Hi all the HWZ air-con specialists
Intend to get a system 3 for my new flat for 3 bed rooms (not for living room) and current targeting the followings:
1. Daikin inverter system 3 3MKD75DVM / FTKD25 X 3 (3 ticks R22)
2. Daikin inverter system 3 3MKS50ESG / FTKS25 X 3 (4 ticks R410A)
3. Mitsubishi Electric inverter system 3 MXY3A28 / MSYGE10VA X 3 (4 ticks R410A)
Would appreciate if you guys could advise me on the followings:
1. My usage is mainly for the master bedroom (8 hrs a day) and the study room (4 hrs a day). The balance unit at the guest room will only be occupied occasionally. Should I get an inverter or non-inverter air-con for my usage?
heard more than 8hrs(or 12hrs) than use inverter. but than lesser usage from inverter also will save electricity.
2. I read that air-con compressor is noisier for non-inverter models, is that true? As the air-con ledge is located just behind the wall which my bed will be lying against.
for inverter, i dont tink it will be tat noiser, as when the room hav reached close to temp set, than condenser will run slower.
3. For 3 bed rooms (HDB 4 room flat so very small lol) is Daikin 3MKS50ESG sufficient?
3MKS50ESG will be sufficient if u dont always on all 3 units at the same time. it will take a longer time to cool the room if all 3 units is on. if yours a new flat? cos i knw newer flat bedroom is smaller.
4. Does the above Mitsubishi Electric models come with self cleaning dryer to prevent mould and fungus growth? I heard Mitsubishi Electric is more efficient however I am concern about the potential bad smell caused by the lack of auto self cleaning dryer feature.
tat self cleaning is actually to run fan mode for some time b4 u off the unit. i tink daikin inverter shld hav tat similar function.
5. The supplier will provide upgrade to armaflex class 1 insulation and G23 copper. Is it sufficient?
class 1 or class 0 also doesnt matter. cos tat is fire rating. G23 is gd enough. anyway for insulation, 1/2 inch is recommended.
6. For the drainage PVC pipe, am I recommended to upgrade from 13mm to 16mm?
up to u. bigger diameter pipe will take very very long for the jelly-like substances to clog your pipe.
Hope all the experts here could give me some of your precious opinions on which model should I get based on my usage.
Many thanks!
