A reach-in refrigerator is typically larger than a walk-in refrigerator.

• True

• False

The expansion valve reduces the pressure of the refrigerant.

• True

Subcooling occurs after the refrigerant is fully condensed.

• True

• False

Latent heat is absorbed during the evaporation process.

• True
