What is the acronym often used for thermostatic expansion valve?

• TAV

• TVX

• TXV

• TEV

Where is the thermostatic expansion valve located in the system?

• Inside the condenser

• Just before the evaporator

• After the evaporator

• Before the compressor

What does the thermostatic expansion valve control?

• The flow of air

• The temperature of the room

• How much refrigerant can pass into the evaporator

• The speed of the compressor

What happens if the thermostatic expansion valve fails?

• The compressor may get damaged

• The refrigerant leaks

• The system stops cooling

• The evaporator freezes

What is the purpose of the sensing bulb in the thermostatic expansion valve system?

• To detect the temperature of the superheated refrigerant

• To control the temperature of the evaporator

• To measure the pressure of the refrigerant

• To increase the efficiency of the compressor

What is the effect of the thermostatic expansion valve on the refrigerant pressure?

• Does not affect the pressure

• Randomly changes the pressure

• Decreases the pressure

• Increases the pressure

What is the main component that moves to allow more or less refrigerant to pass through in a thermostatic expansion valve?

• The capillary tube

• The needle or pin

• The diaphragm

• The spring

What is the consequence of setting the superheat incorrectly in a thermostatic expansion valve?

• The refrigerant may freeze

• The evaporator may overheat

• Liquid refrigerant may enter the compressor

• Increased energy consumption
