How much expansion is in a 100 deg C pipe?
How much expansion is in a 100 deg C pipe?
The 15mm/100m for every 100 deg C is just an approximation of the thermal expansion coefficient of steel.

Where is the expansion valve located in an air conditioner?
If your system uses an orifice tube instead of an expansion valve, most of the procedures are nearly the same, the difference is that the orifice tube is located Inside the line going to the evaporator. Step 1: Locate the orifice tube. The orifice tube will be inside the high-pressure line to the evaporator.
How is the orifice tube different from an expansion valve?
Unlike the expansion valve, the orifice tube is a simple fixed device with no moving parts. It therefore cannot vary the flow of refrigerant into the evaporator, but rather causes a permanent restriction in the system.

When to know if your a / C expansion valve is bad?
The most recognizable symptom of a bad A/C expansion valve is when you turn on your air conditioner and warm air starts blowing out of the vents. This would obviously mean that not enough refrigerant is making its way to the core of the evaporator. Most people will discover this problem at the worst possible time like during the middle of August.
Where is the expansion valve on an AC unit?
The AC expansion valve is found within the air conditioning system of a vehicle. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system. Whenever there is an abundance of refrigerant, the core of the evaporator will get too cold and eventually freeze.
Where is the orifice tube in an AC system?
It is usually installed at the evaporator inlet and works together with the orifice tube to regulate the flow of refrigerant through the vehicle’s AC system. Too much refrigerant flow and the evaporator core will freeze over; too little and the evaporator core will overheat and compromise the efficiency of the AC system.
