Refrigerant should be recovered from the condenser outlet if the condenser is?

Recovering refrigerant from the condenser outlet when the condenser is below the receiver is vital for proper system functionality and safety. In such a setup, refrigerant can trap vapor as it migrates back to the compressor through the condenser. This means that any refrigerant needs to be recovered from the bottom to ensure that liquid refrigerant doesn’t remain trapped in the condenser, which could lead to inefficiencies or even damage to the system.

When recovering refrigerant, it’s essential to consider the flow of refrigerant and the positioning of system components. If the condenser is located at a lower elevation than the receiver, any recovery work needs to focus on the outlet to ensure that it is clear of refrigerant. This helps in maintaining optimal pressure levels within the system and prevents environmental harm that could result from refrigerant leaks during the recovery process.

In contrast, other scenarios such as the condenser being above the receiver or on the roof present different issues that would necessitate different recovery methods, or they may not require recovery from the outlet specifically. The presence of a leak, while critical to address, does not dictate where the refrigerant should be recovered from concerning the system's vertical layout and its operational efficiency.
