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.
The function of an expansion valve is to regulate the flow of a substance. One example is a thermal expansion valve which regulates the flow of cooling substances within a device.
Changes the refrigerant from liquid to vapor.
where is the expansion valve located
how do you replace the expansion valve
No, it uses an expansion valve.No, it uses an expansion valve.
Unsure what you are asking about. WHAT expansion valve - in what system?
the expansion valve is on the passenger side firewall in the engine compartment.
The 2005 Nissan air conditioning compressor expansion valve is located on the bottom of the compressor. The expansion valve should be labeled as such.
The expansion valve, on your 1998 Honda Accord, is located just before the thermostat housing. You can follow the water hose from the radiator to the expansion valve.
There is no expansion valve. The metering device is called a expansion valve should be located in the small line on the condenser it will be located near the line at the connection
the expansion valve is connected to the evaporator under the dash, have fun!!!
It is not.. A globe , needle , ball valve are used for throttling For expansion either a shock absorber , diaphragm tank or air chamber are used to allow for expansion
