Refrigerant evaporators are critical components in the refrigeration cycle, acting primarily as heat exchangers that absorb heat from the environment or product and transfer it to the refrigerant. Commonly used in industrial and commercial applications such as air conditioning systems, cold storage warehouses, and food processing facilities, these devices facilitate the transition of the refrigerant from a liquid into a gaseous state. By doing so, they not only cool the surrounding area but also help maintain optimum temperature controls for preserving perishable goods and ensuring comfortable indoor climates.
