Which natural refrigerant is widely adopted in industrial cold storage facilities and dairy refrigeration systems due to zero Ozone Depletion Potential (ODP = 0) and zero Global Warming Potential (GWP = 0)?
Options:
(A) Ammonia (R-717)
(B) CFC-12
(C) HCFC-22
(D) CFC-11
Answer Key:
A
Step-by-Step Solution & Explanation
Anhydrous ammonia (R-717) is the dominant industrial refrigerant because of its zero ODP, zero GWP, exceptional latent heat of vaporization, and superior thermodynamic efficiency.
