Hearth as a heating device Excessive energy, excessive heat can have an equally adverse effect, as well as the lack of it. along the horizontal plane shows the intensity of solar radiation incident on the Earth's surface at the equator and the latitude of Helsinki. Analysis of these data shows that the Helsinki since mid-May until early August, receives more solar energy, ie heat than the equatorial zone. Therefore, in the summer time, the problem created by the presence of excess heat. And if that type of focus is a good heating equipment in the summer you can not use it at all - it can only serve as a dressing room. The second circumstance, which ¬ PoE must be considered when choosing source as heating devices, is to determine what a person expects from the heat. In Finnish, the word "heating" is used to describe two significantly different concepts; heating to raise the temperature of air (for example, the fall in the bath or in a summer house); heating to maintain the no-change the temperature of the air (for example, in the main house). To improve air temperature requires that a certain power (kW), though the greater in magnitude than willing to quickly raise the temperature of air in the room. In practice this is achieved either by using a large flame (when it reaches a large thermal radiation), or as a result of high surface temperature heating device. To maintain a constant indoor air temperature requires little power (less than 1 kW, usually 0,3-0,6 kW per room), but it must equally influence for a long time. This means using a very small flame, the heating device of small size and low surface temperature (in the range 35-40 ° C). This is easiest achieved by means of large massive hearths, heat thoroughly once a day or two. Some heaters are suitable for raising the room temperature and to maintain a constant temperature of air in it. Examples include heating and thermal storage center, which has a connector to the chimney in the upper part (with the focus on summer mode) and at the bottom (using the source as a heating furnace in the heating season). In addition, there are various additional devices to the stoves and fireplaces, with which you can quickly get a lot of heat (to raise the temperature of air in the room). When these devices are closed, the focus turns to thermal storage device (for maintaining constant temperature in the room). These various alternative designs will be discussed in more detail in the discussion about the outbreak and applied them in a snap. The operation of the hearth as a heating device (used in order to improve the temperature or its sub-holding constant) is the most important when choosing the type of fire. |
