How does an automatic expansion valve work?
Simply so, how does an expansion valve work?
Expansion Valve. The expansion valve removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a vapor in the evaporator. The liquid refrigerant leaving the expansion valve is quite cold. The orifice within the valve does not remove heat, but only reduces pressure.
Furthermore, what is the function of expansion valve in refrigeration? A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator thereby keeping superheat, that is, the difference between the current refrigerant
Keeping this in view, 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.
What is expansion device in refrigeration?
REFRIGERATION AND AIR CONDITIONING. An expansion device is essentially a restriction offering resistance to flow so that pressure drops, resulting in throttling process.
