We will compress a vapor refrigerant. inside the system to obtain therefrigeration or cooling. If we are going to compress vapor in this system of refrigeration, then obviously we will need a compressor for this job, so the process of compressing the vapor refrigerant inside the system using a compressor to obtain refrigeration or cooling is called vapor compression. refrigeration system, now let's look into the major parts and components and basic working procedures for the vapor compression refrigeration system, so here We have a compressor, and after that, there is a condenser, then there is an expansion. valve, our throttle valve, or we can simply call it a valve, and finally there is an evaporator, so these four major components are connected together to construct the vapor compression refrigeration system allThese components are connected together.using these connecting pipes Thus, a closed-loop system is formed, and the refrigerant for this vapor compression refrigeration system will flow through all these components and pipes in the system.
Now let's see how these components work throughout the whole process. Our main purpose will be to ensure that a continuous cooling effect or refrigeration effect is obtained in this evaporator. As we all know, this evaporator is the component where the refrigeration or cooling actually takes place. This evaporator is placed in the region where we need cooling, and then the evaporator absorbs all the heat of that region and passes that heat to the cold refrigerant, passing through the evaporator coils. Thus, the surrounding environment cools. down, so let's see how this process works. First of all, this compressor starts working.
The job of the compressor is to pressurize or compress the vapor. refrigerant inside this compressor. chamber here In a vapor compression refrigeration system, we commonly use either ammonia or freon as a heat carrier throughout the whole procedure. Now we know that if pressure increases, it also increases the temperature, so when this vapor refrigerant is compressed inside the compressor chamber by squeezing the vapor very tightly together, it will heat. After that, this high-pressure and high-temperature vapor refrigerant will leave the compressor and enter the condenser through this connected pipe. Here, we have a condenser when high-temperature, high-pressure vapor refrigerant enters this cold condenser.
Then the condenser absorbs the heat from the vapor refrigerant and completely converts it into liquid with this condenser.can be water-cooled, air-cooled, or cooled. by any other substance from an external source that will liberate the latentheat of this vapor coming into the condenser, and thus condensing keeps happening. So, in simpler words, the condenser changes the incoming high-temperature, high-pressure vapor refrigerant into a liquid state by changing its phase. Here we had vapor coming in, and now we have liquid refrigerant going out, so the phase is changed now with this high pressure. high-temperature liquid refrigerant will leave the condenser and pass through.
This expansion valve, or throttle valve, using this connected pipe and the high-pressure liquid refrigerant coming from the condenser, will be expanded. Inside this expansion valve, we know that when expansion occurs, the pressure between the molecules decreases. considerably Thus, the temperature falls, so this high-pressure liquid refrigerant will be expanded into a low-pressure liquid refrigerant for inpractical use. At this point, we do not only get liquid refrigerant, but here we actually obtain a mixture of low-pressure, low-temperature liquid and vapor refrigerant. Thus, here we get a mixture of very cold, chilled, low-temperature liquid and vapor refrigerant coming out of the expansion valve, and then this liquid and vapor are mixed. refrigerant will be passed over to the evaporator. We all know that the main cooling effect or refrigeration effect always occurs in the evaporator, so when this low-pressure, very cold, chilled temperature liquid refrigerant will enter the evaporator coils, it will absorb all the heat present on the surface of the evaporator coils by absorbing all the heat from the surrounding region of the evaporator coils.this cold, chilled liquidrefrigerant will completely turn intolow-pressure vapor refrigerant insidethese coils and the surrounding regionof the evaporator will become cold bylosing the heat to this liquid, thus thecooling effect or refrigeration effecthas occurred in the evaporator afterthat this low-pressure vapor refrigerantwill leave the evaporator and enter intothis compressor through this connectedpipe now this low-pressure vaporrefrigerant coming to the condenser willbe again compressed inside thecompressor chamber unconverted to highpressure, high temperature vapor, thenAgain, this high pressureTemperature vapor will be passed to thiscondenser, where it will change phase andwill be converted to liquid, then it ispassed to the expansion valveevaporator, and again to the compressor. so the cycle keeps repeating over and over. over again, and refrigeration or cooling is obtained continuously in the evaporator region throughout the whole process, so this is how vapor The compression refrigeration system works Thank you for watching this video.
