FAQ:

Q: What happens to the refrigerant when it enters the metering device?

A: As the liquid refrigerant enters the metering device it changes temperature and pressure. A partial amount of the liquid refrigerant flashes into a refrigerant gas or vapor. The refrigerant does this as it leaves the metering device and enters the evaporator coil. Thermostatic Expansion Valve – Also referred to as the TEV or TXV for short.

Q: What is metering in HVAC system?

A: Metering devices installed by the manufacturer of the HVAC system partially define the efficiency of the equipment. Lower efficiency HVAC systems have fixed orifice types. The higher efficiency systems have thermostatic expansion valves. TXV’s installed in the HVAC air conditioner or heat pump system gives higher efficiency.

Q: What is the purpose of a fixed orifice metering device?

A: This allows a specific amount of refrigerant, based on demand, to be metered into the evaporator coil. The fixed orifice metering device allows the same amount of refrigerant to enter the coil no matter the demand. As the liquid refrigerant enters the metering device it changes temperature and pressure.
