ACC and water condenser are both used in cooling systems, but ACC uses air as the cooling medium while water condenser uses water.

• ACC (Air Cooled Condenser) uses air as the cooling medium to condense the refrigerant vapor into liquid form.

• Water condenser uses water as the cooling medium to remove heat from the refrigerant.

• ACC is commonly used in air conditioning systems for buildings and vehicles.

• Water condensers are often used in industrial processes and power plants.

• ACC is ...read more

MIG and TIG welding are two common types of arc welding processes used in metal fabrication.

• MIG welding stands for Metal Inert Gas welding, where a wire electrode is fed through a welding gun and melted to join two pieces of metal together.

• TIG welding stands for Tungsten Inert Gas welding, where a non-consumable tungsten electrode is used to create the weld. A separate filler rod may be used if needed.

• MIG welding is faster and easier to learn compared to TIG welding, but TIG ...read more
