Abstract

The invention discloses a multi-online system. The multi-online system comprises an outdoor unit (1) and a plurality of indoor units connected with the outdoor unit (1) through a third reversing valve (2). Independent control is achieved on the work states of the indoor units. The multi-online system has a first work mode that at least two indoor units are in different work states, a second work mode that the indoor units are in the heating state at the same time, and a third work mode that the indoor units are in the refrigerating state at the same time. According to the multi-online system, switching of any modes of the multiple indoor units can be met, the energy utilization rate is increased, and the using requirement of users can be conveniently met.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a multi-connected system. Background technique [0002] At present, in the existing one-to-two multi-connected system, only two indoor units can be cooled or heated at the same time. , Another built-in mechanism heating demand, so it is difficult to meet the user's demand for cooling and heat, making the energy utilization rate low. Contents of the invention [0003] The embodiment of the present invention provides a multi-connection system, which can meet the switching of any mode of multiple internal units, not only improves the energy utilization rate, but also can conveniently meet the use needs of users. [0004] In order to achieve the above purpose, the embodiment of the present invention provides a multi-connected system, which includes an outdoor unit and multiple indoor units connected to the outdoor unit through the third reversing valve. The workin...
