Abstract

The invention discloses a multi-connection system, including an indoor unit system and an outdoor unit system, the indoor unit system includes a plurality of indoor units, the outdoor unit system includes at least two modules, each of which includes an outdoor heat exchange One end of the outdoor heat exchanger is connected to the multiple indoor units through the liquid pipe, and the other end of the outdoor heat exchanger is connected to the multiple indoor units through the high-pressure air pipe. One end of the low-pressure air pipe is connected to the plurality of indoor units, and the other end of the low-pressure air pipe is connected to the compressor. The multi-connection system also includes a high-pressure communication pipe and a low-pressure communication pipe. The high-pressure communication pipe is connected to the high-pressure air pipes in all the modules, and the low-pressure communication pipe is connected to the suction ends of the compressors in all the modules. It fully increases the utilization rate of the outdoor heat exchanger, reduces the high pressure of the system, and improves the energy efficiency of the whole machine.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a multi-connected system. Background technique [0002] Multi-split system refers to an air conditioning system in which one outdoor unit supplies compressed air to two or more indoor units at the same time. At present, in the modular design of the multi-line system, the connecting pipes between the modules are generally only connected by air pipes, liquid pipes or oil equalizing pipes. The operation process of the modules is relatively independent. Whether the heat exchanger of each module exchanges heat is only related to its own compressor status. When the multi-line system is partially loaded, only a single module is running, and other modules are in a shutdown state, resulting in the ineffective use of the heat exchanger and low energy efficiency of the whole machine. Contents of the invention [0003] The invention provides a multi-connection system, which can fully incr...
