Radiation Infrared Heating

On the one hand, this results in large energy losses due to the energy required to power the propeller, and on the other hand because only the air is heated. Objects in the room are hardly heated, so heat is not stored and freezes shortly after the heat is turned off. That is why the daily execution times for this stove are quite long. Convection heating takes place when a warm object is placed in a liquid medium, such as water or air. The thin layer of molecules in direct and physical contact with the object is heated by the conduction process and causes them to expand. As they do so, they move at a distance from the object and move the coldest and densest molecules on it.

Any object with a surface temperature above absolute zero, ° F (-273 ° C) emits infrared radiation. The temperature of the object, as well as the physical properties, will dictate the radiation efficiency and the emitted wavelengths. Infrared radiation can be compared with radio waves, visible light, ultraviolet, microwave and X-rays. They are all electromagnetic waves that travel through space at the speed of light. The difference between them is the wavelength of the electromagnetic wave.

All this makes them a great way to heat one or two people, but very bad in the heating rooms. Convection heaters, while not as efficient, heat closed spaces very well, allowing you to move without feeling cold or cold. It takes longer to heat it, but they are what you need if you want a long-term constant heating solution. Because the electromagnetic waves they emit do not interact with the air, radiant heaters do not suffer from these problems. Electric heaters and radiant heaters, also known as infrared heaters, are the most common types of heaters. Portable heaters can be used as an alternative or as an addition to ordinary thermostat heating.

The more often the air is turned in the heat zone, the more uniform the temperature in the entire heat zone will be. Likewise, the air is turned more often in the heat zone, the faster the part is heated to the desired temperature. This is already known for the warm sun and for the increasingly popular infrared sauna. Infrared heaters can convert electrical energy into almost 100% heat. That is why the statement is also refuted that heating with electrical energy must be very expensive. This only applies to obsolete heating methods with old electric heaters and heaters, but not infrared.

You also don’t have to heat the entire room as convection heaters, but you can create heated spaces where you spend most of your time and unused areas don’t get hot. The temperature of infrared heaters is efficiently controlled via thermostats. We know the radiant heat of everyday life thanks to solar radiation, which heats the objects it touches.

Higher bills: Due to rapid heat loss, standard electric heaters need to provide more heat longer, which costs more energy. More options: there are thousands of thousands of models to choose from. Inaccurate: Unless you have a real high-end model, standard convection heaters are not so good at maintaining a constant temperature. They generally use less watts and they don’t have to work very hard when there is a space with drafts. Just on / off: A drop of infrared heaters is that you cannot control the temperature quietly. This can make it difficult if you are really looking for a perfect room temperature.

Variable efficiency levels are possible with IR heating and often depend on the heat source material. The basic measure of efficiency establishes the relationship between the energy emitted and the energy absorbed, but other considerations may influence this measurement. One is the emission value of the heat source based on the perfect emissivity level of “black body” of 1.0. Ceramic heaters are capable of up to 90% or better emissions compared to the lowest values of other heaters. The infrared heaters can disguise themselves as mirrors, paints and murals; You can even hide them from the ceiling so people can’t even see them.

They take only 40% of the energy required from electric convection heaters to produce the same level of heat comfort. Infrared heaters, on the other hand, are a type of radiation heating. With infrared, this means that infrared rays are sent in a straight Terrasverwarming line to heat what gets in your way. This can be the wall of your living room, which also radiates heat, or it can be a person standing right in front of it. Unlike convection heaters, infrared heaters do not depend on airflow or hot air retention.

You can use this targeted heat zone to maintain a certain place in a warm and comfortable room. When infrared heat is chosen as the heat source, the stator needs a direct line of sight from the emitter to the part for optimal heating. The rated power of the transmitter and the distance from the transmitter to the part determine the speed at which the stator warms up. It is often claimed that a disadvantage of convection heating is that the heating speed depends on the mass and is often slower than other heating methods. With gas convection heating, it is essential that part of the air is exhausted by combustion products in order not to create an unsafe atmosphere in the heating chamber. With convection heating, the oven is set at a constant temperature and the high-speed air distributes heat to and outside the parts.

This can cause dry or irritable skin and other problems, such as attacks by the immune system and disease. It is also worth noting that if you have had a dust allergy in the past or have had problems with convection heaters, infrared heaters will alleviate all reactionary complaints. Infrared heaters can feel warmer, but better for your overall health than ceramic heaters.
