Which outcome occurs when a refrigerant undergoes rapid expansion through throttling valve in AC unit?

💡 Explanation

When refrigerant expands through a throttling valve, the Joule-Thomson effect causes temperature drop because intermolecular forces must be overcome, converting internal energy into kinetic energy and causing the phase change. Therefore temperature decrease happens, rather than pressure increase, retarded transition, or entropy reduction since the process is isenthalpic.
