The modern concepts for aeration of the premises regulate the construction of passive system in which the necessary fresh air for breathing and aspiration should pass through recuperator R, to recover the heat from the air that is going to be brought out.
For this purpose, we offer a complete scheme with a designation of the inflows and outflows of different gases.
The discharge side of the air recuperator actually naturally increases its flow compared to the suction side at lower pressure in the premises.
In order to check and guarantee that the discharge side manages to maintain the balance of the gas pressure balance, an individual examination of the residence ventilation system with anemometer is required.
In case of necessity of fresh air to assure the minimal over-pressure in the room with the fireplace inside is possible by activating the kitchen or sanitary aspiration, this will lead to automatically stop of the suction fan.
