Question

What is the full form of TEV or TXV?

1) Thermostatic Expansion Valve
2) Thermal Exchange Valve
3) Throttle Expansion Valve
4) Temperature Control Valve

Answer 1

The full form of TEV or TXV is Thermostatic Expansion Valve, used in cooling systems to regulate refrigerant flow. It ensures consistent superheat in the refrigerant leaving the evaporator.

Step-by-step explanation:

The full form of TEV or TXV is Thermostatic Expansion Valve. The Thermostatic Expansion Valve plays a critical role in refrigeration and air conditioning systems by regulating the flow of refrigerant based on the cooling demand. The valve aims to maintain a consistent superheat of the refrigerant as it leaves the evaporator.

Now let's define some related terms:

1. Vaporization is the phase change from a liquid to a gas.
2. Evaporation is vaporization that occurs at the surface of a liquid below its boiling point.
3. Condensation is the change from a gaseous state to a liquid state.

Effect of Temperature on Evaporation

Higher temperatures lead to an increased rate of evaporation because the added energy allows more molecules to escape from the surface of the liquid into the gas phase.
