There are at least the following problems in the development of the outdoor unit:

[0003] 1. There are many external sensors on the unit (more than 20 sensors), and the external wiring is complex.

[0004] 2. Due to the limitation of the vehicle body size, there is no place to place the electrical control box on the outdoor unit.
