In Japan, they came up with a mobile “human refrigirator” for heat sufferers.

It’s already on sale. The cost of one refrigerator is approximately $10,000.

Against the background of record heat waves in Japan, an unusual device for rapid cooling of the body has been developed – a personal cooling cabin, called the Do Hiemon Box. According to the developers, in just 10 minutes it helps to significantly reduce the heat load on the body. The new product is intended primarily for employees of construction sites, factories, warehouses and other enterprises where people work for a long time at extremely high temperatures.

When the air temperature exceeds 40 degrees, the solution, which until recently might have seemed fantastic, has already become a commercial product.

The Do Hiemon Box is an individual cooling cabin with a height of just over two meters, designed for one person. The user goes inside, sits down and closes the door, after which the system directs an air flow with a temperature of about 5 degrees Celsius to the head, neck, shoulders and back, while the temperature inside the cabin itself is maintained at about 15 degrees.

According to the developer, after just five minutes, a person feels a noticeable decrease in body temperature, and staying in the cabin for about ten minutes helps effectively remove overheating and reduce the effects of heat stress.

The developer of the device was the Japanese company SDRS, specializing in cooling systems and automated equipment. The novelty is being sold by industrial equipment supplier Trusco Nakayama.

The cabin is comparable in size to a vending machine for drinks. It is equipped with wheels, which makes it easy to move and does not require special installation. In addition, the device consumes about half as much electricity as a mobile air conditioner for a similar purpose.

To prevent hypothermia, the system automatically shuts down after 20 minutes of operation.

The main users of the device should be employees of construction sites, warehouses, manufacturing plants and other workplaces where people are exposed to high temperatures for a long time.

One of the first cabins has already been handed over to the city of Maebashi, where anyone can use it for free during business hours.

The appearance of the new device coincided with one of the hottest summers in Japanese history. In recent days, temperatures above 40 degrees Celsius have been recorded in the country for the first time this year, and the number of cases of heat stroke continues to grow.

The cost of one refrigerator is about 1.5 million yen (about 10 thousand dollars). Despite the high price, the manufacturer believes that this investment may be justified for employers, as it can preserve the health and even save the lives of employees in the face of increasingly frequent extreme heat waves.

My comment.

They took an ordinary refrigerator, reduced the power of the compressor, put a chair inside, that’s all a “fantastic invention”! Poor, a stupid and deceitful “idea”. Not only construction workers suffer from heat, but any people, especially the elderly (excessive heat stress on the heart, exceeding the compensatory capabilities of a weak body, easily kills!)

So it’s just that pedestrians who have to be on the street, old and young, should become dray horses and drag this cart behind them, because no municipality can put hundreds of thousands of booths on all the streets of the city, Let alone rural areas!

In addition, when a steamed worker sits, cooling down, in such a cabin, he is blown by an EXTREMELY COLD stream of air, which is SURE to cause a cold (at best) or pneumonia, sore throat, sciatica and a dozen other diseases in a few minutes!

FOR THE YOUNG AND HEALTHY!

And for seniors, as one Japanese “scientist” recently suggested, “go straight to CASKET!” and thereby reduce the aging of the population.

( “This problem is very acute in Japan! We urgently need to get rid of the elderly!”)

THAT IS THE TRUE PURPOSE OF THIS “PHILANTHROPIC” COMPANY!
 

If we are going to make an individual cooling system, then it should be light and purely individual, namely: A garment fabric woven from capillary threads through which a small portable pump drives the coolant from a small cooling unit.

(A traditional compressor with gas expanding in capillaries or a thermoelectric Peltier effect (this is both easier and more convenient, because no special sub-zero temperatures are required))!

Heat removal occurs, for example, from soft radiators-wings on the back, thermally insulated from cooling clothing,

The capillaries themselves are mirrored from the outside, reflecting visible and infrared radiation. Powered by a small but powerful battery, on the belt of clothing. Clothing can be in the form of either regular or underwear. Of course, under the control of thermal sensors and a microcomputer.

This GENTLY COOLING system does not require much energy, does not interfere with the ventilation of the body from evaporation of sweat and gives complete freedom of movement of the body!

Possible option: The capillaries are porous and cool air is simply pumped through them, SLIGHTLY cooling the entire surface of the body.

This can really be one of the solutions to prevent overheating, rather than carts languishing from the heat, dragging behind them, like haulers, “individual cooling booths”, and at the same time you can put a toilet and a shower unit there!!

What about? After all, it’s like dragging a stall with a toilet and a shower, the same!

On wheels!
