Question

In order to recover liquid refrigerant, you must connect one hose to the system. What is the purpose of connecting the hose?

1) To remove the liquid refrigerant from the system
2) To add more liquid refrigerant to the system
3) To measure the pressure of the liquid refrigerant
4) To clean the system

Answer 1

The hose is connected to a refrigeration system to remove the liquid refrigerant, which is a crucial step in maintenance or disposal of cooling appliances.

Step-by-step explanation:

The purpose of connecting a hose to the refrigeration system is to remove the liquid refrigerant from the system. This is part of a process called refrigerant recovery, which is necessary for system maintenance, repair, or before disposing of a cooling appliance. The recovery process involves extracting the refrigerant in a controlled manner, ensuring that it does not escape into the atmosphere, which could be harmful to the environment.

Refrigeration systems operate by using a closed loop where the refrigerant cyclically changes from gas to liquid as it removes heat from the confined space (like the inside of a refrigerator) and then expels it to the surrounding environment.
