THE QUALITY OF THE HEATED AIR IN THE ROOM
Rational heating is not only about maintaining an appropriate and uniform temperature throughout the apartment, but also on this, that the heated air does not contain components harmful to health. Therefore, among the household and sanitary facilities in the apartment, devices that provide heating and ventilation of the room come to the fore. These two factors must not only provide the desired temperature, but keeping fit for health, in terms of ingredients, air. With high air pollution, which occurs in cities and larger estates and industrial plants, airing is of great importance. Poorly ventilated buildings are exposed to moisture, and thus the rapid rotting of organic bodies included in building materials. Even machines operating in dusty air or wet conditions deteriorate quickly. Objects of art, like pictures, fabrics etc.. must be properly stored, so that they do not get damaged. Various gastronomic items, e.g.. cakes, meat products etc., as well as cotton products require a certain amount of humidity to keep them in good condition, air composition and temperature.
As you know, air, apart from oxygen and nitrogen, contains other components, of which there is a greater or lesser amount of water vapor. The amount of water vapor, what air can absorb, increases with increasing air temperature. Therefore, while the air heats up, it absorbs water vapor from living organisms and objects, which are in his sphere. This is what drying is all about. In humans, this is manifested by drying out of the mucous membranes, wilt in plants, while furniture in too dry air cracks and warps.
Air, which we breathe and consider clean, always contains a lot of dust. We can observe it in a narrow ray of the sun, which is raining through the window. Most of the dust particles are of organic origin.
Dust particles, as they heat up, they become drier and more volatile, and at the temperature of the heating devices above 80 ° C is already starting to burn. This is evidenced by black streaks on the wall above the central heating radiators. Light, volatile dust particles heated to combustion, they pollute the air. It is very harmful to your health: causes headaches, feeling tired, often an even more serious condition. So if the surface of the furnace heats up too much (ponad 80 ° C), it is in a short time that the air in the room becomes polluted, and therefore unhealthy.
That is why the problem of heating is so closely related to ventilation. It is possible to achieve the same air temperature in the room with a small, solid-fire, strongly heating stove, as well as with a larger furnace heated to the permissible limits, i.e.. to a temperature below the dust burning temperature. However, in terms of health, the air heated by the furnaces will be better, because there will be no burnt dust particles in it.
The Polish climate requires housing heating in the period of approx 200 days of the year. The area of Poland is divided into 5 climatic zones, whereby, depending on the lowest external temperatures, we calculate the heat loss in the room accordingly. For our conditions, apartment stoves are suitable, which heat up evenly, do not exceed the permissible temperature and keep warm for a long time. Therefore, a well-built tiled stove is the most appropriate method of local heating of living quarters.
