Abstract
Proposed is a gas heat-pump system capable of supplying recirculation exhaust gas to an engine using an exhaust gas turbocharger and thus actively controlling an amount of the flowing recirculation exhaust gas and pressure thereof.
Claims14
A gas heat-pump system, comprising:
- a compressor of a conditioning module;
- a gas engine combusting a fuel-to-air mixture and thus generating a drive force of the compressor;
- an exhaust gas turbocharger supplying at least a portion of exhaust gas discharged from the gas engine, as recirculation exhaust gas, to the gas engine;
- and
- a controller controlling an amount of the recirculation exhaust to be supplied,
- wherein the exhaust gas turbocharger comprises:
- a turbine rotated with the exhaust gas;
- and
- an exhaust gas impeller rotated along with the turbine, the exhaust gas impeller being configured to apply pressure to the recirculation exhaust gas and supply the resulting recirculation exhaust gas to the gas engine, and
- the controller controls an amount of the flowing exhaust gas to be supplied to the turbine according to a concentration of harmful substances contained in the exhaust gas.
