Question 142Refrigeration & AC - Assistant Engineer

The correct answer is A) direct vapor recovery. The connection scheme shown in figure "B" of the illustrated self-contained recovery unit connection diagrams (Illustration GS-RA-33) supports a direct vapor recovery method. This means that the recovery unit is connected directly to the vapor space of the container being emptied, allowing the vapors to be recovered without transitioning to a liquid state. The other answer choices are incorrect because B) direct liquid recovery would require a connection to the liquid space, C) liquid recovery/push-pull would involve pushing liquid back into the container, and D) vapor recovery/push-pull would involve a more complex setup with both vapor and liquid recovery.
