Recently, the United States announced that it will include R450A refrigerant in new refrigerant replacement. It is reported that R450A refrigerant was developed by Honeywell. The refrigerant is an incombustible mixture. The group distribution ratio is 42% of R134a and 58% of HFO-1234ze, ODP value is zero, GWP value is approximately It is 601. It is understood that the new refrigerant R450A is considered as an ideal alternative and can be widely applied to products, including retail food...
After entering the midsummer, some citizens are accustomed to seeing the refrigerator as a food safe, and almost all their dishes and drinks are stored in the refrigerator. As everyone knows, foods are kept in the refrigerator for too long and all kinds of bacteria, especially E. coli, will breed in a cool and cold environment. When a friend who eats cold food eats immediately after taking out the food from the refrigerator, the bacteria will invade the gastrointestinal tract and cause...
Shenzhen Dongyue Water Chiller Factory teaches you to judge the five phenomena of refrigerant overcharge of chiller refrigeration system: refrigerant, also known as refrigerant, is commonly called snow in some areas in the south. It is a working substance that continuously circulates in a chiller refrigeration system and changes its state to realize refrigeration. The refrigerant absorbs the heat of the cooled medium (water or air, etc.) in the evaporator to vaporize, and the heat is...
[China Aluminum Network] The leakage of refrigerant in cold storage is a headache for many refrigeration engineering companies, distributors, and customers. The leakage of refrigerant and the aluminum row are inextricably linked. Many details of the aluminum row will directly affect whether the refrigerant will cause leakage problems. The specific details include: welding process, surface treatment process, tube wall Thickness, material selection, etc. Today, the reporter will share with you...

Please allow me to teach you how to judge if a water chiller needs to be filled with refrigerant. The common methods include: 1.The observation method It indicates the proper amount of refrigerant when moisture condenses on the high-pressure pipe that touches icy and moisture condenses as well on the low pressure pipe, which touches cool with the temperature around 3℃ higher than that of the high-pressure pipe. It indicates that the amount of refrigerant is insufficient and refrigerant filling...
In the hot summer, people naturally think of air conditioners that bring in cool breezes and comfortable surroundings. Drinking a refreshing drink from the refrigerator can also be refreshing. All this is a great gospel of refrigeration technology brought to mankind. In the rapid development of modern refrigeration technology, the invention and development of refrigerants play a crucial role. There are currently about 30 kinds of industrial refrigerants. Commonly used Freon and ammonia...
NIO becomes first automaker in China to use Honeywell's R1234yf refrigerant with ultra-low global warming potential Honeywell's HFO-1234yf refrigerant has a GWP of less than 1, a 99.9% reduction compared to HFC refrigerants currently used in the Chinese market. NIO becomes first automaker in China to use Honeywell's R1234yf refrigerants with ultra-low global warming potential. (Image credit: CnEV) At a time when China's new energy vehicle (NEV) industry is growing rapidly, automakers are making...
At present, China's inverter air conditioners, air conditioners exported to Europe and Australia have used refrigerant R410A to replace R22, and this part of the air conditioning output is about 30% of the total air-conditioning output of the country. The larger alternative market is in the country. At present, major air-conditioning companies in China have already fought on new refrigerants to advance the battle for new environmental refrigerants. It is reported that, due to the replacement of...
From January 1, 2017, all new vehicles produced and sold in Europe are prohibited from using GWP >150 refrigerant. It can be seen that the phasing out of R134a (GWP=1300), which is widely used as a refrigerant for automotive air conditioners, will become an inevitable trend. DuPont and Honeywell's fourth-generation refrigerants R1234yf and R1234ze are considered to be the next-generation environmentally friendly refrigerants to replace R134a, so R1234yf will be used first in automotive air...
