The climatic device is used to increase air humidity. Devices are built into complex air conditioning, ventilation or placed in a room. The reasons why steam does not come out of the humidifier when turned on differ for units of a certain type. The electric humidifier can additionally work as a cooler or heater, cleaner, flavor.
Varieties of humidifiers
Depending on the method of humidification, there are nozzle devices - in them the liquid is dispersed from the holes under the influence of air pressure. In rotary types, water splashes into the surrounding area when the disc is rotated. Film types contain a wet plate in the structure, air gets moisture when it comes in contact with it. Porous types evaporate water from a loose surface in a natural way, and in boiling types water molecules separate at a high temperature of the working fluid.
Varieties of sprayers:
- traditional;
- steam;
- ultrasonic;
- spray.
Devices consume little electricity, except for the heating type. Devices do not humidify the atmosphere more than the prescribed level. Typically, to start work, you need to pour water.
Traditional
In cold installations, air is driven by the fan through a wet filter, then the moistened jets enter the space of the room. Productivity is determined by relative humidity and ambient temperature. Evaporation rate increases with decreasing air humidity and accelerates during heat.
Instrument Specifications:
- 3.5 - 17.0 l / day are evaporated;
- consume 5 - 60 W / hour.
The device “air wash” is a modified version of the traditional type and contains a rotating drum with hydrophilic disks. During rotation, the lower blades are immersed in liquid, and when moving to the upper position, they are blown by a fan. The device is filled with plain tap water without an unpleasant odor, sometimes aromatic oils are specially added.
Steam
To activate evaporation, the water is heated to a boil. The devices are equipped with a hydrostat (moisture determinant), which interrupts the operation of the heating element when a specified indicator is reached. Boiling gives an intense separation of water molecules, therefore, without a sensor, air humidity can exceed the norm.
Advantages of steam plants:
- rapid air humidification;
- evaporating, the steam is cleaned of non-volatile additives;
- the inclusion of aromatic oil in the liquid gives a pleasant smell.
The disadvantages include the high power of the device (300 - 600 W / h), but the disadvantage is overlapped due to periodic rather than constant switching on. The humidifier processes 8 - 16 l / day.
Ultrasonic
An effective humidifier forms fog, lifting water molecules from the surface under the influence of ultrasound with a power of 5 MHz from the piezo emitter. Wet particles are carried by the natural movement of flows or acceleration is imparted by a fan. Vapors contain salts, microorganisms. Some of them remain on objects after drying. Hardness salts settle on the elements of the device and shorten the life of the device.
Ultrasonic evaporators do not increase the temperature above + 20 ° C, operate silently.There are models with built-in heating elements for quick humidification, then the device consumes more power. The installation uses 7 - 13 l / day. Without a heater, the power is at the level of 40 - 50 W / h, and with a heater the humidifier takes over 125 - 200 W / h.
Spray
The nozzle type works due to high pressure. Water is supplied at a pressure of 30 - 85 bar and the particles become smaller with increasing pressure. Nozzles are placed in the room or placed in the ventilation duct opening. The latter method is used in large halls, lobbies. In household appliances, water droplets dissolve in the volume of the room, but droplet traps are used on an industrial scale.
Filters are placed in front of the nozzles and ionized because all water impurities are deposited on adjacent objects. The plants operate at low power and are characterized by high productivity.
Some models of spray humidifiers are connected to the water supply, they do not add fluid. Built-in views are difficult to mount and expensive. Due to intense evaporation, the temperature in the room decreases.
The principle of operation of devices
Devices increase relative humidity. For a residential building, this figure is 30–45% in winter and increases to 60% in summer. The principle of operation is to lift the molecules from the surface of the liquid and spray them in the volume of the room in various ways. Overmoistening has a negative effect on the human and animal organism, leads to spoilage of objects, so the devices are designed so that they can not exceed the standard threshold.
The moisture transfer rate depends on the temperature in the room, the area evaporated and the initial content of water droplets in the atmosphere. To intensify the work, a combination of the first conditions is important.
The main reasons why steam does not come from a humidifier
Causes of damage to humidifiers:
- Water entering mechanical or electrical components happens when washing the unit. The problem is solved in the workshop so that microelectronics does not fail.
- Steam does not come out of the humidifier if the generator does not work, contact plates have oxidized, and the fan has broken. In ultrasonic models, an accident occurs due to damage to the membrane.
- Wear on the piezoelectric element also causes a malfunction. This is evidenced by the appearance of a trickle of steam and its rapid fading.
In the event of a malfunction, the electrical connection (indicator light) and the presence of liquid in a special compartment are checked.
For the device of cold type
In devices, the degree of deterioration of the filters is checked, if necessary, the elements are changed. If the motor breaks down, repair is required in the workshop and engine replacement. Sometimes the engine rumbles, but the turbine blades do not move - you need to try to slightly rotate them manually. Tight mobility indicates the layering of stiffness salts, which must be removed from the parts of the mechanism in disassembled form.
With the fan inactive, steam will exit the appliance, but immediately drop. The reason for the stop is damage to the electrical wire outside or the connecting network inside.
For ultrasound machine
The main parts in such devices are the membrane and the piezoelectric element. The second spare part is not repaired, a new one is inexpensive. The diffuser (membrane) due to high-frequency oscillations generates steam from the liquid. Cleaning the membrane is recommended after 3 to 4 refills with water, while the container is washed with the addition of detergent or liquid soap.
Do not use the mechanical method of removing plaque with metal objects.
Failure to clean regularly will result in poor operation or stoppage. Sometimes a mechanism breaks down that imparts vibration to the membrane. If cleaning does not help, the membrane changes with the feeder in the workshop.
For steam
In such devices, the heater fails, while the water stops heating and boiling. TEN is not repaired and replaced by a new one.
Steam does not exit the unit due to:
- breakage of the blades;
- problems with the motor;
- violation of the integrity of the wiring.
Before removing the tank, the liquid is drained, the remaining water is soaked with a rag. Bolts are removed to remove the cover. If there is a hygrometer in the design, care must be taken not to damage the contacts. The disassembled device is tested by connecting to the network for a fan or cooler malfunction. A cold transistor indicates an inoperative generator.
For spray device
A master is invited to repair the built-in atomizer in the ventilation duct, since self-intervention is not recommended. Cleaning of parts from a layer of hard salt can be carried out personally, but the replacement of nodes is carried out by a specialist.
Terms of Use
The instructions are followed to prevent malfunctions. The liquid is poured only into the intended hole in order to increase the working life without breakdowns. Distilled water is used or piped water is allowed if specified in the instructions for use.
Terms of use:
- if the appliance is not used, water must be drained until the next time;
- Do not use other means than water;
- the device does not belong to therapeutic inhalers, so you can not inhale the vapor, leaning low;
- the capacity is filled to the set mark and not more;
- disassembly of the installation is carried out with the plug turned off from the mains.
It is not recommended to place the humidifier close to household appliances and furniture to avoid spoilage. Do not cover the device.
