The invention provides a two-pipe heat recovery multi-split air conditioning system and a refrigerant flow direction control device and method. The two-pipe heat recovery multi-split air conditioner system comprises an outdoor unit refrigerant operation assembly, a refrigerant flow direction control device, a mode converter and a plurality of indoor units. The outdoor unit refrigerant operation assembly is connected with the mode converter through the refrigerant flow direction control device. The mode converter is connected with the multiple indoor units. The refrigerant flow direction control device is configured to obtain the refrigeration demand quantity and the heating demand quantity of the multiple indoor units, determine the unit operation mode according to the refrigeration demand quantity and the heating demand quantity of the multiple indoor units and control the flow direction of a refrigerant according to the unit operation mode. According to the invention, the flow direction of the refrigerant can be accurately controlled, so that different unit operation modes can be automatically adapted.
Description
technical field [0001] The present disclosure relates to the technical field of air conditioning, in particular to a two-pipe heat recovery multi-connection system, a refrigerant flow direction control device and method. Background technique [0002] The heat recovery multi-connection system is a multi-connection system that can realize part of the internal cooling and part of the internal heating at the same time. In the technology known to the inventors of the present disclosure, the heat recovery multi-line is mostly a three-pipe multi-line, that is, the external unit is connected to three pipes, and the unit components and pipeline structure are more connected than the known heat pump system. for complex. This makes installation and maintenance more inconvenient for users. In related technologies, a two-control multi-connection system may be used. Contents of the invention [0003] The inventors of the present disclosure have discovered that the known two-pipe multi...
