The main function of the refrigeration cycle is to absorb heat from the indoor air and dissipate it to the outside. These components come in several different designs. The most popular configurations include fixed orifices, thermostatic expansion valves (TXV) or thermal expansion valves (pictured above) and the more advanced electronic expansion valves (EVE). However, regardless of the configuration, the function of a system's expansion device is the same: creating a pressure drop after the refrigerant leaves the condenser.
This pressure drop will cause part of that refrigerant to boil quickly, creating a two-phase mixture. The evaporator is located on the cold side of the air conditioner. Its main function is to receive liquid refrigerant and convert it into gas, which then cools and dehumidifies the air. The gas absorbs all the heat from the air and carries it to the condenser.
There are four main components of an air conditioning system. They are the evaporator, condenser, compressor and expansion valve. Each of these air conditioner components works in sync with each other and has a specific function to fulfill: keeping the air conditioner running like a well-oiled machine. For example, residential HVAC chillers typically use ammonia as a coolant and water as an absorbent.
Water is found in a component called an absorber, where it sucks in ammonia from the low pressure side of the system and removes heat while absorbing it. A pump sends the water and ammonia solution to a generator, which boils it and separates the ammonia from the water before sending it to the high-pressure side. This is the heat that the condenser expels during the process by changing the refrigerant from hot steam to hot liquid. The condenser, or condenser coil, is one of two types of heat exchangers used in a basic refrigeration circuit.
Air conditioners have been around since 1902 and have become a necessity in almost everyone's mind, especially if you live in a place like Houston. You can keep the most important air conditioning component in good condition by frequently checking for refrigerant leaks, preventing 26% contamination from dirt, keeping condenser coils clean and keeping the air conditioner well-oiled. In this blog, we'll look at these four components and explain the important role they play in the air conditioning process to help you better understand what might be failing in your system. With the hot summer just around the corner, the last thing you want to experience is a problem with your air conditioning system.
This causes the refrigerant to condense back to a liquid form that is quite cold, which is then sent back to the start of the process in the evaporator coil. Once the refrigerant is a cold mixture of liquid and gas (vapor), it starts to move through the evaporator. In addition to the absorption process, heat is also used to move the refrigerant throughout the system. These condensers are used for freon cooling units, which are normally applied in areas where there is not enough water supply.
This is why the air that leaves the outdoor unit often feels extremely warm, even on very hot days. As HVAC compresses gaseous and cold refrigerant, it transforms into very hot, high-pressure vapor. Usually, the refrigerant will be extremely cold when it enters the evaporator coil, but it will be warmer at room temperature when it comes out. There are some common problems with air conditioner components that can cause the air conditioner to operate below optimal levels or stop working altogether.
