Claims19
A gas heat-pump system comprising:
- a compressor of an air conditioning module;
- a gas engine 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
