What two pressures control the operation of an automatic expansion valve? Spring and evaporator pressures.Click to see full answer. Correspondingly, how does an automatic expansion valve work?The automatic expansion valve (AXV or AEV) is an expansion device that meters the refrigerant to the evaporator by using a pressure-sensing device. The AXV maintains a constant pressure in the evaporator. When the tension is increased, the valve will feed more refrigerant and increase the suction pressure.Also, which constant parameter is maintained in automatic expansion valve? Constant Pressure Expansion Valve or Automatic Expansion Valve. The constant pressure expansion valve keeps the pressure inside the evaporator constant, hence the name. The constant pressure valve maintains constant pressure inside the evaporator no matter what the load inside the evaporator is. Keeping this in consideration, what condition does the automatic expansion valve? Function: The constant pressure or automatic expansion valve responds to outlet pressure. It meters liquid refrigerant to the evaporator, maintaining a constant evaporator pressure. Refrigerant flows at a rate that exactly matches compressor capacity. A typical AXV is shown in Figure 3.What controls the flow of refrigerant through the evaporator?The refrigerant vaporizes from the heat it absorbs heat in the evaporator. Flow control device (expansion valve): This controls the flow of the liquid refrigerant into the evaporator. Control devices usually are thermostatic, meaning that they are responsive to the temperature of the refrigerant.
