Gram production and trading group:

The expansion valve of the air conditioner reduces the pressure of the refrigerant liquid. This reduction in pressure is because it allows the liquid to be converted to vapor in the evaporator. Refrigerant gas enters the expansion valve in liquid state with high temperature. When the refrigerant comes out of this valve, its pressure will decrease and at the same time its temperature will also decrease.

The different parts of the expansion valve include:

  2. Diaphragm
  3. Inlet
  4. Orifice
  5. superheat setting spring
  6. Outlet
  7. Pushpin
