Where is the expansion valve located on the Baojun 730?

The expansion valve of the Baojun 730 is located on the air conditioning evaporator. Meaning of Baojun 730: The expansion valve, also known as the throttle valve, is a key component of the automotive air conditioning refrigeration unit installed at the inlet of the evaporator. It serves as the boundary between the high-pressure and low-pressure sections of the automotive air conditioning refrigeration system. The expansion valve is a common component widely used in refrigeration systems. It allows medium-temperature, high-pressure liquid refrigerant to be throttled into low-temperature, low-pressure wet vapor, thereby controlling the flow rate. It is typically installed at the refrigerant inlet of the evaporator. Function of Baojun 730: The expansion valve throttles and reduces the pressure of high-pressure liquid refrigerant from the liquid storage dryer, regulating and controlling the amount of liquid refrigerant entering the evaporator to adapt to changes in the refrigeration load. It also prevents liquid slugging in the compressor and abnormal overheating at the evaporator or vapor outlet. Classification of Baojun 730: There are three main types of expansion valves (throttling devices) commonly used in air conditioning systems: thermal expansion valves, electronic expansion valves, and capillary tubes. Based on structural differences, they can also be categorized into externally balanced expansion valves, internally balanced expansion valves, and H-type expansion valves.
Regarding the location of the expansion valve on the Baojun 730, it is typically installed at a critical point in the engine compartment's air conditioning system, specifically at the connection between the high-pressure AC line and the evaporator. After opening the hood, it can be easily located by following the piping—generally near the firewall or beneath the dashboard, shaped like a valve body. In automotive maintenance, I've noted that this positioning is designed to optimize refrigerant flow control and prevent AC performance degradation. If self-locating proves difficult, avoid forcing disassembly, as the high-pressure refrigerant system may release hazardous gases. For specific details, consulting the vehicle manual or a 4S dealership is advisable. Developing a habit of regular AC inspections can reduce the risk of expansion valve failures.
The Baojun 730 expansion valve is generally located near the air conditioning pipeline in the engine compartment. When searching for it, start from the evaporator source. Its position near the front facilitates maintenance but is often covered with oil stains that need cleaning. The expansion valve plays a crucial role in regulating refrigerant flow. If clogged, it can cause the air conditioning to blow warm air. It is recommended to seek professional repair if any issues are found to avoid improper operation that may damage the system.
The expansion valve on the Baojun 730's engine compartment air conditioning pipeline is not difficult to locate near the firewall, but caution is required due to the high-pressure refrigerant hazard. It's safer to let a technician handle it.
