Refrigerant Recovery Process Explained

What is the key component to connect a hose to for recovering liquid refrigerant from an air conditioning system?

a) compressor suction valve

b) compressor discharge valve

c) liquid line

d) top of the condenser

Answer:

To recover liquid refrigerant, one must connect a hose to the liquid line.

To recover liquid refrigerant from an air conditioning system, one must connect a hose to the liquid line, which is option c). The condenser is the component of an air conditioner that converts gas into liquid by removing heat from the gas, causing it to condense. Once the refrigerant is condensed into a liquid, it flows through a pressure-reducing valve and then to the outdoor evaporator coils.

Here, during the cooling cycle, the refrigerant is cooled and expands, reversing the direction of fluid flow compared to the heating cycle. The liquid refrigerant then enters the evaporator, where it absorbs heat and becomes a gas again, thus completing the refrigeration cycle.

Recovering liquid refrigerant is an important process to ensure proper maintenance and safety of air conditioning systems. By connecting a hose to the liquid line, technicians can safely remove the refrigerant for recycling or disposal, preventing harm to the environment and ensuring efficient operation of the system.
