- The principle of operation and designHowever, heaters, whose principle of operation is based on the emission of infrared waves, have become popular for some time. They deserve their popularity thanks to wide advertising in all media. The manufacturer claims that the device is absolutely safe to use in everyday life, and is also an economical device. This is manifested in the fact that infrared radiation emits more heat than conventional instruments for space heating. In this case, the advantages of this heater is not so much, but they overlap the disadvantages of the usual. In this article we will tell you that infrared heaters are harmful or not. The benefits and harm of devices will be described below in the article.
The principle of operation and design
To understand the benefits or harm, or both, it is necessary to know the principle of the operation of the device itself, its design and technical parameters.
As is generally known, all local heating devices emit IR waves, which are a type of electromagnetic flux. However, the difference between an ordinary battery and our device lies in the length and intensity of these flows, which is a significant difference. As an example of natural heating and light - our sun, it is the most powerful emitter of infrared waves on the planet. Being under the sun for a long time can cause burns and other unpleasant consequences.
The infrared heater is not the Sun, the radiation is thousands of times weaker, the length and frequency of the waves is less, which means it is safer. The principle of work consists in uniform heating of surrounding objects, with the help of directed beams into the space of a room. Surrounding objects, or rather the surface, heats up depending on the heating of the device itself. The number of waves grows depending on the degree of incandescence of the heater.
Infrared heaters are divided according to peak temperature and wavelength. Here are some examples:
- Devices emitting long waves - approximately from fifty to two hundred microns;
- Radiant waves of medium length - from two and a half to fifty microns;
- Radiating waves of a short range - from seventy six hundredths to two and a half microns.
Also divided by the effect on human skin, that is, the penetrating ability of the waves under the skin. It depends on the frequency and intensity of IR waves, which are divided into three types: IR-C, IR-B, IR-A.The letters from C to A indicate the effect of infrared rays on human skin, that is, depending on the wavelength, the permeability of the latter to the layers of the skin increases. When the glow element reaches a certain temperature, depending on its indicator, the number of emitted waves will vary and some will be more, others less. However, it is known that the higher the temperature, the higher the concentration of short waves. Most often this is silent, and to the uninformed user it will be a novelty.
It is also worth paying attention to what material the device is made of. It is known that black shades absorb infrared radiation more than others, and also reflect them quite well, while distorting them. Therefore, it is worth avoiding devices made of metal or black plastic, for this is best suited ceramics, which has optical reflectors.
Harm and benefits of
So, here we come to the main issue that interests many users or just people who are going to buy an infrared heater for use, whether the device has a negative effect on their body.
Since the discovery of IR radiation, scientists have tested and studied for years how it affects the human body as a whole, its benefit and harm. As mentioned above, the sun is the largest and most aggressive source of radiation, and it was this that served as an example for experiments. So, the effect of radiation comes mainly through the skin and eyes. Depending on the number of IR waves, their effect also changes.
The main harm is caused by infrared rays to the skin, they dry out it, and the epidermis does not have time to isolate the segment that moisturizes the surface. Therefore, long time to be under the influence of the heater is harmful, because it can lead to burns of varying degrees and skin diseases. It is strictly not recommended to turn on the device to its full capacity when you are under direct influence, especially with devices that emit short and medium wavelengths. All these indicators also depend on the person himself, on his susceptibility, which you should pay attention to, so that you do not blame the manufacturer for the deception. Each person can withstand a certain number of any waves, not only infrared, so you need to be careful and follow all the instructions that came with the device.
Further, according to the degree of harmful effects on the human body, eyes are harmed. Often, a long stay under the influence of direct IR rays negatively affects the internal structure of the eye. The effect is thousands of times weaker than the sun, but again it all depends on the physiology of people who use the device. Therefore, it is strongly recommended not to install infrared devices near workplaces where there is a direct impact on the eyes. This applies to manufacturing enterprises and offices. Violation of these points is a direct violation of safety in operation.
Therefore, in order to avoid harmful effects, you need to know a few things:
- The device is not intended to be used for a long time, since its working principle is radically different;
- Instruments using short and medium wavelength ranges are intended for use in large indoor and outdoor environments;
- If you purchased the device, then if you please, follow the safety instructions during operation, so that no further questions arise.
So, with the harmful factors familiar, now find out the useful side of the infrared heater.
First, unlike solar, infrared radiation of the device has no radioactive effects and ultraviolet radiation. This is a huge plus that makes this device convenient and safe, of course, if you have correctly selected the device and are using it correctly.
Secondly, as mentioned above, the device heats all the objects in the room, which is similar to solar exposure to the surface. Only therefore, when using this device, you will feel that the room warms up evenly, and not as from ordinary heaters, that is, in sections.
It is also worth noting that the main advantage of these heaters is the fact that they do not overdry the air, destroy microbes and do not allow dampness to spread, thereby creating coziness and comfort in the home.
Devices are great not only for heating rooms, but also used on the street. Many devices are used for medical and prophylactic purposes, for quick and effective heating of certain parts of the body. Useful in the prevention of colds and inflammatory diseases.
So, from the above, we can draw the following conclusion: infrared heaters have more positive qualities than negative ones, it is rational to use them both indoors and outdoors, however, devices using a long wave range are recommended for home use.
We hope this article has helped you in deciding whether infrared heaters are harmful to health or not. Use the devices according to the instructions, and we assure that the device will bring you great benefits.
