Exhaust air heat pump
An exhaust air heat pump is an air-source heat pump that recovers heat from a building's ventilation exhaust air; because its capacity is limited, it needs a supplementary heat source.
Exhaust gas
Exhaust gas, also known as car exhaust or tailpipe emissions, is the mixture of gases and particles that leaves an internal combustion engine or boiler after fuel burns.
Exhaust gas recirculation
Exhaust gas recirculation (EGR) is an engine emission control technique that routes exhaust gas back into the intake, cutting combustion temperatures and nitrogen oxide emissions in diesel and gasoline engines.
Exhaust system
An exhaust system is the set of pipes and components that carries engine combustion gases to the tailpipe, using mufflers to cut noise and catalytic converters to cut pollution.
