Description

In the experiment P2.6.3.2, the temperatures Tf and Th are recorded at the outputs of the expansion valve and the vaporizer. If the difference between these two temperatures falls below a specific limit value, the expansion valve chokes off the supply of coolant to the vaporizer. This ensures that the coolant in the vaporizer is always vaporized completely.
