What are the common refrigerants?

Refrigerant, also known as refrigerant, is a working fluid used in refrigeration and air-conditioning systems to transfer heat energy and produce a freezing effect. When talking about refrigerant, most people think of air conditioners first. Indeed, in terms of daily life, air conditioners are installed in almost every household, and the frequency of application is quite high. However, today we are not talking about air conditioners, but air energy heat pumps that have similar principles to air conditioners.


Air conditioners are mainly used for refrigeration, and air energy heat pumps are mainly used for heating. The heating principle of the heat pump is actually the inverse principle of air conditioning and refrigeration, which absorbs heat energy in the air through refrigerant. Therefore, it is not unreasonable to say that the refrigerant plays a key role in the heating of air energy. And what kinds of refrigerants are common in air? Let's take everyone to get to know them today and walk into refrigerants:


1. R22 refrigerant


R22 is a single refrigerant (cold inside), its scientific name is difluorochloromethane, and its boiling point is about -41°C. This kind of refrigerant is colorless and odorless, and is widely used in air conditioning systems, especially in split air conditioning and air conditioning systems, which can be said to be seen everywhere. However, it has a big shortcoming, that is, it is actually a member of the Freon family, and when discharged into the air, it may damage the ozone layer and cause environmental problems.


2. R410A refrigerant


R410A refrigerant is an environmentally friendly refrigerant developed by scientists for the deteriorating environment. It is similar to R134A, colorless, volatile and non-flammable. The composition contains R32 and R125 refrigerants, the boiling point is about -51℃, does not contain chloride ions, and does not destroy the ozone layer. The water solubility is indistinguishable from R22, but the cooling capacity has been significantly improved. Now it is also a new type of environmentally friendly refrigerant common in the air energy industry!


3. R134A refrigerant



The composition of R134A refrigerant is different from that of other refrigerants. It does not contain chloride ions, is not toxic, is not combustible in the air, and does not cause damage to the ozone layer. It looks good, but its boiling point is relatively low, only -26.5°C, which means that if it is used in a heat pump, once the ambient temperature drops, the amount of vaporization of this refrigerant will be greatly reduced. As a result, the heating efficiency of the heat pump decreases. Therefore, this refrigerant is not as widely used as R22, and is generally used in indoor or high-temperature heat pumps.


4. R290 refrigerant



R29 refrigerant is another new environmentally friendly refrigerant, colorless, slightly soluble in water, and free of ozone. If it is mixed with air, there is a certain probability of explosion. If it encounters an open flame, it is easy to cause accidents. At present, the industry is accustomed to use high-purity R290 refrigerant as the temperature sensing working fluid.

Sawfish, an Unsinkable, Lightweight, Foam Kayak (23 Lbs). Free DIY Kayak Plans, the Hardware Store Boat

Do you really want a kayak? Want one so bad you can taste it, but can't afford one, or think you don't have the skills to build one? Then I have a few questions for you. Can you cut a crusty bagel with a knife, stack blocks, stick a sandwich together with mayo, skewer meat and veggies for kabobs, grate cheese, cut thin fabric with scissors, stretch wrinkles out of bed sheets, and roll paint onto a wall? Then you can build this boat! Unlike most boat seal plans that require you to do a whole bunch of reading and learning, require you to buy or own lots of tools and learn what seems like a whole new language devoted to boat building. I designed this boat, and wrote this I'ble, to be as simple as possible. You don't need any boat building books, or much in the way of tools. You can find everything you need to build this boat at hardware stores, the internet, and discount stores. When you are done, you will be a real boat builder, and have an excellent boat to show for it

Shaken, Stirred and Elementary: ‘Sherlock Holmes’ and ‘Thunderball’

Image
Created by Arthur Conan Doyle, the detective Sherlock Holmes belongs to us all. As noted by the historian Michael Saler in "As If," his account of literary imaginary worlds, the great detective was modern fiction's "first virtual reality character" — given that part of his readership chose to believe that he was an actual person. The 1916 movie "Sherlock Holmes" (newly restored and released by Flicker Alley in a dual Blu-ray/DVD edition) grounds that character's virtual reality in a corporeal presence, namely that of the tall, craggy American actor William Gillette (1853-1937). Mr. Gillette, the son of a United States senator from Connecticut, was Holmes's contemporary. It was during the hiatus between the fictional character's apparent demise in a struggle with Professor Moriarty and his return to life by popular demand that Mr. Gillette metal got the opportunity to take the title role in a revision of Conan Doyle's unproduced Holmes

G-Technology is a relatively new and unknown name in the storage industry, though it's beenaround for a while in international markets. It had its beginnings as a specialised storage vendor targeting creative professionals, particularly those who use Apple's Mac ecosystem. The company was acquired by Hitachi Global Storage Technologies (HGST), which itself is now owned and operated by Western Digital. WD is a brand we are much more familiar with, and thanks to its global reach, we now have the G-Technology product lineup here in India. WD still intends to target creative professionals, and these products will live alongside a few similar offerings from HGST, SanDisk, and WD itself.The G-Technology range is pretty vast, encompassing enterprise-class storage servers, modular desktop RAID boxes, and equipment for demanding video machine and photo production environments, even outdoors. Use cases include editing high-resolution video live in the field, managing footage from mult
