Question

When an external equalized TXV is used where should the equalized line be connected?

A Before the evaporator.
B To the suction line down flow from the TXV bulb.
C To the discharge line before the condenser.
D To the suction line before the TXV bulb.

Answer 1

The correct connection point for the equalizer line of an external equalized TXV is to the suction line downflow from the TXV bulb to ensure proper valve operation and cooling performance.

Step-by-step explanation:

When an external equalized TXV (Thermostatic Expansion Valve) is used, the equalizer line should be connected to the suction line downflow from the TXV bulb. This means that the correct answer is B, 'To the suction line down flow from the TXV bulb.' Connecting the equalizer line in this manner ensures proper functioning of the TXV by balancing the pressure in the suction line with the pressure inside the evaporator. If the equalized line were connected incorrectly, it could result in inadequate cooling performance or other operational issues in the refrigeration cycle.
