Problems solved by technology

[0003] There are usually two types of throttling devices used in traditional refrigeration systems, one is throttling through thermal expansion valves or electronic expansion valves, the other is throttling through fixed orifice plates, capillary tubes, and U-shaped tubes. During the expansion process, the pressure and temperature of the refrigerant will decrease, and at the same time, a part of the internal energy will be converted into kinetic energy, which will increase the flow rate of the refrigerant. The traditional refrigeration system does not use this part of the energy converted into kinetic energy, resulting in Waste of part of energy, refrigeration systems in the prior art have not effectively utilized this part of energy

Abstract

The invention discloses a throttling expansion device, which comprises a housing, a magnetic vane flywheel and a stator coil. The magnetic vane flywheel includes a flywheel body and vanes, and the magnetic vane flywheel is rotatably arranged inside the housing. The outside of the magnetic blade flywheel is provided with a stator coil, and the housing is provided with a liquid inlet pipe and a liquid outlet pipe. The outlet of the liquid inlet pipe is opposite to the blades of the magnetic blade flywheel. Rotating under the impact of the liquid, the stator coil cuts the magnetic force line to generate an induced current for external output. The parts of the throttling expansion device are simple in structure, and can realize the throttling and expansion of the refrigerant, and at the same time convert the kinetic energy generated during the throttling and expansion into electric energy, thereby improving the utilization rate of energy; the invention also discloses a Refrigeration system with throttling expansion device.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a throttling expansion device and a refrigeration system with the device. Background technique [0002] In a commonly used refrigeration device, the refrigerant undergoes refrigeration cycles such as compression, condensation, throttling, and evaporation in a closed loop. In the refrigeration cycle process, the refrigerant is first adiabatically compressed into high-pressure vapor in the compressor, condensed into a high-pressure normal temperature liquid in the condenser, and expanded through the throttle valve, and then returned to the evaporator to absorb heat and evaporate into vapor. compressor. [0003] There are usually two types of throttling devices used in traditional refrigeration systems, one is throttling through thermal expansion valves or electronic expansion valves, the other is throttling through fixed orifice plates, capillary tubes, and U-shaped tubes. During the exp...
