1, one-to-many central air conditioning is what people often say: an outdoor unit is connected to multiple indoor units, and the indoor units are controlled separately. The outdoor unit delivers refrigerant as required. One-to-many central air conditioning system has the characteristics of high efficiency, energy saving, comfort and beauty. In addition, there is a relatively one-to-one mode, that is, an outdoor unit is connected to an indoor unit, which has obvious advantages over one-to-one air conditioning.

2. The characteristic of one-drive-one structure is that the indoor unit and the corresponding outdoor unit are an independent system, and the power of the outdoor unit is small. The indoor unit and the outdoor unit in each room are controlled separately, but one indoor unit is turned on and the other outdoor unit is turned on, so the power consumption is not small. One-to-many structure is characterized in that a plurality of indoor units and an outdoor unit form a system, and the principle of system configuration is that the sum of outdoor and indoor refrigeration parameters is equal, or the indoor units are properly over-equipped. The air conditioner in each room can be controlled independently, and how much is used, and the larger the house area, the more central air conditioners are used, the more electricity is saved.
