Today, most heating systems in apartment buildings are based on the recycling of liquid heating medium through heating pipes and radiators. The construction costs of the system are relatively high, in addition to which, due to the relatively high temperature of the heating medium, natural thermal energy sources such as solar energy or geothermal energy cannot be used. The thermal energy of the exhaust air cannot be used either.

On the other hand, in the heating of larger commercial apartments, systems are known in which the heating takes place with inflatable warm air, which is preheated with exhaust air in a heat exchanger.

In order to apply the air heating principle, also to residential apartment buildings, the invention is based on a system for heating a residential apartment building with exclusively blown hot air, which system includes a collector duct 5 96 6 4 The apartment-specific branch ducts are fitted with heating radiators, which are connected to the apartment-specific thermostats.

In a previously proposed air heating system for apartment buildings (FI patent publication 51012) has been proposed for use. a specially designed heat exchanger to control the temperature of the apartment-specific sub-air flows by directing the flow in more or less contact with the heat exchanger surfaces. However, this requires a cumbersome heating-in supply duct system, as the separate ducts in the apartments have to be routed centrally via a central heat exchanger. This disadvantage can be avoided by the solution which is the starting point of the invention, in which an adjustable heat exchanger device is not used at all, but the power of the heating radiators of the apartment-specific partial air flows is controlled in a known manner by apartment-specific thermostats.

The object of the invention is to further develop said type of air heating system so that its heating power control can be made more convenient and energy-saving than before.

To achieve this object, the system according to the invention is characterized in that the supply air duct is branched after the heat exchanger into facade-specific duct sections with separate and individually adjustable air preheating coils, and that the apartment-specific air heating coils are electrically or domestic hot water. Only after these preheaters does the heating air be led through the apartment-specific radiators. In this case, the heating demand per apartment remains smaller and its variation limits are lower, so that the heating per apartment can be carried out without significant additional costs with a low-cost electric or domestic hot water heater. Temperature differences and heating demand across the building can vary considerably, for example when the sun is shining on one side of the building, with the other side in the shade, but due to facade-specific or hot water heaters can be used.

In the following, the invention will be described in more detail with reference to the accompanying drawings, in which Fig. 1 9664 shows a heating system of a residential apartment building according to the invention in a vertical diagram.

Figure 2 shows a schematic vertical section of the system corresponding to the left half of Figure 1.

Figure 3 shows a vertical section of a detail of the system at the intersection of the vertical and horizontal flues.

Figure 4 shows a plan view of one floor of a residential apartment building with a heating system according to the invention for two apartments.

Referring first to Figure 1, the overall operation of the system will be described. The fan 1 sucks the supply air flow through the heat exchanger 2. A vacuum cleaner 3 connected to the exhaust air duct 4 sucks the exhaust air from the apartment-specific exhaust points 5 and blows it into the outside air. The heat exchanger 2 is used in a manner known per se to recover the heat of the exhaust air preheated by the supply air flow. The supply air flow is divided per facade into at least two sub-flows 6 and 7, which have their own air heating coils 8 and 9. The adjustment of the heating coils 8 and 9 is carried out per facade by means of thermostats placed on opposite sides of the building. This facade-specific heating control is important due to the fact that, for example, in the sunshine, the temperature difference between the opposite facades of a building may be considerable. In this way, heat consumption is equalized and the need for apartment-specific heat control is reduced.

In the next stage, the facade-specific heating air flows 6 and 7 are divided into apartment-specific sub-flows 10, which are equipped with electric or domestic water heaters 12, which are controlled by apartment- or room-specific thermostats 14.

Figure 2 shows a preferred embodiment in which the supply air flow 6 is distributed to each apartment in its own risers 6A, 6B, 6C, which are connected to the respective cavities 10A, 10B and 10C of the intermediate bases 15A, 15B and 15C formed of hollow core slabs.

Figure 3 shows the connection of the vertical supply flue 6 to the horizontal duct 10 of the cavity plate by means of a pipe curve 16. The heating coil 12 4 59664 can be placed in the lower part of the wall in connection with the pipe curve 16. The heating air supply openings 17 can be placed in the intermediate base plate next to the wall, e.g. below the windows, as shown in Fig. 4.

The temperature measurement of the system can be done, for example, so that in the heat exchanger 2 the supply air is heated to + 5 ° C, in radiators 8 and 9 to about + 35 ° and with apartment-specific after-heating radiators the temperature can be further increased to about 5-10 ° C.
