How does air conditioning and refrigeration work? I'll understand after reading it

Air conditioning and refrigeration are usually compounds that exist in fluid or gaseous form. It easily absorbs heat from the environment, and when combined with other components such as compressors and evaporators, it can provide refrigeration or air conditioning. If you have heard about R22 refrigerant and the phased-out R410A refrigerant, you may particularly want to know more about how refrigerant works and its role in cooling houses.

How does air conditioning refrigerant work? Without refrigerant, there is no air conditioning, refrigeration or freezing technology. The air conditioner contains the refrigerant in the copper coil. When the refrigerant absorbs heat from the indoor air, it changes from a low-pressure gas to a high-pressure liquid. The air conditioning component sends the refrigerant outside, and the fan blows hot air through the coil and discharges it to the outside. Then the air-conditioning refrigerant cools down and changes back to low-pressure gas. Another fan located in the home blows air through the cooling coils to distribute the generated cold air throughout the building. Then the cycle repeats. Advantages: Noise reduction and noise reduction, using aerospace ESQ ultra-quiet technology, flexible upgrade of the air duct, reducing operating noise, reducing noise to 22 decibels, increasing fan efficiency by 10%, and effectively reducing noise by 3.2 decibels;

Types of air-conditioning refrigerants The most common refrigerants used in air-conditioning for many years include: Chlorofluorocarbons (CFCs), including R12. This is known to contribute to the greenhouse gas effect. The production of new shares ceased in 1994. Chlorofluorocarbons (HCFCs), including R22. Compared with R12, the damage to ozone is slightly smaller, but the EPA still requires the phasing out according to the 2010 Clean Air Act. R22 will be completely phased out in 2020. Hydrofluorocarbons (HFCs), including r410a and R134. The mixture does not contain chlorine, which is safer for the environment and is now used instead of R22. Air conditioners running on R410A are more efficient, have better air quality, higher comfort, and higher reliability.

About the use of refrigerants in air conditioners Although R410A is an HFC, which means it is more suitable for the environment than other types of air conditioner refrigerants, it is not 100% safe. This fact prompted the US Environmental Protection Agency to formulate some rules on refrigerant handling and disposal: It is forbidden to intentionally discharge refrigerant. Low-loss accessories must be used to limit the amount of refrigerant released when purging, connecting or disconnecting the air conditioner. Technicians must do their best to safely recapture, recover and dispose of refrigerant. Air conditioners and other appliances that use refrigerants must be disposed of in accordance with EPA's disposal rules. The refrigerant leak must be repaired within 30 days. Only licensed air-conditioning companies and technicians can purchase refrigerants.

Additionally, Hangzhou E cool refrigeration Co.,Ltd has a few new features planned to roll out in the app to provide more convenience, comfort and options to our clients.

Hangzhou E cool refrigeration Co.,Ltd looks forward for the meeting and the association with your esteemed company.

air conditioner capacitor continued to evolve to having strong manufacturers develop huge marketers and people came to value their opinions about what to buy.

The engineers and developers of Hangzhou E cool refrigeration Co.,Ltd are the best in their own professional way and we guarantee to provide related service to our dear customers.

If Hangzhou E cool refrigeration Co.,Ltd added selling plans, offered more refrigerant gas, and increased service regions, it would suit the needs of more users.
