Abstract
The air conditioning system and the control method thereof and the release cold mode classification control method are disclosed. Through the regulation and control of the refrigerant flow control assembly, the air conditioning system can switch between multiple working modes. When the air conditioning system works in the release cold mode, the specific connection mode of the supercooler and the accumulator input and output is adjusted by the refrigerant flow control assembly, and the release cold mode is more specifically classified and controlled. Moreover, the temperature change of the accumulator water tank in the supercooling and release cold process is combined, the operation of the supercooling and release cold mode is divided into multiple stages, different stages implement the classification control mode matched therewith, thereby realizing the linkage control of the supercooling control of the outdoor unit supercooler and the supercooling control of the accumulator water tank, maximizing the storage of the accumulator, improving the refrigeration effect of the air conditioning system, and improving the energy efficiency level.
