Embodiment 1

[0030] In preferred embodiment 1 of the present invention, a refrigerant separation and purification system is provided, specifically, figure 1 A schematic diagram showing an optional structure of the system, such as figure 1 As shown, the system includes:

[0031] The precooler 1 is connected to the gaseous refrigerant outlet of the condenser 3, and is used for precooling the gaseous refrigerant in the condenser 3;

[0032] The refrigerant purification device 2 is connected with the pre-cooler 1 and is used for cooling and purifying the refrigerant pre-cooled by the pre-cooler 1 .

[0033] In the above embodiment, a refrigerant separation and purification system is provided. Due to the addition of sub-cooling in the system, that is, the pre-cooler, the refrigerant containing non-condensable gas is pre-cooled in the pre-cooler before entering the refrigerant. The cooling separation and purification of the purification device reduces the amount of cooling required by the puri...

[0053] In the above embodiment, a refrigerant separation and purification system is provided. Due to the addition of sub-cooling in the system, that is, the pre-cooler, the refrigerant containi...

Embodiment 3

[0068] Based on the refrigerant separation and purification system provided in Embodiment 1 above, an air conditioner unit is also provided in preferred embodiment 3 of the present invention, including the refrigerant separation and purification system as described above.

[0069] In the above embodiment, a refrigerant separation and purification system is provided. Due to the addition of sub-cooling in the system, that is, the pre-cooler, the refrigerant containing non-condensable gas is pre-cooled in the pre-cooler before entering the refrigerant. The cooling separation and purification of the purification device reduces the amount of cooling required by the purification device and shortens the time for cooling, separation and purification, avoids the problem of poor cooling, separation and purification effects caused by insufficient cooling, and improves the efficiency of cooling, separation and purification. Further, the heat exchange performance and energy efficiency ratio...

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a refrigerant separation and purification system for improving purification efficiency, a control method and an air conditioning unit. Background technique [0002] During the working process of the air conditioner, due to the existence of negative pressure refrigerant, air and other non-condensable gases will be mixed into the negative pressure refrigerant. The non-condensable gas circulates in the system with the refrigerant, but it does not condense with the refrigerant and does not produce refrigeration effect. Therefore, the existence of non-condensable gas will affect the heat exchange performance of the air conditioner and reduce the energy efficiency ratio of the air conditioner. [0003] In order to avoid the above problems, the existing air conditioning system needs to carry out cooling, separation and purification treatment on the negative pressure refrigeran...
