The Difference Between R410A and R32
As if buying a new air conditioner isn’t already a tough choice, now we also have to decide between two different refrigerants as well. Of course, we’re talking about the well-established R410A and the newly introduced R32.
We use the term “refrigerant” to refer to several types of gases that we use as cooling agents in air conditioners and other similar devices. The gases are insoluble in water and can travel as far up as the stratosphere, thanks to different chemical reactions.
We differentiate between refrigerants based on:
their chemical structure
their environmental impact
the type of device that uses them
What makes certain refrigerants stand out is their impact on our environment. For example, both R32 and R410A belong to a group of gases called hydrofluorocarbons. Their ODP (ozone depletion potential) is 0, which makes them eco-friendly.
Both refrigerants belong to the same group and share the same ODP.
However, in this article, we will discuss their differences.
Which one is better?
Let’s find out. But first, here’s some general information about these two refrigerants.
What Is R410A?
In 1991, an American company by the name of Allied Signal invented and patented the R410A refrigerant.
Five years later, the gas found its way into residential air conditioning units, replacing R22 in the US, Japan, and Europe.
In 2010, the US completely phased out R22. Since then, R410A has been the standard for all new air conditioners in the country.
Unlike other refrigerants, R410A operates at much higher pressures. Therefore, handling it requires the use of equipment that is suitable for such conditions.
Even though it consists of two different gases, it still has a constant boiling point. Because of that, refilling a pressure vessel with R410A should be relatively easy and without any leakage.
In contrast to haloalkane refrigerants, R410A does not contain chlorine or bromine.
Instead, the gas contains only fluorine, hence its non-existent ODP. That is the reason why R410A became widely available, replacing R22 in the process.
While R22 has a global warming potential of 1810, R410A exceeds it with a GWP of 2088.
However, the latter largely reduces power consumption. Therefore, its environmental impact is drastically lower than that of R22.
What is R32?
R32, better known as difluoromethane, is an organic gas, much like R410A. With an ODP of 0, the two gases are also equally harmless to the ozone layer.
Still, R32 has a GWP of 675, which is significantly lower than those of R22 and R410A. That makes it a seemingly better alternative.
R32 performs well in terms of pressure drop and heat transfer. It’s a grade A2 gas, which means it is mildly flammable.
In spite of that, R32 has been successfully used for many years now, most notably in China, India, and Japan.
In order to mitigate the risk related to its flammability, experts recommend using heat transfer equipment that has a low refrigerant charge.
Interestingly enough, R32 is a component found in other refrigerants. For example, by combining it with R125 and R143a, we can create refrigerants R407A and R407B (through E).
R32 is also one of two gases that make up R410A, which we described above. Contact Aircon Service Puchong for more information

How To Buy Property For Big Profits
Investing in anything is a risky business these days. You wonder whether to buy stocks, bonds, mutual funds, or unimproved land. Well, it is probably good to have a little of everything in your portfolio. And if you invest in property, you will need to do a bit of research.
Decide on the kind of property you want. It might be commercial, or it may be residential. If you already live in your own home, you may want to buy another one to rent out. Or maybe you would consider a duplex.
If income is your goal, you need to know something about the potential of the property, such as how much rent can be charged for it. And you should also know something about the neighborhood. If it is in a high crime area, there is a chance that your tenants may suddenly not want to live there and they may leave unexpectedly. A vacant house in a high crime area will probably be vandalized, and your investment will, of course, be negatively affected.
Having a mortgage on an investment property can be a great burden. If you intend to rent it out, you would probably like to get the full monthly mortgage price, plus some part of the property insurance and taxes. If the rent can also cover some maintenance of the property, such as money to hire a landscaper, this would solve a lot of problems.
If you are in a nice neighborhood, the property should be desirable enough to collect the rent you want for it. This way, the property has the potential to pay for itself.
If it is land that you are interested in, it should be in an area that is easily accessible. A main road would attract developers to build on it. And if the electricity and sewer system is in place in the area, your land will be worth much more.
When you invest in property, you need to know what you are investing in. Huge mistakes can be made when due diligence is not performed. When you purchase property that has the potential for an increase in value in the future, this could be your best investment.
