Thermal relief is required on any liquid line where there is heat input and the line does not have an open path to flow to in the event of a failure scenario (blocked outlet, instrument air failure, general or single power failure, etc.).
A classic example is the blocked outlet case of the cold side of a shell and tube heat exchanger. If the cold side flow is blocked between the discharge of a pump and the outlet of the exchanger the heating medium will continue to transfer heat and the liquid will expand and have the potential for thermal relief.
Thermal relief is also required for cooling water exchangers on the cooling water side; however, some facilities keep administrative controls (car sealed open valves) on the cooling water lines to ensure such as scenario does not occur. These facilites would not typically provide thermal relief devices on their cooling water exchangers.
No, the "liquid line" is the little line, also called the "high side" line. When operating properly, it should be hot, sometimes very hot.
Not directly.
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
suction line liquid line
A relief valve is fitted in the suction line to protect the system from excessive negative pressure, which can occur due to blockages or sudden changes in flow conditions. By allowing excess pressure to vent, the relief valve prevents cavitation, which can damage pumps and other components. Additionally, it helps maintain optimal operating conditions and ensures the reliability and efficiency of the system.
No, thermal and line printers are two different things. "Line" printers are referring to a form of "Dot-Matrix" printers. "Thermal" printers burn a special paper to form characters and symbols.

The suction line is the big one. This line should be cold when the unit is on. The small line is the liquid line.
A 2002 Ram truck does not have an expansion valve. The ac system uses an orifice tube that is made into the liquid line.
Yes, it is only serviced as part of the liquid line. The liquid line is the aluminum line that runs along the passenger side inner fender.Yes, it is only serviced as part of the liquid line. The liquid line is the aluminum line that runs along the passenger side inner fender.
Converter relief valve ensures high line pressure does not flood/overrun the solenoid.
d
Refrigerant in the liquid line is in a liquid state. It has condensed from its vapor form into a liquid due to the pressure and temperature conditions in the line. This liquid refrigerant is ready to enter the evaporator coil to absorb heat and undergo the phase change process again.
How do you calculate the production line personnel required?
The ac orifice is made into the center of the liquid line. The liquid line is the one that runs along the passenger side inner fender.The ac orifice is made into the center of the liquid line. The liquid line is the one that runs along the passenger side inner fender.

Liquid refrigerant charging of a system is normally accomplished in the liquid line. For example, when a system is out of refrigerant, liquid refrigerant can be charged into the king valve on the liquid line or receiver.
