Interesting unit, I only encountered one of these units while doing maintenance. I suppose the next best thing is to buy all the spare parts from the manufacturer, and assemble one yourself…..!
Hi Craig. How can you deal with the motion sensor if you want to keep running the AC 24/7 and nobody’s in the room? Should i leave the cat there? Hehe.
You have the choice to have the sensor active or not and I believe there two setting that can be set together or individually. Movement sensor so it sensors some one in the room and then comfort where it detects where you are n the room and blows the air in a different direction from where you are.
I hope that with its release, however, it will prove that the many reliability problems of the previous model have been solved. In my opinion, normal problems that could not be easily identified due to limited production, but unjustifiable since it is of Japanese manufacture and not just design. Of course, this is a complicated machine, the failure of which requires not only knowledge and experience, but also the respectful observance of the manufacturer's instructions. Moreover, all this in a very expensive machine, so let everyone judge, based on the reliability of the previous model, what to expect from the new one. @@FullyAirconditioned
Hi! Thanks for the extensive review. Stil after reading many reviews I have doubts about the following: Does the unit also do well in moisturising a room/ increasing humidity when it at the same time cools the room? I have the feeling from reviews that it only does well in moisturising when it heats a room. I am very curious what your experiences are with that..
Hi Frans, It dose add moisture to a space when cooling, but the cooling process also removes moisture from the air. When you cool the air below the dew point the moisture in the air turns to water and runs out the drain. I think if it was compared to a standard air conditioning unit, cooling the same room with out humidifier function, the air with in that room would have a much lower humidity. But the fact that you are cooling (and removing moisture) at the same time as you are try to increase the humidity, the effect will be less than in heating mode. But it will be better than a system without humidification function. It will also depend on the humidity level your trying to achieve, this system is more designed for human comfort. Thanks
@@FullyAirconditioned Thanks for the quick reply! That sounds reasonable indeed. I wonder why its phased out as you say. Here in the Netherlands, it's still available. Do you also have experience with the sound of the unit when in cooling & humidification mode? Its for my bedroom
@@franswillemvankonijnenburg6167 it makes about the same sound, the humidifier function dose add some extra noise, if the pipe length is not set correctly the noise is higher. I believe sales were not high enough, there is a new model out in Japan.
Very interesting! I've had this unit for a few years and always wondered how the fresh air came in. I was wondering if you could clarify something for me - As far as I know, it only brings in fresh air but doesn't exhaust it out, so stale air only escapes through door cracks etc from positive pressure, is that right?
Yep that’s correct, it dose have the streamer function that kills bacteria and viruses. Most homes leak quite a bit of air, unless it’s a passive home that has been sealed and warped to stop any leakage of air.
@@FullyAirconditioned That's good to know, I was wondering if I should set up a little extractor fan but that shouldn't be needed then. It's a great heat pump, I'm surprised they discontinued it. It was the only one I could find that brings in fresh air.
Germany here - I was researching a lot and only ceiling-cassette units have air-connections but nothing like this Daikin unit. It‘s still sold in Germany, only HUGE downside for me is NO MULTI Split - only one indoor unit per outdoor unit - looking around UA-cam there was a system called „URURU MULTI“ 10years ago - but there‘s nothing on the website anymore - bummer
US7 cannot make “any” combinations of those, for example it cannot make heating and dehumidifying at the same time. Yes, nobody uses heat+dehumidifying at the same time but just wanted to clarify it :) Another thing is that it makes huge noise if the fresh air hose is in use, either for humidifying and/or fresh air; but it’s super silent when there is no fresh air and/or humidification. So, it’s absolutely no-go if you want to sleep close to the indoor unit when it’s providing fresh air..
The indoor unit has two coils, in the 1st coil the gas is condensed from a superheated vapour to a sub cooled liquid, passing its heat energy to the air passing over the coil. So in the 1st coil heat is added to the air. This liquid then pass through a electronic expansion before entering the 2nd coil in the indoor unit. The metering device dropping its pressure and temperature of the gas. The liquid gas starts turning into a vapour absorbing heat. So in the 2nd coil of the indoor unit, it remove heat from the air. As the coil cools the air being drawn in, it cooling it below its dew point. The moisture in the air turns into water dehumidifying the air. The refrigerant gas has absorbed the energy held in the air and reduced its temperature. Some of that energy has turned the moisture into waster or been transformed from sensible into latent heat. The water run out the drain hose and this energy is lost to outside. The air gets reheated by the 1st coil, more heat is added than removed dew to Enregy being lost to the water. The electrical heat energy from the compressor motor is also transferred to the refrigerant gas. So now there is extra heat from the compressor electric motor and the extra heat added to the converging the moisture from vapour to water. You may have noticed that an air conditioned will produce more heat then it removes or has a higher heat out put than cooling out put. And there for all air conditioned produce more heat than they remove. So the US7 can heat and dehumidifier at the same time, yes it can dew to the two coils in the indoor unit. But the amount of heat is not huge compared to the system just running on heating, but it is adding more heat than it’s removing. With the noise from running it on humidifier has the system been set up correctly, in the set up it asks for the pipe length of the humidifier hose, if this is not set or set at the wrong length the fan in the outdoor humidifying unit will run at a higher speed to overcome the static pressure of the steam hose making more noise. But yes there is some more noise when it’s in humidification mode. You may even try setting the hose length to the shortest setting to reduce noise. Thanks for your comment
Hello! I've had this air conditioner for 3 years. One year ago a problem appeared. When I use the fresh air function the air that comes in smells bad as if there is mold in the air tube. What can I do?
I'm really grateful for your effort and knowledge here. thank you . I'm trying to find the best aircon I can for dust mites and allergies and this one was specifically mentioned I think by the asthma foundation. Do you have any other recommendations? Ive got cora 2.5kw in the kids rooms and thinking of upgrading.
The new Daikin Alira X has the same streamer technology as the us7, but doesn’t have the humidification function or roll filter. The better option would be a standalone air purifier. Daikin have 4 new models out and they are very good. We have the older one in our office up stairs and it has made a world of difference to the air quality in this space, odours dust and allergies. To give you an idea of how well it works, we had one our builders come into the office, smelling very badly of body odour with in a minute the Daikin air purifier detected air pollutants and set it self into high mode to address the current indoor air quality. With in 10 min the air quality was fine with no odours and the air purifier has slow done to its minimum setting, very impressed.
Thanks for the video. Very helpful. Do you know if this system has a slot for wifi adapter? Some system has a slot where you can hide the adapter inside. Does this one have that slot? Thanks
@Maxim Zhekov Thanks. I already bought that adapter. My question is if this adapter sits inside the unit itself. Is there a slot for it to sit inside? The installer installed it outside my unit. I watched youtube video. It seemed it could be inside. So not really sure. Much nicer to be inside rather than outside.
My question for anyone with this urura sarara is: can it de-humidify without cooling? I want to use it as well in winter, to take out the moisture that is causing mold. Also: here in Europe it's currently readily available to buy, so maybe there's a new model out on the market?
It has two coils in the indoor unit one with a tx valve, the 1st coil will cool the air removing moisture and the 2nd coil will reheat the air, so yes it can dehumidify with out cooling.
@@FullyAirconditioned Thanks for the quick answer! Have you tested it yourself though? I read this on their website: "Daikin’s Dry Mode basically sucks the humidity out of the air to create a more comfortable living space. It does this by taking in the humid air, drying it in the evaporator, and releasing it back into your home in the form of dry air. In other words, the air-con will NOT blow out A LOT of cool air in this mode; it will merely dry the air and maintain a certain level of comfort as needed." > i fear this means it will still blow out colder air than the intake temperature, don't you think?
@@gekalskip The system achieves this as there are two coils of similar size so similar capacity. If the system is off loading its capacity the compressor is running at the net output may actually be heating the air as all air conditioners have higher heating capacity output than cooling. But the fact the there are two electronic expansion valves in the indoor unit, the level of refrigerant control into each coil should ensure minimal temperature change when in dehumidification function. A normal Daikin’s system has dehumidification functions, but it doesn’t reheat the air like this one, so with a normal system yes it will also cool the air as part of removing moisture, but not the us7.
@@FullyAirconditioned Thanks a lot for your detailed response! I am gonna go look up the machine in a store and learn some more about it, but you've gotten me hopeful!
Does this system require any additional pipe work than a standard Daikin Multi split system, because I already have the standard preparation work done on a new build property.. is it likely the new model in Japan will launch in Europe?
Hi Richard, Same refrigerant pipe 1/4 x 3/8, same electrical4 core plus earth. But there is a steam hose that runs from the indoor to the outdoor unit, insulated and is about 32mm in size. Don’t know if the if it will be coming out in Europe.
Hi nice review! Inwas wondering which wifi module is best for this, and supports power consumption as well for this unit? And can this wifi module be build into the unit? I just checked one youtube which did an external mount of the wifi?
So you have a US7 and you want wifi, you will need a wifi BRP072C42 I believe (need to double check this with Daikin) and it’s external mounted. You could put in the wall cavity or mount in behind the indoor unit if the pipe work is running straight out the back of the unit. But you will need to take the cover off to access it.
Everything will get dirty given time, microscopic bits of dirt that by pass the filter then coil but get hit and stick to the fan, that’s what block up the fan. Because this has a fine mesh filter that’s constantly being cleaned I would think it less likely.
one of the best airconditioners every made for sure! i think GREE Soyal A+++ split unit is also very good! ... different brand but it have almost the same specs
I don’t think the Gree unit come any where close to the Daikin us7, the us7 can humidifier, dehumidifier, heat, cool and all of the above at any one time. It also has very high rate of air filtration. The Gree unit can heat and cool so not in the same class sorry.
Hi Lee, Sorry don't have any more US7's, Daikin are very good with parts and I have only encountered problem is getting parts once units have passed the 15-20 year mark. You may be best to call your local Daikin dealer's and maybe they have a demo unit from there showroom or something. Kind Regards Craig hewitt
