Textbook Question
Chapter 4, Problem 1RQ

Where would a technician encounter freezing temperatures when working with liquid refrigerant?

Expert Solution & Answer
Check Mark
To determine

The condition where the technician will encounter the freezing temperatures while working with liquid refrigerant.

Answer to Problem 1RQ

A technician will encounter a freezing temperature when the liquid refrigerant gets mixed with the atmosphere and absorbs the heat to produce a cooling effect.

Explanation of Solution

While working with the liquid refrigerants, it is essential to take preventions before doing any operation with liquid refrigerants. Liquid refrigerants can be harmful in nature. Liquid refrigerant can cause a high temperature drop, if it leaks out of the cylinder.

When liquid refrigerant leaks out from the cylinder it produces a drop in local temperature as, the liquid refrigerant absorbs heat from the surroundings and cool it down to a lower temperature.

As a technician is working with liquid refrigerant, he will feel a freezing temperature when there is a leak in cylinder.

Conclusion:

Thus, a technician will encounter a freezing temperature when the liquid refrigerant gets mixed with the atmosphere and absorbs the heat to produce a cooling effect.
