Heat recovery from refrigeration systems captures thermal energy rejected by the condenser to pre-heat process water for applications like sanitation or boiler feed. This process improves overall plant efficiency by reducing the load on primary heating systems and cooling towers. It is a key strategy in industrial energy management and preliminary heat integration design.
