I am using R22 refrigerant air conditioners on inverter type piping. So far no problem.thanks This post has been edited by *CG*: Jun 29 2013, 11:21 AM |

QUOTE(*CG* @ Jun 29 2013, 11:21 AM) okok...noted that. pheeew...relief than..another thing about the gas copper piping horizontal line, it must be heading-downwards to the Aircon unit, anyone knows / can confirm that? reason is, the contractor said my piping outlet is facing upwards to the Aircon. So, the contractor must push very hard to tilt about it. (I'm not talking about the water pipe) thanks |

Anyone use inverter A/C with standard piping?
Any issue and feedback? |

Inverter and Non-Inverter use different Piping.

i'm using 1hp normal a/c at the moment, however the room is not cold enough
Therefore im thinking of upgrading to 1.5hp But R22 A/C is difficult to find now........ Can i buy R410A (non inverter) and use back my piping?.. My piping all concealed , came with house. (5 years old). I heard need to flush the pipe and make sure it is clean.. |

QUOTE(Richard @ May 3 2016, 11:01 PM) Bad advice since you don't mention anything about why the old piping cannot use a different refrigerant.. Apa la awak!!!This is Lowyat Forum. Not a place to argue. Inverter and Non-inverter use different piping. Since Non-inverter used thin pipe. Inverter use thick pipe, as spreeee mention it. Think properly before you post. In Aircon Discussion V3. No one posted bad advice like you. You are junior member in Lowyat Forum, not senior member. Post wrong or right doesn't matter, other people will correct it. Don't think this is the place to get 100% answer. This post has been edited by TXSim: May 3 2016, 11:09 PM |

QUOTE R22 vs. R410a refrigerant R22 refrigerant: As of 2010 is no longer allowed to be used in newly-manufactured air conditioners Contributes to the depletion of the ozone layer Is less capable of absorbing and releasing heat than R410a refrigerant, making it the less efficient refrigerant Is becoming more and more expensive as its use is phased out R410a refrigerant: Is approved for use in all newly-manufactured air conditioners Does not contribute to the depletion of the ozone layer Is better at absorbing and releasing heat than R22 refrigerant, making it more efficient to use Requires the use of tougher and more durable air conditioner parts, which reduces the risk of your system overheating and breaking down What is not mentioned is R410a used in Inverter Air conditioners runs at a higher pressure than R22 thus the need for thicker copper tubes.. But the regular R22 copper tube can still withstand that higher running pressure only it doesn't have the same safety factor of not springing a leak.. I would advice save money, use back the existing conceal copper tubes with the inverter aircon.. a properly installed R22 copper tube can easily handle the pressure .. Edit* Just to add.. If you have an installer asking you to replace R22 piping it's not because there's anything wrong with the existing pipes.. My brother says the same thing to his customers all the time.. the installer (like my brother) makes more money ... like i said he installs aircon..

QUOTE(Richard @ May 3 2016, 11:19 PM) Its a discussion, my brother installs aircon and (copy pasted) hi there, since it's 2017, mind to ask are all current aircons sold in market (inverter/non-inverter) all using R410A gases? or by chance non-inverters still using CFC gas?What is not mentioned is R410a used in Inverter Air conditioners runs at a higher pressure than R22 thus the need for thicker copper tubes..

My brother says the same thing to his customers all the time.. the installer (like my brother) makes more money ... like i said he installs aircon.. and anyway to check current piping if they are inverter ready? non-inverter pipes they use pvc, normal metal? inverter pipes use brass? so inverter pipes should look gold/bronze color? and to figure out it's spec for R22 or R410a, we have to measure the inner diameter & thickness of the pipe (can only measure the outlet since bends are hidden). and can you tell us the recommended inner diameter & thickness for both R22 & R410A gas? can R22 run efficiently on the bigger & thicker R410A pipe? also i would assume it's safer to run smaller hp AC with R410A on R22 pipe as smaller AC have lower pressure output?

QUOTE(owj @ Dec 8 2017, 10:30 AM) Just a question. if I want to install a non-inverter aircond using inverter piping I presume it is ok? Short answer definitely but the issue is not inverter or non inverter but what type of gas is used in the inverter or non inverter AC.Mostly what's sold now uses R410a gas with R32 as the replacement over that. Older AC we grew up with uses freon and then R22 which was was phased out. R22 based AC are current install base in many homes but market available are now R410a and in appearing recently in small numbers R32. Turning the question around should be what pipe thickness is safe for R410a/R32 based AC. Thus, it boils down to what thickness of AC copper pipe is able to withstand the operating pressure of R410a and R32 with a high margin of safety. Thickness is stated in standard wire gauge numbers but now commonly in millimetres. Older pipes uses to be gauge 25 (0.51mm), 24 (0.56mm) or 23 (0.61mm). These are ok for R22. R410/R32 however operates at 1.6/1.7 times higher pressure than R22. The minimum thickness recommended for their use is 0.71mm or 0.76mm but now many AC manufacturers specify 0.81mm minimum. There are AC pipe manufacturers do manufacture other thickness like 0.89mm, 0.91 mm or 1.0mm and higher. There are AC like multi split systems that could require thicker like 0.9 or 1.0mm or more. They are also used in [update: VRV] or in tandem with cooling and heating that are only common in European markets. That said, follow the manufacturer specification in the installation manual. Panasonic and Fujitsu normally recommends 0.81mm pipe thickness for R410a. A good example is seen here. This post has been edited by halcyon27: Dec 9 2017, 11:38 AM |
