Q3
The undesirable property of a refrigerant is
A.
Non-toxic
B.
Non-flammable
C.
Non-explosive
D.
High boiling point
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
It is very important that the refrigerant has a low boiling point, that is it should have the ability to turn into gas easily when it absorbs heat. If it has a high boiling point, the compressor will have to create too much of a vacuum in order to lower the pressure to make vaporization happen.
