摘要：Two novel air-source heat pumps, mainly consisting of vortex tube, ejector and ambient air heat exchanger, are proposed to absorb heat from low-temperature environment. Such heating system will be supplemented to the LNG regasification process, taking the place of water-bath heater, to minimize electricity or natural gas consumption. In these two novel heating systems, due to the gas temperature drop at the cold end of the vortex tube, the natural gas can continue absorbing heat from the environment in the ambient air heat exchanger. In addition to giving a detailed description of the system, a mathematical quantitative model is also established. Through setting specific working conditions, the performance of the two heating systems, energy consumption and energy saving ratio relative to the traditional heating system are calculated and analyzed.The results show that when the gas temperature requirement is between 5 ℃ and 30 ℃, the energy saving ratio of the heating system without ejector is above 50%, while that of the heating system with ejector is above 90%.
