Now.. Do we know if the a/c is using R32 gas or R410a gas or even R22 gas?

Scared kena tipu with salesman.. Said R410a but sell R22..

I was looking for aircon services , I stay at usj , any shop can intro?

On each Aircon compressor or model has mention it model was R410a or R22 or R32 only.

Actually the correct call it outdoor unit was condenser, not a compressor unit.

Oh ok2.. Thanks for the info..

But it just a sticker, right?

Is there any other way we can know which is which?

R32 is the coldest now. R410 also got non inverter. check daikin in july

Nope, there's no such thing of best gas to get on buying an air cond
Don't listen to some fanboys saying.
What important is how long you are going to use, the setup of your room(type of brick used, sun facing where) and the size of the room.
A 22ft*10ft room you need at least 1.5HP of air cond.
Choosing air cond still Japan > China > India > Vietnam > Korean.
Now is summer, so you can't have down time on your air cond. So pick the right brand will be good.

I mentioned in [edit: another] thread before. R32 supply and distribution needs some rethink on safety before it is widely used here. See here

The gas cylinder has to be kept in 60bar.
60bar is a high pressure steam system used in power plant to generate 132KV of voltage and 30MW of power.

Hello fellow forumers.

I've tried to read thru the thread and since I'm a newbie I got confused with all the technical wattage, gas types, brands, etc.

I'm planning to buy an aircon for my room. It's about 10ft by 10ft( i presume a 1.0hp aicon would be sufficient).

The plan is to get an aircon which is silent and energy saving(lowest impact on monthly electricity bill). I plan to use it for maybe 4 hours per night and up to 10 hours per day during weekends. It doesn't have to be super cold (24-25 degrees C is enough for me).

Which brand would you recommend + inverter or non inverter?

Also my room doesn't have any preset place for aircon installation(it's an old basic house) and no extra electricity outlet for the aircon. How much could I expect would be needed to install these things?

Goodness....refilling or filling might be a nightmare. I imagine it could easily burst the AC pipes unless proper rigging and precautions are used.

The PERFECT choice for YOU is the Panasonic Inverter Econavi air conditioner. It fits your requirements of silent and lowest impact on energy bill. With the Econavi feature turned on I don't think there's any air conditioner in the local market that can beat it. Of course, it won't be as cold which fits your requirement of not needing to be super cold.

I got my unit installed for RM1500. But I had an existing inverter air conditioner they replaced.

It will be launch in June?

sharp officer told me all green gas should be flammable including r410 liao. if you wanna be safe use r22

Ok now am a bit confused here..

R22 going to discontinued yet R22 is safest among three?

yes safest not flammable but deteriorate ozone.

Ok.. Dangerous to ozone but safe to home owners..

Not a win win situation isn't it?

To get a picture of what R32 is like, let's take a view of it here. Bear in mind the link goes back 2 years ago when supply was scanty before they (suppliers like Actrol and Heatcraft amongst others) got their act together due to the safety valve requirements. R410a is 50% R32 and 50% R125 which acts as a flame retardant. But R32 is only mildly flammable.

Sorry.. Are we talking about R32 or R22?

As what I read above R22 is safest yet hazardous to ozone..

Your link meant for R32?

i dont mind paying extra RM200-300 for an inverter unit ... and i dont like my outdoor unit keep on and off , the noise is annoying .... my sharp 1.0hp inverter run in full speed for 30mins and after that no noise at all.... for the whole night ....
