Heating and cooling systems are based on the idea that “liquids absorb heat when they evaporate.” When alcohol is applied to the skin, for example, it cools the skin. Because the alcohol evaporates, it takes in heat from the surrounding environment. The transformation of a liquid into a gas requires, as is well-known, the application of heat. Cooling occurs as a result of the liquid absorbing heat from the surrounding area.
Car Air conditioners and refrigerators use this principle as a foundation. There is no air conditioning system without a compressor. The refrigerant is pressurized or compressed, resulting in its transformation from a gaseous state into a liquid. To get to the compressor, the compressed liquid refrigerant has to travel through the condenser’s tubes. This is where the liquid refrigerant comes into contact with the outside air. The high-temperature liquid in the condenser creates a temperature differential with the surrounding air. The liquid then radiates the heat into the atmosphere. Thereafter, it is sent to the receiver, dryer, or accumulator, depending on the model.
Let’s Look at The Processes Involved
Using a desiccant, which removes moisture from air and refrigerant, the system is able to maintain a cooler temperature. The cooled liquid refrigerant enters the expansion valve or orifice tube. Reduced overall fluid pressure enables the fluid to reach the condenser (another component of AC). The evaporator will then receive the refrigerant. The evaporator’s core will be filled with the car’s exhaust fumes, which will be drawn into the device.
A colder refrigerant temperature previously allowed the machine to cool the air by converting heat from outside into the cold. Cool air is forced through vents near the passenger seat by fans to keep the interior of the car comfortable. Using this method, you’ll be able to breathe clean, dry air. In addition, the condensate is collected and drained during this procedure.
Liquid refrigerant in an air conditioning system returns to a gaseous state after it has been used. Before returning to the compressor, this hot, low-pressure gaseous refrigerant circulates once more. When the new cycle begins, you are greeted by cool, dry, and fresh air.
