The refrigerant passing through the primary filtering mechanism 204 is acted by the rotating motor 201 in the separation chamber 202, the refrigerant passes through the rotor 210 and enters the interior of the rotor 210, the reticular rotor 210 shell can absorb liquid in the refrigerant and throw the liquid onto the inner wall of the separation chamber 202, the liquid absorbing cotton in the rotor 210 can further absorb the liquid in the refrigerant and drain the liquid onto the truncated cone-shaped liquid collecting table 206 and pass through the liquid outlet 211 to the metal mesh pad 212 of the separation chamber 202, the rotor 210 is rotated by the rotating frame 209 to continuously collide and baffle the refrigerant, and the liquid in the refrigerant is thrown to the inner wall of the separation chamber 202 and is converged downwards onto the metal mesh pad 212 of the separation chamber 202 under the action of centrifugal force; after the liquid in the liquid-guiding pipe 205 and the liquid generated on the rotator 210 reach the metal mesh pad 212, impurities remain on the metal mesh pad 212, the liquid passes through the metal mesh pad 212 to the bottom of the separation chamber 202, and is discharged from the liquid outlet 208, the liquid can be recovered and recycled, and the low-temperature low-pressure refrigerant gas after separation is discharged into the compressor 3.

The low-temperature low-pressure refrigerant gas is compressed by the compressor 3 to form high-temperature high-pressure gas which enters the pipe box 401, the high-temperature high-pressure gas enters the seal head 408 from the pipe bundle 403 arranged above the partition plate 414, then the refrigerant in the seal head 408 enters the pipe box 401 from the pipe bundle 403 arranged below the partition plate 414, and finally flows out to the liquid storage tank 5 for storage; in the above process, cold water is injected into the tubular heat insulation cylinder 402 through the water inlet 413, and flows from left to right and from bottom to top due to the structural design of the upper baffle 406 and the lower baffle 412, the cold water contacts the tube bundle 403 disposed below left to fully absorb heat and raise temperature, then contacts the tube bundle 403 above left to absorb heat, the water temperature gradually raises from left to right, and meanwhile, the water temperature gradually raises from bottom to top, the high-temperature and high-pressure gas in the tube bundle 403 above left can raise temperature due to the high-temperature and high-pressure gas continuously input by the compressor 3 even if the heat is fully absorbed and lowered, so that the tube bundle 403 above the baffle 414 is mainly gas, even if liquid is blown into the seal head 408 by the gas, the guide plate 410 is limited by the baffle 220 and forms a certain angle downwards in the seal head 408, and the low-temperature and high-pressure liquid is guided onto the cut block 409 below the seal head 408 and flows into the tube box 401 along the tube bundle 403 below the baffle 414.

The balance pipe communicates the balance pipe interface 706 with the outlet of the fin-type evaporator 1, and communicates a bulb arranged at the outlet of the fin-type evaporator 1 with the bulb interface 705, wherein the balance pipe is arranged at a position slightly far away from the bulb, the balance pipe transmits the actual pressure of the outlet of the fin-type evaporator 1 to the valve body 718, and the bulb converts the temperature of the outlet of the evaporator into a pressure value and feeds the pressure value back to the valve body 718; the adjusting handle 701 rotates the threaded rod 711, so that the threaded rod 711 drives the adjusting spring 704 to move through the adjusting block 703, and the pressure of the adjusting spring 704 to the piston rod 715 is adjusted to meet the pressure requirement of the corresponding refrigerant. When the temperature sensing bulb detects that the temperature of the outlet of the fin type evaporator 1 is too high, the temperature sensing bulb converts temperature information into pressure information, the pressure information is transmitted into a piston cavity 713 of a valve body 718 through a temperature sensing bulb interface 705 and is positioned between a piston head 714 and a diaphragm 712, so that the pressure between the piston head 714 and the diaphragm 712 is larger than the sum of the pressure below the piston head 714 and the tension of an adjusting spring 704, the piston rod 715 pushes the piston head 714 to move downwards, the throttle head 717 also moves downwards along with the piston head 714, an opening between the throttle head 717 and a circular table-shaped through hole 719 of a throttle block 709 is enlarged, and meanwhile, low-temperature high-pressure liquid flows into the fin type evaporator 1 after the flow rate is increased; conversely, when the temperature sensing bulb detects that the temperature of the outlet of the fin-type evaporator 1 is too low, the temperature sensing bulb converts temperature information into pressure information, the pressure information is transmitted into the piston cavity 713 of the valve body 718 through the temperature sensing bulb interface 705 and is positioned between the piston head 714 and the diaphragm 712, so that the pressure between the piston head 714 and the diaphragm 712 is smaller than the sum of the pressure below the piston head 714 and the tension of the regulating spring 704, the piston rod 715 pushes the piston head 714 to move upwards, the throttle head 717 also moves upwards along with the piston head 714, the opening between the throttle head 717 and the circular table-shaped through hole 719 of the throttle block 709 is reduced, and meanwhile, the low-temperature high-pressure liquid flows into the evaporator after the flow is reduced; wherein the maximum displacement of the upward movement of the piston head 714 does not exceed the position of the bulb interface 705 and the maximum displacement of the downward movement of the piston head 714 does not exceed the position of the balance tube interface 706.
