Is refrigerator refrigerant toxic?

The refrigerator is a device used in every household. It is mainly used for preservation and is very helpful for storing food. However, the refrigerator can cool mainly because there is refrigerant in the refrigerator. Refrigerant is the key to the refrigerator's refrigeration. This thing is poisonous, but generally the refrigerant will not enter the food. It is placed outside the refrigerator's fresh-keeping cabinet. Let us understand how to add refrigerant.

How to add refrigerator refrigerant

1. The first step is to connect the refrigerator and refrigeration equipment to the system. However, when adding refrigerator refrigerant, you must ensure that the system equipment has been shut down before connecting the equipment.

2. Before connecting the system, close the high and low pressure valves, connect the high and low pressure gauges of the system and lock them, connect the vacuum pump, fill the interface and connect the interface.

3. The next step is to evacuate the system vacuum. This is a necessary step. Before evacuating the vacuum, the high and low pressure valves need to be opened. After opening, the system officially starts to evacuate the vacuum. After a period of time, check whether the vacuum inside the system has been evacuated, then close the high and low pressure valves, and then turn off the vacuum pump.

4. When adding refrigerant, disconnect the connection between the yellow tube and the vacuum pump, then connect it to the refrigerant bottle and tighten it.

5. At this time, first open the refrigerant bottle, then open the valve core on the gauge group to exhaust the air in the yellow tube, then turn the refrigerant bottle upside down and put it away at the same time.

6. Open the high and low pressure valves, add refrigerant into the system, and close the high and low pressure valves after the specified amount is reached, and put the refrigerant bottles away.

Is refrigerator refrigerant toxic?

If the body comes into direct contact with refrigerator refrigerant, it is still harmful. But generally speaking, when used as a refrigerant, it is non-toxic and does not cause any harm to the human body. The refrigeration toxins of refrigerators are mainly manifested in the following aspects:

1. It is liquid under high pressure and gaseous under normal pressure. It is colorless, odorless, and has weak irritating and anesthetic effects. When people inhale this gas, they will experience headaches and dizziness, which is actually mild poisoning; in severe cases, they may fall into a coma.

2. At present, the refrigerant for household refrigerators has eliminated the Freon used in old-style refrigerators, and the new isobutane refrigerant is widely used. It does not have the drawback of CFCs that damage the earth's ozone layer, and is a green, environmentally friendly and efficient refrigerant;

3. Its chemical properties are not completely safe and have certain potential dangers. However, since it works in a closed system, it will not cause direct harmful effects. It is flammable and can even explode when mixed with air or encounter open flames. Therefore, if you suspect that there is a leak in the refrigerator, you should immediately open the windows to ventilate the room to dilute the harmful gases in the room and avoid accidents.

How to add refrigerant to the refrigerator? The specific steps for adding refrigerant are as follows. If you are confident, you can add it yourself. If you are really not sure, please find a specialist to do it. Is refrigerator refrigerant toxic? Refrigerant itself is not toxic, but since it is a chemical substance, it has certain potential dangers.
