AI Technical Summary
In traditional multi-split HVAC systems, the outdoor units are centrally located, which makes the cooling/heating performance susceptible to the installation environment. In addition, the system occupies a lot of space, which restricts installation and results in insufficient cooling capacity and large temperature fluctuations.
The compressor unit and the first heat exchange unit are set up separately, and the operation of each first heat exchange unit is independently controlled in different installation environments. They are connected by gas pipe groups and liquid pipe groups to achieve flexible installation and independent control.
It optimizes the overall operating efficiency and indoor comfort of HVAC systems, reduces the impact of the installation environment on system performance, and improves installation flexibility and adaptability.
