  • Publication number: 20220196259
    Abstract: A three-pipe, multi-split system and a control method thereof. The three-pipe multi-split system includes an outdoor unit, a multi-split indoor unit, and a hydraulic module. By optimizing a refrigerant system, the phenomenon that a refrigerant is throttled before flowing through a refrigerant heat dissipation module or supercooled when passing through a plate heat exchanger which causes a relatively low temperature of the refrigerant entering the refrigerant heat dissipation module and consequent condensation on the refrigerant heat dissipation module to produce condensate water and then causes a damage to a compressor frequency conversion module can be avoided. In addition, more refrigerant is caused to flow through the refrigerant heat dissipation module to reduce the temperature of the module.
