Air conditioning systems have become an integral part of our lives, providing us with much-needed respite during the scorching summer heat. However, have you ever wondered about the crucial component that makes these systems function effectively? That’s right, it’s the air conditioner gas. Air conditioner gas, also known as refrigerant, is a vital substance responsible for the cooling process in air conditioning systems. But what exactly is air conditioner gas, and how many types are there? Furthermore, how do professionals measure air conditioning gas pressure correctly to ensure optimal performance? In this article, we will delve into these questions, exploring the different types of air conditioner gas and the proper techniques for measuring its pressure, shedding light on an essential aspect of air conditioning technology.
Air conditioning gas is an important component in air conditioners and has a great influence on the cooling performance of the machine. Therefore, you need to know when to refill air conditioner gas for the machine to operate smoothly. Let’s find out what air conditioning gas is with Thptlaihoa.edu.vn, there are several types and how to measure the correct air conditioning gas pressure right away!
What is air conditioner gas?
Air conditioning gas is a refrigerant that is responsible for transporting heat vapor from a place with a lower temperature to an area with a higher temperature. The heat dissipation of the air conditioner helps to maintain the room temperature as set.
Therefore, air conditioning gas is an important and necessary component to support the air conditioner, helping the air conditioner to generate the right temperature.
Popular types of air conditioning gas
Each type of air conditioner will be suitable for a certain type of air conditioning gas to help the machine operate more optimally. Currently, air conditioners on the market often use 3 popular types of air conditioning gas as follows:
- Gas R22: is a very common gas used with about 70% of today’s air conditioners. This gas has the advantages of low cost, easy maintenance, non-flammable and non-toxic to users. However, R22 gas is harmful to the ozone layer and leads to environmental pollution , so it has been banned for use in some countries.
- Gas R410A: is a gas invented to replace R22 with a more volatile chemical configuration. The cooling capacity of R410A gas is also improved by 1.6 times compared to R22. Therefore, R410A is the solution with less environmental pollution , more efficient use and more energy saving than R22.
- Gas R32 is the latest improved gas, which can replace both R410A and R22. Gas R32 can reduce emissions by 75% , support deep cooling and save much more electricity. In particular, you can switch to using R32 gas immediately if your air conditioner is using R410A gas because these two gases have the same pressure .
How to measure air conditioning gas pressure
Preparing instruments
To measure air conditioning gas pressure, you need to prepare some tools as follows:
- A wrench
- A screwdriver
- An air conditioner gas meter has the unit of measurement Psi.
Steps to measure air conditioning gas pressure
- Step 1: Remove the protective board on the heater of the air conditioner with a screwdriver.
- Step 2: Remove all screws securing the lock on the gable and ejector.
- Step 3: Turn on the air conditioner and let it run stably at the lowest temperature.
- Step 4: Screw one end of the gas meter into the air conditioner’s head and wait for about 1 minute to measure the pressure.
- Step 5: Observe the pressure measurement displayed on the gauge screen.
When to measure air conditioning gas pressure?
You need to measure the air conditioning gas pressure when you notice some of the following signs:
- The air conditioner, the air conditioner is frozen and there is no heat discharged to the outdoor air conditioner.
- The cold is too weak or the air is not cold when the air conditioner is turned on.
- Low air conditioning gas pressure is displayed on the remote .
The most standard gas pressure table
Gas type | R22 | R410A | R32 |
Rated gas pressure when the machine is running: | 60 – 78 Psi | 110 – 130 Psi | 125 – 150 Psi |
Gas pressure when the machine is not running: | 140 – 160 Psi | 250 Psi | 240 – 245 Psi |
Standard current: | 3.9 – 4.2A | 5 – 5.5A | No information |
Gas charge volume: | 0.65 kg | No information | No information |

In conclusion, air conditioner gas plays a vital role in the efficient functioning of air conditioning units. It is responsible for absorbing heat from the indoor air and releasing it outside. There are two main types of air conditioner gas: the older generation of refrigerants (such as R-22) and the newer, more environmentally friendly ones (such as R-410A). It is important to note that the older refrigerants are being phased out due to their harmful effects on the ozone layer.
To ensure that an air conditioning unit operates smoothly, it is crucial to measure the gas pressure accurately. This can be done using a pressure gauge, which is a device designed to measure the pressure inside the system. To measure the gas pressure correctly, one must first locate the access port on the air conditioning unit. This port allows for connection to the pressure gauge. The pressure gauge should be properly calibrated and connected to the port, ensuring a tight seal. Once connected, the reading on the pressure gauge can be observed.
It is crucial to highlight that measuring air conditioning gas pressure should only be performed by qualified professionals or individuals with sufficient knowledge and experience in handling refrigerants. Mishandling or improper measurement can lead to system damage or personal injury. It is recommended to consult a certified technician who can accurately assess and maintain the air conditioning unit, including measuring the gas pressure correctly.
Proper maintenance and regular measurement of air conditioning gas pressure are essential to ensure optimal performance and extend the lifespan of the unit. By understanding the basics of air conditioner gas and adhering to appropriate measurement practices, individuals can enjoy dependable and efficient cooling in their surroundings while minimizing their environmental impact.
