Q1. What is refrigeration cycle ?
Ans. 
Refrigeration cycle is a process in which refrigerant absorbs heat from a low-temperature area and releases it in a high-temperature area.
• Refrigerant absorbs heat from the evaporator coil and evaporates into a gas.

• The compressor then compresses the gas, raising its temperature and pressure.

• The hot gas flows through the condenser coil, releasing heat and condensing back into a liquid.

• The liquid refrigerant passes throug...read more

Q4. Main compartment in refrigerationcycle ?
Ans. 
The main compartment in a refrigeration cycle is the evaporator.
• The evaporator is where the refrigerant absorbs heat from the air or water being cooled.

• It is located inside the refrigerator or air conditioning unit.

• The evaporator coils are filled with the refrigerant, which evaporates as it absorbs heat.

• The evaporator is connected to the compressor, which then compresses the refrigerant gas to raise its temperature.

Q5. How refrigeration work ?
Ans. 
Refrigeration works by removing heat from a space or substance to lower its temperature.
• Refrigerant absorbs heat from the space or substance being cooled

• The refrigerant then moves to the compressor where it is compressed and heated

• The hot, pressurized refrigerant moves to the condenser where it releases heat and condenses into a liquid

• The liquid refrigerant moves to the expansion valve where it expands and cools down

• Th...read more
