Temperature is not a pressure or force acting on a TXV diaphragm. The pressure and forces that typically act on a TXV diaphragm are the evaporator pressure, spring force, and spring adjustment. Temperature indirectly influences the operation of the TXV by affecting the refrigerant pressure.
No, it is not.
Three factors that determine the capacity of a TXV are superheat setting, pressure drop across the valve, and the flow rate of refrigerant passing through the valve. These factors work together to ensure that the TXV maintains proper refrigerant flow to achieve efficient system operation.
Temperature is not a pressure or force acting on a TXV (Thermostatic Expansion Valve) diaphragm. The TXV diaphragm is primarily influenced by refrigerant pressure and spring force to regulate the flow of refrigerant into the evaporator coil. Temperature affects the superheat setting of a TXV but is not a direct force acting on the diaphragm.
Dual port TXV used when system need a large TXV for short periods of time. Dual-port valves have two independent capacities larger port for periods of high load smaller port for periods of normal load TXV capacity is doubled when larger port is open all the way.
If it's a TXV system, it'll be located between the receiver-drier and the evaporator.
Are you sure it has a fixed orifice tube system? Most heavy duty trucks use a Thermal Expansion Valve (TXV) system. In both systems, the metering device (orifice tube or TXV) is located between the condenser outlet and the evaporator inlet.
