Summary
This paper proposes a novel low ambient temperature open air cycle heat pump system for recovering CNG pressure energy. Using atmospheric air as the working medium, it can achieve stable operation at low ambient temperature (below -30℃) and high temperature heating (above 80℃). Through experimental testing, it is found that when the ambient temperature changes from 10°C to -20°C, the temperature difference between the inlet and outlet water decreases by 5.26% (8.41°C to 7.99°C); When the water flow changes from 4 to 10 m3/h, the inlet and outlet water temperature decreases by 58.67% (12.17°C to 5.03°C); Achieving a water supply temperature above 80°C under test conditions, and the temperature difference between the inlet and outlet water will not change with the increase of the inlet temperature (within the range of 1.11%), can provide data support and technical reference for the application and optimization of this type of heat pump system.
