To yamashita,

The dual cooling outlets will have little effect on the energy consumption. (IMO)

By the way, i think Sky Series is already launched in SG.
Thanks! I didnt find this model on Panasonic Singapore website, I assumed it has not been launched yet.

Just messaged my installer, waiting for her to come back with the details.

Correction to my earlier post, just watched the product video for sky series. There is only 1 cooling outlet.

Thanks for the detailed explanation... So if I take it from a newbie point of view I don't really need a 18k fcu for my living room If most of the time I only on 2 fcu right? 12k should be ok and additional 3 9k each...?
Hi, did a back search but cannot find you mentioning the brand and model of the system 4 that you intend to buy. This is because, different models have different configuration constrains. It is good if you can provide them.

Hi, personally, I cannot agree with the advertisement concept of cooling the ceiling in order to cool the room effectively. I feel that the basic objective for installing an air conditioner is forgotten, which in my opinion should be to provide a comfortable environment to the occupants and not to cool the room.

Depending on the climate in a country, the FCU is located at a height that effectively provides comfort to the occupants. In many citing and is also my opinion that the FCU should be location at a height of 8 ft plus or minus, from the floor. Unnecessary cooling can result in higher energy usage.

Cool air is heavier than warm air and therefore, cool air will sink towards the floor while warm air will raise towards the ceiling. It is not advantages to mixed them and therefore these 2 sections of air is left alone so that the cool air section keep the occupants comfortable while the warm air section stays at the top away from the occupants and use no energy. The layer of air in between the cool and warm air is the layer that the FCU draws into it to cool. So the location of the FCU determines this layer and ultimately the comfort of the occupants.

There are also other considerations in regards to the placement of the FCU. Would anyone wish to share their though?

Above are my opinion and hope that they are useful.

IMPO - I prefer environmental air cooling than radiant cooling.

Hello.

I am thinking of getting aircon for my 5rm flat and would need some help here.
Currently only 2 of us and aircon will only be used in MBR during hot weather or haze. Usually we sleep with just fan and windows open.

Wonder if I need inverter model or non inverter model will be good enough?

Secondly, i was wondering if it is possible to just install a system 1 to my MBR and in the future when family size increases we just add another set of aircon for the 2 common bedrooms?

I understand the Daikin Smile series allow expansion by just adding FCU but wondering if there will be complication when it comes to expansion?

Or maybe install a system 1 and in the future add another outdoor unit for 2 common rooms?

Appreciate your advices. Thanks!

Hi dachee bro, yes you are right have not really mentioned any models outright , currently looking at the proven starmex old models system 4 (but can't decide the BTU needed). Another option is Panasonic which is not really recommended here. Any advise that can sway me away to a particular model and BTU? ( always will be living room and MBR on most of the days)

Hi,

Did some quick checks on Radiant cooling and there are issues and debates on its effectiveness as well as problems.

In general, radiant cooling is done by cooling a surface so that that surface is about to adsorb the radiant heat from other bodies or other objects.

As we know from our primary school science, heat is transferred by convection, conduction and radiation. Both convection and conduction would need a medium but not radiation. For example, the heat from the sun heats up the earth by radiation by going through the outer space which has no medium.

However, radiant cooling may have problem in places that are humid as radiation does little to the humidity in the air. For example the heat from the sun is unable to heat up the cloud in the sky. So a body can feel cool through heat transfer by radiation but not the air.

However, within an environment, heat is transferred best in a complex and "auto-adjusted" way, with a combination of conduction, convection and radiation. Whichever method that is most efficient will dominate the process.

In short, radiant cooling would be more suitable for countries that has low humidity environment. Another consideration is the blocking of radiant heat transfer by objects. For example, standing outside under the sun, you will feel hotter than in a shade. The is because radiation can be block, so if you are sitting with your legs under the table, your leg may feel warmer as radiant heat from your legs is not transferred to the cooler surface, which for this air conditioner is the ceiling.

Above are my opinion and hope that they are useful.

To carlos83,

Currently most of the models available are invertor model.

Daikin Smile Series is a system 4 outdoor, you can just install as a system 1 and add additional blower units in the future (provided the model is still available, usually a model production lifespan is 5-7 years)

The problem is how does a customer know whether an installer is a reliable one? In my opinion, a customer will only know that an installer is reliable only when he can assess the installer. The customer need not be trained but by ensuring that the following are carried out by the installer, he is assured that the installation is reliable.

1. Ensure that the system is evacuated for at least 15 mins with a suction pump. Some installer will do purging instead of evacuation. This is not acceptable.

2. After the 15 mins, the installer will shut the manifold gauge, than turned off the pump. He should than wait for a few minutes to see if the suction pressure increases. This is to check for any leakage in the piping. You can record the gauge reading by taking a photo, and comparing it later to see that the pressure does not increase. If there is any increase in pressure, it would mean that there is a leak in the piping. The installer would then have to find out where is leaking, repair it and redo the evacuation before he continues to release the gas and charging the system.

3. Look for any opened insulation. All piping should be fully concealed within the insulation. You should not be able to see the copper pipes at all.

4. Look for insulation that are meeting end to end and check that they are glued together and not just touching each other.

5. Check to see that each copper pipe is insulated separately. There should not be 2 pipes within one insulation, except those pipes that come from the manufacturer and within the FCU.

6. Check that any gaps between the holes in the walls and insulation pipes / wires are completely sealed up even when this holes are within the conduit.

7. Ask the installer to pour some water into the water collection tray in the FCU to see that all water flow out freely into the drain pipe.

8. Make sure that the installer insulate the drain pipe too.

9. Check that all your condenser (ie the outdoor unit) are fasten to the bracket or flooring.

10. Listen to the condenser for any abnormal noise/sound and vibration. Have the installer rectify the noise/sound if there are.

11. When the system is fully charged, take a photo of the suction gauge pressure reading for reference. The suction pressure should be closed to 120 psi for R-410A gas.

12. With the system running, check the service valve ( the place that the manifold hose is attached to the condenser) with soap water for leak. Leaking can be confirmed when bubbles form around the valves.

Anyone who have knowledge may wish to add more to the above list.

The above are my opinion and hope that they are useful.

Hi, understand from the Mitsubishi catalogue that the StarMEX systems (depending on the model) have the following:

1. Anti-Allergy Enzyme Filter
2. Electrostatic Anti-allergy Enzyme Filter
3. Catechin Plus Pre-Filter
4. Double Air Cleaning Filter
5. Nano Platinum Filter
6. Plasma Quad

Hope that the above are useful.
