The Refrigerant in My Air Conditioner: What Is It, Anyway?
Ever wondered how your air conditioner cools your home? The science behind an air-conditioned home is in the refrigerant. But, what is refrigerant in particular? How does it work in producing a cool temperature in your space?
Let us find out the answer to each question as we go through this post.
The Basics of Refrigerant
Air conditioning units require a chemical called refrigerant to serve its purpose. The refrigerant is a chemical blend in liquid form which turns into gas then releases in the atmosphere as heat. The cycle happens repeatedly and vice versa.
Over time, the types of refrigerant had changed drastically from combustible ones like sulfur dioxide to non-toxic chemical mixtures including pentafluoroethane (R-410A) used in residential A/C units. Working in two phases (liquid and gaseous), the refrigerant absorbs heat and cools it down inside your home then exhaust it outside. Because it can easily shift from one phase to another, your air conditioner does not have to work harder to complete the evaporation and condensation process.
The Role of Refrigerant in Your Air Conditioner
The refrigerant starts working in the compressor where the high-pressure gas has to reach 150 degrees Fahrenheit. The gas moves into the outdoor condenser coil where it combines with the warm air for condensation. After the condensation is completed, the heat is released from the refrigerant heading to the indoor coil. From 150 degrees Fahrenheit, the temperature of the gaseous refrigerant is lowered to 100 degrees Fahrenheit. As the gas moves closer to its destination, its temperature and pressure continuously drop until it changes into a liquid of about 20 degrees Fahrenheit.
Passing over the evaporator coil, the cold refrigerant attracts the outdoor warm air to undergo evaporation. The process warms the refrigerant and lowers the indoor temperature. At the end of the cycle, the refrigerant reaches 50 degrees Fahrenheit then goes back to the compressor to repeat the process.
Without leaks or issues in the duct system and other parts of the air conditioner, the refrigerant retains its set level. A decrease in the level of refrigerant can pose risks in the compressor and your A/C unit as a whole.
