Consider the following statements in respect of absorption refrigeration and vapour compression refrigeration systems :
1. The former runs on low grade energy.
2. The pumping work in the former is negligible since specific volume of strong liquid solution is small.
3. The latter uses an absorber while former uses a generator
4. The liquid pump alone replaces compressor of the latter.
Which of these statements are correct?
Option (A)
1 and 2
Option (B)
1 and 3
1 and 4
2 and 4
Correct Option:
Question Solution:
Absorber and generator both are used in absorption refrigeration system
Compressor is replaced by an absorber, a pump, generator and a pressure reducing value.
