How to choose a suitable thermal cower?
The criteria for choosing the best thermal talentine are simple:
- Manufacturer. An important role is played by the quality of the materials used and the assembly.
- Heating power. It depends on it: what size the room can heat the heat screw? The most primitive calculation of the required value is 1 kW per 10 m² of area of the serviced room.
- Type of heater. The main options are electric spiral, heating element and ceramic plates. Thermal tanks with a nichrome spiral are cheaper, but less safe (depending on execution). Tubular heaters (Ten) can develop high power and are more relevant for thermal guns used in unheated rooms, and not in everyday life. Ceramic heating elements are considered more reliable, safe and effective, but they are more expensive.
- The presence of additional functions. There are many options: timer, thermal regulator, remote control, rotary building, display, ionization mode and others. Which of them is really needed, and which are not particularly, everyone determines himself.
errors when choosing a floor fan and apartment.
When the time comes the heat, not everyone has enough funds and the opportunity to install air conditioning in the apartment or in the house.
over, even if you mounted it, as a rule, it cools only one room. What to do with the rest? Buy and put two, three pieces?
Therefore, most of us begin to look towards a cheaper and familiar solution. floor fans. Such devices should be in every apartment, even for those who already have a full.fledged split system.
Although it is worth recalling for those who are not in the know-the fans actually do not cool the air, but simply drive him around the room back and forth.
So due to what is the cold? Everything is quite simple. Your body reacts to the heat of plentiful sweating. Drops of moisture appear on the surface of the skin.
With their evaporation, excess heat is taken. And an extraneous breath, just the same helps to accelerate this process.
Especially if the air is dry and is not moisturized by any special devices.
By the way, do not be surprised, but sometimes it happens that the fan does not cool at all, but even performs the reverse function.
For example, if you place two ice creams on a stick, one of which will melt in a natural way, and direct the fan to the other, then, oddly enough, the second will melt faster.
This is explained by the fact that a layer of cold is formed around the sweet treat, which in some way slows down its melting. And when you direct the fan here, this layer is completely blown away. And the ice cream melts more intense.
Which of this can be drawn a practical conclusion? Since fans are not cold sources, it is difficult to get cold from them than from traditional split systems.
What floor fans to choose for an apartment and at home, and how to avoid the most common mistakes when buying, so that the device worked for you for a long time and safely?
Let’s start with the most important thing. fire and electrical safety. Do not forget that any fan is an electric device.
One careless movement or accidental circuit, and instead of cooling the apartment, you can burn it. And not all of you have special spark.shaped devices that easily prevent such accidents at the initial stage.
In case of closing the wiring on the case from the inside, it may well hit you with the current. Therefore, do not transfer the windfall from place to place in the on state.
Pay attention to the case material. On the one hand, whole metal is a great fire safety, but in terms of electrical safety, plastic looks more advantageous.
True, it is desirable that he be non.combustible. Check this in the product passport.
Also, in the documentation, be sure to look for an indication that the engine has protection against overheating. It can be a miniature thermallane that breaks the chain when the temperature of the windings is over 145 degrees.
At this moment, the impeller stops and the engine will not start again until the temperature falls. Without such protection, it is really a fire hazardous unit.
If you think that by buying the most expensive model you will get the best cooling, then you are deeply mistaken. To do this, it is not at all necessary to choose a fan with the highest price tag.
Often, even inexpensive models do very well with their tasks. Let’s clearly compare the effectiveness of the three winds in different price categories:
Cheap models are usually the most flimsy and unstable. Their noise level at maximum speed reaches 70db.
The average version knows how to do the same, but the only thing that is added in it. This is a timer and distance management.
True, his design is more stable, and the material of manufacture is moreatical. This affects the weight of the device.
Fan for the furnace on the Peltier element
Step one. We prepare all the necessary detacuetor experimented with various materials for the manufacture of a fan. The best pair for heat transfer was an old radiator from a computer, as well as a copper plate. When the radiator is heated, heat is transmitted to the dumplings element, and in order for it to produce current, on the other hand, the part should be as cold as possible. On the other side of the element is a copper plate, in theory, it should be cooled through a cylinder, which is blown by a fan, but thermal contact here is not enough.
As for the engine, it is suitable from the old drive or similar. In general, modern elements of Dumpete can produce voltage up to 12V, but it all depends on how to use them. With a small temperature difference, the voltage and current will be lower. The element of the author is designed for a temperature of 150 ° C.
You will also need a piece of pipe in the form of a corner with a nut for installation of an engine.
Step two. Prepare the bracket for installing the engine engine engine to install a copper nut. As planned, the author simply wanted to install the engine inside the nut, he measured the engine and waste the seat. But in the end it turned out that the shaft of the motor is too short and the screw clings to the cylinder. To solve this problem, it was decided to train the adapter, thanks to which the engine was brought forward.
Well, then everything is simple, we fasten the nut to the pipe and the motor is installed. The pipe is connected into the cylinder, under it you need to drill the hole.
Step third. We collect self.leakage to start assembling the structure. Peltier element should be clamped between the radiator and the copper plate. Attach the cylinder to the radiator and outline the places under the holes. Drill holes in the radiator, and then cut the thread for the screws. Now you can easily fix the cylinder on the radiator. You can try to squeeze the element between the hot and cold plate, the motor should earn if you connect it to the contacts.
Clean the radiator plane so that the element Peltier is well adjacent. Well, then install the plate on top of the element and screw the cylinder. Do not forget to connect the necessary wires. Tighten the screws so that the element of Peltier is pressed well, but do not overdo it! Also, do not confuse the cold and hot side of the element when installing, and also do not forget to decide in which direction the screw should rotate.
That’s all, homemade is ready, you can install a screw and move on to tests! Install the radiator on a hot surface, after a while it should start working! Thanks to the use of the radiator, it will be difficult to overheat the device, since the heat transfer from the furnace does not happen very efficiently. Do not forget that the dumplings element are not designed for a temperature above 150 ° C and when overheating it may fail.
You can still put the LED on the fan, as a result, it will also work as a nightlight. In general, there is no limit to perfection. That’s all, good luck and take care of yourself!
Ventilating units have a number of additional functions that make the mechanism more effective and convenient to control:
- Moisturization. Allows you to cool the room without draining air. The device increases the cost of the product, but good for health.
- Ionization. Cleans the air and restores the balance of negative ions. The ionizer is very useful for children, older people and everyone who has been at the computer for a long time. It is recommended to use such a device during seasonal diseases.
It is strictly forbidden to use the ionizer:
- In oncological diseases,
- increased body temperature,
- After operations,
- With bronchial asthma,
- in very dusty rooms,
- In case of circulatory disruption in the brain,
- with increased sensitivity or individual intolerance to ionized air.
- Turning system. The system allows you to direct flows in any necessary direction.
- Timer. Allows you to program the switching and disconnection mode of the fan.
- Hydrostat. Bathroom ventilation apparatus, which is equipped with a moisture sensor. The mechanism is automatically turned on when a certain humidity is reached. This parameter allows you to control the moisture level in raw rooms.
- Motion Sensor. Allows you to automatically turn on the ventilation system when it appears in the room. Shutdown occurs through the gap, which is set by the timer.
- Clock. They are located on the main panel of the device.
- I ventilation. The permanent ventilation mode implies the operation of the device at low speed, providing minimal air exchange. If the humidity increases, then the mode switches to the maximum.
- Spray protection. With this parameter, special models of units are produced, which are supposed to be used in rooms where there are constant spray of water. The spray protection on the device is indicated by the marking IR4.
- Check valve. The function is useful when one ventilation system is installed on the room with several rooms. Valves allow you to run the system selectively and block access to some rooms.
How to choose a good heat cementon for an apartment and at home.
When I want to make myself warmth right here and now (we are not talking about strong “drinks”), and at the same time not to spend more than 1500, the only option for consideration is the good old fan.fan or stuff.
They are especially relevant during the onset of the first cold weather and the absence of full heating.
First of all, this applies to garages. There are effective heater effective there.
But in a small room with a temperature of 10C to 20C, this is the most effective source of heating in a short.term version.
Look at the visual comparison of thermal flows from different heaters a few minutes after they are turned on.
This is small and compact, unlike oil batteries. In addition, it can be calmly included in ordinary carrying or outlet.
The only problem is to choose the right heat-cognrator so that the head does not hurt from it, and he served you for more than one winter, but for many, many years.
Some manufacturers have certificates for which their thermal cores can safely work almost around the clock (metal bushings, three protection levels, fire safety).
The vast majority of budget models have a resource of work. 3 hours a day on cold days for one, two seasons, no more.
After that, you want, do not want, buy a new. Let’s look at how a good “breeze” differs from not very good.
All thermal talents can be divided into three types:
The columns, although they look solid, but almost no one is interesting. It’s expensive, cumbersome and not mobile.
Buying a fanber, a person does not want to spend a lot of money. Its task is to get a temporary solution, saving the budget as much as possible.
Therefore, we discard this species immediately. Many are confused with air conditioning.
Yes, air conditioners can also work for heating and even fully heat the apartment or a whole house all winter.
But we are talking about heaters. Adequate wall models in the market are very few.
They are also not cheap and, as you know, are stationary heating devices. You can’t transfer such a thing from the bedroom to the bathroom or vice versa.
Therefore, table heaters are still the most popular type. First of all, due to its price.
Rarely which of the models cost more than 1700. Basically, vary from 600r to 2000r.
You do not need iPhones in the world of thermal talents, such as Delonghi.
We will choose in the normal price range.
Table thermal tape, in turn, are divided into two types:
Which is better to choose and what are their differences from a practical point of view? A spiral is always cheaper by several hundred than ceramics.
A spiral element is actually a nichrome wire that is very quickly heated to its operating temperature when the voltage is supplied to it. Heat from the wire occurs by blowing.
The temperature of such a wire reaches 800 degrees! Ceramic, or rather metal-ceramic element (ceramics there are negligible), consists of two components-aluminum and ceramics.
If you take two heaters of the same size and compare the useful area of their heating elements, then ceramics in this case significantly win. However, it heats up to much smaller temperatures (100-150C).
The most important difference between these elements is the difference in the sensations of comfort. And it is really present.
Until now, most people mistakenly believe that any heater, whether it be a douche, an oil battery or convector, all of them “burn” oxygen during work.
Nothing like this actually happens. Just all of them very strongly change humidity in the room. In other words, the air dries.
Where does the difference in sensations in the apartment come from when heated with ceramics and spiral?
The fact is that when passing the air flows through the heat cower, the dust also passes through it. Pistles settled on a hot spiral and instantly burn out.
The room appears in the room and a feeling of lack of oxygen. The air is dried with an accelerated pace.
In the global network you can find such reviews.
Daniil: “Recently acquired a douchik from the company Electrolyux. Installed at work. Warms well until there is no heating “.
Oksana: “We bought a fan home. We have been using it for two years. In winter, you can warm up when you come from work, and in the summer use as a fan “.
Warm fan devices are common household appliances for use without central heating. Divided into several types and categories. The choice should be familiarized with the recommendations and study information about the most common manufacturers.
Comparison of the best thermal fans
You learned about the advantages and disadvantages of popular models of thermal tape. The rating was compiled taking into account the main indicators of household appliances, its reliability, productivity, and I also studied customer reviews. I propose once again to compare the characteristics of the participants before moving on to the best:
|Model||Power, W)||Number of modes||Heating area (sq.m.)||Peculiarities||Price,|
|Zanussi ZFH/C-405||2000||3||25||Ceramic heater||1677-2761|
|QUATTRO ELEMENTI QE-3000 ETN||3000||2||47||Ten||3091-3290|
DIY DIY thermal core repair. diagram, causes of malfunction, thermal protection.
With the advent of the first cold weather, the main wand-up in the warming of our dwellings and offices, not bulky oil batteries or convectors, but small and compact heat talents are not becoming.
It is they who allow for a very short period of time, raise the temperature in the room at once several degrees.
However, as a result of operation, which is called fully, sooner or later comes the moment when the douche stops working. What to do in this case? Run to the store for the new model Scarlet (Scarlett), Saturn (Saturn) or Comfort (comfort) and hope that they will be much more reliable?
Because they are not very expensive. However, it is not at all necessary to buy another heat cautifier, if you can repair the available with your own hands.
In order to find the cause of the breakdown, it takes only 2 things. screwdriver and multimeter.
The most important thing is to determine whether there is contact in a particular circuit, or it is not. Let’s take a closer look at how thermal cores are arranged, how to disassemble them, what most often fails and trace the consistent chain of checking one element after another.
The first thing to do is to call and check the integrity of the power cord and all visible contacts. You may not have to climb far into the inside of the device at all, and the trouble will be on the “surface”.
To do this, unscrew and remove the lower or side cover, depending on your model.
Blower Fan Motor Won’t Shut off!- STEP by STEP Troubleshooting!
Keep in mind that the central screws should not initially be unscrewed, since the motor is attached to them.
Remove them and all the insides will be collapsed. It will be better that the engine itself sits fixed for one of the covers.
Next, find contacts where the power wires 220V come. If “lucky”, sometimes without any devices you can immediately see the burned out wiring.
Sit it in place and all repair ends. If the problem is more serious, then just probe and twitch all the terminal clamps.
Since the fan vibrates in the process, it is quite possible that some of them elementarily moved away from his place. You can detect poor contact on the terminal and according to characteristic traces of burning.
Often such defects become the reason that the heat.cumber is spontaneously turned on and off. Especially when you move it and move.
If you identify this, clean it and then wipe the site with a wool moistened in alcohol.
Further by the pliers, slightly press the terminal and put it back.
Only after all these manipulations, you can proceed to checking with measuring devices.
Switch the tester to the dialing mode, and the probes alternately check the integrity of the power wires. To do this, touch introductory contacts inside the fan and metal pins on a fork.
If everything is regular, the tester will make a sound or show zero resistance.
If you work something, for example, the fan is spinning when you are on the network, but the air is cold at the same time, then the cord is of course nothing to do with it. Its check in this case can be omitted.
In the same way, a microswitch is nicknamed, which is sometimes built into the case.
Switch its key and check that there is a chain.
These things at large currents very often fail. Repair in this case is quite simple. Two wiring suitable to it are bent and interconnected directly.
What’s Inside a Fan Heater. Fix or Salvage
The connection place is isolated by a protective cap of PPE or simple isolation.
The only negative. from now on the heat cementoer will work immediately after you stuck the fork in the outlet.
When the switch has nothing to do, check the following chain elements. By the way, do not forget about the mechanical part.
