Abstract

The present situation of crude oil heating is analyzed, and theoretically a new type of direct expansion solar assisted heat pump is proposed to heat crude oil. The system combines an electric heating system and a direct-expansion solar-assisted heat pump to heat crude oil. The mathematical model for each season was developed and the different conditions were simulated. The results show that the system performance is excellent in different seasons. In particular, in winter, when the crude oil is heated to 75 degrees Celsius, the heat pump COP reaches 5.35 and the average COP of the system is 1.74. The simulation results show that the system uses segmented heating and energy storage device, which can achieve continuous and stable heating to high temperature under harsh working conditions and high heating load, and reduce the carbon emission by 42% compared with electric heating, achieving the purpose of energy saving and emission reduction, and providing suggestions for using DX-SAHP segmented heat transfer system in areas with harsh environmental conditions.
