engineering recuitment NCL Assistant Foreman (Trainee) Mock Test 2024 Refrigeration and Air Conditioning Refrigeration Cycles and Devices Vapour Absorption (V-A) Cycle
Consider the statements in respect of vapour absorption 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 latter.
