[Technology Story | Episode 4] - The birth of the standard machine and the trial and error behind it -

To differentiate ourselves with groundwater heat pumps,
We have signed a contract with an Italian manufacturer that has a track record of exporting to over 70 countries around the world.

The company's headquarters are located near Venice.
I visited the factory many times with my employees.
While undergoing technical training, I seriously envisioned spreading the technology throughout Japan.

Heat pumps work on the same principle as air conditioners.
However, in Europe, large commercial water-cooled or air-cooled models that circulate water are the norm.

In Japan, the market is dominated by large manufacturers such as Daikin.
The market price for a commercial 16 horsepower (approximately 55 kW) model is around 2.5 million yen.
However, if mass-produced, the manufacturer's cost will be in the 300,000 to 400,000 yen range.

When you see through this "price structure,"
I was convinced that I could do it in Japan.

The Italian side also entrusted us with the role of acting as a Japanese office.

but--
Commercial use requires heavy maintenance.
A construction system is also necessary.
It falls short of revolutionary reduction rates.

That's the conclusion we reached.

The heat pump itself can be made smaller or eliminated.

This is where the development of a standard machine began.

The current standard is a two-stage design.

With groundwater, electricity bills are 1/10 of those of air conditioning.
Even without groundwater, it's 1/5.

Moreover, only a very small chiller is required.

The key is,

- Forced evaporation at low temperatures
・Direct gas-liquid heat exchange

These are the two.

It controls the rise in humidity, which was a weakness of evaporative coolers,
The capacity is doubled.

The capacity of industrial cooling towers can also be doubled.
Chiller energy costs reduced by 80%.

Some of them have been applied for international patents.

While utilizing natural energy,
Reduces electricity bills by 90% with the same capacity as an air conditioner.

Even without groundwater, it reduces emissions by 80%.

Heating capacity is doubled by using solar heat and groundwater heat.

And now――
We are developing a new heat source to replace heat pumps.

Patent with a professor who served as chairman of the International Atomic Energy Conference.
Foehn effect = utilization of condensation heat.

The basic design is complete.

However, we lack the funds and manpower to begin prototyping.

The six current standard models have been certified as energy-saving by the government.
There are also many proofs.

If you are a company with strong sales capabilities,
It will soon be in a big market.

But we're not looking for a sales company.

A company that can build a manufacturing system together.

Mass production, improvement, and development of next-generation models.

And the final goal is...

A small mass-produced model that can be used at home.

Once this is completed,
The world's energy structure will change.

The story is still in progress.

Behind this development is
There's an even more interesting story.

I'll do that little by little from next time.

We are now
We are looking for partners to build the future together.
