Increasing the room temperature to maintain a certain level of comfort or technologically required temperature by means of assemblies of various designs, called heaters.
Among the many types of heaters there is a group of devices, whose operation is based on infrared (IR) radiation - waves generated heated using some source of energy (electricity, liquid or solid fuel, gas) emitters.
Group IR heaters Electrical includes 3 types of devices differing in type radiating element:
- halogen;
- quartz;
- carbon.
Consider one of these devices - halogen infrared heater.
Apparatus halogen heater
Heater apparatus depends on the principle of its action - generating process and transferring heat to the environment.
Halogen heaters consist of a housing aesthetic safe execution, wherein, depending on the power of the device, set one or more halogen lamps. To make the flow direction of the concentrated radiation lamp disposed in the housing on the background of heat-resistant reflector mirror-reflector. The possibility of burns from accidental contact with the existing lamp is excluded to the housing in the direction of action of the radiation protective mesh.
Halogen heaters operate on household power, compact, light weight, durable in operation and are popular in domestic use. modern performance devices have a remote control option.
Operating principle
Functions of the heating element performs a halogen lamp emitting a stream of waves in light and infrared. Such a lamp is a circular section tube (tubular flask) of approximately 20 - 50 cm, packed with halogen - buffer gas (iodo or bromo), which does not allow burnout of a tungsten filament helix filament during heating from passing through it electric current. When you turn in the spiral network instantly heated to glow, tungsten atoms begin to break away from her surface, but not in a halogen environment deposited on the tube walls, and returned back to the spiral, increasing its temperature.
Feed infrared lamp radiation, usually horizontally arranged in the housing, it heats the air not in its path, and the objects, which reaches. Thus there is not only the heating of the surface, but also internal, whereby the heated object begins to give excess heat to the environment. Thus, heating of the room is uniform, without the process of convection from a heat source and accumulation of dust on it. Power control allows to set the desired value and the small weight of the device - move it as required in other premises and to use for the zone (volumetric scattered), and local (accent on the subject) heating.
Excessive temperature rise indoors causes a reduction in the required values of the air humidity, however, while using more halogen heating devices in the room and also advisable to install a humidifier which, when the need to maintain an elevated temperature will provide optimum humidity environment. Uniform wetting is provided by the inclusion volume available in such devices ventilation function.
Types of halogen heaters
Halogen heaters are divided:
- as intended:
- Household - power to 3 kW;
- Industrial - power exceeding 3 kW;
- to execute:
- floor - the most common type, usually has wheels for easy movement;
- Wall - applied smokers small area and mounted at a height of about 1.5 m from floor, the well must be provided a base insulation made of refractory materials;
- ceiling - mounting brackets fastened to the normal ceiling level or having the ability to install in suspended construction ceiling occupy a minimum of space, installation is suitable at ceiling height of 3.0 m, heat-resistant insulation base unit required.
Requirements to the heater
When choosing a halogen heater should be guided by the following requirements:
- required capacity - for heating an area of 10 square meters. under ideal conditions (absence of drafts, heat insulation space) requires 1 kW heater, however come from 1.3 kW needs to 10 sq.m .;
- installation reliability - depending on the condition of walls and ceilings, and their carrying capacity and capabilities execution ensure safe operation of the heater is selected (floor, wall, or Ceiling);
- security outdoor performance - the heater has to be functional, that is, not only have aesthetic design, but also exclude the possibility of electrical shocks and burns - have inside reliable (ceramic, basalt) insulator and apparatus grounding;
- Internal safety device - a modern heater must be equipped with a sensor to protect against overheating, which will extend the life the heater and prevents inflammation of the device (paint, wiring, toggle switches) or others items;
- manufacturer's reliability - when you buy should give preference to products known and trusted manufacturers, since the purchase of heating low quality and dubious manufacturing instruments threatened not only by the fast escape of it from the system, but also the danger of injury or the occurrence of fire.
Terms of use
The most simple daily care halogen ceiling type devices - they are not available for mechanical damage and children, therefore, require only maintain cleanliness.
Wall and floor models must be placed on the surrounding objects at a distance of at least 1 m, placed on heaters some items to dry or warm up strongly It prohibited. Furthermore, as smoking something cover heaters, as it may lead to ignition coating, obtaining a thermal burn from contact with, or overheating of the device.
It should not be a long time to be under the influence of radiation flux in the vicinity of the heater - you can get burned. In addition, the radiation of halogen lamps are short-wave, and its lasting impact on human undesirable.
Important! If the heated floor area is significant, the best to ensure a comfortable temperature in the room will be the use of multiple low-power halogen heaters, since the use of the total capacity of the device is more negative factors.
Halogen heater desirable to acquire a lamp having a special coating weakens them glow at heating.
Advantages and disadvantages
Infrared heaters based on halogen lamps, as well as all other heaters have their advantages and disadvantages.
List the advantages:
- highest rate in effect - the effect of the device is felt within a few minutes after switching on;
- quiet operation - in the absence of ventilation heater function is absolutely silent;
- uniform heating of the room - without convection and dust accumulations;
- compact devices and their relatively low weight;
- the possibility of using the fresh air and drafts;
- affordable price range.
Deficiencies in the halogen heater is much smaller, but they still know better, so list them:
- undesirability of prolonged exposure to short-wave halogen lamps radiation on the human body;
- Glow lamps in operation.
Feature Summary halogen infrared heater with a specialization of its advantages and disadvantages lets give evaluation of the effectiveness and feasibility of its application in the conditions of life in comparison with other heat-generating appliances.
Operational Safety
As with any device that uses electrical energy to operate, a halogen heater requires security measures in operation. Some of them have already been mentioned, but it is better to bring them under one heading in a separate list of the conditions required to carry out:
- halogen housing apparatus must be earthed;
- the minimum distance from the device to the nearest object should be 1 m;
- Never leave the device is switched on at night than ever cover the heater or positioning objects on it to dry;
- avoid simultaneous switching of several powerful halogen devices in order to avoid overloading the power supply;
- concentrated focus radiation of halogen lamps on a man with a small distance can result in burns;
- Installation halogen heater performance insulation base wall via a heat-resistant material must be provided;
- radiation lamps must be kept clean, since the dust accumulated on them the risk of fire when the device is turned on;
- halogen heater operation without protective front grid is prohibited.
conclusion
Information on the operation of a particular model of the halogen heater and its detailed specifications contained in the instructions for use of the device, which is before the application of the device must be scrutinize. This will prolong the life of the heater and will protect the wearer from undesirable consequences of incorrect use.
