<\/span><\/h2>\nAir conditioning gas, also known as refrigerant, is a form of liquid used in the refrigeration cycle.<\/p>\n
This refrigerant changes from liquid to gas and vice versa. During this conversion, it will absorb hot air from the room and deliver it to the outdoor unit. Then push the hot air out.<\/p>\n
Gas in the outdoor unit, after passing through the throttle, will be converted from liquid to gas, the temperature will be cold. Air conditioning gas is led to the indoor unit through copper pipes. This cold air is blown into the room by the indoor unit fan, and at the same time sucks the heat out of the room. It is then sucked into the compressor to be compressed into an extremely hot liquid. Hot refrigerant is sent to the outdoor unit, thanks to the fan blowing hot air into the room and back to the throttle valve to continue the cooling cycle.<\/p>\n
Therefore, it can be said that gas is a very important source of energy for air conditioners. Without gas or without gas, the air conditioner cannot cool or heat, and if it does, it is difficult to achieve maximum efficiency.<\/p>\nRecharge additional gas for air conditioner easily<\/em><\/figcaption><\/figure>\n<\/span>Signs to recognize when to refill air conditioning gas?<\/span><\/h2>\nAir conditioning gas is the main cause of determining the cooling mechanism of the air conditioner. However, during operation. Due to many reasons, the element that makes gas in the air conditioner can be lost, leading to a condition where the air conditioner lacks gas or runs out of gas. We need to recognize some signs to promptly supplement as follows:<\/p>\n
\nThe air conditioner is still running normally, but the cold air blows out weakly or not at all, only the fan is blowing<\/li>\n The air conditioner blows out smelly<\/li>\n Air conditioner leaking water<\/li>\n The air conditioner is frozen in the indoor unit<\/li>\n The outdoor unit does not have hot air blown out<\/li>\n Air conditioner shows a circuit fault<\/li>\n The air conditioner is running automatically or running for a long time without stopping.<\/li>\n<\/ol>\n<\/span>Does the new air conditioner need to be recharged with gas?<\/span><\/h2>\nIf your air conditioner is a 1-way air conditioner. You should have your air conditioner serviced at least once a season. Normally, new air conditioners will need additional gas after 1 year of operation. However, there are still exceptions.<\/p>\n
For example, perforated indoor unit, perforated outdoor unit, perforated copper pipe, loose jacco\u2026. leading to a lot of gas loss in a short time, the time needed to pump gas for air conditioning can be shortened.<\/p>\n
However, there is a small tip for customers, is that every year we need to maintain the air conditioner, and in the process of air conditioning maintenance for customers of dienanhhungdung.net there is always a free gas test for customers. That is the advantage for customers to have the most accurate gas check to see if they need to pump gas for air conditioning every year at the beginning of the season.<\/p>\n
If your air conditioner is a 2-way air conditioner. You should have your air conditioner serviced at least twice a year at the beginning of each season and will be checked free of charge to see if you need to add gas to the air conditioner?<\/p>\n
\nNotes<\/strong>: In addition, if you use the air conditioner with a lot of frequency. If you are on a large road surface with a lot of smoke and dust, then increase the number of maintenance times to 3-5 times\/year.<\/li>\n<\/ul>\n<\/span>How much gas is enough to refill the air conditioner?<\/span><\/h2>\nThe amount of gas charged for each air conditioner is different because it depends on the cooling capacity and the type of gas that the air conditioner uses. And it is measured in pressure unit is PSI<\/p>\n
After looking at the technical parameters of the air conditioner on the hot unit, the worker will know what the rated pressure of the air conditioner is, what gas is used for the air conditioner. Then measure the pressure. Compare with the manufacturer’s value, see if there is a shortage or not and how much is missing to proceed with the air conditioning gas pump.<\/p>\n
Air conditioning gas is compressed in the block in the air conditioner heater, with very high pressure. Conventional air conditioners that many families are using have a capacity of 9,000BTU – 18,000BT, a gas tank pressure of about 75 – 80 Psi.<\/p>\n
Air conditioning gas pump is the supply of enough gas according to the rated pressure of the machine. Let the machine operate in the best condition.<\/p>\n
For example, you need to charge gas for an air conditioner 9000BTU, equivalent to a gas pressure of 75Psi. Actual measurement is only 50Psi. That is, you have to add 25Psi ga more.<\/p>\n
<\/span>Types of gas commonly used in air conditioners<\/span><\/h2>\nTypes of gas commonly used in air conditioners<\/em><\/figcaption><\/figure>\nGas R22: is the first gas used on air conditioners, users do not need to vacuum when adding new gas. However, now manufacturers have limited the use of this gas because it contains ingredients that pollute the environment.<\/p>\n
Gas R410A: is a type of gas with a cooling capacity 1.6 times higher than gas R22, saving electricity and giving a deeper cold. Gas R410 requires users to vacuum when they want to pump gas for air conditioners.<\/p>\n
Gas R32: is a new gas on the market, recognized to meet GWP emission standards. Using R32 gas helps users cut emissions by up to 75%, preventing heat gain leading to the greenhouse effect. Similar to R410A gas, this type of gas also requires a vacuum before pumping new gas.<\/p>\n
<\/span>Choosing the right gas for the air conditioner<\/span><\/h2>\nOn the market today, there are two main types of gas commonly used are gas R22 and gas R410A. Gas R22 is an old gas, cheaper price and often used for machines with medium capacity. When recharging gas R22, just determine the amount of missing gas and pump additionally. Although easy to use, this gas is rarely used recently because it has had a bad impact on the environment.<\/p>\n
The type of gas that is being used today is R410A gas, which is not harmful to the environment, helps the air conditioner operate with a higher capacity, however, it is more expensive. When additional charging is required, it is necessary to drain the old gas and completely refill it for this type.<\/p>\n
Some air-conditioner companies, when selling to developed countries such as the EU, Japan, the USA, etc., have switched to producing air conditioners using R410A gas.<\/p>\n
If you are wondering which type of gas to choose, look at the air conditioner company that your family is using and choose the right type of gas.<\/p>\n
