how does ac refrigerant work

An air conditioner works using a thermodynamic cycle called the refrigeration cycle. With a gas furnace you have the heat from the flame blowing into your home. If you’re interested in air conditioning units and the like, why not consider a career in HVAC service? These common refrigerants all have extremely low boiling points compared to water. How does air conditioning work? You may not be using it often now, but in just a few weeks, it will likely see daily use and more. The greater the temperature difference, the easier the heat transfer will be. They’ve also made helpful tools like their refrigerant retrofit guide, Low-GWP Tool, and Coolselector 2 app available for free on their website. The compressor constricts the refrigerant vapor, raising its pressure, and pushes it into the coils on the outside of the refrigerator. But how does it manage that? The chemical reacts by boiling through an endothermic reaction. It is mandatory to procure user consent prior to running these cookies on your website. Thanks for sharing the informative post. It doesn’t matter what type of refrigeration system you use, from the refrigerator in your home, a small split a/c unit all the way up to an industrial chiller. As the name suggests, it “compresses” the refrigerant so that it turns from a gaseous state into a liquid state. These cookies will be stored in your browser only with your consent. After the condenser, the refrigerant goes through the expansion valve, where it … As the air blows across the tubes, it removes heat from the refrigerant. This needs to occur again and again, continuously without fail. You also have the option to opt-out of these cookies. The refrigerant will leave the compressor and travel through the condenser at a temperature around 30 degrees higher than ambient outdoor air temperature. The refrigeration cycle basically involves the movement of refrigerant from one place to the next and in different forms with the ultimate goal of pulling down temperatures whether in a cabinet, counter or even cold room format. Necessary cookies are absolutely essential for the website to function properly. Remember we looked earlier at the low boiling point of refrigerants, so room temperature air is enough to boil it into a vapour. The refrigerant travels back to the evaporator where the process begins again. The molecules are all constantly bouncing around and compressing them into a smaller space causes them to collide more often, as they collide they convert their kinetic energy into heat. While the fans are cooling the gas, the pressure pulls the molecules tighter together, and the refrigerant condenses again into a liquid. You could salt foods, and in winter, you could bury food in a snow drift and hope the critters didn't find it. For example, we’re used to water boiling at around 100°c (212°F) that’s because most of us live near sea level so the air around us is compressed by all the weight of the atmosphere above us. This is also known as hidden heat. The screw compressor competes with lar… Air conditioners use refrigeration to cool the air indoors through a physical law: when a liquid converts to a gas, it absorbs heat. EXPLANATION OF HOW IT WORKS/ IS USED: Refrigerant flows through the compressor, which raises the pressure of the refrigerant. First, thanks for a great explanation of refrigerants. This allows it to evaporate into a vapour with very little thermal energy applied which means the refrigerant can extract heat more rapidly. Howard Air – How Does an Air Conditioner Work? The temperature drops to a more manageable level, causing the piping to shift from burning hot to very warm. We also use third-party cookies that help us analyze and understand how you use this website. As the cool refrigerant gas flows through the chiller cabinet, it absorbs the heat from the food items inside the fridge.
