anyone using midea aircon?

[north3]

jin sad..

talking about this.. my panasonic fan coil went dead 2 days back.
initially thought was remote issue..
totally cannot powered..

now thinking if i should just get a new one or repair.
as the aircon is around 10 yrs..
using R410a gas type

10 yrs no need to think so hard. Just change! My compressor broke down after 1.5 yrs.

Used 2 different brands over 20 years lol. All no issue lasting 10 years. Sanyo, Toshiba. Not even big names. But sadly, now not so popular anymore.

plastic very thin so panels tend to vibrate and rattle, need to use foam tape to cushion

My previous Sanyo last for 14 years. Heard it's taken over by Matsushita (?) , It has its own strong aircon brand so it kill sanyo aircon n only keep its battery biz.

Wow... Read the reviews , it seems like their electronics many problems but worst is their services. And now Toshiba under the same company, so beware

matsushita is panasonic holding company, so it should be ok ba

actually their battery brand also sold to panasonic. eneloop now panasonic

Anybody used Haier or Gree aircon b4?

thanks. learn something new again when i check for R32 copper thickness

R32 refrigerant aircon, recommended pipe thickness is no less than 0.8mm. as R410A operates at slightly lower pressure than R32.
sauce: https://www.manualslib.com/manual/1175421/Panasonic-Cs-Vz9ske.html?page=48


in short R32 need SWG21 or SWG20 but most installer give SWG22 which is only 0.71mm

A lot installer still live in '80 mindset including xxxxxcity also push 0.71 copper piping, they still think they using R22 gas. Biggest installer doesnt mean the best...

Most installer NEVER comply to manufacturer requirement, cause they know consumer know nothing about it.
Common fault:
1/ Wrong piping size for R32/R410A
2/ brazing of copper pipe without nitrogen
3/ over /under torque coupling
4/ contaminate of equipment gauges, piping.
5/ never do vacuum
6/ missing ground wire from indoor FCU to compressor
7..... too much to itemises
No matter which big brand such as daikin, mitisubishi etc, your aircon eventually will break down in 2-3years. Consider yourself lucky if your aircon survived 5yr+++ ( those inverter aircon).

till now still finding a installer but hard. those that i can know, i try to see how they do, if i dont see them vacuum, i just ask them something related to vacuum to hint them. pipe thickness etc...


all ac sales person give me blackface when i correct them on the pipe thickness

There was once... 2 years ago, I spoke to a Daikin authorized installer, asking them to provide a quote for my parents' 3-room HDB house. The quote they provided stated the use of 0.71 copper piping. So I asked why they didn't follow the standard and requirements. The installer explained that if they quoted SW21 piping, it would be more expensive, and consumers might not choose their services.

They even mentioned that other 'major players' in the industry also quote SW22 piping. Additionally, they mentioned that they only use SW21 for condos because the aircon piping in condos is hidden in the ceiling, and mistakes are costly in such installations.

no wonder, all want money so all cut corner to give cheaper quota.

what drainage size and insulation size you choose?

thanks

didnt know vacuum pump take 15min then shut off the valve with pump and waited another 15min to make sure there no leak, then pump in 1 pound of gas into the system and waited again for another 5 to 10min to make sure there no leak under pressure, then remove the service port (it will lose some gas) then fully release the gas into the system

i doubt SG will do until like this

Actually, the size of PVC piping plays a relatively minor role in aircon installation. Standard 16mm piping is more than sufficient for home units, whether they are in a housing development board (HDB) flat or a condominium. The variation in discharge rate is minimal and mainly influenced by environmental humidity.

However, it is important to note that while the piping size is not the most critical aspect, owners still need to take responsibility for maintenance. If air conditioners are used daily in a normal room environment without the use of essential oils or similar substances, it is recommended to perform maintenance every 4-5 months. This involves using a wet and dry vacuum cleaner for 15-20 minutes sucking the discharge piping, and slowly pouring tap water from a PET bottle into the indoor fan coil condenser one by one.

For homes located near industrial areas, where there is dust or the use of joss incense or essential oils, more frequent maintenance is advisable. This simple 15-20 minute maintenance routine can help prevent pipe blockages and save you from falling victim to unscrupulous industry practices.

thanks a lot, for sharing, it hard as first time home owner, so many thing to learn.

i thought of getting Steam cleaner for the fin and wet and dry vacuum cleaner (TB can liao) for the pipe

Regarding the insulation tube:

There are many brands available, such as Thermaflex, Armaflex, K-Flex, Aeroflex, and others. The list could be quite long. Each brand offers various part numbers due to differences in thickness, density, and fire rating category. Generally, thicker insulation is better, especially for home insulation where thicker and less aesthetically pleasing trunking is used. The most recommended thickness is usually 1/2". Some brands also indicate a fire rating classification, such as Class 0 (Fire Propagation) or Class 1 (Spread of Flame), which adhere to the British Standard 476 Fire Tests. However, in the case of a small unit like an HDB or condo, the difference between Class 0 and Class 1 might not matter much unless you live in a multi-story or large unit.

Typically, installers will provide the cheapest option of 1/2" thickness from a brand that meets either Class 0 or Class 1 fire rating.

Each insulation tube also requires a factory-standard method of jointing. Unfortunately, many unprofessional installers use only black electrical insulation tape, which is considered a bad practice. In reality, there are various adhesives available specifically designed for joining insulation tubes/foams. Some installers may use a single can of PVC adhesive for both PVC piping and insulation tubes.

i just learned that there this new insulation, ArmaFlex TwinTube , k-flex split twin etc............ in short it a pre-insulated system solution (The system consists of copper pipe(s) and insulation material (PE).


manufacturer require 8mm thickness and this manufacturer pre-insulated system solution is 9mm which is more then enough cause manufacturer insulation is way better then any human who do insulation

I'm not sure if I understand you correctly, but there are pre-insulated copper pipes available in the market for several decades now. These pipes come already vacuumed and can be easily installed by users using quick couplings. The pressure is equalized when connected to the system, so there is no need for vacuuming too.

a robot does the installation?

i didt know until few day ago. my research failed me. heng i have not buy yet, so no now i ask for pre-insulated like armaflex spilt twin

yes pre-insulated is done by robot
