Honeywell Type AEL 3 AEL-222213 Automatic Expansion Valve For Air
Conditioner
Automatic Expansion Valve Working Principle:
1. In the automatic expansion valve, the spring pressure along with
the atmospheric pressure acts on the diaphragm and pushes it down.
As a result, the needle also tends to move down away from the seat
leading to the opening of the valve.
2. The evaporator pressure pushes the diaphragm in an upward
direction. Due to this, the needle tends to move in an upward
direction towards the seat to close the valve.
3. In the normal running condition of the plant, the valve
maintains equilibrium between the evaporator pressure and the
spring pressure and maintains a certain opening of the valve to
allow the flow of refrigerant through it.
4. The automatic expansion valve maintains the pressure inside the
evaporator constant and automatically as per the setting of the
spring pressure.
5. When the refrigeration plant with the constant pressure valve is
stopped, a certain amount of the refrigerant remains inside the
evaporator and creates pressure inside the evaporator. This
pressure acts against the diaphragm and keeps the valve closed.
When the refrigeration plant is started again, the evaporator
pressure reduces and the constant pressure expansion valve opens
again.
