What function is performed by a condenser in a refrigerant?
A. To deliver the heat to the heat pump.
B. To deliver the heat to the evaporator.
C. To deliver the heat to the refrigerator.
D. To deliver the heat to the atmosphere.

Hint: The refrigerant is a device that helps to cool the space (that our products are places). It consists of many internal parts and devices to achieve its requirement. A refrigerant may consist of a condenser, evaporator, compressor and pressure valve.

Complete step by step answer:
As we all know that the refrigerant is used in many places to keep the products cool and remain un-rotten to many days. Some products like milk products, beverages need to be stored in cool places for good performances, so the refrigerant is helpful in such a way.
The refrigerant consists of Evaporator that helps to remove the heat from the space and keeps the space cool, whereas the condenser is another device in the refrigerator that helps to reject the heat to the atmosphere which is observed in the space.
There were other devices like compressor and pressure valve; the compressor will increase the pressure of the liquid or gaseous refrigerant. The pressure valve will help the refrigerant to remain the pressure constant, so there will be no loss and no gain of pressure in further process.

So, the correct answer is “Option D”. Therefore, the correct answer is that the condenser rejects the heat to the atmosphere.

Note:
The working aim of the evaporator and the condenser looks quite similar, be sure that the condenser is used to reject the heat to the atmosphere and the evaporator is used to observe the heat from the space.
