cooling system in refrigerator

cooling system in refrigerator

1. 4. Freezer - in the evaporator (freezer), cooling agent (in liquid) evaporates and absorbs latent heat from inside the refrigerator

2. 1. Compressor - compresses cooling agent (gas) to increase pressure and its temperature.

3. 3. Expansion valve - cooling agent (liquid) flows through expansion valve.. This valve has tiny hole which allows liquid at high pressure is ejected into the evaporator tube which is at lower pressure.. Liquid changes to gas

4. 2. Condenser - in the condenser, cooling agent (gas) releases latent heat during condensation

5. 5. Cooling agent/Freon - cooling agent in gas flows out from evaporator to the compressor
