Humidifier solution
The main function of the humidifier is to increase and adjust the indoor humidity, adjust the indoor temperature, eliminate static electricity, beautify the skin, and maintain health. Especially along with the improvement of people's living standards, air-conditioning is widely used, leading to the breeding of air-conditioning diseases such as skin tightness, dry mouth and tongue, cough and cold. Some humidifiers can also release a large amount of negative oxygen ions during the atomization process, which can effectively increase the indoor humidity, moisten the dry air, and combine with the smoke and dust floating in the air to make them precipitate, which can effectively remove paint smell, musty smell, Smoke and odor make the air fresher.
1. Comparison of advantages and disadvantages of 3 household humidifier solutions
At present, the common humidifiers on the market have many different working methods, and the purpose is to increase humidity, which can be described as "different routes lead to the same goal". Therefore, in addition to choosing a brand, consumers should also consider the type. According to different working principles, humidifiers can be divided into three categories: thermal humidification type, ultrasonic humidification type, and fan humidification type.
1. Heat humidification type
The working principle of this kind of humidifier is simple, that is, to boil the water, turn the water into steam and distribute it to the room, so as to achieve the purpose of humidification. One of the biggest advantages of this type of humidifier is that it must be aseptic humidification, with extremely high purity, it is indeed a "pure humidifier". Due to the principle of this humidification method, the generated water vapor can also rise to a sufficient height indoors, so that the range of benefits of this humidifier is further expanded. In addition, water vapor is actually invisible to humans. The white "water vapor" that can be seen in the past is just water mist spreading in the air. Another advantage of this type of humidifier is that it is easier to maintain and it is easy to achieve a large amount of humidification.
The main disadvantage of this type of humidifier is that it consumes a lot of power. Generally, it needs two to three hundred watts. After one night, it will consume 3 kWh or even more. Due to the sufficient power supply in foreign countries, most of them use this type of humidifier.
2. Ultrasonic humidification type
Ultrasound refers to "acoustic" waves with frequencies beyond the audible range of the human ear. It is still a mechanical wave that propagates in objects in the form of longitudinal waves. The working principle of the ultrasonic humidifier is to use a transducer to convert electrical energy into mechanical energy, atomize the water with a quick vibration in the water, and disperse it into the air to achieve the purpose of humidification in this way. The main advantage of this type of humidifier is that it saves electricity. Due to the high efficiency of the transducer and the circuit, the power consumption of this type of humidifier is only 30 to 40 watts, and it does not use 0.5 kWh of electricity overnight. It is indeed very economical. Its humidification work is also very intuitive, and the white water mist makes people look very comfortable. However, its humidification capacity is not too large, and it is generally suitable for small bedrooms. Due to the limitation of the working principle, although the water mist looks good, the benefit range is not large.
The main disadvantage of this type of humidifier is frequent maintenance. Generally, it needs to be maintained every four or five days, because a layer of green moss will be formed on the transducer soon. If it is not cleaned, it will directly affect the atomization. The mist is gone! Fortunately, each manufacturer provides cleaning agents for random sales, and the cleaning work is not troublesome, and it is easy to master. Another disadvantage of this type of humidifier is that it is easy to form secondary air pollution. If the cleaning is not in place and the water quality is poor, it will be harmful to human health. It would be better to use cool boiled water or pure water, so that it is not easy to leave white powder in front of the humidifier. According to an authority on medical equipment, the secondary pollution caused by inadequate cleaning of medical ultrasonic atomizers (which are consistent with the principle and composition of household ultrasonic humidifiers) is closely related to the aggravation of respiratory infections in children in winter.
3. Fan humidification type
A typical feature of this type of humidifier is the use of a low-noise fan inside the humidifier. It works by using a super absorbent item like a towel to first absorb the water, while the fan continuously forces the air to remove the water. , dissipated into the air.
This type of humidifier is generally exquisite in design, can maintain the balance of the water surface, has no unbearable noise, and has a large humidification capacity. This method also makes the humidification process relatively pure, so some manufacturers also call it "pure" type humidification device. Its main advantage is that it saves electricity and can partially purify the air due to forced air circulation. The disadvantage is that high-quality fans must be used, so the price is higher, and maintenance work is required, but it is not as frequent as the maintenance required for ultrasonic humidifiers.
To sum up, the three types of humidifiers have their own advantages and disadvantages, and consumers can choose according to their own specific conditions. If the room is large and facing the street, and you don't care about the noise, you can choose the pure direct evaporation type. Ordinary families may wish to try the ultrasonic wave, and it would be better to use distilled water or cold boiled water if conditions permit. Families with better conditions can choose the heat evaporation type, which is convenient and trouble-free.

This is an isenthalpic humidification method in which the filter, pump unit, water tank, and control box of the humidifier are installed in the workshop or machine room, and the spray system (nozzles, pipes), etc. are installed on the top of the workshop. This humidification method is to pressurize the tap water through the humidifier main unit and pass through ultra-fine filtration, then spray it out at high speed through a special nozzle atomization, forming 5-10/a n water mist particles, which exchange heat and moisture with the flowing air. Absorb the heat in the air, vaporize and evaporate, increase the humidity of the air, realize the humidification of the air, and at the same time play the role of cooling and controlling dust. The high-pressure spray humidifier can independently cool and humidify the workshop and spray liquid.
2. Wet film evaporative humidifier
The working principle of the wet film evaporative humidifier for the central air conditioner is very simple. Water flows down evenly from the top of the wet film through the steam trap along the corrugated surface of the wet film, so that the wet film is evenly moistened from top to bottom. When the dry heat When the air flows over the surface of the wet film, it will exchange heat with the moisture in the wet film. The moisture evaporates into water vapor and enters the air, increasing the humidity of the air, thus turning the dry hot air into clean and moist air.
Wet film material (also known as "Sediq") is the core of wet film humidifier. It uses plant fiber as the base material, and is sintered with special resin to form a corrugated plate-shaped cross-overlapped polymer composite material. Excellent water absorption, good self-cleaning ability, non-toxic, acid and alkali resistance, mold resistance, flame retardant and provide the largest contact surface area between water and air.

4. How to use the humidifier
In the process of using a humidifier, various problems are often encountered, such as why the humidification effect is not ideal when the humidifier is always on? Where is the humidifier suitable? Do you need to close the doors and windows when using it? Questions such as these.
1. How to use the humidifier for better effect?
In order to obtain a good humidification effect, factors such as climate, room area and humidification capacity of the humidifier should be considered comprehensively when purchasing. If you live in a windy and dry area or have a large room, the amount of humidification required should be larger. When using a humidifier, you should also pay attention to the control of humidity. Too low humidity will make people's skin tight, dry mouth, and easily cause respiratory diseases such as bronchitis, flu, and rhinitis. But too high humidity also affects the water balance between the human body and the environment, making people feel stuffy. It is determined by experiments that people feel the most suitable and beneficial to health when the humidity is 40%RH～60%RH. Therefore, it is best to choose a humidifier with automatic constant humidity function. Only when the indoor humidity is lower than the standard range, the machine will start humidifying, and if it is higher than this range, the amount of fog will be reduced until the humidification is stopped. If you use a humidifier without automatic constant humidity function, it is best to put a hygrometer indoors to keep track of the air humidity. And adjust the working condition of the humidifier according to the humidity.
2. How to maintain the humidifier?
The humidifier should be installed on a stable plane with a height of 0.5 m to 1.5 m, away from heat sources, corrosion and furniture, etc., and avoid direct sunlight. Do not use it in freezing conditions, and stop it immediately in case of failure. Clean the humidifier once a week. Do not put the machine into water when cleaning. When cleaning, the water temperature shall not exceed 50°C.
3. The magical effect of the humidifier
(1) Add special perfume to let the fragrance mist linger in it, adding a bit of romance and warmth to a warm and humid home. However, the perfume should not be oily, and the concentration should not be too large, otherwise it will affect the evaporation of the mist. (2) Adding a special disinfectant solution into the water tank can effectively prevent viruses such as influenza and pneumonia from invading the human body. Wrap Chinese herbal medicines such as Radix Isatidis with cloth into small packets and put them in the water tank to prevent colds.
4. Contraindications to the use of humidifiers
(1) It is not that the larger the humidification volume, the better. It should be kept between 40% and 60% R H, and the humidification volume of the humidifier should be controlled between 3o0 and 350mL per hour. (2) Various humidifiers have different requirements for water quality. For example, pure water should be used for pure humidifiers, pure water or distilled water should be used for ultrasonic humidifiers, and ordinary water should be used for electric heating humidifiers. (3) The water in the water tank of the humidifier may be used up at any time and the machine may be damaged by idling and dry burning. Therefore, try to use products with automatic protection against water shortage.
