Heat recovery

Heat recovery can refer to:

• Cogeneration or combined heat and power (CHP), use of a heat engine or power station to generate electricity and useful heat at the same time
• Energy recovery, any technique or method of minimizing the input of energy to an overall system by the exchange of energy from one sub-system
• Energy recycling, process of using energy that would normally be wasted
• Exhaust heat recovery system, conversion of waste heat energy in exhaust gases into electric or mechanical energy reintroduced on the crankshaft
  • MGU-H, an electrically assisted turbocharger and electric turbo-compound used in Formula One cars from 2014 to 2025
• Goodsprings Waste Heat Recovery Station,
• Heat recovery steam generator, a heat exchanger that recovers heat from a hot gas stream
• Heat recovery ventilation or mechanical ventilation heat recovery, ventilation system that recovers energy by operating between two air sources at different temperatures to reduce heating and cooling demands of a building
• Waste heat recovery unit, an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency
• Water heat recycling, use of a heat exchanger to recover energy and reuse heat from drain water
