As it cools the air it brings in, it forces hot air out the back of the air conditioner. After spending countless hours studying how an air conditioner works, I put together all my research and explaining them in laymans terms here. SPONSORS / Collabs:Would you like to partner with Word of Advice TV? Please copy/paste the following text to properly cite this HowStuffWorks.com article: Marshall Brain, Charles W. Bryant & Sara Elliott After the expansion, the temperature of the refrigerant is about 5C, ready to cool the room. Usually, it has to be off for at least 3 minutes before turning on again to prevent it from being damaged. FriedrichGo & FriedrichConnect Wi-Fi Operation Manual. A refrigerant absorbs heat from a room and rejects it outside the house. document.getElementById( "ak_js" ).setAttribute( "value", ( new Date() ).getTime() ); Your email address will not be published. Construction, Types & Working, Difference Between Summer and Winter Air Conditioning System. This air is pulled through one or more filters, where airborne particles such as dust and lint are removedin fact, sophisticated filters may remove microscopic pollutants as well. The coolant flows out of the compartment into the compressor taking the heat with it. A propeller type fan is used to draw air from atmosphere and to circulate through the condenser coil. These components work together to quickly convert the refrigerant from gas to liquid and back again. Its also nice to stand in front of if youre roasting in a hot room. Whilst air conditioners are usually associated with making conditions in a room cooler, the science behind making a room cold using an air conditioner actually involves the transfer of heat from the inside of a building to the outside. This removes moisture out of the air, dropping its relative humidity values. Some of the HFC members are familiar names such as R132a, R410A, and R32. Home Air Guides and some products featured on the site are owned by the same company. Welcome, I hope you can find your solutions here. Air circulates back to the indoor unit of the air conditioner and passes through the chilling evaporator coil. Refrigerant is the working fluid in an air conditioning system. This means that it's increasingly difficult to obtain replacement chemicals and parts for units made before 2010. Window air conditioner is sometimes referred to as room air conditioner as well. SolCool's hybrid solar air conditioner, for example, runs on solar energy, can be . Although important, this is but one of several aspects of air conditioning. If you prefer video, I have one on YouTube which go in-depth into the fundamental of how air conditioners work. It is located at the front end of room air conditioner. A reversing valve (also known as 4-Way-Valve) is used to accomplish this. On July 17th, 1902, Willis Carrier invented the first modern air conditioning system. This article was originally published on aircondlounge.com. Is Air Conditioning Bad for the Environment? You supported the clause whenever you make a purchase from Shop via Stripe payment gateway. If you have a Frigidaire window air conditioner with cooling capacity of 15,000-28,500 Btu or you want a better understanding of how this type of air conditioner is installed, read the installation instructionhere. Some examples of refrigerants include sulfur dioxide, ammonia, methyl chloride, carbon dioxide, and ether. A window air conditioner unit implements a complete air conditioner in a small space. This cooled fresh air isthen mixed With the room air. See below for detailed video on how the thermal expansion valve works. When the temperature in the room begins to rise, the motor kicks in at full throttle again to begin cooling the room back to the desired temperature. The front panel is the one that is seen by the user from inside the room where it is installed and has a user interfaced control be it electronically or mechanically. Activating Cool Mode on a Digital Control Panel: Press POWER. Air conditioners monitor and regulate the air temperature via a thermostat. Here is how they look on the exploded diagram of window AC with heater: Window AC with heater in cooling mode. McDonald Company, the air is not circulated from outside the home. Show more Show more License Creative. Lastly, air conditioners require power and thus, properly sized cables must connect the condenser (outdoor unit) and evaporator (indoor unit) with appropriate conduit for cable protection. It is located in return air path near filter. The fresh air is cooled by evaporator coils, while coming from damper. This low-temperature, low-humidity air is sucked in by the ACs blower, and exhaled at high velocity, passing through a metal duct, and blown out through the ACs front panel. Refrigerant is a general name given to a group of chemicals such as hydrofluorocarbons (HFCs), ammonia, propane, and carbon dioxide. Thermal equilibrium is an instance where there is no net flow of thermal energy between two connected physical systems. At the beginning of this article, we mentioned how the blower pulls in room air and along with it comes dust particles. After the evaporation stage, all liquid refrigerant should turn into gas form, goes back to the compression stage, and the cycle continues. This approach has evolved over the years because it's low-cost, and also because it normally results in reduced noise inside the house (at the expense of increased noise outside the house). This pressure forces the liquid out of the compressor through the hoses in your AC hose assembly, which carry refrigerant through the system. The evaporator does the exact opposite of the condenser. Easy to install, mobility and shifting. The fan of an air conditioner consumes relatively less power, second to the compressor. As you discovered, window AC units use two air cycles to cool down a room and the unit itself. They need to be replaced periodically to maintain their filtrating performance. HFC is the most common type of refrigerant used in residential air conditioners, particularly R410A and the newer one, R32. Fans are used in air conditioners to circulate air through the condenser and evaporator coil. These components work together to quickly convert the refrigerant from gas to liquid and back again. Although the pressure is reduced during condensation, it is still relatively high. Secondly, the split air conditioner cools rooms without any ducting and is a simpler system. Older unit usually are of mechanical control type with rotary knobs to control the temperature and fan speed of the air conditioner. The front panel is the one that is seen by the user from inside the room where it is installed and has a user interfaced control be it electronically or mechanically. The air conditioner is using the vapor-compression refrigeration cycle. The Montreal Protocol requires the phase out of CFC by 1995 and HCFC by 2030. This means that it can cool a larger area space. If you take the cover off of an unplugged window unit, you'll find that it contains: The fans blow air over the coils to improve their ability to dissipate heat (to the outside air) and cold (to the room being cooled). An air conditioner goes through 4 processes; compression, condensation, expansion, and evaporation. When attached together, they blow air. The problem for UK residents is that single hose ACs . Pursuit the truth and learn the fundamental ways to approach the chilled-water system. Some ductless systems can include multiple indoor units connected to one outdoor unit. To learn more about HVAC, purchase and download the HVAC Begin (eBook). Refrigerant is pumped through tubing in the unit, initiating the refrigeration process. The air inside your room, out in the front of the air conditioner where the cooling coil is, thats what we call room air.. Now, the expanded liquid refrigerant begins the evaporation process by absorbing the heat from the room. The indoor unit, typically a furnace or a fan coil, includes the evaporator coil and blower fan (air handler) that circulates air throughout the home. Excessive airflow at the evaporator coil slows down the dehumidification process, resulting in the relative humidity of air not reduced to a comfortable level. Check out my post on why R32 is the best refrigerant for air conditioners. Air that has been conditioned is then discharge to deliver the cool and dehumidified air back to the room. An air conditioner transfers heat energy from a room to the outside of a house, thus cooling the room. The temperature of the contacting surface (evaporator coil) is well below the dew point. For inverter type, one extra signal cable is required for the indoor unit. Thus, insulating the copper pipes is necessary to prevent the losses of energy (or the losses of the coldness) and hence, to prevent the drop of energy-efficiency of the air conditioner. The complete process of air conditioning includes the following processes. This air mixes with the room air to bring down the temperature and humidity level of the room. Fan blades are usually made of plastic due to their low cost and lightweight. Copper tubes are for the refrigerant to flow through while aluminum fins enhance the heat transfer process. If you wish to know more, here are some of my other posts related to dehumidification: Typically, a single-phase power cable connects to the outdoor unit of a residential split air conditioner. Air conditioning units work by removing the warm air from inside your home and pumping it outside, while releasing the cool air back into the room, reducing the temperature. Once its cooled, the refrigerant first enters into the expansion valve, and then the evaporator, or cooling coil. The interior of the unit uses a fan to blow air over the evaporator to cool the room. Artwork: How car aircon works (simplified). Here are the air conditioners frequently asked questions and answers. Another important aspect for how do window air AC units work, is the thermostat. During condensation, moisture in the air will form water droplets and discharged via the drain pipe of an air conditioner. Compressor contributes the most noise and vibration in an air conditioner. The hot air blends with the atmosphere and the fresh atmospheric air gets absorbed and pushed over the condenser. In this section, Ill introduce the 4 major components inside an air conditioner that perform the 4 processes mentioned earlier. To maintain the purity of air inside the room, fresh outdoor air is made to enter into the room through air damper. Air conditioning process obeys the first law and the second law of thermodynamics. Air conditioner refrigerant has become a hot topic due to its effect on the ozone layer of our earth. Filter drier can be found inside the outdoor unit of an air conditioner. The fan blade is usually made of plastic that is designed at a certain angle of attack so that it can push air effectively. In a traditional AC, the compressor switches on and off at regular intervals. Most central heating units are of this type. It is also made up of copper tubing, like condenser coils. Addition of moisture in the air (Humidification) or removal of moisture from the air (Dehumidification) 3. Still, the major parts of an air conditioner manage refrigerant and move air in two directions: indoors and outside: The cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room. It absorbs the heat from the high-temperature medium and exerts it on the high-temperature medium. Window air conditioning system consists of following components: Al the above mentioned components are briefly discussed in the following manner. Cold refrigerant arrives at the indoor unit of an air conditioner. Using the PT chart, we can determine if the pressure of the refrigerant in an air conditioner is within the appropriate range or not. In a ductless system each indoor unit is designed to provide cool air only for the room in which it is installed. Whenever an air conditioner is turned on, the refrigerant goes through these 4 stages: compression, condensation, expansion, and evaporation. It is a medium flow through the refrigeration system and carries the heat in different forms. Now you can set different temperatures in each area depending on your comfort needs. WINDOW AIR CONDITIONER: Working Principle: The refrigerant vapour at high pressure and temperature is supplied by the compressor to the condenser. It controls the humidity of a room as 30 to 65% is permitted while the temperature . Other components in the air conditioner are minor but important to the overall performance of the air conditioner. Therefore, water vapor in the air condenses into liquid water and the relative humidity of the air drops, the air is dehumidified. They are available in two-stage systems and single-stage systems. Cooling Capacity For an air conditioner, the more it can remove heat from the room, the higher will be its cooling capacity. However, not all filters are washable. In a window air conditioner, air filter is located on the air entering side of evaporator coil. The most familiar type of air conditioning is summertime cooling. Packaged systems also offer a variety of options to provide better energy efficiency. This video tells the clear idea about how to work a home air condition. The blower pulls in room air thats hot and full of dust particles and moves it through the air filter, separating out the unwanted particles. Then, there are 4 major components in an air conditioner: compressor, condenser & evaporator coil, fan and expansion valve are responsible for the 4 processes in the refrigeration cycle. We also participate in other affiliate programs which compensate us for referring traffic. Second, the cooling coils temperature is lower than the rooms dew point, causing (you guessed it) dew to form on the cooling coils surface. Hose down the face panel, filter, evaporator, condenser, and drain pan. Relevant post: Air Conditioner Wire Sizing Guide: Chart & Calculation. How Does a Window or Room Air Conditioner Work? And this process will continue to go on until the room temperature stays to the desired level. Particles such as metal chips and specks of dirt can be gathered inside refrigerant copper pipes during installation. So when the air conditioner cools down the temperature of the room to the desired temperature of the room then the compressor of an air conditioner will automatically down. For simplicity, you can view the first law and second law of thermodynamics as the law of conservation of energy and thermal equilibrium respectively. The unit pulls hot air from the room and uses a compressor to turn the hot air into cold air, trapping dirt and debris in the filter. Most residential air conditioners are with a capacity of not more than 2.5HP. Maintain it regularly, and your window air conditioner will provide blissful cooling for years to come. A filter is an extremely convenient and cost-effective solution to maintain the performance of an air conditioner. First of all, at its core, an air conditioner is working based on the laws of thermodynamics. In an air conditioning system, this hot gas is then circulated through a series of tubes, where it dissipates its heat. The pipe running from the evaporator (indoor unit) back to the condenser (outdoor unit) is often called the gas pipe. Thus, the refrigerant gas can be compressed and the system works. An air conditioner uses the refrigeration cycle to perform heat absorption and rejection and therefore, provide cooling. Call Jimmy Brod @ 863-655-5000 for details. It is called a split air conditioner because it has an inside and an outside part. I've been working as a professional in the HVAC industry for more than 7 years, covering from design and installation to commissioning and maintenance. The atmospheric air is already comparatively hot; after absorbing the condensers heat, the temperature rises even higher. Refrigerant circulates between the indoor and outdoor unit to remove heat from a room via the copper pipes. Among the refrigerants, hydrofluorocarbon or HFC is best suited for air conditioners. Refrigerant gas enters the compressor at the outer ring and then, is forced to travel to the inner ring, squeezed and compressed in the process. It does not create any cold energy to cool the room. How to Wire an Air Conditioner for Control - 5 Wires Breakdown of Colors and Terminals | Thermostat Wiring Diagram for AC Unit R Terminal for the Red Wire W Terminal to the White Wire G Terminal to the Green Wire Y Terminal to the Yellow Wire C Terminal to the Blue Wire The lesser it weight, the lesser energy it consumes. Once the room temperature has been achieved, the compressor cuts off. Once in the evaporator, the refrigerant experiences a pressure drop, expands and changes back into a gas. Either permanent or replaceable filters are used. Firstly, the split air conditioner has a larger compressor when compared to the window air conditioning units. Required fields are marked *. Higher efficiency models include multi-speed blower fans. Another important aspect of understanding how do window AC units work is the hot air cycle. airconditioning-systems.com does not sell any personal information. The condenser coil is located at the outdoor unit while the evaporator coil is located at the indoor unit of an air conditioner. This method uses the window vent insert that comes with the portable air conditioner, coupled with a piece of rigid foam or plywood to block the rest of the window. When an air conditioner is turned on for the first time, these particles will be captured by the filter drier. This drawing, the result of Willis Carriers groundbreaking design, was submitted to Sackett & Wilhelms on July 17, 1902 and provided the basis for the invention that would change the world, the first modern air conditioning system. The fan from the indoor unit pulls hot air from inside the house through return air ducts. The blower fan, on the other hand, has a speed that you can set. The hot side contains the compressor, condenser and another fan to vent hot air coming off the compressed refrigerant to the outdoors. The refrigerant in an air conditioner goes through 4 processes which are compression, condensation, expansion, and evaporation. Then the refrigerant travels back indoors and enters the evaporator coil. Proper sizing and installation are key elements in determining air conditioner efficiency. Window air conditioning system does not require ducts for free delivery of conditioned air intoroom to be cooled. Even if your air conditioner is only 10 years old, you may save 20% to 40% of your cooling energy costs by replacing it with a newer, more efficient model. A finned-tube heat exchanger is made of copper tubes and aluminum fins. Once the filter gathered a significant amount of dust, it can be washed and reuse. Portable air conditioner recommended by 6 reputable reviewers. Typically, youll see three black tank-alike components inside an AC outdoor unit. Still, the major parts of an air conditioner manage refrigerant and move air in two directions: indoors and outside: Evaporator - Receives the liquid refrigerant Condenser - Facilitates heat transfer Expansion valve - regulates refrigerant flow into the evaporator Compressor - A pump that pressurizes refrigerant There are many types of refrigeration cycles. With my experience, I want to help people solve their HVAC problems. In another word, copper and aluminum are very good at conducting heat. Compression of refrigerant produces heat. During this stage, the liquid refrigerant expands rapidly causing a huge drop in pressure and temperature. However, without a filter, dust will quickly gather at the condenser and evaporator coil, blocking air from passing through the coils, causing incomplete condensation and evaporation, affecting the performance and reducing the lifespan of an air conditioner. Are you wondering if your current system is still under warranty. Working, Construction & Advantages. 2022, 2021, 2020. The air filter which is mounted in front of the evaporator acts as a filter to keep the cooling coil clean to obtain good heat-transfer from the coil.
