The invention discloses a CO2 high-temperature heat pump system. The CO2 high-temperature heat pump system comprises a condenser, a vortex tube, a compressor, a gas-liquid separator, a first expansion valve, a second expansion valve and an evaporator, wherein an outlet of the compressor is connected with an inlet of the vortex tube; a high-temperature outlet of the vortex tube is connected with a refrigerating fluid inlet of the condenser; a low-temperature outlet of the vortex tube is connected with the gas-liquid separator; a refrigerating fluid outlet of the condenser is connected with the gas-liquid separator via the first expansion valve; a gas outlet of the gas-liquid separator is connected to an inlet of the compressor through a gas suction tube; a liquid outlet of the gas-liquid separator is connected to a first inlet of the evaporator via the second expansion valve; and a first outlet of the evaporator is connected with the gas-liquid separator. The vortex tube and an ejector are arranged on the heat pump system, a vortex shedding effect of the vortex tube is utilized, water with high temperature can be provided by the condenser under the condition that a heat pump has constant exhaust pressure, and the application range of the high-temperature heat pump is expanded further; and moreover, the air suction pressure of the compressor can be increased with the aid of the ejector, and the energy efficiency of the heat pump is improved.
Description
[0001] 【Technical field】 [0002] The invention belongs to the technical field of mechanical engineering and relates to a CO 2 High temperature heat pump system. [0003] 【Background technique】 [0004] Mechanical compression heat pump technology uses a small amount of high-grade mechanical energy to complete the cycle of refrigerant in the system by using a compressor, extract heat from a lower temperature heat source and heat other media, that is, by consuming a small amount of high-grade energy, the low Grade energy is upgraded to high grade energy. The advantage of high-temperature heat pump technology is that it can use a heat source at a lower temperature of 40°C-50°C to generate hot water as high as 80°C-120°C, and provide the energy originally discharged as waste heat to occasions that consume a large amount of heat energy. The utilization rate of energy is increased, and it has great advantages in energy saving and environmental protection. [0005] At present, heat...
