Working principle of automotive air conditioning solenoid valve

The working principle of the automotive air conditioning solenoid valve is to generate magnetic force through the electromagnetic coil to control the opening and closing of the valve.

When the electromagnetic coil is energized, it generates magnetic force to attract the magnetic core, causing the valve to open and the refrigerant to start circulating;

When the electromagnetic coil loses power, the magnetic force disappears, the valve closes, and the refrigerant circulation stops. Through this method, the solenoid valve can precisely control the flow of refrigerant, thereby achieving temperature regulation.

The core function of the air conditioning compressor solenoid valve is to control the flow of refrigerant, protect the compressor, and maintain the safe operation of the system.

The following is a detailed explanation of the specific functions and principles:

1、 Main function

Prevent liquid impact and shutdown protection

When the compressor stops, the solenoid valve quickly cuts off the refrigerant circuit, preventing high-pressure liquid refrigerant from flowing back to the compressor and avoiding mechanical damage caused by liquid refrigerant impact (liquid hammer) during restart.

At the same time, the fast closing characteristic of the solenoid valve ensures system pressure balance and extends the life of the compressor.

Precise control of refrigerant flow direction

The solenoid valve controls the opening and closing of the valve by turning on and off the coil, achieving directional flow of refrigerant in the system. For example:

At startup: The solenoid valve opens, the refrigerant circulates normally, and the compressor starts working.

During shutdown: The solenoid valve is closed to block refrigerant backflow and ensure that the system pressure gradually returns to balance.

Safety and leakage control

Leakage protection: The solenoid valve adopts a magnetic sleeve sealing design without moving sealing components, significantly reducing the risk of leakage.

Internal leakage suppression: The structure is simple and easy to control, which can reduce internal leakage or even achieve zero leakage, suitable for corrosive or toxic media.

Efficient response and energy conservation

The response time of the solenoid valve is as short as milliseconds and the power consumption is low. For example, a direct acting solenoid valve can quickly complete valve action and reduce continuous power consumption through a self-sustaining design.
