I have a few simple process-related questions for everyone

I’ll reply with what I think: the purpose of exhausting air at the highest point (3) is probably for use when starting to drive, that is, when water enters for the first time; air tends to accumulate inside the pipes, and gases generally gather at the highest points, so exhaust is carried out through that location.
Item 7 should be an anti-fouling isolation valve: a standard anti-fouling isolation valve is composed of two check valves connected in series. Working principle: The anti-fouling isolation valve consists of two check valves connected in series; when the seal of one of them is damaged, the other still provides sealing to prevent backflow. However, once the seals of both check valves are damaged at the same time, they lose their check function; their safety and reliability are relatively lower, and their working principle is relatively simple. The anti-fouling isolation valve features a drain device added in the middle, based on the standard design; this allows it to prevent backflow contamination even if the seals of both check valves are damaged at the same time.
Item No. 6 should be a pressure relief valve; as for whether it is linked to the liquid level, that depends on the design of the thermal control system
For the two valves at position 4, the valve on top is intended to block the pressure coming from the main pipe, while the valve below is meant to block the pressure from the equipment. It seems that the PI in between is very important; otherwise, there would be no need for such waste
Number 5 is the vent valve at the high point. This valve is normally closed and is used primarily for releasing air during hydraulic testing of the pipelines. It is also used to drain any water accumulated in the pipes when those pipes need maintenance
The small box below the demister filter should be the water drainage tank, and the POLY HOSE should be a plastic pipe
:All those seen before the handshake had no high-point emissions
After starting the vehicle, both of these ball valves are in the open position
