They also minimize heat lost to the environment by recovering some heat.
Heat exchangers are used in the cooling and heating process. Different heat exchangers work differently. Despite that, they all directly or indirectly expose a warm element to a cool element for heat exchange. The heat exchanger has fans, condensers, coolants, and other components that work together to heat and cool the air efficiently. Heat exchanges are used to preheat cold fluid using heat from a hot fluid exiting the system. This is energy efficient as the heating is done without extra energy. Heat exchangers are used in the commercial industry for power plant generation to offer a safe, reliable, and efficient energy supply. Heat exchangers are also used in the food industry to cool or heat some products like food pastes for production to continue. Heat exchangers are also used in ethanol production by using a network of heat exchangers to utilize waste heat to save energy. They are used in different food productions. One example is in sterilizing juices by using flash pasteurization. Heat exchangers heat liquids at 95 degrees Celsius. Industrial plants also use heat exchangers to recover condensate, thus reducing the costs of makeup water treatment. They also minimize heat lost to the environment by recovering some heat. You will also find heat exchangers in refrigerators in your home. A coolant passes through a pipe found inside your refrigerator to absorb and expel heat. Your air condition also uses a heat exchanger to remove heat in a room. Central heating uses heat exchangers to warm and distribute heat in your home using a blower inside the heating system.
