Such news is not very much but sometimes keeps on coming. Usually, in all these cases, gas was leaked from AC and people sleeping in the room died of suffocation. In some countries, deaths were reported in rooms with AC gas or poor ventilation in unauthorized manner.
– Get gas leaked in AC
– Do not be the right ventilation
– Old or poor maintenance AC
In such cases, accidents happen again. Although the ACs that are engaged in us and your homes are quite safe, but even then sometimes they also get accidents.
Should the room be completely closed while running AC
-The doors and shirts should be kept closed while running AC so that the cold air does not come out. The room temperature can be controlled quickly. This also saves electricity, but if AC is to be run all night, then there should be such a place in the room that ventilation can be done. Therefore, there is no harm in opening the door of the room lightly.
– The room should be completely ventilated (ventilation). That is, if the gas leak of AC in the room, then it is necessary to have any way to get out of the air or any means of oxygen.
-If AC and room stay in the room for several consecutive hours, then from time to time, open the door should be allowed to come in a little fresh air. This keeps the oxygen level. The level of co₂ does not increase.
– The room should never be closed tight.
-Let the fresh air enter for at least 5 minutes every 2-3 hours
– Make sure to get refrigerant leak test in AC servicing.
-It is very important to check and servicing AC gas leaks 1-2 times a year.
What gas contains air conditioner?
-The old AC system used R-22 (chlorodifluoromythane-HCFC) gas but it damages the ozone layer, so now its use is restricted.
-R-410A (Poron, Purfriercent). Modern AC is most commonly used. Ozone is friendly but it has more global warming potential.
-R-290 (propane-hydrocarbon refrigerant). The best option for the environment, the ozone layer causes very little damage. Being flammable requires caution.
Gases used in initial air conditioner
R-12 (dichlorodifloromythen-CFC). Very old AC system (1930s-1990s) was used. Ozone used to cause great damage to the layer, so the Montreal was banned under the protocol.
Ammonia (NH₃). Very old refrigeration was used in the system. Being poisonous and explosive, the domestic could not run in AC.
When R-32 becomes dangerous
The R-32 (defloromythen) is an HFC (hydrophlorocarbon) refrigerant used in the modern inverter AC. It is ozone-friendly, but there is flammity. It can catch a small amount of fire. If the AC system is leaked and the gas construction reaches 13-29% there, then the fire can catch if an ignition source (eg spark, lighter, switch) is present.
Especially who should be taken care of?
– Elderly
– Young children
– People with asthma or breath
– For those living in AC for a long time
Some big accidents of AC
2. Vijayanagar (Karnataka) (April 2022) – After the gas leak at night, there was a short circuit in AC, causing a fire and a whole family (parents and two children) died.
4. Costco Store, United States (April 2024) – The refrigerant gas leak spread “white cloud”, in which 1000 people complained of suffocating but they were saved, no one suffered a serious injury.
