Based on in-depth research on hybrid power technology and gas heat pump air conditioning systems, this achievement integrates the hybrid power device and the heat pump air conditioning system into an organic whole to establish a hybrid gas engine-driven heat pump independent energy supply system. The system obtains domestic hot water by recovering residual heat from gas engine cylinders and exhaust gas, thereby realizing the functions of air conditioning in summer, heating in winter, and providing domestic hot water throughout the year. The system optimizes the adjustment of cold, heat and electrical loads to ensure that the gas engine always operates within the optimal operating conditions. The output power of the gas engine has an upper critical point power and a lower critical point power. When the air conditioning demand load is greater than the upper critical point power, the output power of the gas engine stabilizes at the upper critical point, and the insufficient difference power is discharged by the energy storage device.(or introduce external grid power) drive the motor to supplement; when the air conditioning demand load is between the two critical points, the gas engine automatically adjusts the speed to adapt to the demand load, and the energy storage device does not work; When the air conditioning demand load is less than the power at the lower critical point, the output power of the gas engine is stable at the lower critical point, and excess power drives the generator to generate electricity. Part of the AC power generated by the generator is transmitted to the user through the circuit control module, or converted into DC power through the inverter. After that, it is stored in the energy storage device. The energy storage device is a key equipment that plays a role in cutting the peak and filling the valley of the engine power. The engine and the energy storage device couple the power through a power distribution device. The power distribution device inputs torque to the compressor, thereby driving the air conditioning system. The hybrid gas engine-driven heat pump independent energy supply system mainly solves the problems of cold (heat) load and domestic hot water demand in buildings. Power generation is not its main purpose. And because the system is small, the amount of power generated during normal operation is very small and can be consumed internally by the system. When it generates electricity alone, it is not as efficient as existing large-scale thermal power plants, but it can be used as an emergency power supply backup system in case of power outages due to power grid collapse or accidents.
