No, not yet. I got my air cond guy to come and have a look at the room. He suggested adding an awning to cover the walls that are exposed to direct sunlight.

Might work to a certain extent. Awning only meant to shade or prevent glare from the sun's position during the day. It delays the direct exposure until a certain angle later in the afternoon. A louvre cladding over the exposed areas will prevent that at all angles. Maybe a combination of both. The same roof cladding link I gave can also be applied on the walls using furring strips such that it becomes a stucco with an air gap behind it. Then the awning prevents water intrusion from the top of the cladding.

Between a 1.5hp Daikin and Panasonic, which one better?

All air cond dehumidifies. It's how the air becomes dryer....through dehumidification. Are you looking for a humidifier in this instance? To have the room air more moist than dry? Is she asthmatic?

For those using 1.5HP non-inverter now, should I choose 1.75/2HP inverter when upgrade new air cond?

From my experience, for the same HP, non-inverter should be colder than inverter.

Calculate the cooling load first. That will determine the HP required. If cooling load within the 1.5HP (12500-14500BTU/hr), use back 1.5HP. You can use 1HP if it's lower. Any higher, check the piping spec and see which higher HP model matches. But if the piping are meant for non inverter esp older refrigerant (R22), then change the piping to withstand higher pressure from R410a/R32 gas. Don't reuse esp if the older AC uses R22 gas. Safer option is to change the piping.

Ok, based on formula it's 15k+. So I guess either 1.75/2hp. Changing to bigger pipes cost extra if purchase new aircond? The last time I bought aircond it comes with free piping but that was looking time ago.

Looks like only Panasonic has anything with 1.75hp

Yours landed or condo? Depends whether the current pipes are spec even for 1.75HP. What's the model of the older 1.5HP? If unsure, look for the model information either at the side or bottom of the blower unit. Sometime it will mention refrigerant whether R22 or R410a. If it's R22, better to change to thicker piping (0.81mm).

Inverter Aircond usually has more BTU than non-inverter. Does current Aircond struggle to cool the room and need to use 16degree all the time? If not, I don't think you should increase the HP.

Mine landed and using Mit HI premium non inverter aircond for the last 5 years at least. For sure I think it's R22. When we buy new R410/32 aircond, did it come with new ticket piping for free?

Landed easier to repipe so long as its mounted over the front where the sliding door, large windows should be compared to say in the living room wall over the TV cabinet. Recommend AC drain use a bigger pipe diameter like 19mm (3/4").

AC Piping separate unless the shop very generous. But if you're keen to use inverter, get good piping like Inaba Denko Paircoil. May cost a bit higher but in the end, your AC operates efficiently.

BTW, did you include dining area if it's adjoined to your living room either contiguous or split level? If not, include it in your calculation or at least upsize cooling load by 20-30%.

How did the MHI non inverter ion perform? Any insights to share on its usage?

I have this MHI in my master room. Do I have to buy the piping before installation or the installer have the choices available. If I need to buy my own pulling, where can I buy the recommended brands?

So far this MHI non inverter is probably the best I use. I've used Daikin, Mitsubishi Electric before. Cooling power is slightly better than Mitsubishi Electric feeling wise but slightly noisier blower.

Ok, back track. So this is for master bed room and landed dwelling. Is the roof insulated? Otherwise tweak the heat load factor and recalculate cooling load if you haven't taken it into account.

Piping needs to be specified with your installer so that he can get it for you. If your in KL, just google the brand and the sellers are online.

I use MHI ion inverter with 3D air cool feature. They are quite good.

Roof not insulated. Regardless, I will need at minimum 1.75hp.

Will check out MHI inverter models as well

Hey guys, looking at several 1hp Inverter type air cond for a small room

My priority is lower power consumption and based on my research, below is what I've shortlisted.

Without Ionizer
Daikin FTK10Q
Panasonic CS-PS9TKH

With Ionizer
York YWM5J10AAS-W
Midea MSMB-09CRDN1
Panasonic CS-S10TKH

In terms of reliability, which seems to have the upper hand?
In terms of ionizer performance, which is better?
Does the Daikin, Midea and York models have indirect airflow?
Is the media Smart Kit worth the price adder of RM97?

Thanks in advance! smile.gif

I'm a happy user of Panasonic CS-S10TKH, love the Auto-X function which cool really fast and change to indirect blow after coolness is reached. I just use it at 28ยบ every night and it's cool enough for comfortable sleep under light quilt.

For extended hours use of about 12 hours daily (shop usage) , is inverter recommended? I am considering between inverter and non inverter units, total difference is about rm 2k for Daikin 2hp x 1, 1hp x 2. Thanks
