The module mechanism 1 integrates pipelines or valve bodies in the air conditioning system into a whole, so that the number of exposed pipelines can be reduced, and the pipeline cost is further reduced; meanwhile, the first module assembly 11 and the second module assembly 12 are mutually independent and arranged at intervals, so that heat conduction is hardly generated between the first module assembly 11 and the second module assembly 12, high-temperature media flow in the first module assembly 11, and low-temperature media (refrigerants) flow in the second module assembly 12, so that a low-temperature area and a high-temperature area are separated, and the problems of heat loss and waste caused by the fact that a high-temperature flow path and a low-temperature flow path are arranged on the same module and are adjacent in the prior art can be solved.
