What is Refrigerant Gas? Understanding and Comparing Common Types of Refrigerant Gases.

1 What is Air Conditioner Gas?

Air conditioner gas, or refrigerant, is a vital component of your air conditioning system. It is responsible for absorbing heat from the indoor air and releasing it outdoors, ultimately cooling your space. This gas undergoes a continuous cycle of evaporation and condensation within the system, facilitating heat transfer from warmer to cooler areas.

The unique property of this gas is its ability to transition between a gaseous and liquid state, depending on pressure. When the gas absorbs heat, it evaporates and becomes a gas. Conversely, when it releases heat, it condenses and returns to a liquid state. This process enables your air conditioner to effectively cool the air in your room.

2 Common Types of Air Conditioner Gas

R22 Gas

R22 gas was the first type of refrigerant used in air conditioners and is commonly found in budget-friendly models from brands like Panasonic, Daikin, LG, Samsung, and Midea. Despite its widespread use, R22 is known to cause environmental harm, particularly ozone layer depletion. As a result, many manufacturers have discontinued its use and opted for more environmentally friendly alternatives such as R410A and R32.

R22 gas was initially used in air conditioners

Pros:

• Easy maintenance as you can top up the gas without fully draining the existing gas.
• Non-toxic and safe to use.
• Does not cause explosions or fires.
• Affordable price point.

Cons:

• It can deplete the ozone layer, leading to a ban on its use in certain countries.
• Inefficient and costly in terms of energy consumption due to its low compression index.
• While non-toxic, high concentrations of this gas can cause asphyxiation.

R22 gas is easy to maintain and cost-effective

R410A Gas

R410A gas is produced with similar chemical components to R22 but offers a higher evaporation rate, significantly reducing its impact on global warming and protecting the environment. It is widely used as a replacement for R22 to mitigate environmental concerns.

R410A gas has a similar chemical composition to R22 but reduces the greenhouse effect

Pros:

• Offers 1.6 times higher cooling efficiency compared to R22, resulting in deeper and more energy-efficient cooling.
• Environmentally friendly as it does not contribute to ozone layer depletion.

Cons:

• Requires storage in a well-ventilated area to prevent gas leakage.
• Difficult to maintain as you need to fully drain the remaining gas before topping up.
• Air conditioners using R410A gas tend to be more expensive than those using R22.
• Higher costs associated with gas charging and pumping compared to R22.

R410A gas delivers superior cooling performance and is environmentally friendly

R32 Gas

R32 is the newest type of air conditioner gas, widely adopted in Japan. It was designed as an alternative to R22 and R410A, offering improved environmental performance and energy efficiency. R32 is rapidly gaining popularity among consumers.

R32 gas is the most modern option available today

Pros:

• Environmentally friendly, reducing greenhouse gas emissions by up to 75%.
• Energy-efficient, delivering faster and deeper cooling compared to R22 and R410A.
• Similar pressure to R410A, allowing for a seamless transition if you already have an R410A air conditioner.

Cons:

• Challenging to install and maintain without specialized tools and gauges for this specific gas.
• Higher upfront cost compared to air conditioners using R22 or R410A gas.
• More expensive gas charging, pumping, and replacement costs.

R32 gas is environmentally conscious and energy-efficient
