The heating unit is the device for heating of inhabited, industrial rooms. Today gain popularity vozdushno heating units.
Types
Heating units are distinguished by the form the heat carrier:
- water,
- electric,
They have the identical principle of work.
Heating units can also be floor, suspended.
Traditional heating systems often happen material-intensive, often are not always effective. The fact is that heat from such heaters goes upward, air below so remains cool.
There are and vozdushno heating units forcing warm air to the room. Such device consists of the air heater and the axial (centrifugal) fan.
Heating coils in units (water, steam, electric) – metal tubes. In them there is heat power source. If the electric power is used, as heating coil serves TEH (tubular electric heater). In the device there are rotary blinds (blades) which give the chance to regulate the direction of air.
Principle of operation of the unit
The operation principle vozdushno of the heating unit consists in the following: air is forced by the fan in the air heater. There it heats up, and at the exit there is stream of warm air. Temperature is controlled by the thermostat, the device stops operation of the device when certain value is reached.
Heating units often use Vozdushno for heating of industrial rooms, also apply them at offices, movie theaters, shopping centers, other buildings with the significant big area. It is possible to use them and for heating of cottages.
Units establish under ceiling or lift on height of 3-4th m (in various points). The current of air is heated from top to down. It is provided with necessary turning angle of blinds, body inclination.
Technical characteristics
Let's consider technical characteristics vozdushno of heating units on the example of the KCK 3-10 brand. The device is used in services of heating, conditioning, air ventilation. Characteristics:
- performance - 6300 m³/ч;
- air heater volume - 7.1 l.;
- thermal power - 139.6 kW.;
- weight - 64 kg;
- the area of heat exchange - 29.5 sq.m;
- dimensions - 1227х575х180 mm.
KCK 3-10 is made according to state standards, ready devices are subjected to strength tests, tightness. Heatelements are made of resistance welded steel pipes.
Advantages
Vozdushno of heating units carry the following to advantages:
- fast mounting of devices;
- fast warming up of rooms;
The unit distributes the warmed-up air evenly on all building. Availability of valves blinds allows to send stream of warm air to any points of rooms.
