What is meant by refrigeration cycle?
a reverse thermodynamic cycle whereby heat is transferred from a body with a lower temperature to a body with a higher temperature owing to the expenditure of work. Refrigeration cycles are used in refrigerating machines and in gas refrigerators.
What are the steps in refrigeration cycle?
The Vapor Compression Refrigeration Cycle, Step By Step
- Step 1: Compression. The refrigerant (for example R-717) enters the compressor at low temperature and low pressure.
- Step 2: Condensation. The condenser is essentially a heat exchanger.
- Step 3: Throttling and Expansion.
- Step 4: Evaporation.
What is refrigeration cycle in HVAC?
An air conditioner works using a thermodynamic cycle called the refrigeration cycle. It does this by changing the pressure and state of the refrigerant to absorb or release heat. The refrigerant (aka coolant) absorbs heat from inside of your home and then pumps it outside.
Why is the refrigeration cycle important?
The purpose of the refrigeration cycle is to remove the heat in a given area and reject it outside. Less heat means a colder room!
How does a fridge work?
Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect. When you release the contents into the lower pressure open space, it turns from a liquid to a gas.
How does a refrigerant work?
As refrigerant absorbs heat from indoor air, it transitions from a low-pressure gas to a high-pressure liquid. The refrigerant then cools down and turns back into a low-pressure gas. Another fan located inside the home blows air over the cool coils to distribute the resulting cold air throughout the building.

How does refrigeration work?
How does the refrigeration cycle work in a fridge?
How does refrigeration works? Compression. When you plug in the refrigerator, the compressor starts first. Condensation. At the condenser, the refrigerant is at high temperature, so the heat exchange takes place between the refrigerant and the surroundings. Expansion and Throttling. Evaporation.
What does the refrigerant do in refrigeration cycle?
The refrigerant enters the compressor as a low pressure superheated gas.
What is the best temperature for refrigeration?
Keep your appliances at the proper temperatures. Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these temperatures and are generally inexpensive.
What is the life cycle of a refrigerator?
The average life expectancy for a properly maintained refrigerator is between 14 and 17 years, depending on model and size. Compact refrigerators typically run for 14 years on average, while a standard refrigerator will run up to 17 years.
