What do long hoses between the unit and the recovery machine result in?

• A. Decrease in recovery time
• B. Increase in recovery time
• C. No impact on recovery time
• D. Increased refrigerant pressure

Answer: (B)

The correct answer is that long hoses between the unit and the recovery machine lead to an increase in recovery time. This occurs because longer hoses add additional volume to the system, which means it takes more time for the refrigerant to travel through the hoses to the recovery machine. Moreover, longer hoses can increase the overall resistance to the flow of refrigerant due to friction, which further contributes to the time required for effective recovery. The longer the distance the refrigerant must travel, the more time it takes to transfer the refrigerant into the recovery vessel, ultimately delaying the recovery process. Therefore, when setting up a recovery operation, it is typically best practice to use the shortest hoses possible to ensure a more efficient and rapid recovery of refrigerants.
