so, indoor is non-inverter can control outdoor inverter compressor; doesnt inverter units have extra control wire

The guy did it. How...I dont know the technical, but it works. I guess is just work as the normal non invertor compressor.

He works in the plant doing manufacturing and assembling. I think he has done some trail and error in his house also.

why?

I notice a drop in my tnb bills when i change my sharp fridge to another sharp invertor...approx rm50 per month.

Not sure the aircond can have the same expectation if it is just running few hours occaionally.

Dear all Sifu in LYN,

I have to purchase 7 air cond for my new house due to budget constraints so i need to make a correct decision.

Master room (frequently on) - 1.5HP Inverter Panasonic/Daikin
Parent room (frequently on) - 1.0HP Inverter Panasonic/Daikin
Sibling room (frequently on) - 1.0HP Inverter Panasonic/Daikin
Study room (Rarely on) - 1.0HP Non-Inverter China Brand
Guest room (Rarely on) - 1.0HP Non-Inverter China Brand
Living Hall (Rarely on) - 2.0HP Non-Inverter China Brand
Dinning Hall (Rarely on) - 1.5HP Non-Inverter China Brand

1.) Can you all advice it is this arrangement is the most cost effective way?
2.) Which china brand aircond is most value of money? please recommend me.

Really appreciate advice form all SIFU. Thank you notworthy.gifnotworthy.gif

Buy all single brand for reference trouble shooting in the event of a fault.

Personally, I dont feel the different coldness between 1hp and 1.5hp.

For living hall, depending on layout, you can install 2 units 1hp at different location for faster cooling instead of one 2hp.

3 phase power supply ?

You meaning of single brand is all frequently on and rarely on also same brand? Then all will be go Panasonic. This is my original plan but now need to cut budget so decide to purchase 2 brand. My new plan was those frequently on (3pcs) will still continue go for panasonic while those rarely on (4pcs) buy either (media, haier, hisense or gree).

But among the 4 china brand i dont have idea which one is better but look like gree is out of list because dont have R32 gas

If 1.5hp and 1.0hp not much difference then i just downgrade all 1.5hp to 1.0hp

For living hall impossible to put 2pcs 1hp aircon because only got 1 conceal piping.

Yes 3 phase power supply.

Go according to your original plan.

When you buy in bulk, you can bargain for better pricing.

If you have budget constraint, you dont need to install all units. Study and guest rooms can wait since you rarely on.

I got two questions

a. Copper got two types a? thick and thin?

b. My aircond contractor said if want to use panasonic inverter, he suggest thick copper, it is make sense? because he said daikin inverter used thin copper while panasonic inverter used thick copper? Is there any problem using either thick or thin copper?

Layman answer ...

Thick is better than thin ... installation cost not much different if length usage is minimum .. e.g. back to back installation.

Guys how do we know if the aircond is out of gas? How often do you guys service your airconds?
*
1. Indoor unit blowing normal air.

2. Oil stained below blower of indoor unit or outdoor unit


DIY cleaning of air filter every 3 months.

Major service once a year

Seriously? Is the new fridge comes with 5 star rating?

I've changed 2 main aircond in the room to inverter (Sharp 5 Star) and only recently managed to see full one month usage, set at 21c use around 7-8 hours daily

Bills dropped from average $440 to $271 this month
Now thinking about the fridge and dryer

Invertor is oredi energy savings as claimed. I am not sure it comes with star rating.

During the MCO, my 13 year old Daikin aircon had problem as well. Bought the parts from the vendor above and swapped them out. The aircon is working fine now.

My Daikin 1.5hp (FTKD50FVM) kaput. about 10yo.  Press remote, but auto-off after a few seconds. 

Daikin Remote diagnosis is U4 (Malfunction of transmission between indoor and outdoor unit).

Non Daikin technician diagnose as PCB problem at compressor (Compressor - RKD50BVM (PCB Part No: D18531221)).  Daikin quotes RM658 just for the part......habis lah like that ..so mahal  bangwall.gif

Question;

1. Possible to get cheaper price for the same part ie the PCB D18531221? OEM ? [sorry, i just trying my luck  icon_question.gif )

2. Should i just forget about this aircond, bid it farewell and get a new one ? [ icon_idea.gif ]

If get a new one,  i would want to get;

A.  5 star rating,

B.  Inverter (as use several hours in bedroom)

C.  Last long, and cheap parts (Panasonic ?  Daikin Inverter - my recent experience - just b4 MCO - very noisy as neighbour complain - about 75 to 80db)

Please recommend....

tk you tk you.... rclxm9.gif

That is sure expensive. Pana 1hp is about RM100.

Shoppee do sell universal pcb for less than RM100. You can try if it works if is pcb problem as claimed by the technician.

Thanks bro. A few more question ya...

1) The copper runs I guess we need to buy externally ourselves?

2) Do we need to buy the copper coil bending device?

3) I have checked on youtube seems like we need a number of tools also like a torque wrench?

4) Insulation any recommendation?

4) Outdoor unit bracket is also separate purchase?

I dont have answers for your question but I do have a question ...

Existing unit replacement, but the old unit is quite old 10 years or more, R22 gas, so I guess the pipes etc need to be changed.

My perception is that older pipes are of better manufacturimg quality than current.

I will install without new piping. Take some risk.

The possible problem is gas leakage at old piping joints. When that happen, then only pening.

Dont get stress over the piping. If you dont want double work, go for complete overhaul of the piping.
