How is the environmental performance of R408A refrigerant?

The environmental performance of R408A refrigerant is related to the business of cooling and heating, and the state of heaven and earth, which cannot be ignored. This agent is composed of a variety of chemicals, including R125, R143a and R22, each accounting for a fixed proportion.
When it comes to ozone destruction potential (ODP), the ODP of R408A is 0.016, which is lower than that of some refrigerants in the past, but it is still not perfect. In the past, the powerful ozone-destroying agents, such as R11, R12, have an ODP as high as 1.0. In comparison, the damage degree of R408A has been reduced, but it still has the risk of destroying ozone, and the protection of the ozone layer is poor, which is not a long-term choice.
As for the global warming potential (GWP), the GWP of R408A is quite high, reaching 3550. At this time, the world is pushing for low-carbon emission reduction to slow down the speed of global warming. High-GWP refrigerants are discharged into the atmosphere, which will exacerbate the greenhouse effect and have a significant impact on the earth's temperature change.
Furthermore, R408A contains R22, which is not friendly to the environment. Although there may be advantages in terms of cooling efficiency, in the long run, due to the characteristics of ODP and GWP, they are gradually being replaced by better environmentally friendly refrigerants, such as R32, R290, etc. The latter two have either zero ODP or very low GWP, which is more in line with the trend of environmental protection.
Therefore, R408A refrigerant lacks its environmental protection performance. Under today's environmental protection trend, it is necessary to find a better substitute to protect the ecology of heaven and earth and keep the cold and warm industry for a long time.

What are the pressure and temperature characteristics of R408A refrigerant?

R408A refrigerant is a mixed refrigerant. Its pressure and temperature characteristics are crucial and affect the performance and operation of the refrigeration system.
The pressure and temperature characteristics of this refrigerant are different. At a specific temperature, the pressure value can quite show its characteristics. When the temperature increases, the pressure also increases, and the two are positively correlated. Due to the increase in temperature, the thermal movement of molecules intensifies, and the collision with the container wall is more frequent and violent, causing the pressure to rise.
If the evaporator is used as an example, in a low temperature environment, R408A evaporates and absorbs heat, and the pressure is low. In the condenser, the refrigerant condenses and exotherms at high temperature, and the pressure increases significantly. This change in pressure and temperature is just like the vein of the cycle, which maintains the operation of the refrigeration system.
Furthermore, under different working conditions, the pressure and temperature characteristics of R408A also have different performances. In the refrigeration conditions of air conditioning and cold storage, the pressure is also different because of the different temperatures required. Air conditioning refrigeration needs to maintain a comfortable indoor temperature, and the pressure and temperature range is suitable for the living environment; cold storage refrigeration requires extremely low temperatures, and the pressure and temperature are adjusted accordingly.
The precise regulation of its pressure and temperature characteristics is the cornerstone of the efficient and stable operation of the refrigeration system. Those who operate the refrigeration system must be well aware of this characteristic in order to respond to different needs, so that the system can exert the best performance and achieve the purpose of refrigeration.

What are the precautions for using R408A refrigerant during use?

R408A refrigerant is also used in refrigeration. When it is used, many matters must be observed.
The first thing to bear the brunt is safety. R408A contains fluoride. If it leaks into the atmosphere, it will damage the ozone layer, and if it encounters an open fire or hot topic, it may generate harmful gases. Therefore, during operation, it is necessary to beware of fire sources and ensure that the work place is well ventilated. If it leaks accidentally, leave the scene quickly and call a professional to take care of it.
Furthermore, the control of temperature and pressure. The characteristics of R408A make the pressure and temperature in the refrigeration system fixed. During operation, it is necessary to strictly monitor the system parameters, so as not to exceed the pressure and temperature limit, so as not to damage the equipment and prevent accidents.
There is another compatibility section. This refrigerant must be compatible with other components in the system, such as lubricating oil, sealing materials, etc. Otherwise, the material will be invaded, causing leakage, and affecting the effectiveness of refrigeration. Therefore, when selecting materials, it is necessary to review their compatibility with R408A.
Filling process should not be taken lightly. It must be filled accurately according to specifications. Filling too much or too little will damage the operation of the refrigeration system. Excessive will increase the system load and damage the equipment; too little will cause insufficient cooling.
At the end of the day, when storing, it should be placed in a cool, dry and ventilated place, protected from direct sunlight and heat sources. And the container must be completely solid to prevent leakage. Therefore, Fangbao R408A refrigerant is safe and efficient.
