Humidifier classification

November 19st
Following on from this morning's article, I may have written about this before, but I'd like to explain the classification of humidifiers again.
Humidifiers sold at home appliance stores can be broadly divided into the following four types.
Evaporation type
hybrid type
Steam type
ultrasonic type
First, the easy-to-understand steam type
It simply heats water and vaporizes it.
It has strong humidifying power and does not lower the room temperature.
However, since it heats at COP1, it consumes a lot of electricity.
Another feature of this model is that its humidifying power is so strong that it can cause shoji screens to become floppy and prone to condensation and mold.
I used to see them a lot in the past, but I don't see them much these days.
ultrasonic type
A method of humidifying water by micro-vibrating it with ultrasound to break it into smaller droplets.
It uses little electricity and is quiet.
However, most of them have a small capacity and poor humidifying power.
A major drawback is that if mold and bacteria grow inside the container and are not cleaned properly, they will simply spread everywhere.
There is a term called humidifier disease, and it can be said that it mainly occurs when using this type of humidifier.
Most of the stylish humidifiers you see in general stores are of this type.
Evaporation type
Water is stored in the water bucket at the bottom and about 20 disc-shaped plastic plates or sponge-like objects made of woven thin nylon threads are rotated.
Once the wet disc is aired up, a fan is used to blow air on it.
In short, it is an extremely primitive method that simply involves vaporizing large amounts of gas by ensuring a large surface area.
The power consumption is extremely low, as it only requires a fan.
Panasonic also sells larger models, and personally this is the one I recommend the most.
hybrid type
It is basically an evaporative type, but its unique feature is that the air is heated.
Although it uses a little more energy than the most energy-efficient evaporation method, it is effective immediately.
Other special humidification methods
Daikin Air Conditioner "Ururu Sarara"
It's very famous.
This may be fine if you are just humidifying one room, but if you live in a well-insulated house and are heating the entire house with a single air conditioner, the amount of humidification is simply not enough.
Also, the moment you turn on the humidifier, the power consumption increases significantly.
There is a small note in the instruction manual, but I don't think many people read it that far.
However, it does have the advantage of not requiring the hassle of water supply and cleaning.
The basic principle is that the outdoor unit collects moisture in the outside air and releases it indoors.
Daikin Desica
The basic humidification principle is the same as Ururu Sarara.
But the capacity is completely different.
It easily covers an entire house.
However, its functions are limited to humidification and dehumidification.
No water supply is required.
Even in summer, it is possible to reduce the relative humidity to 40%, which is almost impossible with an air conditioner.
The only downside is that it costs about 150 million yen just to humidify and dehumidify, and the efficiency of humidification and dehumidification is not that good.
Since it barely sold, when it was discontinued, there was no alternative model, so it was only available for one generation.
From my experience, many doctors are very particular about humidity, and many of them have a flexible budget.
As a result, doctors tend to want to use this model.
It is believed that the "Sarapoka air conditioning" option available at Ichijo Komuten is the result of Ichijo purchasing the rights to Daikin's Desica and having it manufactured by Chofu Manufacturing.
