In some embodiments, the protection level of the first bin 210 may be lower than the protection level of the second bin 220.

In this embodiment, the evaporator 120 does not need to exchange heat with the external environment, so the evaporator 120 is processed according to the weak corrosion resistance standard, and the condenser 110 needs to exchange heat with the external environment, so the condenser 110 is processed according to the strong corrosion resistance standard, for example, in some embodiments, the atmospheric corrosion resistance level of the evaporator 120 is C3, the atmospheric corrosion resistance level of the condenser 110 is C4, and the cabinet 200 may be designed with a local high protection, that is, the protection level of the first bin 210 is lower than the protection level of the second bin 220, and in order to improve the environment suitability of the condenser 110, the condenser 110 may be sprayed, electrophoresed or otherwise processed based on the different requirements of the processed condenser 110 and the evaporator 120 on water resistance and dust resistance.

According to the reactor assembly 100 provided by the embodiment of the application, through the processing design of the local high-protection design of the cabinet 200, local treatment is implemented according to the actual conditions of devices, and the complexity of processing the reactor 130 is reduced, so that the material cost and the processing cost of the whole reactor assembly 100 are directly reduced.
