Where is the TXV sensing bulb mounted?

The TXV (Thermostatic Expansion Valve) sensing bulb is typically mounted on the outlet of the evaporator, specifically on the suction line. This location allows the bulb to accurately measure the temperature of the refrigerant, ensuring the valve effectively regulates the flow of refrigerant into the evaporator based on the cooling demand. Proper placement is crucial for optimal system performance and efficiency.
