Background
The oil field carries out low-carbon transformation on the gas heating furnace, but the natural gas is complex and unstable in composition due to the special working condition of the field well site, so the transformation is not thorough, and the smoke emission can not reach the national standard; and the electric heating energy consumption and the operation cost are high, and the national energy saving and consumption reduction policy is not met. Therefore, the oil field is widely popularized to the application of green new energy technology in heating equipment, and the heat pump technology is one of the new energy technology.
However, the heating process of the existing heat pump is not separated from the electric pump circulation, namely: the heat energy generated by the heat pump is firstly transferred to the convection water (or other heat medium to be heated) for absorption, and is brought out by the circulating pump through the continuous flow of the pipeline repeatedly, and then indirectly transferred to the heated material. This brings about two drawbacks: the temperature of the circulating water (or other heat medium to be heated) is lower than the temperature generated by the heat pump, and the difference is more than 20 ℃, so that the temperature difference is much smaller when the heat end is used for heating, and the heat exchange effect is seriously affected; the second is that the circulation pump itself requires power consumption and generates maintenance costs, which in turn increases the running costs.
