Answer:

1. 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.

2. The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water.

3. The refrigeration cycle repeats when the water vapor transforms to liquid and can be recycled again. Once it becomes liquid, it can now be subjected to evaporation and then compression which continues the cycle.

4. In an evaporator, the pressure is reduced and the heat is being absorbed by the refrigerant.

Answer:

1. How does a refrigerator 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.

2. How does a condenser function?

• A condenser (or AC condenser) is the outdoor portion of an air conditioner or heat pump that either releases or collects heat, depending on the time of the year. The compressor is the heart of the system since it compresses the refrigerant and pumps it to a coil in the form of a hot gas.

3. When does the cycle repeat?

• The refrigeration cycle repeats when the water vapor transforms to liquid and can be recycled again. Once it becomes liquid, it can now be subjected to evaporation and then compression which continues the cycle. In a single-stage vapor compression refrigeration cycle, Freon enters the compressor.

4. What happens to the pressure and heat in the evaporator

• In an evaporator, the pressure is reduced and the heat is absorbed by the refrigerant.
