R32 gas is a type of refrigerant gas that is used in aircon units. For an aircon system to work, gases like R32 must be present and maintained at certain levels within the system. When we simply refer to “R32”, it assumes that the R32 is either “pure” or of high enough purity to run air conditioner systems without any issues.
R32 is extremely popular for air conditioning. If you are interested in the pros and cons of this gas, I’m here to clarify things for you.
Environmentally friendly: Compared to R410A, R32 has a much lower GWP of 675 which makes it more environmentally friendly. This means there will be minimal impact on the ozone layer and global warming.
Energy efficiency: The low GWP means that less energy is consumed by your air conditioner, and therefore lower electricity bills. And because it has a higher cooling capacity than other refrigerant gases, R32 uses less refrigerant per kilowatt of cooling output. The result is lower costs for installation and running costs over time.
As a single component gas: it takes up less space in the AC unit’s compressor, which makes the unit more compact and efficient than 2-component refrigerants like R410A. The single-component also allows for easier maintenance during servicing because there is only one refrigerant to handle.
It generates a lower discharge temperature than other refrigerants: This means that under normal operating conditions, there is no need to apply special measures to cool down its discharge temperature, reducing power consumption and saving you
R32 aircon gas has a zero ozone depletion potential (ODP): While R410a has an ODP of 0.04, R32 has a rating of 0 which means it does not deplete the ozone layer at all.
Smaller Pipework: R32 systems operate at lower internal pressures, so they require smaller piping and ducting. This allows for more flexibility in the design, while also reducing installation costs.
Highly flammable: The main disadvantage of this refrigerant is that it is highly flammable when compared to other gases like R22, R410A, etc. This means that extra precautions will be taken during installation to ensure that there are no leakages or any other issues that might.
More expensive: Whilst R32 air conditioning units are more energy-efficient, this does mean that they are more expensive than other air conditioning systems.
High-pressure Gas: R32 refrigerant also has a higher pressure than other gases so it requires different piping materials. If you install an R32 system in your home, make sure that your installer uses certified R32 parts to avoid damage to your air conditioner and to avoid any safety risks.
High installation cost: The higher initial cost for installation is due to the need for specialized pipes when installing new equipment or replacing old ones in existing buildings/structures (this may increase your overall bill); however it will pay off over time by saving money on electricity bills every month.
