[0022] In order to make the objectives, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.
[0023] The applicant found through analyzing the prior art that the conventional gas cylinder proportioning refrigerant method needs to release a large amount of gaseous refrigerant in one test due to the small volume of the gas cylinder, so the target concentration refrigerant needs to be prepared multiple times, the process is cumbersome and time-consuming; and the refrigerant is generally stored in liquid state, so it is difficult to control the release amount of the liquid refrigerant when the refrigerant is released, and the method of filling gaseous refrigerant into the gas cylinder also has the problems of high cost and difficult operation, so a device for quickly preparing a large amount of target concentration refrigerant is needed.
[0024] Reference Figs. 1-2 , a refrigerant preparation device provided by the present application is shown, which comprises a high-pressure suction device, a proportioning balloon and a proportioning box provided with a containing space;
[0025] The high-pressure suction device comprises a high-pressure resistant outer pipe, a threaded pusher and a needle cylinder valve 3 for preventing liquid leakage; the threaded pusher is threadedly connected with the high-pressure resistant outer pipe, and one end of the threaded pusher is arranged in the high-pressure resistant outer pipe; the needle cylinder valve 3 is arranged at the suction port of the high-pressure resistant outer pipe; the proportioning box is provided with a puncture device for puncturing the proportioning balloon;
[0026] When the gaseous refrigerant is prepared, the high-pressure suction device injects liquid refrigerant into the proportioning balloon, and places the proportioning balloon in the containing space.
[0027] In the embodiments of this application, addressing the problem of difficulty in producing liquid refrigerant in the prior art, this application provides a solution for transferring gaseous refrigerant to a mixing chamber using a mixing balloon, specifically: "It includes a high-pressure injection device, a mixing balloon, and a mixing chamber with a accommodating space; the high-pressure injection device includes a high-pressure resistant outer tube, a threaded propeller, and a syringe valve 3 for preventing leakage; the threaded propeller is threadedly connected to the high-pressure resistant outer tube, and one end of the threaded propeller is disposed inside the high-pressure resistant outer tube; the syringe valve 3 is disposed within the..." The high-pressure resistant outer tube has an injection port; the mixing chamber is equipped with a puncture device for puncturing the mixing balloon; when producing the gaseous refrigerant, the high-pressure injection device injects the liquid refrigerant into the mixing balloon and places the mixing balloon in the accommodating space. This application uses a mixing balloon to receive the rapidly vaporizing liquid refrigerant and transfer it to the mixing chamber before puncturing it, achieving the technical effect of rapidly producing refrigerant; the volume of the mixing chamber can be selected, and replacing it with a larger volume mixing chamber can achieve the technical effect of rapidly producing large quantities of refrigerant.
[0028] The apparatus for producing a refrigerant in this exemplary embodiment will now be described in further detail.
[0029] In embodiments of this application, the refrigerant production apparatus includes a high-pressure injection device, a mixing balloon, and a mixing chamber with a accommodating space.
[0030] The high-pressure aspiration device includes a high-pressure resistant outer tube, a threaded pusher, and a syringe valve 3 for preventing leakage; the threaded pusher is threadedly connected to the high-pressure resistant outer tube, and one end of the threaded pusher is located inside the high-pressure resistant outer tube; the syringe valve 3 is located at the aspiration port of the high-pressure resistant outer tube; the mixing tank is equipped with a puncture device for puncturing the mixing balloon.
[0031] When the gaseous refrigerant is produced, the high-pressure injection device injects the liquid refrigerant into the proportioning balloon and places the proportioning balloon in the accommodating space.
[0032] It should be noted that the high-pressure suction device of this application is in the shape of a syringe; the high-pressure resistant outer tube is made of high-pressure resistant glass, which can directly draw high-pressure liquid refrigerant and keep it in a liquid state inside the syringe; the syringe valve 3 can prevent the liquid refrigerant inside from overflowing and facilitate the transfer of liquid refrigerant.
[0033] The volume of the mixing chamber in this application can be selected according to requirements, and the target weight of the liquid refrigerant can be determined based on the volume of the mixing chamber and the required target concentration. Furthermore, the mixing chamber of this application is equipped with a door, and the containment space of the mixing chamber is sealed when the door is closed.
[0034] The required amount of refrigerant is injected into a mixing balloon using a high-pressure suction device. The liquid refrigerant inside the balloon rapidly vaporizes, inflating the balloon, which is then tied tightly. The balloon is placed in a mixing chamber, the chamber door is closed, and the balloon is punctured through a pre-drilled hole using a puncture device. The refrigerant in the mixing chamber at this point is the refrigerant of the target concentration. Therefore, the gaseous refrigerant production apparatus of this application can easily and quickly produce large quantities of refrigerant of the target concentration, making it more convenient for experimental use.
[0035] In an embodiment of this application, the suction port is further provided with a fine-tuning valve for discharging a small amount of the liquid refrigerant.
[0036] It should be noted that the fine-tuning valve can release small amounts of liquid refrigerant from the high-pressure suction device. Therefore, when the high-pressure suction device draws in an excessive amount of liquid refrigerant, the fine-tuning valve can be used to release the liquid refrigerant in small amounts multiple times, reducing the weight of the liquid refrigerant in the high-pressure suction device to the target weight.
[0037] In a complete embodiment of this application, the step of preparing a gaseous refrigerant of a target concentration includes: determining the target weight of the liquid refrigerant based on the volume of the mixing chamber and the target concentration required for the gaseous refrigerant;
[0038] Use a high-pressure suction device to draw in a sufficient target weight of liquid refrigerant;
[0039] By using a fine-tuning valve to release liquid refrigerant in small amounts and multiple times until the weight of the liquid refrigerant in the high-pressure suction device drops to the target weight;
[0040] Inject the target weight of liquid refrigerant into the mixing balloon and tie the balloon tightly.
[0041] Place the mixing balloon into the mixing box and close the mixing box;
[0042] Use a puncture device to puncture the mixing balloon through the pre-drilled hole in the mixing chamber to generate a gaseous refrigerant of the target concentration in the mixing chamber.
[0043] In an embodiment of this application, the threaded pusher includes a threaded rod 1 and a piston made of polytetrafluoroethylene. The pusher is fixedly connected to the piston, and the piston is movably disposed inside the high-pressure resistant outer tube, with the diameter of the piston being the same as the inner diameter of the high-pressure resistant outer tube.
[0044] It should be noted that the linear motion of the pusher is converted into rotational motion by the threaded pusher, so that the threaded pusher will not be pushed out of the high-pressure resistant outer tube when it is pushed by the high pressure of the internal liquid refrigerant. The choice of polytetrafluoroethylene as the piston material can also prevent the piston from deforming under high pressure.
[0045] In an embodiment of this application, a nut 2 is provided at one end of the high-pressure resistant outer tube away from the suction port. The threaded through hole of the nut 2 communicates with the interior of the high-pressure resistant outer tube, and the threaded rod 1 is threadedly connected to the nut 2.
[0046] It should be noted that the nut 2 is used to connect with the threaded rod 1, making the manufacture and assembly of the high-pressure suction device simpler.
[0047] In an embodiment of this application, the outer wall of the mixing tank is provided with a through hole for connecting the accommodating space, and a ball valve for turning off the gas is provided at the through hole.
[0048] It should be noted that the gaseous refrigerant in the mixing chamber can be discharged through the through-hole, and gas detection or extraction can also be performed through the through-hole.
[0049] In an embodiment of this application, the mixing tank is further provided with a through hole for the puncture device to pass through.
[0050] It should be noted that a silicone cap should also be installed at the through-hole, and the puncture should have a certain length.
[0051] In an embodiment of this application, the mixing box is provided with a door for placing the mixing balloon.
[0052] It should be noted that the cabinet door is also equipped with a sealing strip to prevent air leakage.
[0053] In embodiments of this application, the mixing chamber is further provided with a gas detection port, an exhaust port, a fan, and a temperature and humidity detector.
[0054] It should be noted that the gas detection port is used to detect the concentration of gaseous refrigerant in the containment space, the exhaust port and fan are used to discharge the gaseous refrigerant in the containment space, and can also be used to stir the gas in the containment space to make the gaseous refrigerant mix evenly with the other gases in the containment space; the temperature and humidity detector is used to detect the temperature and humidity inside the containment space; there are also control buttons to control the start and stop of the fan.
