WebSuperheat is a temperature rise above the saturation (boiling) temperature of a substance for a given pressure. If heat is added to refrigerant when it’s a 100% saturated vapor, it will become superheated. To understand superheat, imagine a pressure cooker full of water and steam. As heat is continually added to the water, the water ... WebWhen the temperature and pressure of the bulb’s charge rises, the powerhead provides the force to open the TXV. When the temperature and pressure of the bulb charge decreases, the TXV closes. As you can see, the sensing bulb determines if a TXV opens or closes.
