FrostWash by Hitachi, the air conditioner without maintenance

Hitachi Cooling & Heating laboratories have succeeded in create an innovative technology that maintains the air conditioner clean, purifying the home air at the same time.
Premium FrostWash, the model equipped with this new technology, features the heat pump and is in A +++ energy class, ensuring a reduction of consumptions and a low environmental impact.
The most important innovation of this product is its ability in maintaining its parts and components very clean so that the emitted air is also very pure.
The FrostWash function, in fact, captures, freezes, washes and eliminates 91% of bacteria and 87% of mold present on the surface of the exchanger, to guarantee perfect hygiene of the air conditioner and a healthy environment. The function is automatically programmed but can also be activated by remote control. In this way, the air conditioning is always clean, also thanks to the internal components made of stainless steel, a material that reduces the percentage of bacteria by over 99% and dust by 62%. Moreover, the self-cleaning robot activates itself periodically, not requiring the opening of the air conditioner to clean the filters, so that classic maintenance is not necessary.
Premium FrostWash, that also received the Good Design Award by the Japan Institute of Design Promotion, is available in two versions: matt white and silver.

Dyson Airblade 9kj hand dryer .

Dyson has recently launched a new technology designed for business spaces: the Dyson Airblade 9kj hand dryer .

Dyson Airblade 9kj is the fastest and most energy-efficient hand dryer with a HEPA filter . Powered by the Dyson V4 digital motor, which performs up to 75,000 rpm, it dries hands in just 10 seconds . This is also possible thanks to its unique and innovative design, Curved BladeTM Design: the two curves have been designed to ensure that the air follows the contours of the hands, removing the water faster and ensuring optimal drying. Thanks to its HEPA filter, it also allows hygienic drying, as it captures 99.95% of the particles from the bath air, including bacteria and viruses.

Dyson Airblade 9kj is a sustainable alternative to traditional hand-drying methods, such as paper towels – which are often not recyclable – and hot-air towels. As measured by the Carbon Trust, a non-profit association that aims to help companies reduce their environmental impact, Dyson Airblade 9kj produces up to 85% less CO2 emissions than paper towels (2.5 g vs. 17 , 1g of CO2).

Rain is a beautiful humidifier from Japan

Rain is a beautiful humidifier with an innovative tankless structure. Water can be supplied simply by pouring water from above. Advanced operation with beautiful display and control ring. The dry air taken in by Rain first decomposes bacteria contained in the air taken in by the enzyme filter. Removes dust and other germs and humidifies and sends out clean air. Provide a clean and appropriate humidity for a healthy dry season.

Every season has its electrical helpers. In the summer it is the fans , in winter the humidifiers. Although the heat in July and August is noticeable faster than the dry indoor air in December and January, but health problems can be both.

First of all, let’s take a look at how it comes to dry air during the heating season. You have to know that the outside air is always dry in winter , because cold air can hardly absorb water vapor. So when we ventilate our houses and apartments in the winter, cold air flows from outside to inside – and is heated there. The warmer the air gets, the more water vapor it can absorb (absolutely). However, since heating does not increase the absolute amount of water molecules in the room air , the relative humidity decreases . In part to less than 30 percent.

For this reason, frequent airing in winter does not help at all against dry air. One achieves the opposite. Remedy in the cold season only house plants and humidifiers.

The question remains, why it is ever so important to moisten the air in winter. The simple explanation: We humans perceive a humidity of around 50 percent as “pleasant” . If it exceeds 60 percent, it can lead to the spread of mold. If it drops below 40 percent, our mucous membranes dry up in the throat, nose and bronchi. As a result, the cilia can no longer perform their cleaning function and bacteria and viruses have easy game. We become more susceptible to infections, headaches, concentration problems and skin irritation. Especially for allergy sufferers and asthmatics, dry air quickly becomes a problem.

In our case, the thing looks a bit different, because we have a ventilation system. This means that we no longer have to ventilate by hand, but a central ventilation system ensures the required air exchange 24 hours a day. This is extremely comfortable from March to October. From November to February, however, we constantly get the dry air into the house via the ventilation system. With indoor plants alone that can hardly compensate – unless you want to build a botanical garden in the living room.

So all that remains is the use of a humidifier. The range of brands and models available is huge – but the Balmuda Rain stands out from the crowd.

That starts with the design: Most humidifiers are not visually appealing. Actually, they do not want to put themselves in the living room, but in the end they have no other choice. The Balmuda Rain is different. The open design is reminiscent of a vase and is modeled on earlier Asian water vessels. And just as you fill the Rain also: like a vase, from above with a watering can. The capacity of 4.2 liters is generous and ensures that you do not have to constantly refill.

The next highlight is the way it works: While other manufacturers realize humidification with ultrasound (vibrations) or evaporation (heat), Balmuda uses an evaporation process for the Rain :

IT USES THE LAW OF NATURE, ACCORDING TO WHICH THE WATER LEVEL IN A CUP DROPS BY ITSELF DURING THE DRY SEASON; HIS HUMIDIFYING POWER HE DRAWS FROM THE POWER OF THE WIND. NO GERMS ARE RELEASED AND THE HUMIDITY DOES NOT RISE EXCESSIVELY. THE PROCESS IS ALSO CHARACTERIZED BY LOW ENERGY CONSUMPTION.

In fact, the power consumption due to evaporation is significantly lower than in other processes: While ultrasonic humidifiers have a power consumption of up to 380 watts, the Rain has a maximum of 23 watts . So you can let the Rain run calmly over a longer period, without having to fear a high electricity bill.

Balmuda Rain: OLED display and high hygiene standards
Balmuda has placed great emphasis on hygiene in the Rain . In my opinion, this is very important, because a healthy indoor climate requires not only the right humidity, but also clean air. The Japanese company has therefore chosen the following structure for the Rain:

Balmuda Rain – construction

Another highlight for me is the OLED display on the top, over which you pour the water, so to speak. It displays all the important information (desired humidity, actual humidity, level, etc.) and visually supports the operation of the humidifier via the control ring (turn, click).

This is how the Balmuda Rain beats in practice
So much for the theory. But how does the Balmuda Rain affect everyday life? In principle, there are three modes to choose from:

Automatic mode: In automatic mode, Rain automatically maintains a set humidity level.
Manual mode: In manual mode, you can manually select five air volume levels.
24 Hour Timer: Activation of Rain can be programmed in units of one hour. So you can stop the operation when nobody is home, and restart shortly before your return.
