Title:
HEATING SYSTEM EMPLOYING NATURAL GAS
Document Type and Number:
WIPO Patent Application WO/2022/121486
Kind Code:
A1
Abstract:
A heating system employing natural gas. The heating system comprises an internal combustion engine (100), a generator (300), a waste heat recovery device (200) and an air source heat pump unit. The internal combustion engine (100) is respectively connected to the waste heat recovery device (200) and the generator (300). Flue gas and cylinder liner water generated by the internal combustion engine (100) are transmitted to the waste heat recovery device (200). The generator (300) is connected to the air source heat pump unit, and domestic hot water is provided by means of the air source heat pump unit. The heating system employs natural gas as a resource to generate electric energy, and supplies the energy to an air source heat pump unit. Domestic hot water is provided by means of the air source heat pump unit. In addition, an air heat exchanger (403) is used to absorb heat in the air inside the air source heat pump unit, thereby reducing energy consumed by the air source heat pump unit, and reducing the costs incurred in providing domestic water. Moreover, waste heat generated by combustion of natural gas is recovered by means of a waste heat recovery device (200), thereby increasing the use efficiency of the natural gas.
