[Solved] ROTENSO SOLE 3.5kW Air Conditioner (Japanese Production): SCOP, SEER, A+/A++ Class Experience

Has anyone ever dealt with this company's air-conditioners?
The 3.5kW version has SCOP and SEER quite high which gives it class A + / A ++.

Chinese, the same factory as GREE, SINCLAIR

well, and I was tempted by Chinese production ...
I will probably stay with LG 3.5kw basic.

Or maybe something else is worth paying attention to?

Added after 1 [minutes]:

On their website, there is indeed information that production in Guangzhou

Certainly Quieter than LG basic and much better performance.
I have installed a few of them and they work flawlessly.

So far, I have mounted both pieces and as independent and multi-knocks, no problem. It is not entirely true that it is Chinese, because the compressors are identical to those in Daikin.
And LG is not the same air conditioners as a few years ago.
Two identical units from one delivery and the noise level between them heaven and earth.

You are thinking of something for years, a Toshiba idea or something from this shelf, unfortunately, they are not the cheapest devices.

today the company has installed a rotenso salt 3.5kW in my apartment so far cool, only one cool function is known to cool the water flowing outside it is water but where is it from? and a question about the dry function and how does it work in the sense of how it removes moisture from my house? Thank you for your help

Water, or distillate, is produced on the cooler. Moist air flows around the radiator fins, the temperature of which is below the dew point, and this causes water to condense from the air. Then the water flows into the gutter and then somewhere outside. As for the second question, the answer is the same, but the device tries not to lower the temperature in the room.

As already, let's use the terminology used.

1.) Almost fine this trough is called the drain pan, sometimes a drain pump is also used, but that's a different story, this cooler is called the condenser in the outdoor unit and the evaporator in the indoor unit.

2.) Almost fine In the era of inverters, the outdoor unit is the heart of the microprocessor-controlled system.
after reading the condenser temperature and air temperature, it selects the operating parameters of the indoor unit so that it does not cool the room, and at the same time causes the precipitation of water from the water vapor contained in the air.

But you jumped out like an elastic from your panties, think about what you wrote. Correct what you wrote about the radiator. Writing to write, well, every point counts. Sometimes you have to write so that a person can understand and not use phrases such as evaporator condenser TZR EZR

However, I can see that you don't have much information about ROTENSO air conditioners. It has never been installed in China and the basic technical solutions are borrowed from DAIKIN with his consent.
But with a choice of GREE, MIDEA, MDV, GALANZ etc, he chose ROTENSO.
Nice equipment for a decent cash.

On their website, there is information that the factories are in China and only a design office in Japan.

Question, can someone explain to me what is this heating climate that works as a heat pump ????? thank you very much

Your refrigerator is also a heat pump. It is not very clear what to translate so much of this on Google that the head is small. And if one cold does not exist, it is only heat.

In fact, "Total Chinese", not any Japanese product. Quote from their website:
"The company's headquarters and development center are located in the heart of Asia. This is where unique and innovative technological solutions are created. The production facilities and development center are located in Guangzhou, China. This is where the idea becomes a solution, a complete device that makes us proud . "

I read the thread on a different matter, but I noticed that my colleague mirek301's attention was drawn to the wrong naming of the coolers, in the end, however, what was going on was not explained. The "" cold cooler "in the house is the one in which the refrigerant evaporates and that is why it is called EVAPORATOR, while outside there is a cooler in which the gas is condensed, therefore it is called the CONDENSER.

A colleague of "p.obelix" once pointed out to me that I was thinking right, but I wrote the effects of bothering wrong, although the post was edited and the nomenclature is correct in the post. Describe the air conditioner below.

https://pl.wikipedia.org/wiki/Klimatyzator


- the evaporator decompresses and evaporates the liquid refrigerant, the expanding refrigerant cools the evaporator collecting heat from the environment.

- the condenser is designed to cool the refrigerant in order to condense it again, hence its name.

Yes, enough nonsense has fallen higher.

Climate is basically a simple system,
The compressor in the outdoor unit compresses the refrigerant up to the pressure in which the refrigerant changes into a liquid state, the compression process releases heat which is transferred to the environment by the condenser ("cooler") outside.
The cooled liquid refrigerant is transported by a pipeline to the indoor unit where, thanks to the expansion valve, it changes the aggregate state in the evaporator ("cooler") back to gaseous state, and in the expansion process, cold is released in the room. Later, the gaseous refrigerant returns to the compressor and the cycle repeats itself.

If you set the heating mode in the climate, the internal valve changes the direction of the refrigerant flow, the internal cooler takes the role of a condenser and transfers the heat to the room, and the external evaporator and transfers the cold to the outside ?

Rotenso is a good Chinese, I can confidently recommend.

In the age of globalization, everything is more or less Chinese. Many world-renowned companies have their companies in China because it is cheap there and everything is immediately available. Unfortunately, this also applies to air conditioners.
