A grey wall on the Haier stand illustrates 'Solar Air Conditioning': solar panels, a battery and a 'PCS' box are linked by illuminated lines to a wall-mounted indoor unit and an outdoor unit on the floor. The hOn app logo and a small screen with notes complete the display, while visitors talk on the glossy white floor nearby.
