Electricity generating and air conditioning system with water heater

An electricity generating and air conditioning system comprising:

• an engine;
• a generator connected to an output shaft of the engine to generate electricity;
• a cooling water heat exchanger to absorb heat from cooling water used to cool the engine;
• an exhaust gas heat exchanger to absorb heat from exhaust gas discharged from the engine;
• a heat pump type air conditioner, which uses the electricity generated from the generator, and comprises a compressor, a directional valve, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger;
• a water-heating heat exchanger to heat water;
• a pre-heater to pre-heat outdoor air blown toward the outdoor heat exchanger;
• and
• heat transfer means to transfer heat from at least one of the cooling water heat exchanger and the exhaust gas heat exchanger to the water-heating heat exchanger during a cooling operation of the heat pump type air conditioner, and to transfer heat from at least one of the cooling water heat exchanger and the exhaust gas heat exchanger to the pre-heater during a heating operation of the heat pump type air conditioner.
