What Refrigeration Cycle Is Composed Of And How It Works

956 words - 4 pages

The refrigeration cycle is composed of 5 main components which will be explained in this essay. There are many different factors that allows refrigeration to work. We’ll also go over the basic principles of refrigeration, how the refrigeration cycle works, and types of heat transfer.

First, I will discuss exactly what happens on the low pressure, low temperature side of the refrigeration system. The refrigerant runs through the expansion valve which regulates the flow of the refrigerant between the high and low side. The low pressure, cool liquid then goes to the evaporator where heat from the inside air is absorbed and changes the liquid to a gas. The hot, low pressure gas then moves to the compressor where it then compressed to a high pressure, hot gas.

Next, the refrigerant moves on to the next side of the refrigeration cycle, which is the high pressure side. The refrigerant leaves the compressor as a high temperature, high pressure gas and then moves to the condenser. At the condenser, the hot gas is condensed back to a liquid and it’s heat is given to the outside air. The refrigerant then moves from the condenser to the expansion valve where the amount of flow is restricted and lowers the pressure as the refrigerant leaves the expansion valve.

There are three different types of ways heat can be transferred, and that is conduction, convection, and radiation. Radiation is a heat transfer that involves heat absorption such as the sun producing heat and the Earth absorbing the heat. Second is conduction, which is the process of heat being transferred through metal. an example of this would be heating up one end of a metal pipe and the other end of the pipe will begin to get hotter. Lastly is convection, which is heat transferring through a medium such as water, air, or refrigerant. Convection is the type of heat transfer that is used in air conditioning system that is in you home and even in your car.

There have been multiple types of coolants used to keep items cooled or frozen over the last 100+ years. It began with iceboxes, where families would store their food and other items needed to keep cool. It was an efficient method to preserve food, it just must’ve been a hassle having to put ice in it every so often. Dry ice has been used for food preservation because of how cold it is compared to regular ice. Ammonia was used as a refrigerant in early refrigerators in such ways that refrigerants are used now a days, but it wasn’t used long because of how dangerous it is. It is extremely flammable and very dangerous to inhale. Refrigerants used today are a lot safer because they’re not as flammable as refrigerants used in the past like ammonia.

There are three different types of heat that take place in heat transfer, latent heat, sensible heat, and...
