In many ways air conditioning and refrigeration systems are very similar. Both use specially designed chemicals, the physical effects of the compression and expansion of gases, and the conversion of gas to liquid to reduce the temperature of air. The varying uses of these systems, however, mean refrigeration and air conditioning systems have a handful of key differences in the design and operation. A major difference between refrigeration and air conditioning is the point of supply for the gases. Refrigeration systems have gas installed in a series of tubes. In old refrigerators, this gas was chloro-flouro-carbon, or CFC, but this has harmful effects on people, so refrigerators not contain HFC-134a. HFC-134a is the sole gas used as a coolant in refrigeration systems. Air conditioning systems use built-in chemicals, but also air from the room or rooms being heated. Gases built into air conditioning units cool air that circulates through the unit; the unit then redistributes the cooled air through the room. Air conditioners have circulation systems designed to project cool air away from the units while refrigeration units have circulation systems designed to retain coolant in a confined space. Refrigeration systems circulate cool liquids and gases through a series of tubes and vents. Cool air from within a refrigerator is sucked into a compressor that recycles the gas through the tubes. Air conditioners, while also employing tubes in the coolant system, have fans for the dis...

• • • • • • I have an older refrigerator model and recently I noticed that my refrigerator isn’t performing as well as it did when I got it. So the first thing I thought was that there might be a problem with the refrigerator gas. It turns out my guess was correct. The specialist told me that the gas needed to be replaced And that got me wondering which gas is used in my refrigerator?. The answer to that question was not that simple. It turns out there are a lot of gases that you can use for your refrigerator. It all depends on the model of your fridge really. To summarize, older models typically before the 90s used CFCs or chlorofluorocarbons. These gasses were harmful to the environment and were soon replaced by HCFCs which were surely better than the previous generation but still polluted the environment. In the early 2000s, another revolutionary advancement was made with the invention of HFCs. These days refrigerators are starting to use hydrocarbons or simply HCs which are really environmentally friendly and greatly reduce the pollutants released into the environment . So let’s go over the types of refrigerant used in refrigerators these days, how they evolved and which gases are used in what refrigerators. Refrigerants: the problems and the solution: To find out more about refrigerant types you can check this video, this really helped me during my research. It does a great job of showcasing the issues we’re currently facing and what we can do to reduce them. You can ...

• Generator - creates ammonia gas • Separator - separates the ammonia gas from water • Condenser - where hot ammonia gas is cooled and condensed to create liquid ammonia • Evaporator - where liquid ammonia converts to a gas to create cold temperatures inside the refrigerator • Absorber - absorbs the ammonia gas in water It works like this: • Heat is applied to the ammonia and water solution in the generator. (The heat comes from burning gas, propane or kerosene.) • As the mixture reaches the boiling point of ammonia, it flows into the separator. • Ammonia gas flows upward into the condenser, dissipates heat and converts back to a liquid. • The liquid ammonia makes its way to the evaporator where it mixes with hydrogen gas and evaporates, producing cold temperatures inside the refrigerator's cold box. • The ammonia and hydrogen gases flow to the absorber where the water collected in the separator in step No. 2 mixes with the ammonia and hydrogen gases. • The ammonia forms a solution with the water and releases the hydrogen gas, which flows back to the evaporator. • The ammonia-and-water solution flows toward the generator to repeat the cycle. A Heated Refrigerator? You may not realize it, but modern refrigerators don't only cool things down, they keep things from getting too cold. Yes, you guessed it: refrigerators have onboard heaters. They're low-wattage, but refrigerator heaters are very convenient and effective at doing everything from heating the evaporator coils to me...

If the compressor is the heart of the refrigerator, then its refrigerant gas (AKA Freon) is its blood. These gases facilitate the heat transfer process that fridges use to create a cold environment for our food. In the Philippine refrigerator market, there are two kinds of refrigerants in use: R-600a and R-134a. While these two gases have the same function, they have different characteristics that make one better than the other in some aspects. To briefly put it: R-600a (Isobutane) has less impact on the environment and is generally more efficient vs. the R-134a (Norflurane) gas. However, one of the drawbacks of the R-600a gas is that it is flammable and it can cause minor health concerns when it escapes from the refrigerator. In this article, I will give you a brief overview of these refrigerants, and I will also give you a rationale on the R-600a vs R-134a debate. • • • • • • • As the liquid form of the refrigerant evaporates, it absorbs the heat from its surroundings, and thus producing a cool environment. Now that the refrigerant has turned to a gas, it needs to be condensed back into its liquid form to start the process again. The catch-all term for these refrigerant gases is “Freon”. Freon is actually a brand name of the chemical Dichlorodifluoromethane R-12, which was the most commonly used refrigerant gas back in the day. Since Freon is a CFC (chlorofluorocarbons), it has been phased out in lieu of more environment-friendly refrigerants because of its capability to...

Table of Contents • • • • • • Which gas is used for refrigerator refrigeration? The ammonia is used in the refrigerator to cool the water. Ammonia is composed of one atom of nitrogen and three atoms of hydrogen. Sulfur dioxide and non-halogenated hydrocarbons are some of the common refrigerants used. Which gas is used in refrigerator formula? A refrigerator contains an electrically-powered compressor that does work on Freon gas. Coils outside the refrigerator allow Freon to release heat when it condenses, and coils inside the refrigerator allow Freon to absorb heat as it vaporizes. READ ALSO: What do PhD students do after graduation? How many types of refrigerant gas are there? The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming…. Refrigerant Global Warming Potential Ozone Depletion Potential R-22 1810 Medium R-410A 2088 Zero R-32 675 Zero R-134A 1430 Zero Is fridge gas toxic? Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it can cut off vital oxygen to your cells and lungs. Limited exposure — for example, a spill on your skin or breathing near an open container — is only mildly harmful. However, you should try to avoid all contact with these types of chemicals. Which gas is used for cooling? Many industrial production processes require rapid cooling and freezing capabilities. Liquid nitrogen (LIN) and carbon diox...

Refrigerant Gases & How They’re Used to Keep Things Cool The ability to make our homes, cars, foods, cool has absolutely transformed the world we live in. We design our homes differently because of our ability to cool them, we don’t need to rely upon a cool breeze. We live in places we wouldn’t have otherwise like Florida and Arizona. We can get our food from any farm in the world instead of just the ones in our neighborhood. We can keep our food safe to eat for years without the time involved in salting meats and canning vegetables. And in the world of industry, the production of electricity, medicines, food and beverages—just to name a few—absolutely depends upon their ability to cool processes, products and spaces. What is Refrigeration? Refrigeration is the artificial removal of heat resulting in less heat. Cold is not energy like heat is; it’s a term that refers to a lack of heat in an object or area. When we try to cool our homes or cars or metal boxes that hold food, we are simply trying to remove the unwanted heat and transfer it somewhere else. This is done through the use of refrigerants which absorb the heat. Liquid expanding into a gas extracts heat from that which surrounds it. When you wet your finger, it immediately begins to feel cooler because the liquid is quickly evaporating, and through this process, it is extracting heat from your skin. Refrigerants The gases that help us with moving heat out are these refrigerants and they are pumped through a closed ...

The time has come! The European F-Gas regulation prohibited the use of HFC refrigerant gases containing PCA ≥ 2500 in new installations on 1 January 2020. Moreover, refrigerants containing GWP ≥ 150 will be prohibited from 2022 onwards; this has revolutionised the industrial refrigeration sector, forcing it to use alternative refrigerants. Below are the most commonly used refrigerant gases in commercial and industrial applications nowadays, classified by sector and units in which they are used, applicable regulations, whether they are harmful to the ozone layer or not and whether they mitigate the greenhouse effect or not. • 1 What refrigerant gases have been used in refrigeration applications until now? • 2 What are the latest trends in this regard? • 3 Most commonly used refrigerant gases nowadays • 4 What are the applicable regulations? • 5 Our goal What refrigerant gases have been used in refrigeration applications until now? Over the past few decades, R404A has been the refrigerant par excellence in commercial and industrial refrigeration applications, due to its properties, making it the perfect refrigerant for low, medium and even high-temperature applications. After the entry into force of the fluorinated gas tax in Spain and with the threats of the imminent prohibition of using R404A refrigerant in 2020 by the European F-Gas regulation, the different gas manufacturers and distributors have launched direct replacements of R404A. Moreover, the use of HFC gases (hydr...
