What is the basic information?

R410A is a new environmentally friendly refrigerant, which is a nearly azeoboiling mixture composed of R32 (difluoromethane) and R125 (pentafluoroethane), with 50% each of the two components.

What are the features?

Environmentally friendly: R410A has an ozone layer destruction potential (ODP) of 0 and will not damage the ozone layer. But it has a higher global warming potential (GWP) of about 2,088, which is 1,725 times that of carbon dioxide and contributes to global warming.

Safety: very low toxicity with the same allowable concentration as R22 of 1000ppm. Non-flammable, the flammable polarity in the air is 0, which belongs to ASHRAE safety level A1 and is harmless to human body 124.

 Physical properties: colorless appearance, non-cloudy, volatile, boiling point -51.6 ° C, freezing point -155 ° C. The water solubility is almost the same as that of R22, and is not soluble with mineral oil or alkylbenzene oil, but with POE (ester lubricating oil) and PVE (ether lubricating oil).

Thermodynamic properties: The working pressure is about 1.6 times that of ordinary R22 air conditioners, and the cooling (heating) efficiency is higher. With near-azeotropy physical properties, the refrigerant temperature slip is less than 0.2 ° C in the whole operation range, and no significant separation occurs in the refrigeration and air conditioning system, that is, the refrigerant composition will not be changed due to leakage.

R410A is a new environmentally friendly refrigerant

What is it used for?

Household air conditioner

This is one of the most important application areas of R410A. Due to its efficient cooling and heating capacity, as well as good environmental performance, it is widely used in various household air conditioning systems, which can quickly adjust the indoor temperature and provide people with a comfortable living environment.

Small and medium-sized commercial air conditioning

Small and Medium unit air conditioners ：In some small commercial places, such as small offices, shops, etc., unit air conditioners with R410A refrigerant can meet their demand for temperature control and have advantages such as easy installation and stable operation.

Home central Air conditioning : More and more households and small commercial users are opting for home central air conditioning systems. R410A refrigerant enables independent temperature control in multiple rooms while ensuring efficient cooling and heating, thus improving comfort.

Multi-online: Multi-online air conditioning systems are widely used in commercial buildings, and R410A refrigerant is able to adapt to the load changes of different indoor units, enabling energy-saving operation, and can connect multiple indoor units through one outdoor unit, saving installation space.

Other Areas

 Mobile air conditioners: Mobile air conditioners with R410A refrigerant are characterized by high mobility and easy installation, and are suitable for some places with temporary or local cooling needs, such as construction sites and outdoor activity venues.

Dehumidifier: In some areas or places with high humidity, dehumidifiers are important equipment to keep the environment dry and comfortable. The application of R410A refrigerant can improve the dehumidification efficiency of the dehumidifier and quickly reduce the air humidity.

Freeze dryers: In industrial production, freeze dryers are used to remove moisture from compressed air to ensure a smooth production process. R410A refrigerant can effectively reduce the temperature of compressed air, allowing moisture to condense and separate out.

Marine refrigeration equipment: R410A refrigerant is also used in refrigeration systems on ships, such as cold storage, air conditioning systems, etc. It can operate stably in the special environment of the ship and meet the living and working needs of the personnel on board.

Industrial refrigeration: In some industrial production processes that require high temperature control, such as food processing, pharmaceutical, chemical industries, R410A refrigerant can be used in industrial refrigeration equipment, such as chillers, cold storages, etc., to ensure product quality and the stability of the production process.

What are the precautions for storage and transportation？

Refrigerant R410A cylinder is a pressurized container. It should be stored away from fire, heat source and direct sunlight. It is usually stored in a cool, dry and ventilated warehouse. Handling should be light loading, light unloading, to prevent cylinder and valve and other accessories damage.

Comparison with R22

Reasons for R410A to replace R22: R22 has a damaging effect on the ozone layer and the use of this refrigerant has been phased out by the international community as required by the Montreal Protocol. R410A does not damage the ozone layer, and has higher refrigeration efficiency, which can improve the performance of air conditioning. It is an ideal substitute for R22.

Differences between the two: R410A has much higher working pressure than R22, about 1.6 times; R410A is compatible with synthetic lubricants such as POE oil, while R22 is compatible with mineral oil; The cooling capacity of R410A is significantly higher than that of R22, making it possible to design smaller and more compact air conditioning units.

R410A belongs to Class 2.2 dangerous goods. There are many precautions when transporting by sea. The following is the specific introduction:

In packaging

Choose the right packaging: R410A is typically packaged in cylinders that meet the relevant pressure resistance and safety standards to ensure that no leakage or rupture occurs during transport.

Packing reinforcement

If there is no outer packing of the cylinder, wooden frame should be made; If there is carton packaging, pay attention to reinforcement, to prevent packaging damage due to collision, friction and so on during transportation.

What should be paid attention to when transporting?

Select appropriate vessels

 Ensure that vessels carrying R410A are qualified and qualified to transport dangerous goods, especially for all-dangerous goods vessels, with a certificate of conformity from the ship control authority.

Temperature control

Although the storage temperature of R410A is generally not particularly strict, it is necessary to avoid exposing the cargo to extreme high or low temperatures during sea transportation in case it affects its properties or causes abnormal cylinder pressure.

Avoid mixing

 R410A should not be mixed with other goods that conflict with each other or may react to prevent danger.
