Yes, this is a soft water, perfect for the plants, since it's created the same way as the snow develops from the air in the clouds, then melted at Spring 🙂
Hello, I have a 12kw T Cap in a climate zone with a minimum temperature of -2°C. During the night it defrosts once an hour, recording between 10 and 12 defrosts. In your case, with -7°C, how many defrosts do you think it does?
Hi, the frequency of the defrost cycles depends strongly on the temperature and the humidity. In case of a foggy weather the frequency of the defrost cycles rises also at 1-2 degrees Celsius too, since the external unit works at around 0 or -1/-2 degrees in order to get heat from the air, so the humidity will begin to freeze on the unit. Therefore, it doesn't matter the warmer climate, at -1 or -2 degrees in foggy weather, the unit will defrost many times. I noticed that my device defrosted every 35-40 minutes at these weather independently from the -2 or -5 degrees Celsius. It's true, that this weather is the worst condition for air source heat pumps, since lots of energy is used to defrost itself which needs heat from the pre-accumulated source, from the buffer tank. In case of a dry weather with no clouds and very clean, dry air, it can be -5, -10 degrees, it hardly defrosts, since there is not much humidity which freezes on the heat exchanger. We had a winter with -17 degrees Celsius, it worked very well and effectively without any problem since there was no humidity at those temperatures and defrosted quite rarely. I hope this gives you the answer ;-)
Those "hiss" noises are caused by the four-way-valve when it changes from heating to cooling at the beginning of the defrost cycle, then back from cooling to heating at the end of the defrost cycle, the movement of the valve causes the sudden pressure drop of the refrigerant, this makes the strange noise. This is the reason why I wanted to take a full defrost cycle in order to hear those hisses as well..
Hi Christian, I don't find the unit noisy, just recorded it with a good quality cam :-) I also found it noisy from the cam recording, however it's not so noisy in reality. I suggest to visit someone who has this kind of unit and check its noise level. Just uploaded the videos to have an impression about the noises during the full defrost cycle, since I have not found videos before about the full cycle recorded. Since the unit is beside a wall and not in the edge, the noise level is less, there are also plants by the fence which can reduce the noise towards the neighbors, the next house is at least 10 metres far from us. The unit is standing beside the cellar, the living room is 1,1 m above the ground level, so we can not hear it from inside. A little noise can be heard at high frequency at night, but since it's continuously working, the maximum compressor frequency is quite rare. I hope I could provide you with useful inforation, thanks for your questions

@@univerzum9830 Szia! Köszi! 🙂2017 januárban, amikor napokon keresztül nagy mínuszok voltak, az olvadékvíz belefagyott a csőbe és egy több méteres, 15 cm vastag jégfolyam alakult ki.

It reverses (to cooling mode) full power. But since both inside and outside fans are off during defrost you are not going to notice a change in temp inside.
I could check a few defrost cycles in the last weeks, the compressor frequency is 30 Hz during the defrost cycle. The water pump is strange, there were defrosts when the pump speed (4) did not change, but I experienced two times that the water pump turned to maximum speed for a few seconds at the end of the defrost cycle. I don't know why, maybe if the weather is colder it may need more heat from inside to perform the defrosting. Since there is heat transferred from inside, the outlet water temperature decreases 4-6 degrees during defrost, but as soon as the defrost is over, it sets back to the previous temperature within a minute. We have 300 liter buffer tank connected to the indoor unit
for those who are not understanding how defrost cycle work and why , here is the awnser from understanding remember this: in heat mode heat is inside the indoor unit and cold in outdoor unit in cooling mode cold in indoor unit and heat in outdoor unit while in heat mode the cold on the pipes at the outdoor unit freezes so the air conditioner put it self in cooling mode so cold in indoor unit but the fan stops in indoor unit so you wont get cold while outside the outdoor unit there is heat to melt the ice. why : because the fan will not suck air while ice is collected so the heat efficiency will drop sorry if my English is bad thanks.
Are you capturing water for the plants? 👍 😃 Really cool!

That thing makes some *freaky* noises during the defrost cycle.

Like all. My ivt ax 09 is noisy too. But is faster. ruclips.net/video/TyLq0g3uezA/видео.html
@@zoltanhorvath294 good to know, my split A/C from Haier on the inside unit makes this noise too but it;s just normal
Hello,
Do you think, that the unit is noisy? especially at night?

Wow
Hova folyik a kültéri egységből a kondenzvíz? Összegyűjtöd valamiben?
kútba vezetem bele, mivel ez felolvasztott esővíz, így valamennyire visszapótolja a nyáron leapadt víz mennyiséget

Hi, can you tell what is compressor frequency during defrost? Also does it pump heat from insideofhouse to do defrost?
It reverses (to cooling mode) full power. But since both inside and outside fans are off during defrost you are not going to notice a change in temp inside.
I'll check the frequency during the next defrost cycle
I could check a few defrost cycles in the last weeks, the compressor frequency is 30 Hz during the defrost cycle. The water pump is strange, there were defrosts when the pump speed (4) did not change, but I experienced two times that the water pump turned to maximum speed for a few seconds at the end of the defrost cycle.

J-series Aquarea-t várom R32-vel.
So the defrost cycle takes about 4 Minutes, what was the outside temp?
It was -7 degrees Celsius
for those who are not understanding how defrost cycle work and why , here is the awnser from understanding
remember this:
in heat mode heat is inside the indoor unit and cold in outdoor unit
in cooling mode cold in indoor unit and heat in outdoor unit
while in heat mode the cold on the pipes at the outdoor unit freezes
so the air conditioner put it self in cooling mode
so cold in indoor unit but the fan stops in indoor unit so you wont get cold while outside the outdoor unit there is heat to melt the ice.
why : because the fan will not suck air while ice is collected so the heat efficiency will drop
sorry if my English is bad
thanks.
Very long time for defrost and very noisy :-(
It just sounds noisy since the camera's microphone was too sensitive 🙂 From 3 metres you can hardly hear anything
Znaffffcy i fanatycy teoretyki ti-kapa nie napiszą że strasznie głośna???? 🧟🤥🤥🤥🤥🤫🤫🤫🤫
sorry, only English :-)
..or Hungarian :-)
