What Is Refrigeration?
Blog: What Is Refrigeration?
Perhaps it is my ignorance, but when I think of a refrigeration mechanic my mind immediately assumes ‘fridges’. So, if my air conditioner stops working, intuitively I’d think to contact an air conditioning mechanic to provide a solution, and not a refrigeration mechanic. And this is partly right, but a refrigeration mechanic is that, and much more. If we first understand what ‘refrigeration’ actually is, we will learn why a refrigeration mechanic is more than just ‘fridges’ but also the right person to resolve your air conditioning troubles.
Refrigeration is the process of removing heat from a space or substance, in order to lower its temperature. It is called refrigeration because it involves the use of a refrigerant, a substance that is used to absorb and remove heat. The refrigerant is circulated through a closed system of refrigeration pipes, and as it absorbs heat, it vaporizes and turns into a gas. The gas is then compressed, which causes it to become hot. The hot gas is then passed through a condenser, where it releases the heat it has absorbed and condenses back into a liquid. The liquid refrigerant is then passed through an expansion valve, which lowers its pressure and causes it to vaporize again. As it vaporizes, it absorbs heat from its surroundings, completing the refrigeration cycle.
Refrigeration is used in a variety of applications, including air conditioning, which is the process of cooling and dehumidifying the air in a building or vehicle. In the electrical sector, refrigeration is often used to keep electrical equipment, such as transformers and generators, cool and operating efficiently. It is also used in the food and beverage industry to preserve perishable products and keep them fresh.
So when you think of refrigeration and refrigeration mechanics, we are not limited to repairing fridges. We deal with the process of refrigeration, which is utilized by a myriad of applications.
