At the same time, during the operation of the system, the refrigerant usually contains impurities. There is no device to remove or filter impurities inside the ordinary gas-liquid separator, which will cause impurities to enter the compressor. Long-term operation may cause damage. Ordinary The current carbon dioxide gas-liquid separator has a certain degree of lack of consideration in this regard

Embodiment 1
[0021] Embodiment one: see attached figure 1 shown.
[0022] A gas-liquid separator used in a carbon dioxide heat pump system is applied to the carbon dioxide heat pump system. The gas-liquid separator includes a sealed tank body 6 , and a partition plate 7 with holes for dredging the air flow and balancing the pressure inside the sealed tank body 6 is arranged in the sealed tank body 6 . The perforated partition 7 includes a plate body, and several circular through holes are opened on the plate body. The perforated partition 7 divides the inner space of the sealed tank body 6 into an upper part and a lower part. The upper part is provided with a gas-liquid two-phase inlet 1 and connected with a gas-liquid two-phase inlet pipe, and the other end of the gas-liquid two-phase inlet pipe is connected with the evaporator in the carbon dioxide heat pump system. The top of the lower part is provided with a gas outlet 2 and is connected with an air outlet pipe. The air outlet pipe ...

The invention relates to a gas-liquid separator adopted by a carbon dioxide heat pump system. The gas-liquid separator comprises a sealing tank body, wherein a porous clapboard is arranged in the sealing tank body; the inner space of the sealing tank body is separated into an upper part and a lower part through the porous clapboard; the upper part has a gas-liquid two-phase inlet and is connected with a gas-liquid two-phase inlet pipe; the top of the lower part has a gas outlet and is connected with a gas outlet pipe; the bottom of the lower part has a liquid outlet and is connected with a liquid outlet pipe; a control valve is arranged on the liquid outlet pipe; the liquid outlet pipe is connected with the gas outlet pipe through the control valve and forms a heat regenerator outlet; the gas outlet and the liquid outlet are provided with filtering nets; and the outer wall of the sealing tank body is provided with a defrosting device. The degree of superheat of the system is regulated through the opening degree of the control valve which is arranged on the liquid outlet pipe, and the performance of the system is improved; due to the defrosting device, the gas-liquid separator is suitable for a low-temperature environment; and meanwhile, the filtering nets are arranged at the gas outlet and the liquid outlet, so that the gas and liquid can be effectively filtered, and reliable operation of the system is guaranteed.
Description
technical field [0001] The invention relates to a gas-liquid separator, in particular to a gas-liquid separator suitable for a carbon dioxide heat pump system. Background technique [0002] In the field of carbon dioxide heat pumps, the gas-liquid separator can store the refrigerant in the internal part of the system, prevent the compressor from liquidating, expand the system capacity, and adjust the system pressure. [0003] The gas-liquid separator of an ordinary heat pump consists of a tank, a gas inlet and outlet, a gas-liquid two-phase inlet, an oil return, and a liquid return hole. The internal pipeline pressure of the ordinary heat pump system is low, while the internal pipeline pressure of the carbon dioxide heat pump system is 3 times or even more than that of the ordinary heat pump. It is an inevitable trend of system optimization to fully and reasonably adjust the system pressure through the components of the carbon dioxide heat pump system. [0004] When the car...
