Thermodynamic or refrigeration cycle is the mathematical and conceptual models for cooling, air conditioner and refrigeration systems used by the heat pump, refrigeration and air conditioning systems. A heat pump is a device that enables the transfer of heat from one place to another place at a lower temperature. Refrigeration cycle on the other hand, is an arrangement that cools the products in an environment using water or a non-freezing refrigerant. These two processes can also be combined to improve the systems' energy efficiency. In this website, we will study some facts about these systems, their working and their possible future applications.
First of all, we should know what exactly is meant by the term "refrigeration cycle". This cycle is characterized by the transfer of heat energy from a cold refrigerant to a hot one, and between the two places, the process of absorption of liquid takes place. The process of absorption of liquid takes place because of the effect of the heat on the vapor and liquid substances. On the other hand, the process of vapor condensation is caused by the presence of a cold vapour.
The refrigeration cycle, as explained above, is composed of three main stages, and they are: first, the evaporation of water, which takes place inside the cooler reservoir and second, the freezing of the water, which takes place inside the condenser coil and third, the condensation of the gaseous coolants. When these three phases meet, a heat exchange stage takes place, and the temperatures of the refrigerants and the gaseous coolants are balanced. In order to get the required equilibrium, the temperature outside the refrigeration cycle must be colder than the interior of the cycle.
The build-up inside the refrigeration cycle can be defined in terms of four components. First, there is the phase of heat exchange, which is responsible for the change in temperatures and humidity of the refrigerant gases. This stage occurs as the result of the evaporation of water droplets. The end product of this process is the formation of clouds of water droplets around the condenser coils. These clouds are solid enough so that they can hold up against the wind, but as the day passes, the droplets thicken and turn into clouds of ice, which float and fall to the ground.
The next phase of the refrigeration cycle is characterized by the rise of the pressure of the refrigerant gas. As this pressure increases, the pressure of the vaporizing air also rises. In order to overcome this pressure, the condensers must open up and allow the gases to mix with the liquid vapor before they begin to condense into clouds of water droplets again. However, when the temperatures have reached their boiling point and the pressure of the vaporized air exceeds the capacity of the expansion of the gas, the condensers close up, the pressure of the cooled liquid droplets falls, and the process starts all over.
To summarize, the refrigeration cycle mentioned above is a process that takes place in every type of refrigerator. It begins at the point where a cold liquid is pumped into the compressor and then continues to the point where the gas bubbles to create the steam that is dispersed into the atmosphere. Then there is the heating of the liquid to create the hot steam, and the cooling of this hot liquid back into the compressor to produce the cold liquid vapour. The condenser on the back of the refrigerator is responsible for taking away the heat, and the compressor distributes the hot liquid vapour into the surroundings. As you can see, this simple process can be simplified and made even easier to understand using the principles of thermodynamics.
