Bro, both points are valid. I also mentioned that part as well earlier. Not just for Seramban, there's also Taiping and some part of Ipoh and Kuala Kubu Baru too as well as many other parts of country like it. It depends on where the location is. Some need it, some don't.

Which model? I saw in brochure that the deluxe inverter is said to be rated at 431W only. The same range for 1.5hp about 705W. Up from that is the premium one with wifi which runs at 405W and 530W for 1.0/1.5hp. From what I was told, it needs 4 core wires - at least that's for the inverters. Samsung support is non-friendly. Only a community of installers with tribal knowledge (by experience and prior training) knows this first hand according to my installer.

Their inverter price cheaper than most except Sharp. However, from their installation manual they need more breathing space than most other Jap made ones. That justifies the comments that most made that the Jap ones lasts longer.

That's because either: installation issue near fairing or pipe defect or pipe quality issue. Either way, both Daikin and MHI can pump 10-20m max vertically depending on HP. Take an educated guess which will fail first. Normally those cheap China copper. I had a fair share of that myself until SG friend educated me on AC piping. Hence I go with Inaba Denko or Smartco Paircoil. Ironically the older AC pipes from early 1990s are much tougher and durable by today's standards that are quite durable even for R410a inverters but don't take my word for it.

Got, the spread of air circulation emphasis is different. I don't know which one is widest or narrowest side but consider this:
On narrowest wall facing widest side , LR circulation not much as UD.
On widest wall facing narrow, LR emphasis depends on cooling zone. Long rectangular table may need more LR or fixed focus L and R. Circular table not as bad.

Then again, the other factor that will influence placement is the length of the run for embedded piping and drainage which implies the amount of hacking needed.

Left Right Up Down

One thing most of us don't realize the danger of prolonged cooling at very low temperature is the dehumidification rate. 2HP some can be as much as 1.5 to 2liter per hour. Tell tale sign if don't drink enough water is very easily get sore throat or throat irritation.

Agree with the first part. That's how I got asthma. And that's how I learnt from some doctors about aircond and dehydration. More pronounced if it's pregnant woman in first trimester. Serious morning sickness (aka pregnancy induced dehydration).

Either they have more advanced and configurable circulation features or more powerful cooling rate. The key is to spot cool where the users are or to surround the area around them to let them perceive that it's cooler. The 1hp already has 3D swing of 8 possible configurations.

Ya, the phlegm helps slow down rate of dehydration but it narrows the passageway hence inducing breathing difficulties. But then that was long long ago. Now ok dy. After doctor showed how it's related, just realized that all I needed is just enough not to sweat or feel discomfort.

MHI won some awards for their innovative circulation feature. One thing they did was to study that cooling is mostly to satisfy the area where occupants are and then spread out around it. The other one is PCB sealing against humidity for greater reliability.

I think what you meant is for ME, because of the odd pipe size even for 2.0hp, might as well go for 2.5hp?

Ah ok. If change pipe can. Retrofit over existing a bit hard.

If triangle is inverter, suggest go for ARnnHVSDB. It has better energy saving rate. Legend and 88 electronics can get it cheaper than elsewhere if you're in PJ. But warn your installer that he needs to prepare 4 core wires from DB to compressor instead of the usual 3.

LOL, I have a confession, you're never alone. I also guinea pig I already installed 1.0 and 1.5HP inverters in bedrooms. Very quiet at 20dB. 27-28deg C with 1 speed fan and VirusDoctor turned on. Auto LR used in 1.0HP and UD used in 1.5HP. The wattage can track by 2nd Function button and then Watt Usage. After turn off in morning, always auto clean to prevent mould build up.

This one only because of room configuration. The 1hp is sited on widest wall so need to blow LR. The 1.5 sited on narrowest wall and only need to throw up down.

Well, my requirement is minimum cooling only. Lowest is 27 on AUTO fan with 1 speed ceiling fan. Higher speed ceiling fan if warmer but still same temp. Reason being the high dampness. At that temp it's lowered to something like 65-70% relative humidity (RH).

See the attached.

Harvey Norman Paradigm Mall. Let me see if I can retake but it's at home. Not sure how they rate the wattage. It could be partial load like how SG does it.

On paper, inverter wifi more saving. For the 1.5hp premium inverter without and with wifi is 705.4 vs 584.4 W Whereas for 1.0hp it's 463W vs 413.8W

But the one with wifi has heavier compressors at 30kg vs 26.4kg without it.

probably undersized. I calculated ngam gnam only at 13427 BTU@hlf=60 but probably have not taken into account lighting fixtures and occupant. 2hp should be better. Also if compressor is located below blower, Pana has height vertical height limit of 5m.
