Cooling systems are essential for regulating temperature in various environments, from homes to industrial settings. They work by removing heat from a designated area, ensuring comfort and preventing overheating of equipment. Common types include air conditioning units, refrigeration systems, and cooling towers, each designed for specific applications. These systems often use refrigerants, which absorb and release heat as they circulate. In residential settings, air conditioners cool indoor air, while refrigerators keep food fresh. In larger facilities, cooling towers dissipate heat from machinery, maintaining optimal operating conditions and enhancing efficiency.
