Where the refrigeration changes in a refrigeration system?
at the metering device before the evaporator
Define flash gas and how it applies to the net refrigeration effects of the refrigeration cycle?
FLASH GAS - Instantaneous evaporation of some liquid refrigerant at the metering device due to pressure drop which cools the remaining liquid refrigerant to desired evaporation temperature.This flash gas cannot absorb any heat having a negative effect on the net refrigeration cycle

What component separates the high pressure and low pressure sides of the air conditioning system and acts as a metering valve to control the flow of refrigerant?
That sounds like the expansion valve.
Where does flash gas get created?
As the refrigerant exits the metering device
When the refrigerant passes through the metering device some of it starts to flash from a liquid to a gas?
when the refrigerant passes through the metering device, some of it starts to flash from a liquid to a gas because
What are the major parts of refrigeration?
Compressor, condensor, metering device, evaporator.
Where does the pressure in a refrigeration system change?
at the metering device before the evaporator
Function of expansion valve?
Metering device The metering device controls the flow of liquid refrigerant through the system. The liquid enters at a high-pressure, high-temperature, sub-cooled state and leaves as a low-pressure, low temperature, expanded liquid state. Accurator Piston and Thermostatic Expansion Valves are the most widely used metering devices. Accurator Pistons are widely used because of their low cost and flexibility. The piston can easily be changed to match the capacity of the condensing unit. The Thermostatic Expansion Valve (TXV) is the most efficient type of metering device. The TXV automatically adjusts the flow of the liquid refrigerant based on the superheat of the refrigerant leaving the evaporator coil. As the load on the evaporator increases, the TXV increases the flow of refrigerant. This maintains the proper superheat. The TXV is efficient throughout a variety of system operating conditions, while the accurator is efficient only under designed conditions.
How do you change high temperature refrigerant and high pressure refrigerant in to low temperature refrigerant and low pressure refrigerant?
You cool it and run it through a metering devise.

What type of refrigerant metering device is used on most refrigerators?
A curator
