Tip & How-To about Refrigerators
Reference to refrigeration.
There are 4 main components in a refrigeration system 1. The compressor. 2. The condenser. 3. The expansion device. 4. The evaporator. all refrigeration systems work the same even air conditioning. How you control them is the problem.
What you must always know is that Heat always goes to Cold never the other way round.
Hot gas comes from the compressor and is sub cooled by the condenser, it then becomes a liquid before it reaches the expansion device. It is then squeezed through the expansion device into a larger space where it evaporates attracting all the heat it can from the space needing to be chilled, it then transfers this heat from the said space back to the compressor where it is then compressed again taking the heat from the space and the compressor to the condenser where it gives up it's heat to the atmosphere. It then goes back into cycle and repeats over and over again. That is why it is vital that there is airflow throughout the system. once there is a blockage and no airflow it is just like you and me, we get hot and do not feel like working, we slow down and eventually stop. That is how a refrigeration system works, how you control it is another matter. More later.
