Yes, you are right @Nikunj Miyani.

D is right because in evaporator latent heat is transfer so the temperature remains same only phase change occurs.

After expansion is right.
But evaporation is also done at constant temperature in VCR.
So, the Answer is 1. After expansion & 2. During evaporation.
But evaporation is also done at constant temperature in VCR.
So, the Answer is 1. After expansion & 2. During evaporation.

Both B and D answers are right. Because in evaporation, Refrigerant Absorbs latent heat at constant pressure. Only state changes, not temperature.

It's after expansion.

Due to sudden drop of pressure at expansion the temperature also drops but after expansion latin heat is received during the evaporation so correct answer is Expansion.

Both answer are correct.
As during evaporation latent heat is added.
As during evaporation latent heat is added.

During evaporation temperature remain constant.
During latent heat is added.
So, both are correct.
During latent heat is added.
So, both are correct.
