The 4 Steps in Your Basic Refrigeration Cycle
|
Each of those 4 steps is definitely a necessary part in the refrigeration system, but not all refrigeration systems have just 4 steps. Today, I am going to investigate just those 4 basic refrigeration cycle steps. 1. Evaporation In every basic refrigeration cycle, you will find that the first step is evaporation. Usually, a liquid coolant is into contact with a heat source at a low pressure. The refrigerant material heats up and the boils which creates a vapor. This is usually done by an evaporator. 2. Compression Well, this is the second step needed for a cooling system. Each basic refrigeration cycle has a compression unit, but there are times when you may have more than one compressor for this activity, but this is not usually common place. A motor is usually used to raise the pressure of the vapor from the first step. This will hopefully raise the temperature of those vapors and cause the condensation needed for the third step. 3. Condensation This is a basic refrigeration cycle step. This is where your high pressure vapor meets an interesting step creating a high-pressure liquid. This is important and usually accomplished by the use of another little motor. 4. Expansion This is our final step in the basic refrigeration cycle. The condensed liquid is now throttled via a valve, or other method. This is the complete refrigeration cycle, and once this is done, we start over at step one. As you can see, those refrigeration units do a lot of work, and hopefully, you never have to think about your refrigeration unit. Proper maintenance from time to time will insure that everything is doing what it is supposed to be doing, and that your refrigeration unit is working properly. Of course, you will probably not realize that one of the 4 basic refrigeration cycle steps is not working properly until it is too late. However, you can keep your unit clean and free from debris. Refrigeration units need air to breath, so make sure the ventilation system is cleaned regularly for a longer lifespan.
